Visionary archtecture, sustainably

27 January 2020

Blending visionary architecture with sustainable building materials, this extension project will make Kunsthaus Zurich the largest art museum in Switzerland.


Building for (cultural) growth

The Zurich Kunsthaus art museum is a dynamic space for international exhibitions spanning from 13th century to the present. British star architect Sir David Chipperfield is designing the extension — and Holcim Switzerland is providing the building materials. Blending visionary architecture with sustainable building materials, the extension will make the Kunsthaus the largest art museum in Switzerland.

Building (with) sustainability

Between 2016 and 2018, Holcim Switzerland delivered 6,500 tons of cement to build the Kunsthaus extension. About 5,000 tons were made of our sustainable cement Modero 3B. Not only does this cement contain a low portion of clinker, which is responsible for most CO2 emissions associated with cement, but it also makes concrete surfaces brighter, well matching the project’s aesthetic requirements. What is more, Modero 3B works very well in the production of recycled concrete, which accounts for 95% of the overall concrete used for Zurich Kunsthaus.

Enabling low-carbon building

The majority of the CO2 emissions produced by clinker production are unavoidable, as they result from the chemical reaction that occurs when the raw material (limestone) calcinates into clinker in the kiln. We research, develop and market solutions that can replace the clinker in our final cement products with alternative mineral components such as pozzolan, slag or fly ash. A significant portion of these constituents come from waste or byproducts recovered from other industries.
