Context
The Alpes-Maritimes Departmental Council aims to define and manage a renovation plan for its real estate portfolio of 177 sites, incorporating an energy performance trajectory to meet the objectives of the French regulations (Décret Tertiaire), which applies to its 71 middle schools and 30 additional sites. CD06 needs to map current energy performance and define energy consumption trajectories over time in order to visualize the full scope of investment needs.
Our solution
Generate “Tertiary Decree” scenarios to identify actions that contribute to improving the energy performance of buildings Identify the budget portion linked to energy performance actions Identify potential energy savings based on the planned actions
What Oxand delivered
Impact-based investment visibility
Visualize investment needs based on their impact in terms of energy performance, asset aging, and risks
Energy trajectory definition
Anticipate future gains and define the energy trajectory in order to justify upcoming investments
Questions about this reference
What estate does the Alpes-Maritimes Departmental Council manage?
A portfolio of 177 sites, of which 71 middle schools and 30 further sites fall within the scope of the French tertiary-sector energy decree.
What is the Décret Tertiaire and why does it drive a renovation plan?
It is the French regulation requiring large tertiary buildings to cut their energy consumption against a reference year, on a set trajectory. Because the obligation is a trajectory rather than a single target, it has to be planned as a programme of works rather than met building by building.
What did the council need to see first?
Its current energy performance mapped across the estate, and consumption trajectories over time, so that the full scope of the investment need became visible before any commitment was made.
How is the energy part of the budget separated out?
The scenarios identify which actions contribute to improving energy performance, and what share of the budget those actions represent — so the energy obligation can be costed distinctly from the rest of the renovation plan.
What does the council gain?
Investment needs it can read by their impact on energy performance, asset ageing and risk at once, and an energy trajectory defined far enough ahead to justify the investments it implies.
