Berlin has the fewest energy-efficient apartments in the east

According to a recent analysis by Postbank’s 2025 Housing Atlas, which was compiled in collaboration with the Hamburg Institute of International Economics (HWWI), the supply of energy-efficient apartments in Berlin is below average for eastern Germany. To this end, Postbank and HWWI examined the available purchase offers with a designated energy efficiency rating of A+ (very good) to D (average) in German cities with more than 100,000 inhabitants. Berlin is not listed among the ten cities with the highest proportion of energy-efficient apartments; instead, eastern German cities dominate. With a share of 33.1 percent, Berlin is just above the average for the seven metropolitan areas, which is 32.3 percent, and the average for all major cities (31 percent). Jena takes first place with a share of 47.9 percent, followed by Cottbus with 43.7 percent, Chemnitz in eighth place with 40.1 percent, and Erfurt with 39.7 percent. In the ranking of price differences between energy-efficient and less energy-efficient apartments in metropolitan areas, Hamburg leads with an average price per square meter of €7,409 per energy-efficient square meter, which corresponds to a surcharge of €2,545 compared to less efficient spaces. Munich has a difference of €2,256, Frankfurt €2,237. Berlin ranks in the middle with a difference of €1,436.
