Munich

The demonstration in Munich, Germany, constisted of two blocks of residential multi-storey buildings in the suburb of Sendling, built in 1954. The buildings were typical examples of the concrete brick constructions, built throughout Germany in the post-war era. The buildings are owned by the public housing company GWG München.

 

Retrofit concept

After about one year of construction the Munich demonstration project was completed and fully occupied in the summer of 2012. The building has been fully retrofitted including the replacement of the attic by an additional floor to create more rental space. Residents has been moved out during the renovation process.The building envelope is improved by an additional layer of prefabricated insulated timber elements (U-value 0.14 W/m²K) with modern highly insulated windows. The thermal bridges was eliminated by cutting off the cantilevering concrete balconies and replacing them with free standing balconies.
