Bastide Bondoux

What Bastide Bondoux does

Bastide Bondoux is a French thermal and environmental engineering consultancy group founded in 1981, headquartered in Chaponost (Lyon region) with additional offices in Paris, Nancy, and La Ciotat. The group comprises three wholly-owned entities: Bastide Bondoux (historical structure serving individual home construction since 1981), Bastide Bondoux Ingéfluides (created in 2017 for collective housing and tertiary buildings), and Synergisud (acquired/created in 1993 for thermal, acoustic, and indoor air quality studies and certified training). Services span preliminary and definitive thermal studies, dynamic simulations, RE2020/RT2012 attestations, environmental and Life Cycle Assessments (ACV), comfort studies (lighting, dynamic thermal simulation, IAQ), and renovation support including the Mon Accompagnateur Rénov' (MAR') mandate. The proprietary BéA software is the only study-firm-developed RE2020 carbon assessment tool in France, validated by DHUP in 2017 and approved by CEREMA in February 2023; supporting assets include the Espace Professionnel client extranet, EasyRéno 2024 household qualification tool, and a dynamic environmental database integrated with the INIES reference data.

The business operates as a B2B sales-led professional services firm, with project-by-project quotations and no public pricing. Customers include individual home constructors, real estate promoters and developers, architectural firms, and individual homeowners undertaking renovation; demand is driven by French thermal and environmental regulations (RT2012, RE2020) and government subsidy programs (MaPrimeRénov', Eco-PTZ). Distribution is direct via the four French offices and the online Espace Professionnel portal, supported by an annual RénoTour 360 roadshow, BB Flash newsletters, and partnerships including Pôle Habitat FFB, Athermys, and Agyre. The firm holds NF Etudes Thermiques, OPQIBI 1911, Qualiopi, and CERTIBAT certifications. Since October 2023, Bastide Bondoux has operated under the Bastide Bondoux Fédérateur holding following a merger with Groupe Impact Développement (ABM Energie Conseil, NRJ Diags, PMB Software), broadening the offering into energy consulting, controls, and building-industry software.
