HasleTre Wins the Prestigious "World's Most Sustainable Commercial Building 2024" at the Architizer A+Awards
Oslotre AS
HasleTre, designed by Oslotre Architects, is a demountable and reusable commercial building made of wood, located in Hasle, Oslo, Norway.
The building is constructed entirely from timber materials, both as the constructive, insulating, and protective materials, held together by innovative timber locks that replace the use of steel and aluminum. It is designed for reuse in a future circular value chain.
HasleTre achieved a 60% reduction in greenhouse gas emissions and an 80% reduction in steel usage compared to reference buildings. The building is classified as BREEAM Excellent and was constructed in record time. Today, HasleTre serves as the headquarters for the aid organization Save the Children
"Winning this award simultaneously with our demountable wooden buildings is a sign that the construction industry is changing," says a clearly proud Jørgen Tycho, Creative Director at Oslotre Architecture & Construction Technology. "We are moving towards more sustainable, circular, and biologically-based architecture, something Oslotre has been working towards for nearly 15 years. It's very gratifying to finally see the fruits of our efforts."
The steel used in the building is estimated to be reduced by 80% compared to the reference building. Multiconsult has calculated that HasleTre has 60% lower greenhouse gas emissions than the current industry standard (according to FutureBuilt Zero v01). 60% of all loose interior in the building is reused and upcycled. The building is designed for future reuse, and demountable materials can be traded on a secondary market. A significant amount of resources has been invested in the project to explore new solutions and methods. These have substantial transfer value to new projects.
