CEA (Commissariat à l’énergie atomique)


pngCEA_logo_HautCEA is a major research institute in France with a staff over 16000 people and with a broad field of expertise in all energy related aspects. Within CEA, a department is dedicated to solar energy and energy efficiency in buildings. This department is the major player of the French National Institute for Solar Energy (INES), located in Alps region. Currently, CEA-INES is about 300 persons, and is divided in six laboratories. The main activities of CEA-INES are:

  • Technological research: advanced modelling and new concepts,
  • Applied research: assistance to innovation for material, processes, products; assistance to products development, technology transfer,
  • Systems design: simulation tools, climatic analyses, monitoring on real sites.
  • Characterization, tests: assistance on products, tests program,
  • Training on solar systems, standards development,
  • Demonstrations: validation at the end user level in real environment for specific application of a product or a system.

Role in City-zen

CEA-INES will assist Ville de Grenoble in the development of the smart district heating network. In particular, CEA-INES will be involved in the design, the simulation and the optimization of the demonstration project and will provide assistance in the scientifical and technical fields.



  • The Project

    A city operating entirely on clean energy. In theory, it's possible. But in real life? How to integrate new solutions in existing buildings, systems and people's lives? What are the technical, economic or social barriers? And how to overcome these? That's what we've learned by doing in 20 projects in Grenoble and Amsterdam.
