The MMG project originated from a lack of environmental classification systems specific to the building context in Flanders/Belgium for building professionals and governments. In the project an expert calculation model was developed together with a limited database of environmental profiles of 115 building element variants, specific for the Flemish/Belgian building context based on the principals of life cycle assessment (LCA).
After the first MMG project, a reference task was set up, to update the methodology and its calculation model with new legislations and insights and to expand it with new features, such as:
- Continuous update of the methodology
- Conformity with EN 15804, EN 15978, EPC-structure and PEF Guide
- Additional impact categories
- Expansion of the database with new environmental profiles
- Sensitivity analyses
- Inclusion of renovation options
- Integration of energy and indoor air quality
- Integration in broader sustainability schemes
Also several innovative cases in the current building practices are investigated with MMG. The MMG-model is also applicable in more specific research, e.g. Design for Change, where the environmental impact of adaptable and/or multi-use building solutions is investigated. The development of user-friendly designer and policy instruments based on MMG is the next major development step to be taken. The designer instrument will be connected with the federal database for environmental product declarations as described in the Royal Decree of 22 May 2014.
