Numerous measures have been taken in recent years to achieve climate protection targets in the 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. The GHHP is an annual series of surveys on the heating transition with around 15,000 participating households in Germany. The survey, carried out as part of the Kopernikus project Ariadne funded by the Federal Ministry of Education and Research (BMBF), is made up of around 65% owner-occupied households and 35% renters. In addition to detailed information on the building stock, existing heating systems and heating costs as well as the socio-economic characteristics of the households, the survey also 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 and the surveys are to be continued until 2026. This data description provides a brief overview of the first wave of the GHHP in 2021. It explains the process and methodology of data collection as well as the socio-economic characteristics of the sample. Information on how to access the data can be found in section 5; a codebook is included in the appendix.
