Energy Efficiency

The heat consumption target of 50 kWh per sqm per year (which corresponds to an energy efficient house), is achieved through:

- Comprehensive thermal-insulation: walls (20cm polystyrene – EPS), attic (EPS 40cm) above the ground (10cm extruded polystyrene), foundations (15cm extruded polystyrene)
- Building envelope without thermal bridges
- Triple glazed windows, low-e and PVC 6 rooms
- Sealed construction, without air leaks
- Heat recovery ventilation
- Shading during summer time: the south facade is naturally shaded through the geometry of the house, while east and west shading is provided by roller shutters
