In order to give architects and designers access to Global Warming Potential information for both interior and exterior building materials, Henning Larsen has released new open-source catalogs.

Henning Larsen has expanded its focus on data-driven design choices by releasing fresh research on building materials' carbon emissions that is intended especially for architects and designers.

Henning Larsen introduced Unboxing Carbon in 2021 as a carbon literacy course to give designers the fundamental knowledge they need to understand the environmental impact of building materials in response to the pressing need for climate action within the construction industry.

In 2022, the first Unboxing Carbon Catalog for exterior construction materials was released as a result of this initiative. Two extensive catalogs are now available from Unboxing Carbon: one for interior materials and an updated version for exterior materials.

Using information gathered from more than 1000 participants since the program's launch, the catalogs are the outcome of workshops held during the Unboxing Carbon course. 

The data, which is quality-controlled by Henning Larsen, comes from Environmental Product Declarations (EPDs) and includes easily readable metrics like Global Warming Potential (GWP). Based on carbon calculations, the catalogs give architects a useful tool to help them make better design decisions.

"These catalogs are our way of giving back to the industry - providing graphically appealing, easily readable, quality-controlled catalogs that professionals can use directly in their projects and in discussion with clients," said Martha Lewis, Head of Materials, Henning Larsen.

"The data is sourced from Environmental Product Declarations, organized by category, and broken down to an easily understandable unit, per square meter."

"Our aim is to keep the information accessible—no complex digital tools, BIM, or EPD interpretation skills required—just straightforward, visual graphics for immediate use in carbon-conscious design decisions," Lewis added.

Comprehensive information on materials like wallboards, system walls, interior cladding, tiles, countertops, and interior finishes can be found in the recently released Unboxing Carbon – Interior Material Catalog.

The most recent advancements in material manufacturing and environmental regulations are reflected in the expanded selection of materials in the updated exterior materials catalog, which now includes roofing, insulation, and updated data points. 

Now that the exterior and interior catalogs can be downloaded, the industry has a vital resource for promoting sustainability in design.

Henning Larsen won a competition to design a state-of-the-art concert hall in western Norway. In addition, the firm completed an experience centre for the acclaimed Swedish brands, Volvo Cars, and Volvo Group in a Swedish landscape with a striking "forest-like canopy".
