The German government aims to reduce the primary energy demand of buildings by 80% until 2050 and heating demand by 20% until 2020. Besides the need for additional efforts to achieve these targets, Germany has already implemented a set of policies and programmes to increase investments in thermal energy efficiency. This paper provides an overview of currently implemented German policies, specifically addressing two questions: A) What roles do different types of policies play in supporting energy efficiency in the residential building sector and how do they interact? B) In Germany, which policies fulfil these roles? How do they perform?
The report covers all main federal policies in Germany and reviews the current literature on the impact of the individual policy tools. It structures the review through a distinct approach which allows an easily accessible overview of the German policy mix. A comprehensive and detailed overview of Germany’s ambitious policy mix has so far not been conducted, yet is of interest to policy makers and researchers alike due to the increasing international focus on buildings’ energy efficiency both within and outside of the EU.
