IDEX from 1963 to the present day: innovating together to shape the world of tomorrow
A family-run company built on a human scale
Founded in 1963, Idex has become a leading name in the renewable energy industry. Over the years, our group has succeeded in anticipating and taking action in response to climate change. Idex is France’s leading medium-sized energy services company. We are now experts in all energy solutions, embodying a solid alternative to operators that work with major fossil fuel energy (gas and electricity) producers.
Idex: Leading the way in energy transition
Our aim is to optimize, innovate and revolutionize our sector in order to support you in your different activities. Our technical expertise is plowed into ensuring high technical, energy, cost-saving and environmental performance in buildings. Years before other companies, we had noted a worrying trend in excess energy consumption in different types of buildings, and realized how urgent it was to make changes to our sources of energy supply. Consequently, we then began taking a closer look at renewable energy. Idex now boasts inside-out knowledge of all renewable energies: Wood fuel/biomass, near-surface and deep geothermal energy, anaerobic digestion, wind power, solar photovoltaic (PV) and solar thermal energy, cogeneration, and more.
The IDEX method draws on an integrated approach to energy infrastructure with guaranteed results, the aims of which are:
- Managing local energies in an efficient manner
- Widening our offer to encompass technical management for buildings and specific facilities and structures in the public sphere
- Maximizing business synergy, • Ensuring all structures operate in smart mode
- Optimizing performance to align with climate and budgetary concerns
- Creating a virtuous circle in which operating costs decrease as a result of energy savings
- Assessing contractual performances and securing them in the long term.
We provide solutions to the region’s different sectors: State Services, Local Authorities, Housing, Private/Tertiary Sector, Health, Industry, etc. All have immediate local energy management needs.
Our overall performance is driven by the following three priorities: Ensuring well-being, operating within a carbon-neutral ecosystem, helping to improve quality of life.
Idex: Passion is the best energy we have
Successful completion of our projects is down to the hard work and unwavering commitment of all our members of staff and their shared values: building sustainable cities. The group’s success is a joint effort in which each and every one of us plays our part depending on individual areas of expertise.
