What C4E. does
C4E is a French Building Management Systems (GTB/GTC) integrator founded in 1980 and headquartered in Saint-Pierre-du-Perray, Île-de-France. The company designs, installs, commissions, and maintains centralized technical management and automation systems for energy production and distribution sites — including geothermal plants, district heating networks, boiler rooms, and commercial/institutional buildings. Its technical scope spans HVAC automation, PLC-based control (using platforms such as TREND, Distech Controls, Schneider, Siemens), SCADA supervision (NIAGARA, PCVue, CITECT), remote telegestion, and fire and gas detection systems for ERT-classified sites.
C4E's commercial model is project-based enterprise sales: study → design → installation → commissioning → recurring maintenance. Revenue is generated primarily through one-time integration contracts with major French energy operators and property managers (Dalkia, ENGIE, IDEX, Klepierre, GTPC), supplemented by recurring maintenance subscriptions. The company operates as part of the VERELEC Group, drawing on intra-group fire detection, gas detection, and high-voltage capabilities, and runs a team of 70+ specialists combining automation and electrical expertise.
C4E is geographically concentrated in Île-de-France, with offices in Saint-Pierre-du-Perray (HQ), Nanterre (opened 2024), and Bussy-Saint-Georges (second agency opened January 2026). The customer base is heavily weighted toward large French utilities and energy network operators, with marquee projects including the Ris-Orangis geothermal installation (570 kW reinjection pump, 15–20 MW thermal capacity) and a three-year GTB modernization across 24 Yvelines colleges with ENGIE. The company reports an average of 22% energy savings on optimized installations and received its first EcoVadis "Committed" label in May 2025.
