What ACTIF does

ACTIF (A.C.T.I.F — Applications Climatiques Thermiques Ingénierie Fluides) is a French thermal and energy engineering consultancy, founded approximately two decades ago and headquartered in Le Bourget-du-Lac, Savoie. The firm operates as a wholly-owned subsidiary of Groupe Aliénor, a diversified French engineering group with 230+ experts across 16 agencies throughout France. ACTIF specializes in engineering consulting for luxury hospitality projects (5-star hotels, grand luxury chalets in Courchevel) and historical monuments requiring heritage preservation compliance, serving both public and private sector clients including LOV HÔTEL COLLECTION, Baccarat, Vallat, Ville d'Annecy, POMA, and ONERA.

The company delivers three integrated service lines. Maîtrise d'œuvre provides project management and coordination acting as the single point of contact from conception through delivery. Génie Climatique covers climate engineering including RE2020 regulatory calculations, Bilan Carbone carbon footprint assessment, and design of HVAC, plumbing, and smoke extraction systems. Électricité delivers electrical engineering covering strong and weak current networks, building automation, fire safety, and access control systems. These are typically sold together as comprehensive technical building solutions for complex projects.

Revenue is generated through project-based professional services contracts with fees negotiated per engagement; pricing is not publicly disclosed. Disclosed project values across the customer portfolio range from €300K HT (Ville d'Annecy) to €22M HT (LOV HÔTEL COLLECTION Versailles). The firm markets directly through project portfolio references and a modest LinkedIn presence rather than paid marketing, and operates with an 11-50 employee standalone headcount while drawing on the broader Groupe Aliénor network for delivery on larger engagements.
