The Salzburg University of Applied Sciences' Kuchl Campus puts the school's focus on “timber, design and sustainability” into practice. The modern timber building, which was designed by Dietrich | Untertrifaller Architekten, is also an exemplary passive house. Timber construction is combined with a high-performance envelope and natural daylighting to bring the building's energy use down to less than 15 kWh/m² per year.
Completed in September of 2009, the Kuchl Campus extension is the first university building to conform to the passive house standard. Dietrich | Untertrifaller Architekten managed the design of the 4-story, 10,030 square meter building, which is surrounded by farmland. Three stories are located above ground with one below, and the south facade is glazed to take in the views and daylight. The south side also makes use of untreated silver fir slats that act as louvers to block direct light and limit heat gain.
The building is made of timber inside and outside. Supporting timber elements are clad with oiled birch-layered plywood, while non-supportive dividing walls are finished with drywall post-and-beam construction. The escape staircase is actually the only element not constructed out of wood. Built according to passive house standards, it consumes less than 15 kWh/m² of heating and cooling energy per year.
