On the challenges by integration of heat pumps in existing buildings

The decarbonisation of the buildings sector is vital to deliver on the EU's 2030 and 2050 climate and energy objectives, given that buildings are responsible for 40% of total energy consumption and 36% of energy-related greenhouse gas emissions in the EU. In the Climate Target Plan 2030, the Commission has proposed to cut net greenhouse gas emissions in the EU by at least 55% by 2030 compared to 1990. The main scope of this paper is to depict problems and solutions in the process of shift from heat sources based on fossil fuels in buildings to heat pumps to achieve carbon neutral standard.
