    Abstract

    The SPF project defined a national hourly seasonal performance factor calculation method for air to air heat pumps, air to water heat pumps, ground source heat pumps and exhaust air heat pumps in co-operation with international Annex 39 work. The energy use of the Finnish building stock was estimated using standard building types further adapted to different decades: a detached house, an apartment building, an office building and a summer cottage. The energy use of these standard building types was calculated with different heat pump types leading to energy saving and renewable energy use of the heat pumps in different buildings. The current and future cumulative energy consumption of the building stock was modelled using the REMA model developed at VTT. The future effects of heat pumps on the energy use and emissions of the Finnish building stock were modelled comparing with the REMA model a conservative Business as Usual scenario with a Heat Pump scenario.
