- Use of groundwater as a heat source via well system
- Cold district heating network with three energy centres with heat pumps for supplying heating and cooling to buildings
- PV systems produce electricity on site as the basis for operating the heat pumps, supplying power to the buildings and providing charging current
- High system efficiency, resilience and self-sufficiency thanks to high PV self-consumption rates through sector coupling
