Co-founder Marten at a building conference.
We are running out of resources, 50% is used by construction and this is causing big damage to our earth.
Nowadays, most buildings are optimized for low cost on a short term. We believe optimization should be for long-term sustainability, and cost. Therefore, our vision is to make sustainable buildings the obvious choice for everyone. Our easy-to-use tool makes complex design choices simple to understand for everyone, especially decision makers who can be investors, politicians, project-developers. Our reports generated, acts as a design guide for others to build more environmentally and financially sustainable buildings.
