  • Building and insulation materials

Contexte

In France, over 5 million buildings are classified as 'energy sieves,' with a significant share among public facilities. Massive amounts of energy are wasted, fueling the climate crisis and straining local budgets. Current solutions rely on heavy renovation works that are costly, time-consuming, and often out of reach, while the urgency of the situation calls for faster, more effective actions.

Acteurs

Local authorities, as primary managers of public buildings, face soaring energy costs. The State sets ambitious goals for efficiency and renovation, yet available resources remain insufficient. Private operators offer solutions that are often complex and costly, while citizens demand rapid, visible action. Between budget constraints and the climate emergency, French stakeholders struggle to find effective responses.
