Context

The Yvelines Departmental Council (CD78) aims to implement a strategy to meet the energy performance objectives it has committed to under the French Regulations (Tertiary Decree), while optimizing investments to reduce its maintenance backlog. Oxand supports the Council by highlighting priority operations and identifying the impact of works in terms of asset aging and safety, as well as improvements in energy performance. Without a maintenance strategy, the grey debt is expected to triple by 2050.
