A hybrid ventilation system allows all ventilation forms: manual and mechanical, as well as local and automatic. A central exhaust air system with heat recovery helps to save heating energy. Heat generated by persons, solar irradiation and manual ventilation is sufficient to comfortably temper the building until winter time. A geothermal heat pump compensates for temperature variations in the winter and hot summers. Networking helps in saving energy: Mechanical ventilation and the heating/cooling function in a room are automatically switched off, as soon as a window is opened.
Networking is the conceptional core of the entire complex. In the suspended ceiling panels of the offices alone, several technologies are connected:
