With a compact, highly insulated and airtight building envelope with triple-pane glazing, a ventilation system with heat recovery and the passive use of solar energy, Austria's first university building in passive house construction was built on the Kuchl campus. The three-storey timber construction is designed as a skeleton construction with beams and supports in a centre distance of 3.14 metres. Two panes of the solid staircase core and the closed end wall made of cross-laminated timber in the southeast serve as bracing. In the basement, the existing building was expanded in exposed concrete solid construction and houses the workshops and a workshop on the east side with a covered outdoor area. Due to fire protection, the escape staircase was also made of reinforced concrete.
In the north, the campus property borders on the area of the Holztechnikum Kuchl, in the south on the student dormitory. The central aisles of the existing building from 1995 lead into the new glazed passerelle, which connects to the transverse new building. The foyer on the ground floor leads to the drawing room, which is lit on both sides and can accommodate 200 people for events. On the upper floors, a wide, floor-to-ceiling glazed corridor provides access to the seminar rooms and the library.
The three above-ground floors seem to float above the site. They were combined in a frame-shaped building that shades the seminar rooms to the south by untreated silver fir slats and offers a view of the surrounding local mountains to the east and west. The building clearly declares itself to be a timber construction, both inside and out. Load-bearing wooden construction is clad with oiled birch plywood, if necessary, non-load-bearing partition walls are made of plasterboard stud construction. The Salzburg University of Applied Sciences thus does justice to the content of the scientific teaching 'Wood, Design and Sustainability' and uses the positive experiences of 400 students as multipliers.
