ITHERM CONSEIL

What ITHERM CONSEIL does

ITHERM CONSEIL is a French technical design firm specializing in energy and climate engineering, founded in 2004 and headquartered in Gennevilliers, France. The company provides energy efficiency and transition services including thermal renovation, renewable energy integration, and infrastructure engineering, organized around four strategic poles: energy efficiency and lifecycle of building portfolios (Patrimoines), energy transition of territories (Territoires), industrial decarbonation (Industries), and engineering and greening of energy infrastructure (Engineering). Its service portfolio spans consulting and studies, project management assistance (AMO), engineering and design, and operational tracking services.

ITHERM CONSEIL is part of the MANERGY group, which consolidated its subsidiaries under a unified brand identity in April 2024, operating 26 local agencies across France with approximately 400 employees. The firm serves a diverse customer base including social housing providers, university hospital centers, municipalities, energy unions, industrial groups, and private property owners, with notable framework agreements with RESAH (healthcare purchasing central) and SIGEIF (Greater Paris energy syndicate). The company differentiates through deep expertise in French energy financing mechanisms including CEE certificates, PACTE Industrie, Diag Décarbon'Action, and Fonds Chaleur programs.

The business model is built on professional services revenue through direct enterprise field sales across its 26-agency network, with pricing not publicly disclosed and customers directed to contact the firm for expert project consultation. The go-to-market relies on proximity-based service delivery, thought leadership content marketing via blog, webinars, and LinkedIn, and institutional partnerships rather than digital self-service channels. The company holds the LUCIE sustainability label since January 2024, reflecting its commitment to responsible corporate practices.
