AQSI uses a database. In it, we collect information about the added value that construction products, building parts and design elements can affect the users of a building. Does your product added value, users are better off in a building where your product is applied? Please inform about the possibilities of participation in the AQSI database.

Participation in the database
  • Companies can participate in the in de AQSI database.
  • The participation request will be screened by the Nieman Group. Participation will be permitted when the product has proven its added value for the end user of the building.
  • Inclusion of the products in the AQSI database has no security that the product will be prescribed in an AQSI assessment. The AQSI assessor is responsible for the content of the assessment.
  • Price on request
