Under the supervision of our French partner CSTB, we will test the COLLECTiEF system on a small-scale basis in the G2Elab, a “living lab” in Grenoble, France.

G2Elab is a research laboratory from the University of Grenoble, located in the Green’ER building. It partly acts as a living lab supporting research and teaching in the field of sustainability and will be used as a small-scale pilot where the COLLECTiEF system will be implemented and tested.

The living lab is equipped with a large number of meters and sensors that allow testing the algorithms and control strategies in a real energy system to ensure the correct operation of the COLLECTiEF system before installation on the other pilots.

The performance will be compared to an equivalent zone of the building (same orientation and usage but another floor of the building) in order to assess the robustness and performance of the algorithms.
