Active strategies

PV-system for Mechanical Ventilation, heat pump and lightsBore hole heat exchangerSolar thermal collectors

PV- system on the roof

3333

-Approx. 3700 kWh for mechanical Ventilation(dark grey) = 12 PV-modules- approx. 6600 kWh for heat pump(medium grey) = 21 PV-modules- 33 free PV-modules for lighting/electricity(light grey)

Bore hole heat exchanger

3434

Bore hole heat exchanger with heat pump- The heat pump provides 37°C hot water which can be used for heating purposes. 10additional heating devices are placed in the showers to heat up the water to around 60°C.- In the summer the cold water is used for offices area activation for cooling- 3 drillings deliver 15kW for heating
