Power Tower
Austria
The Power Tower is the first high-rise office tower to attempt to meet the strict Passive House energy efficiency building standard. It was built to house the corporate headquarters of the Austrian utility company Energie AG in Linz, Austria. In accordance with the Passive House standard the building has no connection to the local district heating system, and requires no fossil fuel inputs to maintain a comfortable interior climate, resulting in much lower carbon dioxide emissions than comparable buildings.
