5. Page 5 Heat Pumps – Low Carbon Solutions for Re-Energising the EU Reduced demand in final energy demand by using renewable energy from air, water, ground (ambient heat) The renewable part (E renew ) is defined as the difference between the energy demand of the building (Q used ) and the final auxiliary energy used to operate the heat pump. E renew = Q used *(1 - 1 / Seasonal performance factor)

Page 7 Heat Pumps – Low Carbon Solutions for Re-Energising the EU Reduced GHG emissions by using renewable energy from air, water, ground (ambient heat) The GHG emission is defined by the efficiency of electricity production. When using electricity from entirely green sources, it could be as low as 0!

17. Page 17 Heat Pumps – Low Carbon Solutions for Re-Energising the EU Summary Heat pumps do contribute a triple dividend to all EU energy savings and GHG reduction goals. Improvements in the efficiency of the heat pump system and the efficiency of electricity production increase this potential. Improvements in the energy demand of buildings (as of EPBD implementation) improve the applicability of heat pump technology. Huge potential of heat pump technology in the renovation and commercial sector. 17
