What ICOFLUIDES does
ICOFLUIDES is a privately held French thermal and fluid engineering consultancy headquartered in Rennes, France, founded in 1991 and operating as a SARL. The group is structured around two sister entities: ICOFLUIDES Ingénierie, which delivers thermal regulatory studies (RT2012, RE2020, ThCE-ex), fluid engineering (HVAC, ventilation, plumbing, fire protection, electrical/CFO-CFA), BIM 3D design in Revit, dynamic thermal simulation (Pleiades+COMFIE), energy audits, Décret Tertiaire compliance, and construction monitoring for residential and tertiary buildings; and ICOFLUIDES Maison, a specialist bureau d'études focused on regulatory thermal studies for individual houses, RE2020 compliance, energy audits, and MaPrimeRénov subsidy support. The firm is led by co-founder and President Yann DAGAULT alongside General Director Julien LE NORMAND and Technical Director Dimitri COUILLARD, with a total team of approximately 27 engineers and technicians supported by OPQIBI (1331, 1332), RGE, ERE, HQE, BREEAM, NF Habitat HQE, and Effinergie credentials.
The business model is professional services revenue from project-based engineering study fees, with one-off engagements ranging from small individual homes to large tertiary facilities (offices, R&D centers, data centers, hotels, healthcare buildings). GTM is sales-led and enterprise-field-sales driven, with direct engagement of property developers (promoteurs immobiliers), architects, property owners, and building managers from early design phases through construction completion. Channels are predominantly direct relationships, architect and developer referrals, and the company website's project portfolio, supplemented by LinkedIn presence for both Ingénierie and Maison entities. In 2023 the firm studied 380,000 m² of tertiary buildings and 3,031 residential units, with disclosed project contract values of €59.5M (tertiary fluid engineering) and €76.9M (residential fluid engineering). Named clients include Valeo (Mobility Tech Center), Orange Labs (Cesson-Sévigné), Crédit Agricole Brie Picardie (Chessy), Technicolor, Marriott/B&B Hotels, Mercure/Ibis Budget, CPAM, and architects MVRDV, Philippe Dubus, and Champenois, with multi-department French geographic coverage anchored in Bretagne and extending to Île-de-France, Normandie, Centre-Val de Loire, and Pays de la Loire.
Revenue mechanics rely on credentials-driven trust signals (OPQIBI/RGE certifications enable client access to government subsidies), high-touch project delivery, and a hybrid B2B/B2C model: ICOFLUIDES Ingénierie serves enterprise property developers and architects on larger tertiary and collective housing projects, while ICOFLUIDES Maison addresses individual homeowners through the MaPrimeRénov 'Mon Accompagnateur Rénov' program. The firm holds no external funding, has no institutional or PE/VC ownership, and has financed growth entirely through partner reinvestment and operating cash flow since 1991.

ICOFLUIDES competitors and assessment
Company assessmentDirect peers
- AMOES: French building energy and environmental engineering consultancy specializing in thermal studies, fluid engineering, and regulatory compliance (RT2012/RE2020) for residential and tertiary buildings. Comparable in scope, customer base (architects, developers, homeowners), and reliance on French thermal regulatory expertise.
- OTE Ingénierie: Independent French building engineering consultancy offering thermal studies, fluid engineering, and environmental certifications (HQE, BREEAM) for tertiary and residential projects. Closely comparable niche specialization and client segments.
- ALTEREA: French energy and environmental engineering consultancy focused on building energy performance, renovation, and decarbonization. Comparable services (thermal studies, fluid engineering, RE2020 expertise) and similar B2B professional services model serving property developers and architects.
- ITF (Ingénierie Tous Fluides): French bureau d'études specializing in fluid engineering (HVAC, plumbing, fire protection) and thermal engineering for buildings. Directly comparable offering across fluid and thermal engineering service lines.
Broad incumbents
- EGIS: Large French engineering group operating across buildings, infrastructure, transport, and energy. Its buildings division offers thermal and fluid engineering comparable to ICOFLUIDES, but within a far larger service portfolio and with materially greater resources.
- SETEC: French engineering group with significant building services and energy engineering capabilities, including thermal and environmental consulting. Comparable in technical offering to ICOFLUIDES but operating as a diversified national group rather than a regional specialist.
- ARTELIA: Major French engineering group with a dedicated Building, Energy & Industry division offering thermal engineering, HVAC design, and environmental consulting at national and international scale. Overlaps with ICOFLUIDES's core services but as part of a much broader multi-disciplinary portfolio.
