PV- system on the roof
-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) 33
Bore hole heat exchanger Bore hole heat exchanger with heat pump
- The heat pump provides 37°C hot water which can be used for heating purposes. 10addition - In the summer the cold water is used for offices area activation for cooling - 3 drillings deliver 15kW for heating
