In the Henri Dunant housing development in Frankfurt-Sossenheim, GWH has carried out a large-scale project to supply energy to the neighborhood by constructing a local heating plant complete with a pipeline network and extensively retrofitting the buildings to improve energy efficiency. Modern heating systems now provide heat and hot water to the apartments in western Frankfurt with exceptional efficiency. GWH has been investing in the energy-efficient renovation of the Dunant housing development since 2021. Thanks to modern insulation, the buildings—which date back to the early 1960s—have largely been brought up to KfW standards ranging from 100 to 70, thereby significantly reducing the residential buildings’ energy consumption. At the same time, the heating system was converted to use renewable energy, and a pipeline network approximately 2,800 meters long was laid for this purpose. Since the new local heating plant on Dufourstraße went into operation, households have been reliably supplied with heat that is generated right on their doorstep and will contribute to long-term cost stability in light of current energy prices.
