Global Vision of the LESS Competition The Valencian Institute of Building, with the support of the Consum cooperative and Climate-KIC, launched an international competition in July 2013, the “LESS competition”, aimed at supporting innovative solutions to improve energy efficiency in commercial premises.

The competition and the subsequent development of the selected ideas are part of the Climate Market Accelerator (CMA) program within the Climate-KIC platform, which is designed to foster the development of innovative products and services that contribute to reduce climate change and help these new solutions overcome existing barriers in order to enter the market.

Consum carried out a preliminary analysis in some of its supermarkets and detected the need to improve the efficiency of the facilities in order to reduce electricity consumption, and thus the CO2 emissions, so as to meet the objective of mitigating and adapting to climate change.

15% of the electricity used in a standard supermarket is used for air conditioning and 16% for lighting. This translates to approximately a total of 200 000 kWh per year. The electricity consumption for air conditioning is probably similar to that of any other establishment, however if we consider that supermarkets have large food storage areas that require industrial refrigeration, the consumption percentage can increase to about 70%, with the remaining 30% being used for lighting, ovens and other smaller needs.

Thus, introducing energy saving measures in shops can lead to a significant reduction of energy consumption, and therefore, a significant decrease in CO2 emissions into the atmosphere.

With the purpose of introducing new ideas into the market, the LESS (Low Energy Solutions for Shops) competition was launched in order to select the most efficient and innovative solutions and help implement them in existing buildings.

Aim of the competition

The competition focused on the development of innovative products, technologies or services which could be implemented in commercial premises and improve the energy efficiency and thus, a decrease in CO2 emissions, thereby contributing to the required mitigation and adaptation to climate change. The improvements had to focus on reducing the energy demand through passive systems; increasing the facilities’ performance; include renewable energies; or improve the energy consumption management processes.

Challenge

All proposals had to be innovative, versatile and easily implemented in existing buildings regardless of the building type and location. The proposals were to be framed in one of the following applications:

Lighting

Reducing the energy demand for lighting through passive or active measures.

Air conditioning

Reducing the energy consumption when heating or cooling commercial premises.

Although the consumption reduction from refrigeration equipment for the storage, preservation and exhibition of food products was not the initial goal, proposals which combined solutions to reduce consumption from lighting and/or air conditioning with an improved efficiency from industrial refrigeration equipment were positively assessed. Similarly, the use of intelligent automation systems or the incorporation of renewable energy were taken into account.

Criteria The competition was open to any person or entity based in the European Union, whether an individual or legal entity, including freelancers, SMEs, public bodies, NGOs and research groups. The proposals had to be framed, according to their degree of development, in one of two categories:

- Early stage idea: solutions in an initial development stage

- Close to market: solutions in a more advanced development stage, which are almost ready to be introduced into the market and which can be easily implemented in an existing supermarket.

Evaluation process

The competition was launched on 11 July 2013 and closed 12 weeks later on 6 October. Once all the proposals had been received, the Valencian Institute of Building designed an evaluation process based on three phases: with the participation of the general public through a popular voting system; with experts in each of the features being tested and represented by the Technical Committee; and with representatives from key bodes which made up the Strategic Committee and who were in charge of assessing the final commercial viability.

1. Initial review

The Valencian Institute of Building (IVE) conducted the initial review of the documentation submitted by each candidate based on the requirements stated in the competition notice and on the eligibility criteria, without considering the proposal from a technical point of view. Proposals which passed this first stage were published on the website for the public to vote.

CMA – LESS competition Summary report Instituto Valenciano de la Edificación 7

2. Intermediate technical evaluation and popular vote

The porposals were then assessed from a technical point of view by the members of the Committee of Experts. A final grade was awarded to each project resulting from a partial evaluation of each of the assessment criteria. The result of the popular vote through the website was also taken into account to select the finalists.

3. Final evauation

The Technical Committee and the Strategic Committee met during the Environmental and Energy Fairs (13 November 2013) to assess the finalists’ proposals taking into account their applicability to the market and then selected the winners of the competition.

Results

In a meeting held on 13 November, the members of the monitoring committees selected two proposals within the “Close to market” category so that they could continue to develop the idea put forward with the technical and financial support of the “Climate Market Accelerator” programme and with the help of a grant taken from the budget assigned to the Valencia region for the Incubation Programme (Low Carbon Incubator).

The projects selected from the “Close to market” category were “OPTISINERGY SOLUTION”, presented by Mr. Ignacio Urchueguía Schölzel, and “AqH (Accumulation in quiet Hours)”, by Mr. Jorge Aguilar Segura.

Both teams had to draft an “Implementation Plan” to define a pilot which could be implemented in a specific Consum supermarket with the support of a team of energy experts. The aim of the Plan was to assess the technical and financial viability of the solution proposed and determine the following stages in the programme as well as the funding to be allocated to each proposal.

The corresponding Implementation Plans were submitted in February 2014 and were then assessed by a team of experts (consultants) created for this purpose. The consultants’ opinion was announced in a technical and financial viability report, which was agreed and discussed in a meeting, during which it was decided that the “AqH” proposal would be given the support required to develop and implement the idea in the market. A pilot test of “Optisinergy” was dismissed but a small financial aid was given to help with the commercial promotion of the idea of the provision of ESCO services aimed at small businesses.

Regarding the “Early stage idea” category, the winning project was “Smart-SP” presented by Javier Sanchís from UPV (Polytechnic University of Valencia) and who was awarded a scholarship to attend “The Journey” summer school organised by Climate-KIC in 2014.


Coordination and monitoring mechanisms The mechanisms set to ensure the progress of the competition were based on the coordinated work of the members of the Monitoring Committees (MC): the Technical committee and the Strategic Committee and “Bet on LESS” partnership.

The Valencian Institute of Building was in charge of defining, launching and deciding the winner of the competition with the support of the staff from the Consum cooperative, which had been chosen for that purpose. For the technical and commercial assessment of the proposals, two monitoring committees were created; these were made up of the following bodies and representatives:

SOLUTION CHALLENGE NOTES

DYNAMIC CLOSE LOOP GEOEXCHANGER

- Reduction of HVAC energy - Use of renewable energy

sources

Geoexchanger closed loop to geothermal installations with higher heat transfer ratio. High degree of innovation, patent on-going, minimal space requirements, CO2 emissions reduction from 40 to 70% compared with traditional energies, renewable energy, ease of manufacturing, applicable in both new and existing buildings

The ESCO of the employees

- Reduction of lighting energy

- Smart automated systems

The aim of this proposal is to popularize the rational use of energy in the sense of sharing technology and make Consum workers play an active role. The objective is to test an open source energy monitoring system for supermarkets and, once behavioural energy savings have been indentified, to launch a 50/50 campaign. It aims to establish some energy reduction targets, and share the economic savings amongst the company and its workers. Although the proposal is based on a simple energy monitoring system, the innovative part of the proposal is the involvement of the human behavior, the idea that the workers are an important part of the business model. It would be a service based on the energy management devices already implemented in Consum.

Smart-SP - Smart automated systems - Reduction of HVAC energy

It is a computer program to operate HVAC systems using weather predictions and predicitive control. The most innovative aspect of this product is that is able to calculate optimal dynamic set-points for HVAC systems using weather forecast and predicition models for different variables such as HVAC energy consumption, room temperature or relative humidity. Ease of implementation and replicability.


OptiSinergy Solution


- Smart automated systems - Reduction of HVAC energy

The proposal is based on a hybrid system that combines smart monitoring of energy consumption with the control of HVAC systems in order to take advantage of energy and economic savings generated by the possibility of storing in the night time, inside the retail space, large amounts of thermal energy in an innovative structure based on PCM materials that engages the racks existents. Innovative aspect: savings are shared by clients and the operator under the ESCO model. Reduction of the required power – economic impact. Ease of implementation and replicability.

ConsumLess


- Smart automated systems - Reduction of HVAC energy - Use of renewable energy

sources

New integrated energy system as an upgrade of existing plants, enhancing their energy performance and producing the whole energy needed by the building thorugh renewable energy sources. Focused on achieving a Zero Energy Building. Although the proposal is focused on the design of the building, and perhaps more oriented to new buildings instead of existing buildings, the committee has decided to give them the opportunity to defend his proposal since it is very well worked.

LIGHTHERMY - Reduction of lighting

energy

Energy recovery system for LED lighting installations. The system retrieves up to 60% of the electrical consumption in applied energy usable for any kind of heating/cooling system. It maintains LED lighting systems at a lower temperature, this increases LED efficiency by 10% and increases its durability by 30%. High degree of innovation.

E2S-TOOL



Simulation tool to quantify the energy savings for each solution, depending on the specific configuration of the supermarket. To develop a specific tool taking as starting point the data input from a typical CONSUM Supermarket generating a dynamic model. The most innovative aspect of the tool is that it will be focused on quantifying which technological solution is the best for each supermarket. CONSUM supermarkets are nowadays being monitored, but this tool will provide a dynamic model to improve the enery performance of the supermarket.

Close to market – rejected proposals:


Savex ESL Cover Plate


Design-registered solution for the efficient conversion of all T12 and T8 fittings to Electronic Ballast and T5 tubes. This proposal has been rejected mainly because the product has already been registered and marketed. One of the basic requirements of the competition was that the product had not been put into the market.

Plataforma on-line ENERGY SENTINEL - Smart automated systems

Online-platform for controlling and managing energy consumptions. This type of systems has already been installed in Consum. Besides, the online-platform has already been registered and marketed. On of the basic requirements of the competition was that the product had not been put into the market.


CYSMETER - Smart automated systems

The system does not introduce a high degree of innovation. It is a network analyzer. The system would make sense if there is no access to the electrical panel, but in a supermarket each system has its own electrical panel and the access for measuring is possible.

GIANT the Wave’ s Power


- Use of renewable energy sources

- Reduction of HVAC energy

The proposal raises the use of waves of the sea to produce electricity and with this electricity desalinated water, hydrogen low cost, and eliminate the CO2. Although the technology is innovative, it raises a difficulty for the implementation and replicability. The system has been used in Venice for obtaining lighting, but it is very difficult to replicate it, since most of supermarkets are not situated close to the water.

MyEnergyMap



The system is an energy monitoring system aimed at the business processes Through the process orientation, it would be possible to calculate the carbon footprint of each product. This is not focused on the challenges of the competition.

new design lampshades and LED technology


Use of LED lighting. The product is not innovative at all. This type of lampshades has already been implemented in CONSUM.

DIMMIT - Reduction of lighting

energy - Smart automated systems

It is a management system for indoor LED lighting to optimize lighting energy consumption for a given level of visual comfort. The implementation of the system does not bring a huge competitive advantage, it is a potentiometer.

sm4BS - small magnitudes for Big Savings



The proposal aims to distribute sensing devices throughout the supermarket in order to gather smart information so as to help Consum to save energy and money. The degree of innovation is low, sensors only collect data about temperature, lighting, energy consumption, but the system does not perform any control or management depending on collected indicators.

EnerXi



Tool for controlling and managing energy consumptions in buildings. The degree of innovation is low, this type of systems has already been installed in Consum.

SUNLIGHT PIPELINES


Natural lighting system that consists of a collector dome placed on the roof of the building, a line of highly reflective anodized aluminium several feet facing the ceiling reflecting solar rays inside until the diffuser is installed inside the space and through which illuminates the space. The degree of innovation is low, this type of products can be found in the market. Besides, the presence of skylights in the roof supposes a safety vulnerability.

EURO


- Smart automated systems - Reduction of HVAC energy - Use of renewable energy

sources

The proposal aims to develop a general strategic plan for saving, modernisation, exploitation improvements, progress in sustainability and generation of own resources. The proposal is poorly defined and not focused on the challenges of the competition.


Early stage ideas - finalist proposals:


all-in design - Reduction of lighting

energy - Reduction of HVAC energy

The proposal aims to create a new concept of supermarket based on a sustainable design taking into account different aspects. Proposal very well justified and elaborated.

Accumulation in quiet hours


- Reduction of HVAC energy - Use of renewable energy

sources

Proposal very well justified and elaborated. In fact, it has been the unique proposal that has taken data about energy consumption in CONSUM in order to justify the analysis. Although the proposal deals with several aspects to obtain energy savings at the supermarket, It would be recommendable to focus the proposal on the development of PCMs.

Early stage ideas - rejected proposals:


Statistic is the solution!



The objective is to carry out an ex-post statistical analysis on the energy consumption determinants in all the supermarkets of CONSUM. The proposal does not raise a specific product or solution to improve the energy performance of the supermarkets, just raises a statistical analysis of the data provided by Consum without implementing improvement measures.

NoCo2


- Smart automated systems


- Use of renewable energy sources

The proposal is focused on using several strategies: passive downdraught evaporative cooling, night time convective cooling and natural light thorugh the use of skylights. The proposal is not a new idea, it is the combination of several existing technologies. Low degree of innovation.

GER SMART AIR - Reduction of HVAC energy

The proposal raises the implementation of a heat recovery ventilation system. Product already developed and marketed by the company Zehnder. No complete documentation. No justification of the proposal. No description of the team.


Final evaluation

On 13 November 2013 the members of the Monitoring Committees met for the final deliberation and to announce the jury’s final decision. In order to reach a final decision, the 7 finalists from the “Close to market” category and the 2 finalists from the “Early stage idea” category were invited to defend their proposal one last time by making an “elevator pitch” presentation of their idea.

After comparing the pros and cons of all the proposals, the members of the Assessment Committees agreed to the following:

• The proposal “Accumulation in quiet hours” was changed from the “Early stage idea” category to the “Close to market” category, for it was considered that the proposal is developed enough to be closer to the market stage.

• The proposal “Smart SP” was changed from the “Close to market” category to the “Early stage idea” category, for it was considered that the proposal had not taken into account the business plan and product marketing, nor the calculations relating to the product’s payback period, nor the energy and financial savings that would result from implementing the idea in a supermarket.

Regarding the LESS Competition winning proposals:

• In the “Close to Market” category, the winning proposals (both in first place), and which will receive support to enter the market with the possible implementation of the idea in a Consum supermarket are “Accumulation in quiet hours” and OptiSinergy Solution”. Both teams passed to the next stage where they were given technical advice to develop an “Implementation plan” for a minimum pilot version in an existing supermarket. The aim of the plan was to assess the technical and financial viability of the solution proposed and determine the following stages of the programme as well as the funding to be allocated to each proposal.

• The winning proposal in the “Early stage idea” category was “Smart SP” and the participant will have the opportunity of attending “The Journey” summer school organised by Climate KIC with the aim of developping a business and marketing plan for the product.

• The “The ESCO of the employees” proposal received a special mention since the idea of including the behaviour of the employees as an important part of the business model is considered to be an innovative idea. Similarly, the “Consum Less” proposal also received a special mention considering it has been very nicely crafted and with the right focus in order to achieve zero-energy supermarkets, considering the introduction and combination of various systems and technologies.

Proposal description Reduction of energy consumption in commercial refrigeration facilities by energetic accumulation in quiet hours

2 % of the operating expenses of a supermarket chain are due to the cost of energy, therefore in addition to reducing energy consumption for environmental reasons it will also generate great cost savings.

71 % of the consumption of facilities similar to CONSUM is focused on the Industrial Refrigeration + Cimate Control

Then, it is reasonable to think that where it is more effective to make efforts in order to reduce energy consumption is where it is consumed.

Where and How can we act in a reasonable and effective way?

It is easy to obtain significant savings on some items of lower consumption with little investment and to dedicate the great effort to reduce the consumption in Climate Control and Refrigeration

• Reductions of over 30% on lighting only changing the type of fluorescent tube and the type of ballast

• Reductions of 15% using recuperators. We can use the excess of heat from the ovens to heat the facilities in winter


• Reduction of 30%. Taking advantage of synergies between cooling and heating facilities we can recover almost all the heat of condensation in winter and sanitary hot water during all year

• Using high-efficiency displays and sustainable equipment production we can reach over 60% savings

• Producing cooling energy at night time with more favorable condensation temperatures and later on storing it and consuming that energy in the day. This way we will get extra savings of about 18% and with hourly discriminationin the bills we will get substantial financial savings.

Distribution of cooling and air conditioning consumption in type installations along the year

Analyzing consumption graphics, the store is climatized in summer using the losses caused by opened displaycases.

Just this effect causes extra consumption since the COP of the refrigerating system is much lower than that of climate control due to their evaporation temperatures.

Consumption reduction in air conditioning and refrigeration: Efficiency improvement in display cases

77% of the energy required by conventional open refrigerated cabinet is to mitigate losses by convection, 74% of this energy is used to cool the air curtain, not to preserve food.

The best solution lies in the development of a range display cases designed in a way that convection losses will be eliminated.

These changes in food display cabinets, which are the major energy consumers in a supermarket, lead to savings of over 60%.


To the reduction of consumption in the display cases we can add the accumulation of energy

Having decreased so much the power required by the display cases it allows us to think in designing a system to accumulate the energy in order to reduce the energy costs using a double electric rate.

To achieve this effect we must redesign completely the concept we have of refrigeration and air conditioning in supermarkets.

How to storage this energy?

In the form of latent energy taking adavantage of the condition change of some substances.

The heat required to raise the temperature of 1 Kg of ice is 2.090 J / (kg·K). However to melt this 1 kg of ice we would need 334.000 J for which the capacity of storaging energy taking as base the water in its condition change phase is nearly 160 times higher.

We can use the design of eutectic materials used in food preservation for designing a container capable of storing a large amount of thermal energy: ICE BALLS

Advantages of the proposed installation:

• Disappears the central of the positive cooling circuit because it is used the central of air conditioning circuit for storing energy in night periods .

• It accumulates energy produced in hours in which room temperatures are much lower and the energy cost is almost half .

• Condensation heat for heating can be accumulated .

• It can be used a support for the geothermal condensation to reduce much more condensation temperature and improveing the COP .


• By using horizontal scroll equipment in low temperature, condensed by stored energy to energy costs and to a COP higher than usual in hours day, we will improve the efficiency of the Low temperature installation in a very important way .

• Air conditioning central which during the night usually is switched it is made profitabable in order to produce energy which will be used in the day with a quick amortization of the installation.

• The use of highly efficient displays makes that the energy to be stored is small and the space for the accumulator ICE BALLS would be the same which the central would used + , thus there is no increase in the space required .

• The tax on fluorinated gases is minimized due to the use of confined facilities and refrigerant R- 407F

Differences current consumption vs efficient:

60% of the consumption in refrigeration, which is the consumption of positive refrigeration circuit, we will be done in quite hours with a very low cost and the negative having accumulated energy with condensation temperatures much more lowel during the night.

The increase of the investment estimated for a type store would be: 117.500€

Proposal description Our proposal is based on a hybrid system that combines smart monitoring of energy consumption to the control of air conditioning systems, ventilation and lighting for take advantage of opportunities of energy and economic savings generated by the possibility of storing in the night time, inside the retail space, large amounts of thermal energy (at 21 ºC) in an innovative structure based on phase change materials that engages the racks existents.

Optisinergy solution part of an innovative conjunction of systems and services that generate savings that are shared by clients and the operator under the ESCO model. The new business model is based in the savings in energy used for air conditioning and lighting and total amount of money saved for paid the power contracted.

Figure 1. Conceptual scheme of the solution Optisinergy

The savings goes to the feasibility study and energy efficiency project, pay the 'fees' of the ESCO and generates savings in the energy bill for the customer, which is consolidated and


increase in the middle-long term.

Materials and components

The system architecture is structured in three levels:

1. Simulation and control, 2. Smart optimization. Automatic control. 3. Free energy storage.

The main components are the base model simulation, the Carlo Gavazzi EWG platform, the control software and between 7.000-14.000 kg of PCM (Phase Change Material) integrated in the supermarket’s shelves.

With this solution, a complex process is made simple. It easily manages the process of generating profits by the customer. It discovers and shows off the potential of improved facilities systematically through:

• Simulation models of the behaviour of installations based on experience, best practices and standards.

• Tools for measuring, monitoring, tracking and control with high level of automation. • Edge solutions that make the process of continuous improvement efficiency.

Our simulations show that we can save approximately between 40-60 % of energy on air conditioning system. This, coupled with the implementation of other smart strategies allow us to achieve annual savings of 20%

Physical area required for product or technology to operate

Do not need a large area to accommodate the necessary monitoring equipment, these are located in an outer box near the main electric panel.

The sensors are connected by a data bus two-wire, easy to install.

The energy storage system, is formed by PCM material plates of 5 cm thick, were placed in the back of the shelves and a structure adaptable to the upper linear if needed.

Installation process and timescales

The process for each store consists of three phases: The first phase of analysis of the characteristics of each particular store that will produce a theoretical model of behaviour and consumption baseline, a second phase appropriate measures improvement to each case, and a third phase of monitoring and control that will maintain and even increase the expected savings. In total, the first phase may take 2-3 weeks depending on the information that has already available.

The third phase will take place during the ESCO contract period and shall be accompanied issuing quarterly monitoring reports.

The installation of the basic improvement measures is done without interrupting the normal operation of the store, because all operations can be done without cutting the power. The installation of the control and monitoring system requires two visits, one of recognition and planning and other for installation. The installation usually takes 2-3 hours.

Resource requirements for operation

For this solution does not need any unusual item or any accessory security element. The system is modular and virtually plug & play. It consists basically of the control box is installed on the surface, from the various sensors that are installed depending on the needs of each store and finally the PCM panel system that is placed at the bottom of shelves.

Basically the solution consists of three subsystems: the computational model and the control


and monitoring system, the monitoring and control platform developed by Carlo Gavazzi, especially adapted for the supermarket sector and panels designed by ARQCOM using PCM materials marketed by DUPONT multinational

Product lifespan and maintenance requirements

The life of the product is very high, comparable to the estimated useful life of the supermarket.

Presentation of the proposal Impact

Our proposal contributes directly to energy efficiency, primarily by reducing the levels of some of the higher consumption: lighting and HVAC system to accumulate free or much cheaper energy over night depending on the time of year. In this way we reduce or even eliminate the need for heating and cooling demand during the hours of operation of the store.

This power reduction is directly reflected in a reduction of CO2 emissions directly proportional to the savings achieved, we estimate by 20% if performed complementary measures to optimize energy storage.

Accumulation measures interact synergistically with the control measures for reducing by 25% the maximum power used, enabling cost savings derived from adding the possibility of contracting less power. Therefore, the economic impact is estimated at an annual savings per store of around 25%, which allows us to propose a business model of shared savings, allowing the system implemented progressively by energetic service mechanism.

Innovativeness

Clearly, this proposal uses existing products and technologies combined with deep knowledge of the team working on the energetic performance of a supermarket or retail space.

The architecture team (ARQCOM) has over 20 years building supermarkets of all kinds and the efficiency and energy savings team (ACONDAQUA & aee) accumulated over 8 years of experience in audits energetic and projects to improve energy efficiency.

At present the monitoring and control techniques are very mature and widespread; being the differentiating element the criteria and expertise that allow us to interpret the information obtained and be done with it.

Regarding the thermal accumulation system energy by phase change materials, the technology is sufficiently developed for commercial implantation, but it is clearly innovative in the field and in the format of our proposal. Representation of some of the different elements of this

innovative solution.

Replicability

Since its initial conception, this proposal has been developed with clear criteria, their potential for replication and scaling up. It has taken into account the different types of construction that can take the stores, from low homes, factories and buildings adhoc. The system is flexible


enough to be able to incorporate each of the existing types.

Moreover, the modular design allows the same parts go implemented progressively, as they are to evaluate the results. In the case of thermal energy storage by PCM, the active system can be applied also in other sectors Consum distribution, for example in logistics warehouses without any problem.

With respect to its replication in other countries, we can say that the system is valid for any European Union country which uses artificial air conditioning, but it is estimated that the best results occur in stores that use a lot of air conditioning in summer.

Implementation feasibility

The viability of the application is very high since the team's knowledge and theoretical computer models developed to model the energy performance of the stores allow us to anticipate the best control strategies in each of the stores.

Our proposal includes a commitment to take investment risks, using the format of Energy Service Company (ESCO), so that the client does not need to worry more than to verify that indeed are saving on your energy bill each month of the year.

Another big advantage of our system is that the panels of thermal energy storage are very characteristic and the public will allow see the whole customer engagement with the environment in a clear and direct way.

Risks

Risk analysis yields very encouraging results, as the economic risk is very low to take ESCO investment costs. The degree of complexity of the system is not high and very low maintenance needs. The free energy we believe use that would facilitate greatly the social acceptance of customers, as well as moved a very powerful image of brand committed to the environment.

In this business model we share the savings by applying “the guaranteed savings mode”. In this case our company is the agent that guarantees the savings to the customer, the customer running the initial project financing

The following diagram explains the different scenarios of revenue for the company, along energy services contract.

Moreover, the solution does not cause any interference with the retail or the normal operation of the facility.

Proposal description Developing a new system of close loop geothermal heat pump system.

Our proposal, in order to take advantages of both systems, has been to create the Dynamic Closed Loop, a new concept intended to take energy from the earth in a cheap and easy way, without any issues related to the treatment of the water, because it remains always underground.

Further environmental safety is achieved by using a secondary water loop from the ground to the heat pump, keeping the refrigerating gas always inside the machine.

We want to develop a whole new equipment that works like a closed loop system, able to take the energy from the ground without the need to make several boreholes, hundreds of meters depth each one.

This new system can be used in new buildings and in existing ones, all of them can be optimized for an efficient heat pump operation. The application potential in this segment is nearly 100% and it is in this segment where the technology has reached the largest market penetration. By now, heat pumps are a standard in new residential buildings and they are increasingly used in industrial applications. Their application in the renovation segment provides a greater challenge: a simple like for like replacement (e.g. gas boilers with heat pump) will most likely result in a sub-optimal system. The energetic optimization of the building envelope is necessary to overcome this limitation. Technology development is also aiming at heat pumps that can efficiently provide output temperatures of 65°C to enlarge the possible field of efficient applications. As we can see, the target market of our proposal is one of the most suitable for this technology.

This new system is under patent process, just in the point to start the development stage.

1. Skipping the hurdles that some local regulations pose about taking water from the aquifers, using it to extract it the energy, and giving it back to the ground. As open loop systems have a little risk to contaminate waters with the system's fluids, hence the administration wields these concerns as a reason to impose some general restrictions.


2. We only used the water from the one aquifer, avoiding to communicate several of them, as it occurs when we make deep boreholes in closed loop system.

3. We improve the COP (Coefficient of Performance), making our system more efficient, because we obtain a better coupled ground temperature.

4. We can use this new technology in refurbishing processes for existing buildings, thanks to the minimal space requirements.

5. We put an intermediate safety loop (with just clean water circulating inside) between the ground source heat pump and the aquifer water, ensuring this one never will be contaminated.

6. We profit the Arquimedes principle to reduce the energy consumption of the water pump by the siphon effect generated: we don’t have to lift several tens of feet the pumped water, because it gets back to almost the same level when returned to the ground.

Other advantages

This technology can be used in new or existing buildings as described, which could bring many perks: higher energy efficiency, renewable energy usage, great potential

integration in existing facilities, outstanding performance, less administrative barriers with our technology, and a great potential to spread the knowledge in local markets.

The material in which is made, could be plastic o metallic one, but never a contaminant material.

This solution can be installed in any kind of building, because no big space is needed.

The installation is so quickly, we have to make a few drilling to take the energy from the ground.

We need water underground, we don't care the kind of the water; even marine water could be used.

This kind of technology has not any impact, instead, this renewable energy, that contribute to avoid to install others green energies like solar panels, forced to be installed by latest environmental regulations.

This new system is in progress to be patented, by the time the OEPM (Oficina Española de Patentes y Marcas) has emitted the concession of the protection.

This kind of technology can be used not only the HVAC system but others like refrigerators, etc.

1. Saving 80% of drilling and geoexchanger piping cost.

2. Boosting the performance, getting energy from the earth in a lower temperature.

3. Using less electric power to work.

4. We skip the need of taking out water from the ground. Thus, no water has to be wasted.

Proposal description Lighthermy is an innovative energy recovery system for LED lighting installations.

In all lighting systems, the energy consumed is split in heat energy and lighting energy. That’s why we get burnt if we touch a light bulb.

In the case of a light bulb, proportion is 95% to 5%. 95 % of the energy consumed is wasted in heat energy. In the case of LED based lighting systems, the overall consumption is much lower for the same lighting requirements, but the heat to light proportion is still up to 80% of heat to 20% light.

The LED based lighting systems have another relevant characteristic, heat energy is concentrated and can be retrieved and used bringing the whole system much more efficient.

Lighthermy retrieves up to 60% of the electrical consumption in applied energy usable for any kind of heating/cooling system.

In addition to the energy recovery, Lighthermy maintains LED lighting systems at a lower temperature, this increases LED efficiency by 10% and increases its durability by 30%.

Lighthermy products use the lighting industry standards. The current solution is based on Zhaga standard for LED lighting, although our interfaces can be adapted to any LED based lighting system.


Supermarkets are a high demanding area for lighting resources. An optimized lighting system can enhance the customer experience by providing the best intensity and color temperature to the products exposed.

In the case of Consum, we have defined a suitable project based in on a real store located in Granollers, Av Francesc Macià, 67-68. The store has around 800 m2 of usable surface, a height of 4 meters and regular architectural forms. The lighting system is based primarily on continuous strips of fluorescent lights , plus some specific typologies of chromatic light sources in some fresh products areas ( fishery, grocery, vegetables, …)

Lighthermy lighting designers have defined a draft of a lighting project based on LED lighting standards and Lighthermy solutions. After modeling the local lighting calculation software 3D , and implement the various light fixtures for general and specific sections, Lighthermy proposes a lighting installation that overcomes the lighting requirements of the store and achieves a high level of energy efficiency and savings.

Those savings can be divided in three steps:

Energy efficiency Step 1: From traditional to LED lighting

• Replacement of existing lighting fixtures by LED technology suitable for Lighthermy.

• This replacement provides a direct reduction in consumed watts of 55 %

• Increase of the user experience based on the specific lighting solutions existing in the market for specific sections like fishery or grocery.

Fig.3. Consum Isolux 3D view

Energy efficiency Step 2: From LED to Lighthermy

• The best LED technology, only transforms the 20 % of the energy consumed in lighting energy. The remaining 80% is lost.

• Lighthermy retrieves this thermal energy, so it can be reused or dissipated bringing the whole system more efficient. Lighthermy installation recovers up to 60 % of the electrical consumption.

• Lighthermy system can lower the working temperature of the LED light source. Efficiency and durability of a LED lighting system is totally dependent on its working conditions. The higher the working temperature is the lower efficiency and durability.


• Lighthermy parameterization allows to adapt the working conditions of the installation, we can choose to lower the working temperature of the LED light source or to maximize the thermal energy recovery.

• In the case of the Consum Store, we have assumed a 44% thermal energy retrievement for a working temperature below 40ºC. For each 100 W of consumption, 44 are reused for heating or cooling purposes. This efficiency can be improved up to 60% by increasing the working temperature.

• LED light source have a nominal working temperature around 60-70ºC. Working under 40ºC, we can have 10% more efficiency and a 30% more durability.

Energy efficiency Step 3: Thermal efficiency

Lighthermy System developes several interfaces in order to reuse the retrieved energy in the different heating and cooling systems in the market, such as traditional oil or water heaters, fancoil, HVAC or Hot Water Systems, ….

The system allows the application of the thermal energy retrieved to other thermal systems when needed in cold conditions and the dissipation of this heat outside the store in warmer conditions. In warmer conditions savings come from the reduction of cooling systems consumption.

Proposal description Supermarkets present very high energy consumptions due to the requirements of heating, refrigeration and HVAC systems. Furthermore, there is an intrinsically challenge given that the food has to be conserved at low temperatures and human comfort requires higher temperatures. The occupation is also variable throughout the day, and some aspects such as the opening of doors are quite common but must be considered as a big penalty. In addition, each supermarket has its own particularities, such as the global configuration (e.g. a ground floor in the city with air-conditioned spaces around the supermarket, an individual building outside the city, etc…), surface, existing HVAC systems, etc…

All of these boundary conditions have to be considered in any strategy to reduce the energy consumption, hereby leading to an equation which cannot be solved in a simple way. The proof is that supermarkets nowadays do not dispose of any simulation tools to reproduce the dynamic thermal behavior of the supermarkets and to quantify the potential benefits of many available technological solutions.

The potential technological solutions for supermarkets have been widely studied and demonstrated, particularly in recent literature from USA.

Many technological solutions (e.g. heat recovery) are well-known but in practice, supermarket holders need to know the pay-back time and energy savings of each solution, for any supermarket location and configuration. Consequently, this proposal aims to link the gap between the actual supermarkets and the existing technological energy saving solutions.


The key point from this proposal is to provide an accurate simulation tool to quantify the energy savings for each solution, depending on the specific configuration of the supermarket. The potential improvement of each solution is completely dependent on the supermarket configuration, as well as its location. These two points support the interest of developing a reliable simulation tool, particularly if it can reproduce the effect of each of the latter aspects. One of the best solutions is the use of a transient simulation software such as TRNSYS.

Potential improvements of supermarkets can be subdivided into passive or active solutions. Additionally, depending on the implementation level they can act on the operation strategies or directly on the design of a given component of the supermarket. For instance, adding heat or cold recovery in the ventilation systems will surely enhance the performance of supermarkets, but the improvement will not be the same in every supermarket. The improvement of the operation strategies is also very interesting since these solutions are very simple and can lead to a very low pay-back time. For instance, the different temperature set points and the on/off schedules of the HVAC systems can be redefined depending on the occupation, the electricity tariffs and the expected load for the day.

The aim of this project is to develop and validate a simulation tool in TRNSYS of a typical CONSUM supermarket. The best option is to choose a representative supermarket for which a maximum of technical data and monitoring results are available. The longer the experimental campaign, the better the accuracy of the model. The simulation tool would be developed progressively by means of a comparison with the measurements, and it would finally allow quantifying the different solutions for different supermarket configurations and locations.

A key issue is that any small improvement could lead to a great benefit on a national level, given the wide implantation of CONSUM supermarkets. Thus, the simulation tool developed for a typical supermarket can later on be extended as a global simulation tool, applicable for any supermarket.

The key features of the target model will be:

• Transient thermal model of the external envelope of the supermarket (insulation layers, properties of the glazing, etc…)

• Modelling of the different doors usage (main entrance, refrigerators, etc…) considering the main factors including a validation with measurements

• Modelling of the main heating and cooling equipment (HVAC systems, ovens)

• Modelling of the existing lighting system

• Independent validation of each sub-component

• Full validation for the entire model of the supermarket with experimental measurement data for at least one year of operation

• Analysis of energy savings solutions using the developed tool

This project will focus mainly on reducing the HVAC energy consumption, although basic, low pay-back solutions for lighting will also be addressed. Nevertheless, the latter have less margin for improvement given that many CONSUM supermarkets have already installed efficient lighting systems, even considering optimal schedules depending on the natural illumination and occupation level.

As detailed in the methodology section, once the model has been validated and adjusted, a parametric study will be carried out to quantify the potential energy savings of the list given here below, which are the known potential improvements of supermarkets, as previously studied in different countries such as USA.


Methodology

As shown in the next figure, on a first stage, a survey will be carried out among all of the published information on methods of lowering the energy consumption in supermarkets. The development of a dynamic model requires a significant data input from a typical CONSUM supermarket:

• Technical data on the building envelope

• Technical data on the heating and cooling equipment

• Schedules of each equipment and temperature set-points

• Experimental measured data during, if possible, an entire year at least.

The model will be developed progressively by means of a validation with the experimental data from CONSUM. Thus, a feedback is always necessary to improve the models and reproduce the real behavior more accurately.

After the model validation, the simulation tool will help to carry out a parametric study to quantify the potential energy savings of each solution in 3 different locations of Spain. The simulation tool will be handed to CONSUM and can be used in the future for any other location.

Another key point is to disseminate the results within the local press, or with brochures for CONSUM supermarkets, in order to promote the social awareness and to enhance the probability of technology transfer to other potential applications.

Impact

Night blinds or covers 0-20%1

Adding doors to display cases 0-20%1

Modify main entrance door 0-20%

1 Energy Savings Potential for Commercial Refrigeration Equipment


The previous table lists the technological solutions which will be addressed by means of the simulation tool. The potential savings which can be achieved, according to recent literature, are also given. The conclusion of the project will be to compare the cost savings, energy savings and pay-back duration of each solution, for 3 different locations in Spain.

Innovativeness

Most of the current CONSUM supermarkets are nowadays being monitored due to recent energy-efficiency measures. Nevertheless, the monitoring helps to compare the consumption of supermarkets between them, to compare the consumption with past years, but not to quantify which technological solution is the best for each supermarket.

Currently, there are no dynamic simulation tools being used to quantify the potential improvements of the available technological solutions. Although some tools are available (e.g. TRNSYS), this does not mean that they are specially orientated towards this application. Thus, the developed and validated tool would be completely new.

Replicability

One of the main advantages of the current proposal is the replicability of the service; indeed, the simulation tool can be used for any supermarket.

In order to simplify the usage of the simulation tool, a simple interface will be developed. Consequently, a user with no knowledge on TRNSYS can easily check, for any location, the effect of changes in the HVAC operation strategies, modifications in the type of glazings or insulation, the effect of heat recovery systems, etc…

Risks

In principle there is no particular risk derived from this project, given that the main work concerns the development of a software package and its validation with monitoring data from any of the currently monitored CONSUM supermarkets.

Concerning social acceptance, a key point is to promote the awareness among the consumers of the energy efficiency measures that are being implemented. The Institute for Energy Engineering, as a University member, can also disseminate the the results among the students, within the local press, and in general information brochures or posters to be placed in supermarkets.

This proposal does not interfere at all in retail activity, given that CONSUM already disposes of many supermarkets which are already monitored. The result of the project will be to provide the simulation tool to CONSUM, disseminate the results and to summarize the potential benefits of the assessed technologies for 3 different supermarket locations. The physical implementation of the solutions in a supermarket is out of scope in the current project proposal.

Proposal description The most effective and cheaper ways to reduce electricity costs are those related to a precise diagnosis and behavioral changes related to the energy use.

The aim of this proposal is to popularize the rational use of energy in the sense of sharing technology and make Consum workers play an active role. After all, technologies will have little effect if users cannot be convinced to use them.

The objective is to test an open source energy monitoring system for supermarkets and, once behavioral energy savings have been identified, to launch a 50/50 campaign. The 50/50 campaign aims to establish some energy reduction targets, and share the economic savings amongst the company and its workers. In a 50/50 methodology, everybody wins: workers have an incentive to save energy and facility managers have less energy costs and overall there are less CO2 emissions released to the planet.


Phase I: Open Source Energy monitoring

Materials and components:

– Open Energy Monitor system for monitoring the overall consumption of the installation and some specific areas as lighting, HVAC and freezers.

– Internet HUB to send information to the server. This module should be connected to the store LAN. If it is not available then a GPRS connector will be used instead.

– Humidity and Temperature Sensors

– Display to show consumptions and other data.

Physical area required for product or technology to operate:

– The system should be installed in the main electrical box and in the spaces where temperature and humidity should be monitored.

Installation process and timescales:

– Current Clamps are installed in the main electric box. There is no need to switch off any supply.

– Temperature probes can be easily installed anywhere using the Radio Frequency nodes.

Resource requirements for operation:

– No special requirements are needed.

Product lifespan and maintenance requirements:

– The average lifespan for these products is over 10 years except for the internet hub which can have around 5 years due to some memory read/write limitations. In this case just a SD card should be replaced.

Phase II: 50/50 campaign with workers

Materials and components

– Campaign material for Consum workers


– Mainly the area of one or two supermarkets to test the campaign and their workers

Installation process and timescales.

– Consum workers will be challenged to reach some specific targets on energy savings and the equivalent of half of this costs saved will have an effect on them via home efficient appliances or other material gifts or experiences related to energy or environment.

Product lifespan and maintenance requirements

– The campaign can be easily replicated in other supermarkets

The aim of this proposal is to popularize the rational use of energy in the sense of sharing technology and make Consum workers play an active role. After all, technologies will have little effect if users cannot be convinced to use them.

The objective is to test an open source energy monitoring system for supermarkets and, once behavioral energy savings have been identified, to launch a 50/50 campaign where everybody wins: workers have an incentive to save energy and facility managers have less energy costs and overall there are less CO2 emissions released to the planet.


Impact It is always complex to quantify energy savings when it refers to behavioral changes. However, some studies and experience give us the possibility to venture some value. In phase I of the proposal, open source energy monitoring will be installed in the selected venue. Our experience in energy monitoring has proved that only by having visual access to instant energy consumption, use of electricity can be reduced. If, added to this visual and understandable display, Consum workers have an incentive for reaching energy saving targets, overall energy saving could reach 10%. Considering the average 200.000kWh annual electricity consumption given in the Call, the pilot supermarket would be able to reduce by 20.000 kWh their annual electricity bill.

• Economic impact: With current electric tariffs 2.1A and 3.0 savings in consumption can be around 2000€/year. Applying 50/50 that means 1000€ for workers and 1000€ for the company. There are also potential savings adjusting the electric power of each installation.

• Environmental impact: 0.33 tCO2/MWh =6.6 tn CO22 • Social impact: To involve workers in energy saving could also generate a positive impact

on them as a team as they have an objective to reach together.

Innovativeness

This proposal is not about a new product but a combination of technology and communication. Concerning Phase I, there are many energy monitoring systems but the idea is to implement an open source one so all Consum supermarkets will be able to use it without paying licenses. Phase I is about 50/50 campaign where specific energy savings are targeted to Consum employees. This 50/50 win-win formula is not new and has been successfully trialed at different sectors such as schools. The innovative part of this idea is to extrapolate it to the supermarket sector, where workers are an important part of the business model.

Replicability

Once tested, this proposal is easily and inexpensively replicable in all Consum shops if wanted. The only costs associated to replicability are those related to energy monitoring system installation and workers training on energy aspects to reach savings targets. In fact, as the solution is based in open source software and open development technology, the know-how is fully shareable and, therefore, the solution can be replicated easily in many different stores. Moreover, the software is fully customizable and can be adapted to any store or new requirements.


This solution does not involve important changes in the general running of the shop. The key aspect for the success of this idea is to have a shop with a team of “Consum” motivated workers wanting to win individually and as a member of Consum.

Risks

Phase I: In this period the major risk will be determined by the wrong definition of the base-line consumption, referred to the period previous to the proposal actuation.

Phase II: The major complexity and risk in this phase is the one related to the willingness and motivation of Consum workers to participate in the challenge. Of course giving them the incentive will be positive to enroll them but it should also be enough to maintain them motivated during the whole period.

Proposal description The aim of the proposal is to provide a new integrated energy system as an upgrade of existing plants, enhancing their energy performance and producing the whole energy needed by the building through renewable energy sources. In this way it is possible to achieve the goal of a Zero Energy Building, as required by the European Directive 31/2010 UE and lead the Consum buildings to be carbon neutral. The name of the proposed concept is ConsumLess that means to convert the standard Consum store into a zero energy and environmental friendly building. As required from the contest the Consum new energy system can be easily applied to different typologies of store buildings and can be adapted in the size and configuration related to specific needs.

In detail, we propose a reorganization of existing system architecture, actually composed by


separated thermal machines which produce fluids at different temperatures (i.e. food refrigeration, HVAC for cooling, HVAC for heating, humidifier, steam, oven), into an integrated and efficient thermal energy production cycle that exploit the thermal gradient to enhance efficiency.

The concept is composed by the following main steps needed to improve efficiency and satisfy the reduced energy demands through renewable energy:

• installation of a small-scale (50 kWel, 100 kWth) biomass-fuelled trigeneration system (CHCP) as the main source of thermal energy and electricity; the system, composed by a gasifier, a reciprocating CHP engine and an absorption chiller, consumes 45 kg/h of wood chip and supplies directly electricity for lighting, oven/electric appliances and for HVAC electric subsystems; the thermal energy produced, together with the heat recovered from the oven though an heat exchanger, are directed to an absorption chiller to provide energy for refrigeration, cooling and heating. The Consumless system is able to obtain a running costs reduction of 81% related to actual costs: the residual cost is due to the wood chip to feed the CHCP system. The CHCP system is the component of the whole system which has the hugest dimensions: the installation needs additional space, approximately 20 m2 (e.g. rooftop, parking area), to place the system in case there is not enough space into the building technical rooms, mainly depending by the type of the building. Moreover a volume should be reserved to wood chip storage to have at least a week of reserve (i.e. 10 m3);

• interconnection of the single components/machines which produce cold and hot fluids through an hydraulic network and two thermal storages (cold and hot water storages) to recover and transfer unused heat; the storages are equipped with air heat exchangers to level the gap between hot and cold demand and production. In same circumstances, in fact, it is possible that energy needs are not equivalent and the differences must be dissipated somewhere; in this case the external source to be use as well/sink is air. In some particular circumstances it is possible to use some different resources, such as sea water, surface water, etc.

• installation of a main vapor-compression heat pump (250 kW) to balance and transfer the amount of energy for HVAC heating and cooling. The heat pump uses as source and sink the two storages that work as thermal buffers. The energy for food refrigeration and HVAC will be reduced due to the fact that the coefficient of performance (COP) and energy efficiency ratio (EER) of existing heat pumps will increase because it is a direct function of differential temperature between hot and cold parts of the refrigeration cycle; the closer the temperature are, the higher the coefficient will be. Moreover the heat comes from freezers and refrigerators will be recovered for heating.

• installation of two high-temperature heat pumps with carbon dioxide with the aim to produce thermal energy in the high-temperature section (e.g. humidifier and steam production);

• installation of a grid-connected photovoltaic system to cover the remaining electricity demand not covered by the CHCP system; the PV system is sized considering solar radiation of Valencia and the modules are installed on the flat roof of the store supported by simple structures to have a tilt of 30°. The photovoltaic modules technology is polycrystalline silicon with a nominal power of the single module of 230 Wp and the total PV plant power is 7 kWp. The PV plant is sized to be installed on the rooftop considering a major part of the roof surface used to accommodate thermal plants. The area of the PV plant is about 50-60 m2 that is a 5% of the total roof surface (assumed equal to 2000 m2).

• replacement of the 50% of the lights in the store commercial space with LEDs to reduce energy consumption, extend the lifespan and minimize O&M cost of the lighting system. The layout of GDO stores cannot usually exploit in a very efficient way the daylighting due to


depth of the spaces. The store is also described as equipped with overhangs to correctly shade transparent surfaces of the envelope thus the proposal is oriented in reducing artificial lighting demand. The lifespan of fluorescent lights is 8’000 h and the one of LED lamps is about 50’000 h so it is possible to increase the life of the single appliance of six times and then it is possible to deal with the replacement of the existing appliance on attrition basis with considerable running cost reduction for lighting.

• installation of a smart energy management system (SEMS) based on a predictive model to monitor and control thermal energy and electricity fluxes. This system is the managing tool which will decide how much energy will be provided by the CHCP system or by the vapor-compression heat pump, using as key marker the trend of various instantaneous power needs/consumptions (electrical and thermal), occupation profiles, weather forecasts, and all other information related with energy consumption. The SEMS is equipped with sensors that survey temperature (e.g. air and fluids), thermal loads, users presence, using profiles derived from predictive models. The implementation of this technology to control the whole ConsumLess energy system can reduce of a 20% the running costs.

The installation of above-described new components will be completed without interfering with the normal activity of the store, because it can be done through continuous and independent steps, during a working period of 4-6 weeks.

In addition just others few modifications will be applied to the existing systems, mainly related to HVAC heat exchangers, to be used with new temperature level and to the refurbishment of all refrigeration equipment to adopt new water/refrigerant heat exchangers instead of the existing air/refrigerant heat exchangers. Such intervention can be carried out gradually according to scheduled steps, minimizing the influence on the operation of different existing appliances.

The entire system doesn’t need any specific further resource requirement as long as it can operate with the existing low or medium voltage grid. Just it can be useful to adopt solution to avoid fire breakthrough in woodchips storage such as sprinkler or equivalent solutions.

The average expected lifespan of the entire system, in this power class, may be considered of at least 20 years and the yearly O&M cost for new configuration is estimated equal on average to 2% of the total cost of intervention.

The Consumless new energy system deals with the both fields of energy reduction required in the contest such as lighting and HVAC systems. However the Consumless concept wants to reach a higher energy goal and anticipate the European regulations. Thus the project is fitted on the entire energy demand due to Refrigeration, HVAC, Lighitng, Oven and Others energy consumption described for the standard Consum store.

The aim of the proposal is to make the Consum building Zero Energy, Zero Carbon Emissions and cheaper as much as possible. A Zero Energy Building can be represented by a pyramid of priority using envelope technology as the hugest basis level, efficient thermal plants and Smart automated system as second level and renewable energies source technologies applied to the building as the top level. The standard Consum store described shows that the building has rock wool insulation on the walls, although in the inside layer, and triple glazed windows. The roof is light and there are louvered protection systems and a depth overhang to shade the facades. As a consequence, the first choice of the project is to consider the envelope as efficient enough and focus the improvement of the whole building efficiency on technical systems, including solutions that exploit renewable energy sources.


The second step of analysis aimed in identifies the energy consumption distribution to understand the seasonal/yearly energy demands and the weight of each energy cost item; the largest item of energy consumption is refrigeration (56%) followed by lighting (16%) and HVAC (15%) of which 69% is due to the heating and 31% is due to the cooling. Other consumptions weigh for a 9% and the item oven is about 4%.

The contest requirements were focused on HVAC and lighting energy needs. However the main item is refrigeration and the proposed integrated system is definitely suitable for the thermal chain defined by the overview of the energy consumptions. The internal policy of Consum, which provides a saving of 25% on electricity compared to a conventional store and gained the Certificación A+ en la Memoria de Sostenibilidad in 20123, seems the most promising field in which to push a whole review of the technical systems architecture and the most ambitious even though achievable goal of zero energy buildings, to promote the Consum store as a comprehensive model of environmental friendliness, as stated in the Rules’ document.

The project on the thermal chain works out on the enhancement of thermal efficiency by reducing the temperature gap between the source and the sink used by equipment, which are usually split in a standalone architecture; according to such configuration each element of the plant produce hot and cold fluids at different thermal levels starting from the same outside temperature, while in the proposed strategy all subsystems are interconnected in a sort of local energy-network. This solution can significantly reduce energy consumption by maximizing exploitation of waste heat.

The proposed biomass CHCP system, the most expensive component of the ConsumLess new energy system, results by the promising possibility to cover the whole energy need producing both thermal and electric energy in collaboration with heat pumps and by the verification of the availability of this renewable source in the application context. In particular, in Spain biomass is obtained from a wide variety of plentiful sources (e.g. forest waste, olive stones, nutshells, etc.), which guarantees an uninterrupted and abundant supply anywhere in the country. Spain is particularly known for using biomass from forest waste, especially woody biomass, for heating; it is European leader in so-called “mountain forests”, the principal use of which is to produce wood for energy4.

Solar radiation is also a renewable source that can be fully exploited in Spain as the wide diffusion of photovoltaic plants demonstrates. The ConsumLess new energy system provides the remaining amount of electricity though a photovoltaic plant that can be sized as required in different type of buildings related to specific balance of energy and availability of surfaces. The replicability of the proposed strategy can be found in a main CHCP system to supply the thermal and electricity needs of the different type of buildings in which can be applied the CunsumLess concept and the photovoltaic plant acts as a buffer of energy production that can cover electricity needs higher than a 36% compared to that given for the Consum standard building, in the hypothesis of an equivalent available roof surface of 2000 m2 which 50% can be used for solar plants installation. The lighting consumption is reduced of about 30% replacing the half of the appliances (assuming to have standard-efficiency existing fluorescent lamps), with LEDs. LEDs are four times more expensive than fluorescent lamps however the lifespan is more than six times longer, reducing energy consumption and O&M costs. Considering a lifespan of the fluorescent lamp equal to 5’000 h we can assume that a lamp and a half has to be changed every day. Finally, the installation of a smart energy management system (SEMS) which controls the whole plants and lighting system in the commercial floor (2000 m2) reduces the running cost of an estimated 20% however this percentage can be enhanced in a specific design on the project.

Impact

The ConsumLess concept promotes a comprehensive energy efficiency strategy on building’s technical systems and provides the whole amount of energy by renewable energy sources, fully integrating existing technical solutions. The economical investment is estimated for the integration of new components included in the project such as:

• Biomass cogenerator;

• Absorption chiller;

• Vapor-compression heat pump and air exchangers;

• Thermal storages;

• Heat exchanger for the oven;

• Photovoltaic plant;

• LEDs for the lighting replacement;

• Smart energy management system.

The ConsumLess new energy system allows a reduction of the running costs equal to 80% (electricity cost is set to 0.15 €/kWh and woodchip cost equal to 46€/t), corresponding to a saving of 76.000€/year on the reference store. The estimated running cost reduction allows a simple payback time (SPT) of about 5 years, widely compatible with the lifespan of the Consum store. The use of renewable sources makes the ConsumLess system fully carbon neutral with a reduction of CO2 emissions of 100% that is approximately 200 tons CO2 avoided each year. The environmental impact is thus reduced to zero and the social benefit on public health is the maximum achievable.

Innovativeness

The ConsumLess system is innovative in its comprehensive approach on energy management and whole energy fluxes optimization and in its integrated structure of the plant's architecture. The realization of a technological components efficient network introducing thermal buffers allows enhancing energy performance and strongly reduces energy demand. The different technological systems used, characterized by a biomass CHCP system, vapor-compression heat pumps and a PV plant are not prototype technologies and they don’t imply uncertainty in the success of the operation. Nevertheless the proposed smart energy management system will use an innovative predictive algorithm, developed by our team, which will allow full integration and interaction among different subsystems, with an adaptive tune up avoiding thermal overrun in winter and under-run in summer. Also the gasifier is a standard product which has been modified to be fed with many kind of biomass. It is already been used with ethanol, wood chips, drained vegetable waste, as well as all kind of fossil combustible.

Replicability

The ConsumLess intervention strategy can be applied, with a specific resizing, in different store buildings. For example the possibility to extend the photovoltaic plant covering a higher fraction of the construction surfaces allows producing a greater part of the electricity need than in the Consum Standard store. It must be noted that a key factor is represented by the modularity of the system: the CHP engine will come in 50 kWe-100 kWt modules and each one is enough for 2000 m2 of store; as a consequence the heat pump will be sized to fulfill the thermal energy need not provided by the CHP unit. A key factor is the possibility to reuse all existing components related to refrigeration and heat production (HVAC units, compressor,


etc.) just replacing heat exchangers and therefore regardless of the specific type of appliance. The CHP system, in addition to wood chips, may use all available biomasses, such as olive oil production residuals or shell nuts.

Although different components of the system could need some resizing, the strategies and the main structure proposed can be assumed as suitable for a wide range of needs and functions. In different cases it can be appropriate introducing some energy efficiency measures related to the building envelope as a first step of energy demand reduction.


The proposed strategy can be applied without stop the daily operations of the building and no specific interference with the commercial activities is needed; the solution can thus be easily exported and implemented in other buildings. The process to feed the cogenerator is the single aspect that can require specific procedures to be adopted. The smart energy management system SEMS) based on predictive models allows to control loads and energy production simplifying and optimizing the energy flows. The photovoltaic system has not a huge power dimensions and it is grid connected; the national grid will work as a storage ensuring the electricity supply in all meteorological conditions.

Risks

The economical risk of the ConsumLess new energy system is mainly related to the change of wood chip cost. Other economical risks are not conceivable due to the use of technologies that are actually widely used in the built environment. The innovation related to the architecture of the system has no specific risk also if it is fundamental to carefully provide the optimized set-up, monitoring and control of the whole system. The installation of the technical systems and the lights replacement can be carried out during closing hours as usually done in stores and retails refurbishment. No different habits are required to customers/store managers and the zero environmental impact of the building will lead a strong advantage in reducing CO2 emissions.

Proposal description Smart-Setpoint (Smart-SP), a computer program to operate HVAC systems using weather predictions and predictive control.

Technology Description

One of the major energy-consuming systems of a building is the heating, ventilation and air conditioning (HVAC) system. More precisely, an HVAC system might waste more than 65% of the total electrical energy consumed by a building. The high-energy consumption of HVAC systems raises energy costs as well as environmental concerns.

While current HVAC systems start daily at a fixed time and fixed setpoint and stops when finishing an appointed schedule, our solution - Smart Setpoint (Smart-SP) - is a computer program, which is able to calculate optimal dynamic set-points for HVAC systems using weather forecasts and prediction models for different variables such as HVAC energy consumption, room temperature and room relative humidity (Fig.1).

Fig 1. Smart-SP Overall scheme


It combines the power of two different disciplines successfully applied to other different fields. By one hand, Smart-SP uses the methodology known as model predictive control; an advanced control technique widely used and tested in the control-engineering field in areas as chemical, refining, polymers, etc. Model predictive control uses dynamic models to predict the future dynamic behavior of the process under control.

On the other hand, Smart-SP always states the control problem as an optimization problem in which the energy consumption is always minimized maintaining within the specified limits room temperature and humidity. Therefore a powerful optimization technique is used - able to deal with this optimization problems and related with computational intelligence methods: the evolutionary algorithms (Fig. 2).

Using weather predictions, planned store occupancy and dynamic energy and climate models, Smart-SP for example, can anticipate to abrupt changes in weather - not unusual in the Mediterranean climate in recent years.

Fig 2. Smart-SP uses evolutionary algorithms to minimize energy consumption maintaining within the specified limits room temperature and humidity

Or it can manage holiday periods and weekends in a more efficient way, selecting the optimal switching on/off HVAC sequences and the better set-points from the viewpoint of energy minimization (e.g. widen the temperature band where no heating or cooling will occur – a cooling temperature of 25°C and a heating temperature of 18°C can reduce energy use by 20 per cent compared to a 20°C - 23°C control band).

Each hour, Smart-SP runs an optimization algorithm (based on computational intelligence methods and model predictive control), calculates the best values for the set-points of the HVAC systems and transmits this values to the Air Conditioning Control Unit.

Materials and Components

The hardware is the fulcrum of our solution although not part of this. An ideal architecture (Fig. 3) to deploy Smart-SP could be:

• Temperature and Relative humidity sensors: They will measure the inside store climate conditions.

• Power meters: They will measure the energy consumptions of the HVAC systems.

• Programmable Logic Controller (PLC): This device will be in charge of collect real-time data from sensors (climate and energy consumptions) and perform data processing preparing them to offer to the Smart-SP optimizer (e.g. performing each hour mean values each hour or integrating real-time consumptions)

• One computer runs the Smart-SP software. The optimizer receives processed real time data (temperature, humidity and energy consumptions) from the PLC through the network. Furthermore, weather forecasts are received through internet from weather services (e.g. AEMET, the Spanish agency for weather forecasting).

• Diverse material: network cable, network switch, etc.


Our solution needs a workstation in the store’s office with internet. The PLC and the power meters need enough space in the power control cabinet. Ethernet connection with this cabinet


will be needed from the workstation, as well as connection with the air conditioning control unit. Temperature and humidity sensors can be distributed by the store area high enough.

Installation process and timescales

Power meters, PLC, climate sensors and network cables will require installation by a qualified electrician under project specifications. Our team will be in charge of:

• Installation and configuration of the computer which will run Smart-SP software.

• Configuration and programming of the PLC.

• Programming and configuration of the communication network and fieldbus.

• Commissioning of the whole system.

Product lifespan and maintenance requirements.

Since the solution proposed is based on industrial components, it is very robust. The PLCs are very robust equipment they only need a battery change every 3- 4 years. Power meters and climate sensors only need a recalibration operation every 3-4 years too. Regarding the workstation, usual computer maintenance operations will be needed as OS and antivirus updates.

Impact Smart-SP product is designed specifically to deal with the problem of over air-conditioning in stores. Consequently the most direct and local climate impact of Smart-SP is to reduce spending on electricity bill – an immediate concern to the owner’s store. With a conservative estimate of 10% energy reduction (similar developments5 show 15% - 30%) on HVAC systems, Smart-SP proposal brings a saving of 1.5% of overall annual electricity bill (see Table 1). Further described in this section is the reduction in carbon dioxide and the social impact of Smart-SP.

Innovativeness Not currently exist in the market a product with similar characteristics, only a few prototypes based on research in other universities and research centers. Our solution is the result of many years researching in the two main topics that conforms Smart-SP: Model Predictive Control and Optimization. A particularized version of this solution is being applied under the framework of a “proof of concept” to a bio-refining process. In this application, the quantities of methanol recover in the unit, minimizing the steam consumption, are maximizing. Although the application is different our proposal has the same underling ideas and methods.

Undoubtedly, the Opticontrol project6 leaded by the ETH Zurich, is the only approach that shares the same ideas that Smart-SP. Besides academic partners, some big companies like Swiss Electric or Siemens, among others are supporting the project. OptiControl combines the newest developments from the fields of building technologies, numerical weather forecasting and control engineering. The project develops and tests novel, predictive control approaches plus corresponding software modules to be incorporated in commercial building automation systems.

Despite this, OptiControl is oriented to office buildings not supermarkets and it does not include optimization algorithms that use computational intelligence methods such as Genetic Algorithms or Differential Evolution.

Regarding market side, some commercial incursions which qualify as smart can be, among others, relay switches which shut off air conditioning or heating when a monitored door or

6 http://www.opticontrol.ethz.ch/index.html


window remains open for a period of time7, or a series of products more centered in the user side8 (web interfaces for scheduling, mobile apps for remote monitoring, etc.) than in the efficient operation side (these products do no change the way of control the HVAC systems)

Implementation Feasibility Once all the needed hardware is installed and commissioned, Smart-SP deployment comprises three well differentiate phases (Fig. 4):

Phase 1: Step-tests. Setpoints of the store HVAC system are shifted 2-3 Celsius degrees up and down. Then the climate conditions inside the store (temperature and humidity) and the energy consumptions are monitored. These raw data will be used to feed the algorithms that calculate the dynamic models.

Phase 2: Smart-SP parameterization. Based on dynamic models calculated, a set for controller parameters is chosen. Simulations are performed to test off-line the controller performance.

Phase 3: Smart-Sp start-up. The software is tested in real time. First, prediction mode is activated to check the validity of the predictions. Once secured this, the loop is closed and Smart-Sp is switched to fully automatic mode. As consequence, the HVAC set-points will be changed dynamically in an intelligent way minimizing the energy consumptions, maintaining within the specified limits room temperature and humidity.

Fig 3. Smart-SP Deployment plan

Phases 1 and 2 are the more consuming time tasks and they are part of consulting assignments. They must be replicated for each installation since the store characteristics (area, location, HVAC, etc.) will be different for each case. The disruption and disturbance with the store’s normal business will be small since only a small number of customers will see variations on comfort during Phase 1. If zero disturbances are wished, that phase can be developed during non-business hours.

Replicability Figure 3 shows a suitable framework for running the Smart-SP software. The hardware architecture that Smart-SP needs is very flexible since the software just needs to be feed with real time climate data, weather predictions and operation parameters. This data can come from different scenarios since every store facilities could be different (HVAC brand, type of building, network availability, data-loggers yet installed, etc.) and different budgets could be available (e.g. installation of wireless sensors). Therefore, various hardware modifications will be needed depending on current facilities Store.

As it was mentioned, the implementation of Smart-SP necessarily requires a phase of consulting. This feature gives to our solution a lot of flexibility since it could be adapted to

7 http://www.kadtronix.com/hsrs.htm 8 http://www.smarthvacproducts.com/product/env-hvac-control-system


different countries with different climate factors. Furthermore, the product can be adapted to other sectors in which the machinery or process operation influences the cost of the bill for electricity, natural gas, etc. (e.g. kilns, furnaces, refrigeration, pumps).

Risks We identified seven main risks for carrying out our proposal. Using a matrix, with likelihood and impact of risks, the level of each risk was calculated and color coded (with green being acceptable, yellow being unacceptable and red – not depicted – being highly unacceptable). Since the majority of the initial risk levels are in the unacceptable range we specified control measures to mitigate these risks. After implementing these measures the final risk levels were all found to be in an acceptable range. The risk descriptions, initial risk level calculations (likelihood x impact), control measures and final risk levels are depicted in the following table:

Proposal description The major savings come from a sustainable design

Nowadays, supermarkets are seeking strategies and innovation ideas for dealing with high competitiveness. Economy, sustainability and proper operation of machinery are the common goals. These objectives are sometimes in conflict. Nevertheless, we achieve these objectives in one solution.

The idea is to use the hot air that comes out of machines to make others machines work properly. Besides, it is desirable to capture the losses of refrigeration, ovens and HVAC in one single system and afterwards reuse it. Through this system we improve the energy efficiency, and consequently it reduces the cost and CO2 emissions. Additionally, other suggestions are given.

For this purpose, we make some changes in the supermarket design. The following figure shows the layout.


The design considers:

A. Reducing the use of artificial light by installing skylights strategically located and using reflective colors inside the building. We can increase natural light effects installing reflective panels to distribute the light inside the building. These panels must be located below the skylights. Furthermore, photovoltaic cells can be installed over the panel to switch on/off the LEDs bump. This means a reduction by 11% in the total energy consumption.

B. Installing solar panels at the overhang can save up to 2% of the energy. Further, this helps to heat water (see point 6).

C. “Green filter” making two processes at the same time.

a. Treatment of grey water using clay and gravel as a filter and plants as Nitrogen and Phosphorus eaters.

b. Cold point under the ground thanks to a potable water deposit nearby the plants. This water is use in the interchanger as detailed below. This means about 3.5% less consume in summer months.

D. Air curtains at entrances doors making virtual walls for cool/heat air can minimize losses.

E. The main proposal is an efficient space allocation. We placed the main machines (HVAC, oven and fridge) in a central room. Our aim is to capture the heat loss and connect it with the interchanger. Besides, oven is placed next to this room to increase its efficiency and use the heat to pre-heat the ovens. You can see bellow the seen from above of our design.


F. The main proposal is based on an interchanger air/water system. It connects the water from green filter and solar panel and the air from central room with HVAC system and radiant floor. Consequently, it reduces the air conditioning consumption. All this system (see next figure) results in saving of 7% of the energy in winter.

All this flow can be done by a hydraulic ram which has no energy consumption. The water loss is an inconvenient. However, this inconvenient can be transformed in a benefit if we use the water to garden the green zone.

In spite of refrigeration is not the point, we also think that it can improve the efficiency. One solution is to cover the fridges. Additionally, we propose a new concept of supermarket fridges. These fridges are based on reusing cold loss to its self-profit. The idea is to place the refrigeration room near the display fridge. Then, we can channel losses from insulating towards the display fridge and therefore, create an efficient process which reduces the CO2emissions and economical cost.

Implementation cost The cost of every device or idea has been assessed taking into account that the supermarket has been built without any device (only is built skylights and windows). If we compare the implementation cost with the profit, we can know the period for recovery of the investment.

The supermarket area is about 2000 m2, with approximately 4.5 m high and 48*32 m2 seen from above. We also install a green zone around the building except at the entrance for customers and trucks. The water deposit under the green zone can keep the temperature from 2 to 6 degrees below summer temperature or from 3 to 8 degrees above winter temperature. The water deposit should be designed properly to minimize the cleaning of the gravel in order to reduce the maintenance.

Now, we are able to describe the cost and life cycle of every device, following Less rules document.

It is said that the % consume reduction also brings us the % CO2 emissions reduced and % € we can save.

The following table summarizes the profit of our idea.

Next, we assess the year from which our investment starts to be profitable. The next figure evaluates the economic cost concerning initial investment, maintenance and save showing the result of the net profit. We can point out that the break-even point is after 4 years. With this project we create a new concept of supermarket based on a sustainable design. This supermarket achieves a profit in 5 years. We can also extract more conclusions from the table and the figure:

A. Solar panels are expensive, B. Refrigeration consumption is the highest one. Therefore, the most effective way to save

CO2 emissions is reducing it. C. HVAC system consumption in winter is high, so we reduce this energy by installing the

interchangers. D. Reducing the lighting consumption is the most profitable way to save money and CO2

emissions. In only 2 months we recuperate the cost of LEDs bumps investment. E. Solar panels are expensive but we use them in two ways, electrical and heat energy. So,

we can transform losses in benefits. We decide installing them over the overhang located at the entrance. That cost about 7000.00 € resulting in saving of 2 % of total energy. The more square meters of solar panels we installed, the more benefits are going to achieve.


Development of the winning ideas The projects “Optisinergy Solution” submitted by Mr. Ignacio Urcheguía Schözel and “AqH – Accumulation in quiet Hours” submitted by Mr. Jorge Aguilar Segura were the winning projects in the “Close to Market” category.

Both teams had to draft an “Implementation Plan” to define a pilot which could be implemented in a specific Consum supermarket with the support of a team of energy experts. The aim of the Plan was to assess the technical and financial viability of the solution proposed and determine the following stages in the programme as well as the funding to be allocated to each proposal.

The corresponding Implementation Plans were submitted in February 2014 and were then assessed by a team of experts (consultants) created for this purpose. The consultants’ opinion was announced in a technical and financial viability report, which was agreed and discussed in a meeting, during which it was decided that the “AqH” proposal would be given the support required to develop and implement the idea in the market. A pilot test of “Optisinergy” was dismissed but a small financial aid was given to help with the commercial promotion of the idea of the provision of ESCO services aimed at small businesses.

The following are the conclusions drawn from the assessment of the corresponding implementation plans:

Optisinergy Solution

This solution focuses on the design, the selection of the elements used, the calculation and measurement of energy consumption and the final financial analysis. The solution suggests the use of phase change materials (PCM) in the shelves of shops.

In order for the passive storage system to function optimally it must store energy during the night (off-peak hours) so that this energy can be used during the day (at peak and flat hours) and avoid the use of air conditioning.

In order for PCMs to store energy an exchange is required, whether by temperature difference or through flow. For areas with a small temperature gradient in summer, this temperature difference does not exist and so the air conditioning must be used at night. In areas where this temperature difference does exist, the ventilation system is enough to charge the PCMs.

In short, the Optisinergy project involves the introduction of a system which requires a large initial investment with a return period exceeding 3 years. From a technical point of view, the system requires a temperature difference which is difficult to find in a Mediterranean climate region; it also requires a very high surface area to a absorb heat with respect to the supermarket’s total surface area.


AqH – Accumulation in Quiet Hours

The AqH system implementation plan aims to reduce the energy consumption of the industrial refrigeration and air conditioning systems. The plan mainly focuses on improving the efficiency of wall units, display cabinets and work stations; and on the introduction of an ice accumulation system during off-peak hours which supplies cold glycol water to distributed chilling units.

The study focuses on the improvement of two of the systems: the installation of industrial refrigeration and the installation of air conditioning. To achieve this, the solutions suggested are to improve the efficiency of equipment that uses refrigeration (display cabinets, wall units, work stations and cold rooms), and to change the cooling and energy storage production/distribution system.

Improvement of equipment efficiency

• Refrigeration wall units and display cabinets: the suggestion is to change the current open equipment for closed versions, which work with glycol batteries at -7ºC which is obtained from the ice accumulation. The most important improvement is the suggestion of having doors to close the different units.

• Work stations: the suggestion is to have individual condensing units with scroll compressors, condensed with glycol at -7ºC, thus obtaining improved energy efficiency which can be condensed with air at 45ºC.

Suggestions are also made to improve cold and freezing rooms such as the use of a different technology for air conditioning equipment.

Improvement of the cooling and energy storage production/distribution system

The system suggested substitutes the currently used refrigeration installations for compressor-condenser units located next to the energy-consuming appliances. On one hand, the aim of this system is to increase the evaporation temperatures and thus reduce consumption, and on the other hand reduce the gas charge of the cooling unit.

The proposal suggests accumulating energy in ice balls during off-peak hours so that no extra energy is consumed during peak and flat hours.

The consulting team agrees on the quality of the AqH proposal and on supporting this idea due to its innovative character.

Saving on the electricity bill and improving energy efficiency in supermarkets through the synergistic use of air conditioning equipment to accumulate energy during the low-cost hours.

What led to the idea?

• The unstoppable increase of direct energy costs for food distribution chains due to the increase of electricity tariffs.

• The new European F-Gas regulation on the progressive removal of fluorinated gases.

• New Royal Decree RD 1642/2013 of 27 December on the taxes applied to fluorinated gases.

• A notable influence among large food chains and an interest in transmitting a green, ecological, sustainable image to their customers in line with saving the planet and contributing to climate change mitigation.

Objectives that encourage the development of the idea The design and development of a thermal energy distribution system to eliminate or mitigate the effects and causes listed in the previous section.

• Reduce the cost per Kw-h as much as possible

• Eliminate any gas leaks as much as possible to comply with the F-Gas regulations and reduce the effect of global warming

• Progressively eliminate fluorinated gases so as not to pay taxes for the use of these gases and contribute to mitigating climate change.


• Minimise the corresponding CO2 emissions by reducing the energy consumption of food distribution platforms

Developing the idea – AqH System

For every fundamental design idea, various innovative measures are developed that can be introduced jointly or separately. All of them must be adaptable to new technologies and refrigerants, as they are developed in the coming years.

1. Reduce the cost per Kw-h as much as possible

Designing a system that allows energy storage at times when the Kw-h cost is lower (off-peak hours) to use it during peak hours.

2. Eliminate any gas leaks as much as possible to comply with the F-Gas regulations and reduce the effect of global warming

Designing a range of equipment with a minimum refrigerant charge, where the gas is confined and can be assembled in a controlled testing and air-tight environment, while at the same time being susceptible to substitution of refrigerant type in-situ for other low-GWP refrigerants.

3. Progressively eliminate fluorinated gases so as not to pay taxes for the use of these gases and contribute to mitigating climate change

Using new low-GWP or zero-GWP refrigerants (CO2) in confined equipment and with heat transfer fluid distribution in order to use the surplus heat in other subsystems.

4. Minimise the corresponding CO2 emissions by reducing the energy consumption of food distribution platforms

Designing a range of equipment with a minimum refrigerant charge, where the gas is confined and can be assembled in a controlled testing and air-tight environment, while at the same time being susceptible to substitution of refrigerant type in-situ for other low-GWP refrigerants.

The importance of the Climate-KIC competition for AqH

Although the idea initially came from the need to introduce some changes to meet the new European requirements and regulations and to reduce the environmental impact of the high CO2 emissions due to the increase in energy consumption by food distribution platforms, the real implementation would not have been possible without the Climate-KIC competition.

The opportunity given by Climate-KIC for the AqH idea to be presented in a forum for entrepreneurs helped two of the most important companies in the industry of European refrigeration, Exkal and Tewis, support the project, with the strength that two such companies can provide, by offering their collaboration and their manufacturing, logistics and testing platforms in order to produce the necessary prototypes and their corresponding validations, with the main objective of developing the subsequent placing on the market and the standardisation to reach a global market.

Prototype development plan

The comprehensive AqH system consists of a set of elements that can be fully or gradually integrated into an installation. Although for the entire project to be viable, a planned development is required since its total integration depends exclusively on obtaining refrigerating receivers which are efficient enough to allow us to design a storage system for the required energy in a minimum space and with a low investment. In the current situation and with current receivers, the volume and investment required for energy storage would completely invalidate the project. Under these assumptions the development schedule for the different components is as follows:

1.- Development of a range of AqH adapted efficient showcases

2.- Development of AqH integrated equipment (CO2 and low-GWP)

3.- Development of AqH latent energy accumulation system

4.- Total integration of the AqH system and trials

5.- Standardisation and commercialisation process

Schedule for product development and placing it on the market The following schedule for the development of AqH has been planned so that the products with the greatest energy efficiency and sustainability potential are implemented first to then implement those which would provide the highest savings.

1. Efficient equipment range

The range of efficient refrigeration equipment made to operate with low-GWP refrigerants or, failing this, with Glycol from accumulation, is already on the market.

In the first stage, this new range of products is sold with a unit design which is condensed with Glycol, so that the accumulation solution can be introduced once it has been standardised.


First time introduced Intermarche France

2. CO2 and low-GWP units for AqH system

The principle behind the system is to confine the refrigerant, reduce energy demand of refrigerating receivers and accumulate latent energy during off-peak hours.

In order to do so, the development of a range of equipment which can carry out condensation using the fluid accumulated when the energy costs are lower, is essential in the initial stages.

This range of products has been developed in collaboration with Tewis Smart Systems. Mass production has already started as well as its commercialisation, both as individual units and as units to be included in efficient equipment.


3. Units to be included as part of efficient equipment

Production line at the Exkal plant where efficient equipment is being adapted with integrated units.

4. Aqh latent accumulation trial

Initial trials proved the technical viability of the accumulation system for its implementation; however some improvements are required such as the interchange temperature difference and the accumulation capacity of the eutectic fluid. We have therefore launched a research project, along with the company Exkal, to design and standardise a range of standard accumulators, and to design a new phase change energy accumulation fluid to optimise the energy and payback ratios as much as possible.

The laboratory trials are currently still under way and the measurements taken are promising. It was decided not to invest in certified measuring equipment and spend that amount on the design and development of the standard accumulator range.

The introduction of the current solution is complicated because it requires a previous study of each specific case and an engineering and installation analysis. The standardisation process is intended to have a range of accumulators for different powers, and for them to be modular so that the accumulation amount can be increased when required and easy to choose by the customer and the installer.

Once the range has been designed and the fluid developed has been obtained, obtaining a global patent will be considered.

Climate-KIC Climate-KIC is the EU's main climate innovation initiative. It is Europe's largest public-private innovation partnership focused on mitigating and adapting to climate change. Climate-KIC consists of companies, academic institutions and the public sector.

The organisation has its headquarters in London, UK, and leverages its centres across Europe to support start-up companies, to bring together partners on innovation projects and to educate students to bring about a connected, creative transformation of knowledge and ideas into products and services that help mitigate and adapt to climate change.

Climate-KIC currently has centres in France, Germany, The Netherlands, Switzerland, Denmark and the UK and is represented in the regions of Valencia, Central Hungary, Emilia Romagna, Lower Silesia, Hessen and the West Midlands.

Climate-KIC is one of the Knowledge and Innovation Communities (KICs) created in 2010 by the European Institute of Innovation and Technology (EIT), the EU body tasked with creating sustainable European growth while dealing with the global challenges of our time.

Climate Market Accelerator (CMA) Established by the Climate-KIC at the beginning of 2012, CMA funds projects which engage innovation buyers and help develop new markets for climate solutions. CMA projects focus on identifying, shaping and creating demand for new products and services.

Two objectives are at the core of the CMA programme and its project portfolio:

• to create simple mechanisms to accelerate engagement with innovation buyers, with the aim of ‘pulling through’ new climate innovations.

• to provide demand-side input and demand-side recipients for Climate-KIC activities from all three pillars - Education, Entrepreneurship and Innovation.

The CMA programme’s overall delivery objectives are achieved by funding projects that address innovation market barriers in specific sectoral or geographical areas. Each project is expected to deploy one or more of a range of demand-led innovation support measures, with the aim of engaging with innovation buyers with explicit innovation needs in a variety of climate adaptation and mitigation areas.

The impacts of CMA projects are measured through a range of core Climate-KIC KPIs:

• services and products launched

• new start-ups enabled

• policies and standards co-developed

• knowledge transfer agreements

In addition, CMA projects are targeted to secure a range of key deliverables including:

• demonstrators of products and services

• network facilitation (consultations with Climate-KIC experts sought from innovation buyers)


• investment influencing (new solution providers introduced to innovation buyers).

From the outset, the intention of the CMA programme has been to capture and assess the learning from the projects it funds so that demand-led innovation measures can be diffused and mainstreamed across other Climate-KIC initiatives. This toolkit is the first phase of achieving this objective and is designed to be updated as the CMA programme evolves.
