ELEMENTS FOR RENOVATION PLAN
- Campaign of statements of consumptions following a typology of constructions to situate local buildings and very local climate conditions and then optimize interventions regarding to their economical balance
- Communicate with the population and employed to collect and valorize ideas for better practices “social capital”
- Search an optimal global final state in building renovation “no half intervention”
- coordinate territorial system for all actions on energy efficiency, at least having the same a reference system.
