Paper No 778 – Impact of the European Building Energy Requirements on the Heat Pump Market – 14th IEA Heat Pump Conference, Chicago, USA
To reach the climate targets set for 2040, it is necessary to increase the efficiency of the building stock and foster the electrification of the buildings’ heating system. In this framework, heat pumps will play an important role, in the process of phasing-out fossils. Nevertheless, to enable the efficient operation of a heat pump for heating purposes, low supply temperatures are required. This means that the building should be renovated (i.e. to reduce the heating demand) and the emission system should allow for low supply temperature operation. In this work, an overview of the development of energy policies in Europe is provided to show the requirements in terms of heating demand. In addition, the effect of the renovation deepness on the heating demand and heating load is shown using a reference multifamily building located in Potsdam (DE). For each renovation scenario, the room-wise heating load is calculated and the effect of the heating load reduction due to renovation in combination with different hypotheses for the sizing of the radiators on the design supply temperature and heat pump performances is described.
