Summary
The Techem Consumption Figures Study 2021 is a comprehensive report that evaluates energy and water consumption data from 2.1 million German apartments across approximately 176,000 buildings. The study highlights the urgent need for improved energy efficiency in residential properties, noting that a significant portion of heating systems are outdated and inefficient. It identifies the reliance on natural gas as a primary heating source, accounting for around 52 percent of residential heating, while emphasizing the importance of transitioning to renewable energy sources. The report discusses the potential of heat pumps in reducing dependency on fossil fuels and enhancing operational efficiency. It also presents data showing a 13 percent reduction in CO2 emissions related to heating, attributing this decrease to changes in the energy mix rather than consumption patterns. The study concludes with recommendations for improving energy efficiency and reducing emissions in both existing and new buildings, estimating a potential reduction of around 20 million metric tons of CO2e in the German multi-family housing sector.
