We guarantee the quality of our Green Structures. Renewbuilding works with production partners who are KOMO certified. KOMO stands for objectively determined quality in construction and infrastructure. In the interest of our planet, it is only logical that we only use sustainably produced wood from certified forests. Our partners who produce the circular hulls do so under FSC, PEFC or STIP certificates. These certifications show that we take sustainable and social forestry management, business and purchasing seriously.


We go beyond what the Buildings Decree prescribes. We believe that a good process description and quality control in and outside the factory are important. Thus, together with our partners, we continuously work on process optimisation.

Finally, we emphasise that the application of our circular hulls contributes very positively to the requirements of BENG. BENG (near-zero energy buildings) comprises the energy performance requirements for new buildings in the Netherlands. All permit applications for new buildings must meet the BENG requirements as of January 2021. It goes without saying that we comply with this.
