Innovation and Renewable Energy (RE)

Since its inception, innovation has been a cornerstone of BEST ENERGIESdevelopment and has always allowed us to stay one step ahead of our competitors.

But whether major or incremental, innovation is never self-serving; we innovate and seek pragmatic, useful, and economically viable solutions for our clients, as well as internally, at various levels: process innovations, product innovations, and organizational innovations.

The societal transitions we support on behalf of our clients drive us to develop 5 key areas to meet their current and future needs:

  • Energy efficiency through research in instrumentation, or how to leverage metrology and artificial intelligence to improve energy management.
  • Renewable energies (particularly biomass, hydrogen, and solar) and the reduction of climate impacts through the execution of studies and engineering missions.
  • The development of solutions (products) to ensure decentralized energy production and local consumption (off-grid); heating and cooling networks, large-scale integration of renewable energy into electricity production.
  • Digital engineering through the development of software tools and the integration of BIM (Building Information Modeling).

These major challenges are the opportunities of tomorrow to continue satisfying our clients and contributing to a sustainable world.

Mobilize a skilled team
Energy efficiency and the development of renewable energies rely on the expertise of a qualified team.

The Climate Fresk enables everyone to understand the mechanisms, scale, and complexity of the issues related to climate change, so they can take ownership of them and take action. Two of our team members, including our President, are trained.

2025 will be the year we obtain the LUCIE label, aligned with ISO 26000 (the international standard for sustainable development and CSR).

Deux de nos collaborateurs, dont notre Président, sont formés.
