If you operate a tertiary building of over 1,000 m², the tertiary decree (Éco Énergie Tertiaire scheme) requires you to gradually reduce its energy consumption and to declare your consumption on the OPERAT platform. Owners and occupants share responsibility for compliance. Here is what that involves and how to get organised.
Who is concerned by the tertiary decree?
Tertiary buildings, parts of buildings or complexes of over 1,000 m² are concerned. This notably covers offices, retail, warehouses, and healthcare or education premises, whether public or private. Owners and occupants share responsibility for compliance.
What are the reduction targets?
The decree sets progressive targets for reducing final energy consumption, with deadlines at several horizons, relative to a reference year. An absolute-value alternative, based on thresholds per activity category, is also available. The chosen method depends on the building's initial performance: check the applicable targets and deadlines on the OPERAT platform.
How to declare on OPERAT?
Consumption is declared on the OPERAT platform, managed by ADEME. Rigorous tracking of metering data is therefore essential, ideally backed by an energy-efficiency action plan. Beyond compliance, these actions durably affect the energy bill. At Eneffic, we support building managers with our energy monitoring and audit solutions.
Reach compliance in 3 steps
Set the reference year
Choose the method (relative or absolute) based on building performance.
Declare on OPERAT
Consolidate metering data and submit it on the platform.
Roll out the action plan
Prioritise efficiency actions and measure results over time.
