Energy-efficient schools

Schools do not only provide a space for learning, but they themselves are buildings where experiences can be gained and as a result, they can influence the behaviour and attitudes of the students. It makes it all the more important that school buildings are exemplary; exemplary just as much in regard to user comfort as in regard to design and energy balance. In the research initiative Energy Efficient School (EnEff:Schule), a total of twelve demonstration projects, including seven refurbishments, were funded by the German Federal Ministry for Economic Affairs and Energy. They are to show which measures can be technically implemented, how much energy these measures save and how much they cost. At the same time, a sociological evaluation records the influences on user behaviour and the acceptance of the measures as well as the impact on learning comfort and daily school life. The vocational college is one of these example projects. The other types of school are a school building from the 1930s, an atrium building from the 1960s, two precast concrete schools plus a school and sports centre from the 1970s. They were refurbished as 3-litre-buildings or energy-plus buildings and have been partially rebuilt and extended. Different approaches were followed here.

The Uhland School in Stuttgart, a primary and technical secondary school from the 1950s, was also refurbished as an energy-plus school in the context of Eneff:Schule. High-quality insulation, in part with vacuum insulation panels, and combined with triple glazed windows reduced the heat loss via the building envelope. Ground-coupled heat pumps in combination with a low-temperature surface heating system heat the school. LED technology is used for the lighting. Photovoltaic modules on the roof, on the south facade and on ancillary buildings are sufficient to balance the electricity demand. During the heating period, decentralised ventilation units with heat recovery supply the classrooms with fresh air. In the summer, windows are used for ventilation. External louvres with daylight control protect the predominantly glazed outhern facade against too much solar irradiation. The building element temperature control is also used for cooling and is completed by a concept for night-time ventilation. In the first year of operation, the design achieved an electricity surplus of 42.5 MWh. Detailed monitoring is planned.
