In Wil, a new residential and commercial development with bicycle parking is being built right next to the railway station. The heating and cooling energy is provided efficiently and in an environmentally friendly manner by a geothermal probe field regenerated with PVT collectors. The architectural firm S&H Architekten is responsible for the planning.
