Is a construction of heating systems based on regenerative energy (I.E. direct building heating with solar energy). The solar coverage of the annual heating energy amounts to > 88 %. When solarization is at its lowest and storage tanks are empty, a heat pump is used to provide supplementary heating. Climate control of the exhibition with environmental energy.
