Climate Impact criteria

Page 16: Questions and Clarifications on the Application42twf1wvv8v1wnete1jdd6je-wpengine.netdna-ssl.com/wp... · 2019. 11. 15. · Clarifications on the Detailed Technical Application August

Questions related to the criteria• The Technical Review Committee (TRC) will undertake a thorough review and

assessment of the “Grid Electricity Consumption” excel template including the analysis and supporting documentation as well as information on the refrigerant(s) GWP value, if any refrigerant is used, to validate the achievement of the climate impact criteria.

• If no refrigerant is used or natural refrigerant is used, the GWP value will be considered as “zero” to evaluate the climate impact.

• To meet the prize criteria, the climate impact of the solution should be one-fifth (80% less) of the climate impact of the baseline AC unit.

Question: How will the Technical Review Committee assess the climate impact criteria based on the grid electricity consumption and refrigerant details provided in the application?

• If the cooling solution uses a refrigerant, its charge quantity in kilograms used will be analyzed by the TRC. If the TRC, at their sole discretion, believes that the quantity used is materially significant from the refrigerant charge used in the baseline AC unit, the GWP of the proposed refrigerant will be adjusted to reflect this higher charge.

• Weighted GWP of the proposed refrigerant = [GWP of proposed refrigerant X Quantity of proposed refrigerant in kg] / [Quantity of refrigerant in baseline AC unit in kg]

Question: What is meant by a materially significant refrigerant charge quantity? Does this affect the GWP value of the refrigerant used in the climate impact criteria?

• GWP of refrigerant of the combined solution = [GWP of refrigerant 1 x quantity of ref 1 (kg) / quantity of baseline ref. (kg) ]+ [GWP of refrigerant 2 x quantity of ref 2 (kg) / quantity of baseline ref. (kg) ] and so on……

Question: How is the refrigerant GWP value determined if the system has two or more refrigerant circuits?

Questions related to the criteria• Pre-cooling if completely automated using algorithms and sensors and built into

the cooling system is allowed. No manual intervention or remote modification should be included as part of the design. The TMY3 weather file may be used for understanding temperature profiles of New Delhi and design the logic / built-in devices for smart operation (including pre-cooling).

• The Technical Review Committee will assess the electricity consumption for pre-cooling the space for instances when the outdoor air temperature is below 20°C DBT and if it observed to be material, will consider it during adjudication.

Question: When daytime hourly cooling loads are larger than the cooling solution can handle, is ‘pre-cooling’ the space during night when outdoor air temperature is below 20°C DBT a permissible strategy?

• If a cooling solution is operated using a combination of grid electricity and an integrated solar PV or power generated from waste heat, only the “grid” electricityconsumption will be counted to determine the climate impact.

• If the grid electricity is completely offset by solar PV generation and there is excess power, no additional benefits will be taken into consideration, for example - selling the excess power back to the grid.

Question: How is the climate impact of a cooling solution assessed if it is integrated with a solar PV or energy storage technology or uses available waste heat to generate power?

• No preference is given to any method for determining the hourly grid electricity consumption of the cooling system. The participants may choose any method such as a mathematical model or an energy simulation software or any other sophisticated tool to determine the performance of their cooling solution.

• Any method used should be backed by sufficient calculations, assumptions and references to enable evaluation and adjudication by the Technical Review Committee.

Question: Is it mandatory to use an energy simulation software to determine the hourly grid electricity consumption?

Questions related to the criteria

• The “estimated bill of material cost” is the bill of material cost at a manufacturing scale of 100,000 units.

• The bill of material cost includes the cost of ü unit bill of materials, any external support components and consumables

• The total installed cost to consumer includes the bill of material cost and “other cost and margins” which includes overhead and labor costs, profits, dealer margins etc. The other costs and margins constitute approximately 60% of the total installed to consumer and is considered a fixed factor for the prize.

• The total installed cost to consumer excludes the installation related labor cost and taxes to the consumer.

Question: What is meant by the “estimated bill of material cost” and “total installed cost to consumer.” How are these different?

• The cost of manufacturing or procuring a component can be associated with either the test market i.e. India or any other market where it is manufactured.

• However, it is to be ensured that the component meets the quality standards of the test market i.e. India (at minimum) for this competition.

Question: Does the cost of manufacturing or procuring a component has to be for the Indian market or it can be another market?

Questions related to the criteria

• The maximum power demand criterion applies to power draw from the electricity grid only i.e. if the cooling technology has an integrated solar panel, or energy storage technology or uses available waste heat to generate power, that generation is not counted towards the 700 W limit.

Question: How is the power demand of a cooling solution assessed if it is integrated with a solar PV or energy storage technology or uses available waste heat to generate power?

• The power supply for a typical room air conditioner in the test market is 230V / 50 Hz.

• The participant can propose a cooling solutions with the standard voltage rating used in any other region (110 - 240 V). If the participant plans to further modify the input voltage to the cooling unit below 110 V or above 240 V, the internal components need to be incorporated in the prototype design and accordingly the cost and power loss of such components should be reflected in the application.

Question: What is the typical power supply in the test market for which the cooling solution is to be designed? Does the power demand include or exclude any transformer and converter related losses?

Hourly water usage of the proposed solution

Water Usage• Similar information was discussed in Slide 14 –

Climate Impact criteria.

• List of Assumptions and Calculations tab are same to other templates

• Participants should determine the water consumption while optimizing their cooling solution to meet the cooling load profile when the outdoor air temperature is above 20°C only.

• Participants should provide hourly water consumption of the cooling solution for purposes of evaluation.

• The daily fresh water consumption when averaged over the year should not exceed 14 liters.

• The maximum fresh water consumption for a day should not exceed 28 liters.

• The participant can add additional columns to the template to show the fresh water and condensate water (if recovered) consumption separately.

Questions related to the criteria

• We will consider the water (condensate) that is harvested and available for reuse. This harvested water will be subtracted from the total fresh water consumption on the day and accordingly the water criteria compliance will be evaluated.

• Any storage provision of condensate water must be part of the cooling solution itself as no separate provision for storage of water will be provided. The volumetric size and cost of such tank should be included under the Scalability and Affordability criteria respectively.

Question: Does the condensate recovered and reused account towards the water usage criteria? Can the cooling solution store the condensate generated on one day to offset the water consumption on another day?

• No, use of waste water is not allowed as part of the prize and participants are expected to not assume the waste water to operate their cooling solution.

• The reason is that the apartments or lab selected for testing will remain unoccupied during testing and will not generate wastewater that could be provided for utilization of the cooling solution and therefore we will not be able to validate the water consumption in subsequent stages of the prize.

Question: Can the cooling solution be designed assuming the availability of waste water in a household?

• An excel template “Cooling Capacity” is provided to show your analysis and results. The template has 3 input tabs – Cooling Capacity, List of Assumptions and Calculations

Cooling Capacity• Similar information was discussed in

Slide 14 – Climate Impact criteria.

• List of Assumptions and Calculations tab are same to other templates

• Cooling solutions performance and ability to maintain desired indoor conditions will not be evaluated when outdoor air temperature is below 20°C DBT.

• Cooling capacity data should be provided (similar to other templates) for all times when outdoor air temperatures are above 20°C DBT.

• Provide any unmet hours duration for which desired indoor conditions are not maintained below 27°C DBT and 60% RH when outdoor air temperatures are above 20°C DBT.

Questions related to the criteria• The cooling solution is expected to have a design cooling capacity of 1.5 TR at

standard outdoor conditions of 35°C DBT and 24°C WBT.

• While the solution will not be disqualified, if the design cooling capacity of the solution is less than 1.5 TR at standard conditions, it is likely to find it challenging to meet the cooling load profile of New Delhi, India over the full year and maintain the desired indoor conditions satisfactorily.

Question: Will the cooling solution be disqualified if it has a design cooling capacity of less than 1.5 TR?

• The cooling loads in a space depend on heat gains from internal loads and delayed sensible heat gains due to the thermal mass. The operation of the cooling system depends on these cooling loads and irrespective of the outdoor air temperature, the cooling system may be required to operate when these loads cause the indoor conditions to be greater than 27°C and 60%RH.

• There is “No Heating” included or required as part of the cooling solution.

Question: When outdoor air temperatures are above 20C but below 27C, does it mean that the solution needs to have a heating component to maintain indoor conditions?

• The unmet hours are determined when the cooling solution is not able to maintain the indoor conditions below 27°C DBT and / or 60% RH while meeting the given cooling loads when outdoor air temperatures are above 20°C.

• For the technical application, the total number of unmet hours allowed are up to 3.4% of annual hours i.e. 3.4% * 8760 = 298.

• Participants are expected to optimize the performance of their cooling solutions as long as the total number of unmet hours are less than the stated limit.

Question: How are the total number of unmet hours calculated?

• The total volumetric size of the cooling system will be calculated by assessing the maximum height, width and depth of the assembled unit(s) and any external component based on the technical drawings.

• There is no restriction on sizing of individual components as long as the total volumetric size of the system is less than 0.52 cubic meters.

Question: How is the total volumetric size of the cooling solution calculated? Is there any restriction on sizing of indoor or outdoor unit or any external component of the solution?

• No, standard piping connections required for components or collecting condensate will not be included in determining the total volumetric size of the cooling solution.

• If the piping volume is materially different from that required to install the baseline AC unit, it may be considered in the total volumetric size constraint of 0.52 cubic meters at the sole discretion of the Technical Review Committee.

Question: Is the piping volume included in assessment of the scalability criteria of the prize?

• Solar thermal energy can be utilized for operation of the cooling system as long as the solution can demonstrate to meet the total volumetric size and affordability criteria.

• No rooftop access will be allowed. The reason is that the prize is focused on identifying an alternate cooling solution with high efficiency and lower climate impact for mid to high-rise existing and new apartment buildings that would generally have no rooftop access.

Question: Can solar thermal energy be utilized for operation of the cooling solution?

Other common questions on prize criteria and application

Please note that this is only an example and the solution does not need to have the similar design as shown.

Other common questions on prize criteria and application• A structural modification to an existing apartment or home will be considered "major" if a

cooling solution requires material or significant changes to the envelope during installation as compared to the installation of the baseline AC unit.

• Participants are expected to provide the installation requirements of their cooling solution as part of the Scalability Criteria and the Technical Review Committee during their adjudication of the application will assess if the proposed modifications are major.

Question: In the Scalability Criteria, what structural modifications for installation of a cooling solution are considered to be “major”?

• If the operation of the cooling solution coincides with any heating requirement of a household such that the cooling solution has the potential to offset the energy use and/or capital cost of such a system, the Technical Review Committee will reflect the corresponding incremental climate impact or reduced capital costs in the evaluation of the solution.

• The maximum credit that the participants will be allowed for the energy savings will be the lower of the two – actual savings or 5% of the total annual energy consumption of baseline AC unit for this prize.

Question: Will credit be provided if the cooling solution reduces energy consumption or capital costs in an adjacent system through heat recovery for hot water generation?

• The cooling solutions are expected to be at a minimum of TRL 4 at the time of submitting the Detailed Technical Application. The Technical Review Committee will take into consideration the participants ability to submit two prototypes for testing in May 2020 when adjudicating the applications and selection of finalists.

• The participants should demonstrate in the application that they either are or have a route to quickly transition to the required technology readiness level i.e. TRL 6 in order to meet the requirement of development and production of two prototypes by May 2020.

Question: What happens if the Technology readiness level (TRL) of a cooling solution is below the scale of TRL 4?

Common questions on intellectual property (IP)

• No, you do not need to have obtained a patent to enter the Global Cooling Prize. However, all participants entering the prize will do so at their own risk and will be solely responsible for ensuring that they have taken appropriate steps to protect any IP that forms part of their application.

Question: Do I need to have obtained a patent for my technology in order to enter the Global Cooling Prize?

• Yes, you can enter the Prize if your design includes an already commercially available air conditioner. However, please be advised of a few points:1. In the Prize we are comparing complete cooling solutions. Therefore, in your bill of

materials, you must include the make and model of the commercially available air conditioner and its cost. In your written description, please be very clear about what your innovation is and what components of your design you purchased.

2. You may not be able to commercially exploit your technology if it is reliant on specific patented features or attributes of the air conditioner without obtaining permission from the patentee.

Question: My invention is added to an existing air conditioner to make it more efficient. Can I enter the Global Cooling Prize if my design includes an air conditioner I bought?

• To ensure no one has already patented your idea, you should review patent literature and non-patent literature. Patent office websites all over the world provide free access. You can use the websites’ search tools to search for any technology.

• Most countries have an absolute novelty requirement. If the technology you invented has been published in any language in any document anywhere in the world, it is unlikely that you will be able secure a patent if your invention is materially the same as a previously published technology.

Question: How do I make sure no one else has already patented my idea? And what if what I invent has already been invented and patented in another country?
