Umwelt Arena presents "Building 2050 Urdorf".
With the "Building 2050 Urdorf" project, the Umwelt Arena Schweiz is presenting a power house without electricity and heating costs for tenants. It will be presented in the new “Building 2050” exhibition in the Environmental Arena from mid-July.
The Swiss environmental arena has presented its latest future energy policy project, “ Building 2050 ”. According to the press release , the pioneering project in Urdorf shows how, thanks to the use of the latest building technology, residential developments can already become a CO2-neutral power plant in which tenants can live within their own energy budgets without electricity and heating costs.
The Umwelt Arena is presenting all of these innovations in the new exhibition “Bauen 2050” in Spreitbach from mid-July 2022 with a construction documentary and interactive elements relating to modern construction.
The pilot project in Urdorf is referred to as a “power house”. The building by René Schmid Architekten AG Zurich shows that surplus solar energy from the summer can be used to produce renewable, non-fossil gas for the winter using photovoltaic systems on the roof and facade. There is also a wind-solar small power station. The facade and roof insulation protects the house against cold and heat. In midsummer, excess heat can be withdrawn from the apartments and used to heat the water. The rest is stored in the ground via the geothermal probes.
The excess electricity from the summer is used to produce hydrogen in a power-to-gas plant. It is temporarily stored in the existing gas network for the winter.
The house in Urdorf shows the residents their daily current consumption level in order to control their personal energy budget. There are sun blinds that can be controlled depending on the weather, energy-efficient, networked household appliances of the highest efficiency class and showers with heat recovery as well as CO2-controlled comfort ventilation. Even when using the lift, the braking energy produces electricity.
