Rhônalpénergie-Environment organized a study trip to attend an evaluation committee of sustainable buildings projects by BDM, the regional tool and approach of sustainable buildings in the Provence-Alpes-Côte d’Azur region (South of France). The BDM approach was born in Provence-Alpes-Côte d’Azur in 2008 and is also recently operational in the Languedoc-Roussillon region. This regional approach is based on a tool to assess the environmental quality of buildings, developed by representatives of the construction sector in Provence-Alpes-Côte d’Azur. Through a points system, projects get a score, and go through an evaluation committee at three distinct stages:
- The design phase
- The implementation phase
- The operational phase
The evaluation committee consists of a jury of a dozen members of BDM; it is open to the public. The project teams (owner, architects …) present their project during half an hour and are asked about their technical choices, materials used, energy performance achieved… Discussions are oriented so that the project is progressing towards greater sustainability, taking into account the various constraints to which it is subjected. At the end the jury validates the number of points obtained.
This evaluation approach relies on a participatory guarantee system: it is not a certification issued by a third body, but an evaluation and therefore a recognition by members of the profession.
The Rhône-Alpes delegation was able to participate in these discussions and found this method of evaluating sustainable buildings interesting in many ways:
- Publics, debates allow the profession to improve collectively
- The peer evaluation is a guarantee of quality
- The criteria grid allows influence public policies and subsidies
Under the MountEE project, it is planned to organize a public review of projects, on the same format as the evaluation commission of BDM. BDM could inspire a similar approach in Rhône-Alpes towards the massification of sustainable buildings.
This approach is also compatible with the European CESBA approach (www.cesba.eu).
