The municipality of Wettingen set new standards with the full renovation of the Tägi. The expert team from the BKW Building Solutions network refurbished all of the electrical systems, reconfigured the electricity distribution and installed a photovoltaic system on the roof of the ice rink.
The modernised and expanded facility allows visitors to enjoy a unique experience. The Tägi now benefits from much more efficient and user-friendly operations. The renovation reduced the energy needed for heating by 60%. The new Tägi thus meets the Minergie standard in every respect, down to the smallest detail.
Our tasks
- Full refurbishment of the electrical installations
- Installation of the electricity distribution system for cooling the ice rinks as well as for treating and softening the water in the athletic hall
- Installation of technical systems (PA system, evacuation system, emergency lighting, clocks)
- Provision of power for 350 households thanks to the photovoltaic system on the roof of the ice rink
«We wanted to maintain the building’s structure while updating the infrastructure and technology to the latest standard in order to ensure the sustainability of the systems.»

Project description
The Tägi leisure, sport and event centre is an Aargau institution. More than just about any other location it is the social and athletic pulse of the canton. With a garden and indoor swimming pool, hall for games and sports, artificial ice rink, mini golf course, numerous options for culture, food, wellness and accommodation, as well as an exhibition centre, it attracts around 400,000 visitors a year. And it also sets a national standard: the Tägi is the largest facility of its type in Switzerland.
It was built in 1974 and over 40 years later, in 2020, the Tägi needed a full renovation as well as several extensions. The construction work included the refurbishment of the building’s technical systems as well as the building shell, the addition of a new roof to both ice rinks, and an expansion of the facilities to include another children’s area and a water slide. A key part of the CHF 46.5 million project was the optimisation of the energy balance and thus a reduction of Wettingen’s operating costs.
Minergie in the old building
BKW Building Solutions installed the high and low voltage systems and contributed its expertise in the field of renewable energies. The team of experts renewed the entire electrical installations and redesigned the power distribution. This included the refrigeration system for the two ice rinks and the water preparation and water softening systems for the indoor pool - everything had to be newly connected and rewired.
«The project to fully renovate the Tägi was one of the most challenging and wonderful tasks in the history of our company.»
Renewable energies for Wettingen
Geothermal heat pumps provide heat for the indoor facilities. When it comes to renewable energies, the photovoltaic system on the roof of the ice rink really stands out. The electricity produced is directed to the Elektrizitäts- und Wasserwerk Wettingen AG grid and is enough to power around 350 households. “This means we comply with the city’s requirements and make an important contribution to the optimisation of the CO2balance,” says Marco Baumann, CEO of Tägi AG.
