KALZIP – „Museum Lausanne“
25,000 m² of Culture
In 2022, a futuristic building complex named Plateforme 10 was opened in the Swiss city of Lausanne, merging two museums under one roof. It houses the Elysée Photo Museum and the mudac, a Museum of Design and Contemporary Art. This newly created art district provides visitors of all generations with over 25,000 m² to explore the diversity and various types of art in the fields of visual arts, photography, and design. The structure, designed by Portuguese architect Aires Mateus, combines geometric shapes with carefully selected surface materials to provide a futuristic look. The building has a light corridor that serves as the entrance to both museums, as well as a reception area, a bookshop and a cafeteria
At first glance futuristic, sustainable at second
The building’s exterior facade might appear plain at first sight, but hidden behind the walls is a unique shed roof made of aluminium profile panels from Kalzip. The roof with its striking jagged profiles is only visible from an aerial view or from the surrounding residential buildings. Despite its unconventional appearance, it fulfils a functional purpose, as the south-facing sloping surfaces house photovoltaic modules on the standing seam profiles, which supply the museums with sustainable electricity and ensure an excellent energy balance. To bring daylight into the mudac on the first floor, windows were added to the north side of the aluminium shed roofs. Upon entering the exhibition space, visitors are greeted with an open room atmosphere, highlighting the geometric design language of the interior architecture.
Waterproof planning on the model.
The complex roof structure with its horizontal and inclined surfaces required detailed planning. Kalzip’s standard roof system was modified to accommodate the integration of windows. Instead of the typical crimping of the standing seam profiles at the seams, the profiled sheets with a width of 65/500 were welded at the bending point, ensuring a waterproof, tight transition between the horizontal and inclined roof surfaces. In Switzerland, aluminium is less frequently used for roofs due to its different welding properties compared to copper or zinc. However, the processing characteristics of Kalzip’s aluminium profiled sheets were ideal for the project requirements, which demanded a column-free roof structure with pre-stressed steel beams. To address the challenges of mitre cutting and welding the trapezoidal profile panels, a model was first created to fine-tune the details with the owners and architects.
A lightweight meeting all requirements.
To minimize welding work on the construction site, a specialized contractor with expertise in the now-rare welding of aluminium seams prefabricated most components in a nearby workshop. These pre-made elements were then delivered to the construction site and installed. This allowed the final roof system, consisting of Kalzip’s standard roof components, including trapezoidal steel profiles, composite clips to fix the profiled sheets and provide insulation space, and the prefabricated aluminium profiled panels, to be fitted efficiently and with ease of installation. The entire roof system, including the trapezoidal sheets, insulation, and aluminium panels, weighs only about 13 kilograms per square meter, and is significantly lighter than a traditional flat roof which would weigh around 70 kilograms per square meter. The aluminium roof panels were coated with AluPlusPatina Eloxal Natur to meet the city’s requirement not to dazzle residents with potential reflections from the aluminium roof.
As a result, the new cultural district in Lausanne not only impresses visitors with its futuristic design but also, like all Kalzip projects, stands out for its functionality, sustainability, and maintenance-free durability.
Considered with care. KALZIP.
