The German Heating and Housing Panel (GHHP): Survey data for the heating transition from 2021

Numerous measures have been taken in recent years to achieve climate protection targets in Germany's building sector. With the newly established Ariadne German Heating and Housing Panel (GHHP), the prerequisite for a well-founded evaluation of the effectiveness, distribution effects, and acceptance of climate policy measures in the heating sector has been created for the first time. Funded by the Federal Ministry of Education and Research (BMBF) as part of the Kopernikus project Ariadne, the GHHP is a series of annual surveys on the heating transition. It comprises around 15,000 participating households in Germany, 65% of which are owner-occupied households with the remaining 35% renters. In addition to eliciting detailed information on the building stock, existing heating systems, heating costs and the socio-economic characteristics of the households, the survey examines energy modernization measures that have already been carried out or are planned. The survey also records households' perception and acceptance of policy instruments in the building sector that are being discussed and have already been introduced. The first survey took place in 2021, with subsequent surveys to be continued annually until 2026.
