Umwelt Arena implements lighthouse project in Urdorf
The CO2-neutral development of the Umwelt Arena in Männedorf ZH won the Watt d'Or in 2021. The Umwelt Arena is now following up with a development in Urdorf. Three energy self-sufficient apartment buildings are to be built there.
The development of the Umwelt Arena in Männedorf received the Watt d'or 2021 from the Federal Office of Energy. The two multi-family houses in Männedorf can cover their energy needs with photovoltaic modules on the facades and roofs and two wind turbines. This means that your residents are exempt from electricity and heating costs up to an upper limit.
The Umwelt Arena is now following up with a new lighthouse project. In Urdorf, three more energy self-sufficient residential buildings are to be realized, is explained in an article on energeia + . The blog of the Federal Office of Energy will accompany the implementation of the project in a loose series of articles. In the first article, Walter Schmid, investor and initiator of the Umwelt Arena, explains the planned development.
As in Männedorf, the buildings in Urdorf will also produce their own energy, explains Schmid. “Photovoltaic systems are installed on the facade, on the flat roof or the entrance to the underground car park.” Excess energy produced in summer is to be fed into the gas network and withdrawn in winter. In order to convert the gas back into electricity and heat, a hybrid box will be installed in the basement of the building. The tenants of the residential buildings are to be exempted from electricity and heating costs up to an upper limit.
In the brochure for the project, the development in Urdorf is referred to as a “national future project”. Because the project should show "that it is worthwhile to build energy-efficiently and win everyone in the process," says the initiator Schmid. Männedorf has already shown that the idea works, that the larger project in Urdorf should "make it even cheaper, more economical". Because this is the only way to attract imitators.
