Sustainability and energy efficiency- a major challenge

Global energy consumption has more

than doubled since 1970 – and an

additional increase of energy

consumption by almost 60% is

forecasted for year 2030*

CO2 emissions have increased from

18.3 bn tons in 1980 to 28.2 bn

tons in 2005 and forecast predicts

CO2 emissions to increase by more

than 50% until 2030 *

Excessive energy consumption and

scarce resources results in

escalated energy costs

Increased CO2 emissions leads to

accelerated climate change

Sustainability changes the building sector

The EU 20-20-20 Goal for year 2020

• reduce the greenhouse gas level by 20%

• reduce the energy consumption by 20%

• increase renewable in the energy mix by 20%

The Building sector *

• accounts for 40% of EU’s energy use and 36% of the CO2 emissions

• Represents a cost-effective savings potential of about 30%

• 90% of the environmental impact from a building is from its energy use (heating, cooling and lighting)

• Sustainability requirements will dramatically change the future building codes

__________________________________

* EU Energy Performance of Buildings Directive

(EPBD, 2002/91/EC)

The Energy Performance of Buildings Directive – EPBD

Requirements for Member States to specify and implement:

• An integrated methodology to rate the energy performance of Buildings

• Minimum energy performance standards for new and for existing buildings that undergo major renovation

• Energy performance certificates for buildings

• Regular inspections of heating and air-conditioning systems

• The 2011 EPBD recast stipulates:

― Member states to establish a plan to deliver very low energy homes

― All new buildings to be near zero by 2020

― Near zero targets to be defined for the complete existing building mass

• Energy source preference is given to

― Decentralised energy supply systems based on renewable energy

― Cogeneration

― District/block heating and cooling

― Heat pumps

What is Uponor’s contribution?

Sustainable solutions for residential buildings

People expecta comfortable living environment indoor

• People spend about 90 % of their lifetime indoor *)

• Indoor environmental quality has to be healthy, comfortable and stimulating

• The challenge is to provide a healthy and stimulating indoor environment while at the same time optimising energy use and introduce renewable energy sources

Study on energy saving of

Radiant System in a residential building

Three emitter systems :

-Radiant floor = 35/28 supply/return temp – On/off Contro (PI)

-Radiators with Heat pump = 50/35 supply/return temp – wall mounted PI control

-Radiator with Boiler, 77/55 supply/return temp – wall mounted PI control

Conclusion for Residential buildings

The moderate temperature of the water (18 30°C ) and the large

radiant surfaces, ensuring maximum comfort and using minimal energy,

makes Uponor radiant heating and cooling system particularly suitable

to increase the efficiency of the heat source, such as a condensing

boiler or heat pump and enables the use of renewable energy and

sources of free cooling.

Several independent studies have proven that radiant heating and

cooling systems provide superior comfort and typically less primary

energy1.

Saving are typically 25% compared to radiators and

traditional air conditioning system if the total

summer and winter season is considered2.

Up to 24% CO2 savings per year of a compared to

standard HVAC systems2

More savings with the innovative Uponor DEM control system

Energy saving through Dynamic Energy Management

• Active energy need calculated per zone

• No need for manual loop balancing

• Results system working on an optimal energy consumption level, which is lower than with standard on/off systems

• Supply diagnostics to show if the system is not working on optimal level, especially relevant when using heat pump

• Improved support for cooling

• Additional energy savings up to 5-10%

Sustainable solutions for Commercial Buildings

Radiant System in a commercial building

Creating a comfortable environment in commercial structures is a critical design consideration. Comfortable employees are more productive, and comfortable customersare more relaxed, contributing to the success of a business.

The radiant system works with water temperatures close to the ambient temperature, which allows low-exergy design, resulting in reduced primary energy consumption..

Uponor sustainable solutions for commercial buildings

Uponor offer a extensive range of installation possibility ,to meet the target to use at

its maximum the radiant energy saving potential in commercial building

Source : analysis of energy demand of an office west oriented - LEDA - 2010

The aim of study is to evaluate the average energy consumption of a typical year. A building simulation with the software DIGITHON has been carried out.

In the Barcellona case the overall energy saving ( Winter/Summer) of Uponor radaint ceiling is – 31 % compared to fan coils

Study on energy saving of

Radiant System in a commercial building

Primary energy use for heating, cooling and ventilation, resulting from an EnergyPlus simulation of a typical office building (511m2), operated in different European locations. The building design fulfill national energy regulations.

All systems works with condensing gas boilers and air cooled chillers.The radiant ceiling system has in addition the possibility of free cooling through groundwater (18°C)
