Solarwind

Solarwind is at the forefront of sustainable construction in Luxembourg, achieving triple environmental certification. 

The building envelope, solar orientation, materials and triple glazing were designed for energy efficiency. Heating and cooling is delivered via concrete core activation, coupled with heat pumps in the winter and passive cooling in the summer, optimising energy use and reducing maintenance costs. It is well ventilated (ID2), utilizing a dual heat exchanger and adiabatic cooling. The ventilation flows adapt automatically with air quality sensors that monitor the occupancy flow of the building. Other renewable energy sources used include urban wind turbines, solar photovoltaic & thermal, and biomass wood pellets for hot water production. Other features include rainwater harvesting for adiabatic cooling and toilet flushing, motion detectors and brightness sensors for lighting, a green roof facade and a ‘zero bin concept’.
