Great climate thanks to highly flexible building services
The requirements imposed by the listed status of this property, which was built in 1939, and the complexity of the multi-use building, place high demands on the technical facilities. Together with AG Hallenstadion, we ensure the efficient operation of the energy supply systems and provide a highly flexible, energy-efficient and environmentally friendly energy solution. Our specialists are permanently on site and carry out fine adjustments and optimisations. This means that we can guarantee an optimal supply of heat, cooling, fresh air, electricity and water to the hall at all times.

Roof-mounted solar panels
The 2,340 solar modules cover around 4,000 m2 and generate an output of 725 kWp. This corresponds to an annual production of approx. 780 MWh. Thanks to their highly efficient monocrystalline structure, the solar modules are highly efficient, and their dark colour means that they blend perfectly into the roof. The solar energy generated is fed into the local energy service provider’s grid via seven inverters.
Biodiversity and the environment
The habitat on and around the stadium has been enriched with various environmental improvements. These include nesting sites for birds, newly created biotopes, green spaces and an in-house sewage treatment plant.

Groundwater as an energy source
For supply of power to this major urban development project and Lucerne, we consistently rely on renewable energies and a holistic energy solution. The heat pumps use groundwater, waste water and waste heat. This covers the majority of the energy requirements of the swissporarena, the sports buildings and the two high-rise residential buildings. The refrigerant used in the heat pumps is ammonia – it does not affect the depletion of the ozone layer or promote the greenhouse effect. This advanced energy concept has been honoured with the Minergie certificate by the canton of Lucerne.

Environmentally friendly energy solution for Triemli city hospital
Securing their energy supply is one of the most important operating requirements for hospitals. We provide electricity as well as heating and cooling for Triemli city hospital. Our environmentally friendly energy solution saves around 3,000 tonnes of CO₂ per year and supports the city of Zurich’s 2000-watt targets.
Our services include the planning, implementation, financing and operation of all heat generation and distribution systems. The project combines a wood-chip heating system and heat pumps, which draw their energy from geothermal heat and an intelligent heat recovery system from waste heat. Heating oil is used as a redundancy and to cover peak demand.
