Sports hall Liefering
With the triple sports hall in Liefering, the city of Salzburg has a pilot project regarding Smart City Standard. As a plus-energy building, it was awarded the Klimaaktiv Gold Standard. Over the course of the year, the new sports center produces more energy than it consumes itself and can thus also supply surrounding buildings.

With the triple sports hall in Liefering, the city of Salzburg has a pilot project regarding Smart City Standard. As a plus-energy building, it was awarded the Klimaaktiv Gold Standard. Over the course of the year, the new sports center produces more energy than it consumes itself and can thus also supply surrounding buildings.
The sports hall can be divided into three sectors and, with its dimensions of 45 m x 29.6 m and a clear height of 9 m, offers standards for many types of sport; the stands can accommodate around 300 visitors. In addition, there is a 90 m² movement room for gymnastics, yoga and dance. Office space for Salzburg's clubs and sports associations is located on the upper floor. Special attention is paid to sports for the people with disabilities: For wheelchair sports, a generous ramp leads from the foyer to the playing area.
The hall is powered and heated exclusively by solar energy and groundwater. Via a thermal solar system and the photovoltaic system, solar energy is used both for the generation of the necessary heating energy and for electricity generation. As a storage mass, the activated, 60 cm thick foundation slab ensures a constant room temperature at all times of the year. In addition, solar heat gains are achieved via the facade glazing. Due to the tightness of the building envelope and the efficient heat recovery of the ventilation systems, the sports hall does not require a conventional heating system. Additional cooling of the floor slab can be achieved in summer via a well system. (Text in shortened form: architects)
