Maturity stage TRL 7 - Prototype testing in the real world

The solution aims at providing a sustainable and reusable alternative to the traditional building industry. The patented solution is a sustainable and circular climate screen system that is used for building load-bearing external walls in e.g. residential housings. It consists of load-bearing modular frames made of wood, which help to ensure a healthy and stable indoor climate all year round, as well as operating savings of approx. 6% due to its innovative product design. A product design that, in addition to operational savings, also enables a total 22.7 m2 climate screen to be delivered within the framework of one EUR pallet. This feature means that external wall solutions for 4 houses of 140 square meters each can be delivered with just one truck delivery. The solution, therefore, contributes to CO2 reduction in both the choice of materials, the delivery, the operation, and the possibility of recycling the product as it is designed for disassembly and direct reuse.

The Environmental Benefits

  • 22.7 sqm of the solution can be flat-packed on one EUR pallet, making it 4-5 times more efficient to transport
  • The solution has a load bearing capacity of 194 kN per meter of wall, making it strong enough to implement in multi story housing
  • The Lego like building methodology of the solution makes it 5 times faster to build with compared to market alternatives
  • The solution has the capacity of storing up to 61kg of CO2.eq.m2 wall surface
  • The solution is mainly composed of renewable resources
  • The solution is a lightweight structure, meaning that slimmer concrete foundations are required to support the wall structure (less cement = less emissions)

The Financial Benefits

  • The solution is 5x faster to build with, saving up labour hours
  • As the solution is faster to build with, it cuts of time from a projects timeline, making it possible to generate revenue from the finished project faster
  • The solution is designed for disassembly, making is possible to dismantle and convert components into revenue after and ended period of use
