Measures and Figures

SLF Winter

WSL has done a lot to keep its environmental impact as low as possible.

  • Wood chip heating: for over 15 years, our location in Birmensdorf is heated mainly CO2-neutral with wood chips
  • Production of solar power: at our sites Davos Dorf and on the Weissfluhjoch we generate year-round about 28'000 kWh eco-friendly solar power. In January 2016, our new solar roof in Birmensdorf went operational. It will generate an additional 50'000 kWh per year
  • Electricity purchases: since 2013, we purchase exclusively renewable electricity of the quality "naturstrom basic 2000". Composition: 95 percent hydropower ("nature-made basic"), 2.5 percent hydro ("nature made star"), 2.5 percent biomass, solar or wind energy ("nature made star")
  • Energetic renovation: our buildings are maintained constantly. After renovations in Davos in recent years the site Birmensdorf is currently brought up to the current insulation standard (Minergie-P Eco)
  • Optimization of operations: equipment and processes are continuously optimized. For example, the recent renovation of the cold cells in Birmensdorf saves about 100 MWh of electricity per year
