This building is the largest certified EnerPHit retrofitted building in the Passive House database. The 8897 m² space is a university building for the Faculty of Technical Sciences at the University of Innsbruck.
Originally built in 1968 and retrofitted in 2014, this building is a perfect example of a cost-effective retrofit, as many of the existing components were kept. The entire reinforced concrete supporting structure, consisting of ceilings and columns, as well as the reinforced concrete facade, were successfully preserved. By overhauling the remaining components (most importantly - the building envelope), the heating demand of the building was lowered by a factor of 8!
