Optimizing Energy Consumption of Large Public Facilities in Italy


ENGIE deployed C3 AI Energy Management™ in Italy to enable large municipal and commercial customers to analyze energy consumption and reduce energy expenditure. ENGIE configured C3 AI Energy Management with custom analytics, data integrations, and complex asset hierarchies for their customers using the development tools on the C3 AI Platform.

C3 AI and ENGIE partnered over the course of 16 weeks to implement C3 AI Energy Management as the “Clara Domus” solution for more than 600 public facilities in Northern Italy, in response to a business need identified by the Italian Ministry of Economy and Finance (MEF). In the next phase, ENGIE Italy is expanding Clara Domus to thousands of facilities to benefit cities and other public customers.
