ACM INGENIERIE

What ACM INGENIERIE does

ACM Ingénierie is a French independent fluid engineering consultancy (bureau d'études fluides) founded in 2011 and headquartered in La Montagne near Nantes, with additional offices in Cesson-Sévigné (Rennes) and Bourgoin-Jallieu (Lyon), and a team of approximately 20 specialized engineers and technicians. The firm designs and supervises HVAC, refrigeration, electrical, plumbing, air treatment, fire protection, and renewable energy systems for professional clients across five verticals: large-scale retail (GMS, including Système U, E.Leclerc, Carrefour, Intermarché), collective housing, tertiary/commercial, industrial, and public-sector buildings, with a documented early-mover specialization in natural refrigerant systems (CO2 subcritical/transcritical, propane, ammonia) since 2012.

The company's underlying technology stack combines conventional BET fluides deliverables (CVC studies, transformer sizing, APSAD R1/R5 sprinkler design, NF-EN 12.845 fire protection) with BIM-based 3D coordination, GTC/GTB building management integration, and an in-house digital team supporting visualization and project tools. Reported performance outcomes include 25% energy savings from CO2 over glycol-based systems, 32% consumption reduction at the E.Leclerc Saint-Grégoire decarbonation project, and 60% targeted energy impact reduction per square meter at Super U Evron via GTC implementation. ACM maintains core technology partnerships with Danfoss Climate Solutions, EPTA France, Mitsubishi Electric, Bitzer, Güntner, LU-VE, Enex, and Uxello, alongside architectural alliances with Marraud Architecture & Ingénierie and PAD Architectes.

ACM operates a project-based professional services model with fees determined per scope, selling directly to enterprise and public-sector clients through referrals, architect partnerships, and a website case-study library; pricing is not publicly disclosed. The firm is privately held as a SAS with €30,000 capital social, owned via L+C Invest (Présidente, represented by gérant Claude Chiron), with no external private equity, venture, or institutional investment evidenced. Revenue is not disclosed, the international footprint is limited to a first African retail reference in Port-Gentil (Gabon, October 2025) with Mercure International of Morocco and TECHNIREF, and growth has been organic and measured rather than venture-backed.
