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.
