About us
We are an independent verification body for environmental information on (construction) products. Our task is to put data to the test – so that ecological decisions can be made on a reliable, traceable, legally compliant, and independent basis.
Following the principle "What you can't measure, you can't manage," we create the foundation for credible environmental data, because a sustainable (construction) economy needs reliable facts.
Manufacturers, planners, auditors, and other stakeholders benefit from our verifications, which meet the highest technical and methodological standards. This is how we ensure: Those who work with our verified data can rely on quality, transparency, and substance.
As a (prospective) accredited validation body and future Notified Body for the essential characteristics listed in the durability of performance regarding the control of the assessment of ecological sustainability pursuant to the Construction Products Regulation (BauPVO), we guarantee complete independence, confidentiality, and impartiality in all assessments – in accordance with the requirements of ISO/IEC 17029.
