New Passive University Building in Upper Austria region
The Anton Bruckner Private University, was built according to passive house standards, meets high requirements in terms of acoustics and sound insulation, and also of energy efficiency.

In autumn 2015, the Anton Bruckner Private University opened its new passive building on the ground of the former Hagen Castel in Linz, Austria. During the World Sustainable Energy Days, O.Ö. Energiesparverband, together with its partners, organised a visit to this innovative building. With a total area of 8,600 m², the 3-storey building houses around 100 teaching and lecture rooms, 4 halls cumulating a capacity of 600 visitors and an open foyer, which connects all floors, for a total investment cost of about 43 million Euros. It also includes 2 underground levels and welcomes a total of 850 students and 220 teachers. It was planned and designed by the Architekturbuero 1 ZT. The university is under the financial responsibility of the region of Upper Austria.
The building was built following the passive house standards with a heat demand of 5 kWh/m²a. triple glazed windows were used. Its energy’s demand is supplied by the district heating of the city of Linz (fuelled by CHP plant, 40% with renewable energy), a 30kWp PV-system and 20m² of solar thermal panels.
One important element is the building’s architectural concept: the shape and facade were designed to look like a musical instrument. This is due to the University offering study programmes in music, dance and drama. The lamellae on the facade and the “fluss” (flow) allows for the building to keep cool in the summer and diffuse natural sunlight all day long. The wooden lamellae also reinforced concrete construction. This way, the University shows very well that the timber construction is also ideally suited for large objects with high geometric complexity and the highest thermal requirements.
