La Maison du Passif

What La Maison du Passif does

La Maison du Passif is a French non-profit association (association loi 1901) headquartered at 47 Avenue Pasteur, 93100 Montreuil, that operates as the exclusive French affiliate of the German Passive House Institute (PHI) in Darmstadt. It promotes ultra-low-energy "passive building" construction in France by distributing and certifying PHI standards, delivering professional training, and maintaining a community around CEPH-certified practitioners, project owners, and manufacturers.

Its product stack comprises (i) professional training — the CEPH Formation programme (six modules, priced €2,233–€3,108 HT), the PHPP Expert+ advanced course, and the "Manager un projet passif" course — all delivered through Qualiopi-certified subsidiary LMPP since December 2022 and therefore eligible for French public-training funding; (ii) software distribution — PHPP (€413.40), DesignPH (€420), and a bundled PHPP+DesignPH offer (€640); (iii) passive-building certification and labelling services; (iv) technical publications including Cahier Technique volumes (€42), Passimag', and L'Essentiel; and (v) the Passibat.MydatBIM.com BIM marketplace, including a paid "Ambassador" tier for product manufacturers at €2,000 (reduced from €3,140). Community-facing surfaces include the annual Festival Passibat' (rebranded for 2026 with ~650 visitors), regional events (Passi'Breizh, Passi'Optim), and the Trophées du Bâtiment Passif awards.

The business model is multi-stream association revenue: training fees, software license distribution margins, certification/labelling fees (quote-based), publication sales, membership dues, and manufacturer marketplace subscriptions. Customers are architects, thermal engineers, project owners and developers (including social-housing landlords), public authorities, and building-product manufacturers. Since 2020, 473 professionals have been trained across four CEPH sessions with a 65% exam pass rate, and the association maintains a LinkedIn following of 10,158+. Leadership currently identifies Franck Janin as President, with prior President Ivan Baudouin referenced in earlier materials.

Scale indicators11 records

Recent moves8 records

Expansion highlights4 records

Broad incumbents

• Passive House Institute (PHI): The international body that developed the Passivhaus standard and PHPP software, headquartered in Darmstadt, Germany. La Maison du Passif acts as its exclusive French affiliate and certifier, making PHI the most directly comparable organization (global parent) for the certification, training, and software distribution activities.
• HQE (Alliance HQE-GBC): French leading sustainable building certification body (HQE, BREEAM France) with broader environmental scope than passive house. Comparable as a French certification and training ecosystem, but covering a wider range of sustainability criteria.

Direct peers

• Effinergie: French association promoting the BBC (Bâtiment Basse Consommation) label and its successors, including the Effinergie+ and E+C- labels. A direct French peer in energy-efficient building certification, training, and label administration, and a potential competitor for French policy-driven building standards.
• EnerPHit / Passive House Trust (UK): UK organization promoting Passivhaus standards, offering training (CEPH-equivalent) and certification services. Closely comparable mission and revenue model within another European national market.
• IG Passivhaus (Passivhaus Austria): Austrian PHI affiliate that performs a comparable role for Austria: certifier, training provider (including certified designer / CEPH equivalents), software distributor, and event organizer. Most structurally similar international peer to La Maison du Passif.
• Passivhaus Institut Ireland / Irish Passive House Association: National passive house association for Ireland providing training, certification, and industry events. A direct peer as another PHI-affiliated national association serving a similar professional and certification ecosystem.

Others

• IZODOM: Polish-family-owned manufacturer of passive construction materials, PHI-certified, and a partner of La Maison du Passif (sponsor of the first Passi'nergie networking event). Comparable as an industry ecosystem participant but operating in materials manufacturing rather than certification/training.
• CINOV (Fédération Française des Métiers de l'Ingénierie): French national federation of engineering and consultancy chambers, partnering with La Maison du Passif for Passi'Breizh. Comparable as a French professional-services federation representing independent engineering professionals, but with a much broader mandate.

Regional players

• Envirobat Grand Est: French regional sustainable construction center providing training, technical resources, and certification-adjacent services. Comparable as a French non-profit offering professional education and resources in green building, but with a regional rather than national scope and a broader sustainability mandate.
• Batylab (Bretagne Environnement): Regional sustainable construction center in Brittany that co-organizes Passi'Breizh with La Maison du Passif. Comparable as a French training-and-resources ecosystem organization with a regional sustainable-building mission.
