SOL4 (Mödling, Austria, 2005)

  • Type of project:
  • Integration type:

Austria’s biggest passive office building has a façade-integrated PV system. The grid-connected PV system is a ventilated cold façade. The heating energy requirement of the office building is so low (< 15 kWh/m²a) that, over the year, the PV system can supply it completely with the aid of a highly efficient heat pump.

The PV modules were mounted on aluminium rails with a four-point clamping system. The aluminium rails were simply screwed to the dense timber substructure.
