Scilab and Cloud solutions for Hybrid Twin

Going back on the Energy consumption optimization use case from Sanofi, this is the vision developed by ESI Group around the notion of Hybrid Twin of an HVAC system (Heating, Ventilation & Air Conditioning).

The Hybrid Twin concept

 From a technical point of view, a Hybrid Twin is a combination of physical-based and data-based modeling:

Application to HVAC optimization


  • Inefficient control of HVAC (Heating, Ventilation & Air Conditioning)
  • HVAC = 60 % of energy bill (example: 500k€/year/site)


  • Save 10M€+ /year in energy bills worldwide
  • Energy efficiency at 100+ industrial sites

Industrial IoT enriched by simulation
