OPTIMIZING YOUR ENERGY CONSUMPTION
REGULATIONS FOR REDUCING ENERGY CONSUMPTION BY 2050
New buildings:
- RT 2012 (thermal regulations): comfort and energy consumption requirements
- RE 2020 (environmental regulations): energy efficiency, carbon impact, summer comfort
Existing buildings:
The Tertiary Eco-Energy Decree (DEET) is a regulatory obligation that imposes a progressive reduction in final energy consumption in tertiary buildings over 1,000 m² in order to combat climate change.
The companies concerned by this measure must file their declarations on the OPERAT platform.
APER law (acceleration of renewable energy production): Article 40 of the APER law requires the installation of photovoltaic panels on existing outdoor parking lots by 2028, according to certain criteria.
ECO-ACTIONS, ONE OF THE PILLARS OF ENERGY CONSERVATION
We spend almost 200 days a year at the office. Our behavior there has a direct impact on energy consumption. There are simple ways to introduce energy saving measures in your company or business. Turning the heating down by one degree saves an average of 7% in consumption. You can make a real contribution by adopting a series of eco-friendly measures.
METROPOLITAN TOOLS
TO HELP YOU
Montpellier Métropole has developed tools to help companies and local authorities with their energy transition. The metropolitan authority also works in a network with the stakeholders who interact with companies on a daily basis.
Solar Energy Plan
Montpellier Métropole has developed an ambitious Solar Energy Plan for 2050, designed to promote the consumption of carbon-free energy in the area. This roadmap sets out the actions aimed at encouraging local private and public initiatives.
If you would like to determine the solar potential (thermal or photovoltaic*) of your roof, please refer to Montpellier Méditerranée Métropole's solar energy registry.
*Thermal: heat production - Photovoltaic: electricity production

Heating networks
A heating and cooling network is a centralized energy distribution system that can serve several consumers.
Before deciding whether you can connect to the network and use it, you can first check whether your area is served by a heating network by clicking on this link.
What are the benefits of connecting to a heating network?
- Rates are competitive and tend not to fluctuate much.
- Heating networks are supplied mainly by local, renewable, and recycled energy.
- Supply is secure and reliable thanks to a 24-hour on-call service throughout the year.
- Installations are managed by professionals, thus guaranteeing optimal energy and environmental performance of production systems.
- The technical area for heat delivery to your premises is relatively small, essentially comprising a heat exchanger and circulation pumps.

Montpellier Méditerranée Métropole Lighting Plan
The Lighting Plan is a voluntary initiative by the metropolitan authority, which, in addition to defining the area's policy in terms of artificial night lighting, also aims to raise awareness and inform all stakeholders about the fight against light pollution.
In this context, the Lighting Plan specifically refers to the regulatory elements contained in the decree of December 27, 2018, regarding light pollution
