Solenbat optimises the active energy efficiency of buildings

The Solenbat project aims to maximise the capacity of a building to become an energy provider. Studies and experiments focus on reducing consumption, local PV electricity production, energy storage and smart management of the exchange of electricity with the public grid.


The Smart Building is controlled by an energy information system (EIS). The data is displayed on screens placed at various locations in the building.

The challenges of the project

  • Measure and analyse energy consumption, in accordance with the five uses of L2 Building Regulations.
  • Maximise photovoltaic production and self-sufficiency from the renewable energy produced by Smart Buildings. 
  • Optimise the electrical flow exchanged with the grid according to fluctuations in the price of electricity.
  • Define technical solutions and economical optimisation models that are easy to reproduce.


Socomec energy storage solutions have been used in the four demonstrators of the Solenbat project.
Developed under this project, Socomec's new industrial and logistics centre automatically adjusts its production and energy consumption according to outside weather conditions (current or forecast) and to the number of people on the premises (week, weekends, number of occupants...), while maintaining the thermal comfort of the occupants.
