How did the Yvelines Departmental Council leverage Oxand Simeo to prioritize maintenance, improve energy performance, and prevent the growth of grey debt under the Tertiary Decree?
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.

What did we do?
Centralize knowledge of the asset portfolio and gain a clear, reliable view of performance status
Prioritize the most critical operations based on their energy savings and evaluate return on investment
Target key operations based on rehabilitation needs with a focus on sustainability
Simplify decision-making to ensure informed investments
Gains
38% reduction in energy consumption by 2050 under the maintenance and renovation scenario
Clear vision of portfolio performance (risks, aging, and energy efficiency)
Optimization of investments through the identification of operations offering the best cost-to-energy performance improvement-to-risk reduction ratio
Budget justification: by 2032, the annual budget would need to increase by 45% to implement the optimal scenario.
