This was a pioneering project: in 1998, Wagner & Co Solartechnik’s administration building was the first office building built according to the passive-house philosophy. This approach, which was ground-breaking at the time, was only decided upon during the planning phase, after the basis for the decision had been backed up by comprehensive thermal simulations. Despite the mixed reaction from architects, the building has proved to be a forerunner for a new generation of office buildings.
