In line with the UN’s Sustainability Development Goal #7, WS Audiology’s Widex headquarters is a CO2-neutral solution. Opened in 2010, the building comprises a groundwater-based heating and cooling system, a 100-meter turbine, daylight-driven lighting, 14 electric car charging stations and 20,000 solar cells. Thus, we are able to produce 3.4 million kWh of energy per year and cut down on CO2 emissions by 70%.
