The building-related final energy consumption fell by around 20.2 % to 792 Terawatt hours between 2008 and 2024. This is equivalent to 35.2 % of the final energy consumption in Germany. Although over the years in question, residential and effective space have increased, energy consumption for room heating decreased. This is mainly the result of higher energy efficiency standards for new buildings and refurbished old buildings. Variation throughout the years is mainly due to differences in weather conditions over the years. The significant reduction in consumption of 13.6 % since 2021 is primarily due to efforts to save energy as a consequence of the Russian war of aggression against Ukraine. Compared to the previous year, consumption fell by 0.7 %.
In its 2010 Energy Concept, the Federal Government set the target of reducing heat requirements in buildings, defined as final energy consumption for heat, by 20 % by 2020. The target was not achieved. Consumption fell by only 10.4 %.
