BET ECOTEC

What BET ECOTEC does

BET Ecotec (legal entity Ecotec SAS) is a French engineering consultancy (bureau d'études techniques) founded in 1965 and headquartered in Rocquencourt, Île-de-France. The firm provides technical studies, audits, design, and project management (maîtrise d'œuvre) for building technical installations in the second œuvre — heating, ventilation, electricity, plumbing, fire safety, and renewable energy systems. It also delivers energy audits, ADEME-type diagnostics, and operational monitoring via a dedicated Extranet site for remote building-owner oversight. Its service portfolio spans full project lifecycles: feasibility studies, AutoCAD plans and schematics, cost estimates, tender and execution files, construction supervision, and reception testing.

The firm holds OPQIBI, RGE, DPE, Coach Copro, and AFNOR certifications, which qualify it for French public-sector procurement and subsidized energy-renovation programs such as MaPrimeRénov'Copro. Its client base is concentrated in Île-de-France social housing operators (DOMNIS, BATIGERE IDF, ICF LA SABLIERE, ADOMA, EFIDIS, IMMOBILIERE 3F) and cultural/public institutions (Palais de Chaillot, Grand Palais, Réunion des Musées Nationaux, RIVP, Cité de l'Architecture et du Patrimoine). Notable projects include the Palais de Chaillot heating plant connection to CPCU district heating (reducing installed capacity from 11 MW to 4.9 MW), heat pump retrofits at Résidence Le Turenne and Hameau des Puits, and a cogeneration project at DOMNIS Bagneux coordinated with ENGIE Solutions and VIESSMANN.

Commercially, BET Ecotec operates a sales-led B2B model on project-based contracts, procured via public tenders and direct client engagement. Revenue is not publicly disclosed; the firm has a social capital of €150,000 and operates with 31 employees as a privately held SAS with no parent company, external investors, or M&A activity. Geographic scope is regional, limited to the Île-de-France market, with no disclosed expansion plans or funding signals.
