The tram depot in the Oerlikon district of Zürich dates back to the 1930s. The outdated complex had long since failed to meet regulatory and operational requirements. And so the depot, which is under a historical preservation order, has been made energy-efficient and optimised for operation. The architects at Ernst & Humbel chose steel Janisol HI forward-mounted windows and Janisol HI windows for the insulation. The windows combine slimline frame profiles with innovative technology for the highest thermal break. With their triple insulating glass, they achieve outstanding thermal insulation values.

Outdoor cleaning system under cover

To be able to clean all of the trams in the future, regardless of the weather outside, the outdoor washing facility was enclosed as part of the refurbishment. This is where the Schüco AWS 65 aluminium window system can be used. The system is Cradle to Cradle-certified and has other benefits such as good thermal insulation, narrow face widths and concealed fittings.
