Refurbishment ML and FHZ ETH Zurich

Category: Windows and facades, News, Refurbishment
Year of construction: 2018 - 2019
Location: Zürich
Owner: ETH Zürich Immobilien Zürich
Architect: Itten + Brechbühl AG Zürich

With the refurbishment of the former machine laboratory (ML) and district heating power station (FHK), the ETH would like to use the buildings to their best advantage. As these buildings are national monuments, special attention must be paid to their maintenance and preservation. Therefore, only minor adjustments are permitted for both external façades.
The metal construction company Tuchschmid is installing a new façade, with high insulating capability, on the inside of the FHK-building. In addition, the FHK building will receive a superstructure with a post-and-beam construction and various skylights. The ML will be equipped with a new technical structure, the enclosure of which consists of thermally
insulated panels and a façade cladding.

The courtyard façade also included an aluminium cladding. A particularly big challenge was the planning and execution of the weather seal in and around the listed signage especially because it was not accessible from the outside. Tight spaces, limited road access as well as a tight timeline placed high demands on the construction schedule and the logistics.
