ABSTRACT
ABSTRACT This paper presents the Belgian approach to mainstream LCA in the construction sector. This approach includes three main initiatives. Firstly, an LCA method and expert model, called MMG, was developed to assess the environmental impact of building elements and buildings in a harmonized way. Secondly, a national database with specific data for Belgian construction materials based on Environmental Product Declarations (EPDs) was established. Thirdly, the MMG expert model was translated to a web-based calculation tool, called TOTEM, which is oriented towards designers and building stakeholders. An overview of these three main initiatives is given in this paper.
