Title:
Abstract:	Die Sanierung eines gründerzeitlichen Wohngebäudes in Hamburg aus dem Jahre 1907 mit erhaltenswerter Fassade wurde im Rahmen des Forschungsvorhabens “Energetische Sanierung” (EnSan) des Bundesministeriums für Wirtschaft und Technologie gefördert und wissenschaftlich begleitet. Zwei baugleiche Gebäudehälften wurden mit unterschiedlichen energetischen Sanierungskonzepten und -standards (“EnSan-Standard” und “Hamburger Standard”) geplant und realisiert. Es wurden Konstruktionen einschließlich der dafür erforderlichen Einbauabläufe entwickelt. Die energetischen Zielgrößen sind erreicht worden. Der Endenergieverbrauch für Beheizung wurde um 80 % auf 32 kWh/m²a gesenkt. Der Primärenergieverbrauch beträgt gemittelt für beide Gebäudehälften ca. 95 kWh/m²a. Internal insulation of façades that are worth preserving. Example of a structural design project. The refurbishment of a residential buildings in Hamburg built in 1907 during the Wilhelminian era with a façade that was deemed worthy of preservation was funded as part of the research project “Energy-efficient refurbishment” (EnSan) by the German Federal Ministry of Economic Affairs and Technology, which also provided scientific backup. Two identical building parts were refurbished based on different energy-efficiency concepts and standards (“EnSan standard” and “Hamburg standard”). Structural components and associated installation procedures were developed. The energy target values were achieved. The heating energy end use was reduced by 80 % to 32 kWh/m2a. The average primary energy consumption for both building parts is approx. 95 kWh/m2a.
