Evaluation of the German "Federal Support for Efficient Buildings (BEG)" funding programme

Around 35 % of final energy consumption and around one third of greenhouse gas emissions in Germany are attributable to residential and non-residential buildings. The building sector is therefore of central importance for achieving the German government's energy and climate policy goals by 2050. In order to achieve the sector targets for 2030 and the goal of a nearly climate-neutral building stock in 2050, a considerable reduction of energy demand in the building sector is therefore necessary. In addition, the share of renewable energies in final energy consumption for heating and cooling has to be increased. The key to this is energy-efficient building refurbishment.

With the Federal Support for Efficient Buildings (BEG), the Federal Government supports both renovation efforts and the construction of new, energy-efficient buildings. The BEG combines the previous programmes in the areas of efficiency and renewable energies into a central, revised programme for residential and non-residential buildings. The BEG thus has an essential role to play in achieving the sector goals in the buildings sector. Is the BEG living up to the expectations placed in it?

The aim of the project is to evaluate the BEG as an overall programme. The main focus will be on whether the BEG has achieved the set goals and contributed to energy savings and the reduction of GHG emissions. In addition, the causal relationship between support (BEG) and target achievement (energy savings/GHG reductions) as well as the economic efficiency of the BEG will be examined. Finally, the project highlights where there is a need for action and where further development of the BEG is recommended.
