Legal context: Decree concerning building passport, 30th of November 2018.

Partner organizations involved: Different regional (Flemish) authorities: Vlaams Energie- en Kimaatagentschap, OVAM, Departement Omgeving, Agentschap Wonen in Vlaanderen en Agentschap voor Infrastructuur in het Onderwijs (expansion towards a building passport for non-residential buildings in 2024
