Some 0.5 % of the energy used in the entire Main-Spessart Municipal Region goes to the School- and Sports Center in the town of Lohr am Main, which began operations in 1978 and consists of a college preparatory high school, a middle school, a three-part sports complex, and an indoor swimming pool. Now, through a planned integrated renovation process, the complex’s energy consumption and energy costs are to be substantially reduced. The goals are to create a CO₂-neutral energy supply and to approach the »passive house standard«.

For the implementation, three packages of measures will be at the forefront:

• With a highly heat-insulated building envelope which is largely thermally bridge-free, the end-consumption of energy will be reduced by approximately half.

• Multiple decentralized ventilation systems with heat recovery will also reduce the heat use, as will heat recovery from the swimming pool waste water.

• The required heating can largely be produced by a thermal heat pump system, which will use primarily, as its own energy, photovoltaic electricity. An ice-storage unit with around 1,250 m³ volume will function as a buffer, and will be used in the winter as a further source of heat and in the summer as a cold-storage system.

Energy Savings and Transferability

Through the exploitation of environmental heat and the absence of combustion processes, the emission of some 2,300 tons of CO₂ should be avoided annually. At the same time, optimal teaching and learning conditions, as well as sports opportunities, will be created.
