Residential heating accounts for almost one-fifth of Germany's final energy consumption. This report evaluates an extensive database of heating bills for buildings with two or more apartments, representing more than two-thirds of the total housing stock in Germany. Despite commitments to...

Das Beheizen von Wohnräumen macht fast ein Fünftel des Endenergieverbrauchs in Deutschland aus. Der vorliegende Bericht wertet einen umfangreichen Datenbestand von Heizenergieabrechnungen von Zwei- und Mehrfamilienhäusern in Deutschland aus - diese repräsentieren mehr als zwei Drittel des...

Despite a common EU directive on energy efficiency in residential buildings, levels of energy efficiency differ vastly across European countries. This article analyses these differences and investigates the effectiveness of different energy efficiency policies in place in those countries. We...

This report provides a detailed geographic analysis of two specific topics affecting the residential sector. First, we performed an analysis of new construction market trends using annual building permit data. We report summarized tables and national maps to help illustrate market conditions....

The German government aims at a climate-neutral building stock by 2050 to reach the goals defined in the Climate Action Plan 2050. Increasing the energy efficiency of existing buildings is therefore a high priority. For this purpose, investments of private homeowners will play a major role since...

Die Emissionsminderung im Gebäudesektor ist ein zentraler Baustein der deutschen Energie- und Klimapolitik. Jährlich wertet das DIW Berlin die Entwicklung des Heizenergiebedarfs in deutschen Wohngebäuden anhand eines umfangreichen Datenbestands aus. In diesem Jahr werden zudem die daraus...

Improving the energy efficiency of residential buildings is of paramount importance to reduce CO2 emissions and hence to achieve a climate-neutral building stock - the objective of the German government for 2045. Thereby, a focus on the existing building stock is needed, as regulations for new...

The German government has committed to reducing the primary energy demand of buildings by 80% by 2050. Achieving this reduction will require foremost efficiency improvements, with a first milestone of a 20% reduction in heat demand levels by 2020. Given that about 80% of today’s building stock...
