The renovation of this residential building locate in Munich was implemented in the framework of the FP7 funded E2Rebuild project (http://www.e2rebuild.eu/).
The residential multi-storey building in the suburb of Sendling, Munich (Germany), owned by the public housing company GWG München and made up of uniform standard concrete brick blocks, was built in the post-war decade of the 1950s. The building has been fully retrofitted, including the replacement of the attic by an additional floor to create more rental space, increasing the Net Dwelling Area to 3.323 m2 (originally 2.012 m2, + 65 %, phase 2 + 155 %).

A fundamental change in awareness and quality of communication plays a vital role in accomplishing the desired standards for the future. Tenants therefore need to be at the heart of the renovation of their building and the interests of the inhabitants have been a central concern in the planning stage. A high degree of prefabrication of construction elements and building envelope (TES Energy Facades) reduced the construction times and stress of all participants to a minimum. Finally, a tenants operation manual and recommendations (edited by the architects), simple and low maintenance technologies, efficient lighting system etc. contributed to an easy understanding of the living environment and low operating costs.
