Already in 2021, an upward trend in the installation of heat pumps emerged, with a rising trend. This emerges from the new edition of the building report of the German Energy Agency.

In 2021, more than 170,000 heat pumps were sold for the first time, of which more than half were installed in existing buildings. In new buildings, heat pumps were installed 51 percent as the primary heating system. In existing buildings, gas-fired heating systems again dominated: Last year, 680,000 systems were newly installed or replaced, and renewable energies are used in one third of new heating systems. There are more than 30 million gas heating systems in the building stock. These numbers list the building report of the German energy agency GmbH (Dena) published on 8 November.

To the background: with the annually appearing building report the Dena lights up the status quo as well as trends and developments to climatic protection and lastingness in the German building sector. "With the Dena building report and its continuous monitoring of relevant developments in the building sector, we create an important data basis for politically and economically urgently needed decisions of the heat turnaround," emphasizes Andreas Kuhlmann, Chairman of the Dena Management Board.

According to the report, the building stock in Germany has continued to grow: at the beginning of 2022, there were 19.4 million residential buildings with 41 million residential units and approximately two million non-residential buildings. Also the floor space per person increased further: A person uses on the average 47.7 square meters (2020: 47.4 square meters).

In altogether five chapters the building report of the Dena dedicates itself to the ranges of topics building existence in Germany, heat generators, economy, energy consumption as well as climate and greenhouse gases. Furthermore, the Building Report compiles the subsidy programs of the Kreditanstalt für Wiederaufbau (KfW) and the Federal Office of Economics and Export Control (BAFA) that have been called up. For example, there was a record year in the now discontinued new residential building subsidy in 2021, with over 148,000 application commitments. 80 percent of the commitments were for the Efficient House 55 standard.
