E2REBUILD Site Munich

The E2REBUILD demonstration in Munich, Germany consisted of two blocks of residential multi-storey buildings in the suburb of Sendling, built in 1954. The buildings, owned by the public housing company GWG München, represented uniform standard blocks built in the post-war decade of the 1950s to fulfil urgent housing needs, with three storeys and accessed by inner staircases. The resources were quite poor concerning material, construction and design, resulting in a lack of variability, technical facilities, daylight and comfort inside the buildings. Heating was provided before the refurbishment individually.

The Munich demonstration project was completed in a year 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 were moved out during the renovation process.

The demonstration in Munich (Germany) consisted 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. The energy demand has been estimated to drop after the retrofit from 220 kWh/m²/year to 20 kWh/m²/year.

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 have 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 were eliminated by cutting off the cantilevering concrete balconies and replacing them with free standing balconies.
