Byggvarubedömningen, or BVB, is a building materials assessment tool. It evaluates, proactively and systematically, the contents of a product and of the production process.

BVB also provides a common criteria and an evaluation standard based on seven factors: • Chemical content (declaration of contents) • Input materials (raw materials) • The construction phase • The management phase • Demolition • Residual and waste products • Indoor environment

These are weighted to come up with a final score: either "recommended", "accepted" or "to be avoided". In the online database, products have a final score and a product card containing the declaration of contents and the evolution outcome. The product cards are adapted for inclusion in the supporting documentation for product procurement and in the documentation of the construction project.

All companies affiliated to BVB insist on the use of environmentally approved products in their construction and management projects.
