What PLAN02 does

PLAN02 is a privately held French eco-design engineering consultancy (bureau d'études) headquartered at 89 rue de Reuilly in Paris's 12th arrondissement, founded in 2008 by the nine associated architects of the PLAN01 architecture collective. The firm specializes in building thermal studies under French regulations (RT2012, RE2020), Life Cycle Assessments (ACV) for new buildings, low-carbon and biosourced material specification, and support for environmental certifications including HQE, BDF, BBCA, E+C-, Effinergie+, BREEAM, and PassivHaus. It holds OPQIBI RGE qualifications 1331, 1332, and 1333 (obtained June 2022), BREEAM accredited professional status, and PassivHaus training credentials.

The firm's service portfolio centers on three OPQIBI-qualified core offerings: thermal regulatory studies for individual houses, thermal regulatory studies for collective residential and tertiary buildings, and Life Cycle Assessments for new buildings. Supporting services include RE2020 training cycles and certification accompaniment. Notable proprietary technical assets include a custom-built modular microsoufflerie (miniature wind tunnel) used to test natural ventilation strategies on reduced-scale building models, and an internally accumulated library of experimentally verified building performance and LCA data from years of PLAN01 projects. The team combines dual architect-engineer credentials (notably INSA Strasbourg architecture plus climate engineering) with specialized thermal engineering from Université de Picardie Jules Verne and urban engineering from UTC Compiègne.

PLAN02 operates as a quasi-exclusive embedded environmental engineering partner to the five architecture firms of the PLAN01 collective: Atelier du Pont, KOZ Architectes, Atelier Phileas, Ignacio Prego Architectures, and Jean Bocabeille Architecte. The nine associated architects of PLAN01 retain ownership of PLAN02, which generates professional-services revenue on a project-by-project basis from these five studios and, through them, from public and private developers across France (Paris, Lyon, Nice, Rouen, Amiens, Tours, Rennes), French overseas territories (Martinique, Mayotte, Guadeloupe), and occasionally abroad (Gabon, Sardinia). New client acquisition is deliberately limited, and go-to-market is consultative and relationship-driven, with no external resellers, self-serve channels, or third-party funding evident.

Core offering

PLAN02 is an eco-design engineering consultancy (bureau d'études) that performs regulatory thermal studies (RT2012 / RE2020), Life Cycle Assessments (ACV) for new buildings, and provides environmental certification support (BREEAM, HQE, BBCA, E+C-, Effinergie, BDF, PassivHaus) for architecture firms and developers. The firm also delivers RE2020 training sessions for partner architecture agencies and applies bioclimatic design methodology integrating site insertion, energy efficiency, and low-carbon material specification across residential, tertiary, educational, healthcare, and public infrastructure projects in France and French overseas territories.

Product overview

PLAN02 operates as an eco-design consulting firm (bureau d'études) specialized in building thermal studies, low-carbon materials assessment, and environmental certifications. The core service portfolio centers on three OPQIBI-qualified offerings: Thermal Regulatory Studies (RT2012/RE2020) for individual houses and collective/tertiary buildings, and Life Cycle Assessment (ACV) studies for new buildings. Supporting services include RE2020 training sessions for architecture partners and environmental certification support (BREEAM, HQE, BBC, Effinergie, BDF). The firm primarily serves the five architecture agencies within the PLAN01 collective (Atelier du Pont, KOZ Architectes, Atelier Phileas, Ignacio Prego Architectures, Jean Bocabeille Architecte).

Products and services

• Etude Thermique Règlementaire (RT2012 / RE2020) Regulatory thermal studies covering RT2012 and RE2020 energy performance compliance for individual houses (qualification 1331) and collective housing and/or tertiary buildings (qualification 1332). Delivered to architecture firms and developers to certify environmental regulatory conformance for new construction and rehabilitation projects.
• Etude ACV Bâtiments Neufs (Life Cycle Assessment) Life Cycle Assessment studies for new buildings, evaluating environmental impacts from material production through transport, construction methods, building operation, and end-of-life deconstruction/recycling. Delivered under OPQIBI qualification 1333 to inform low-carbon material decisions and support labels such as E+C-.
• RE2020 Training Sessions (Cycle de conférences RE2020) Educational training sessions on the French Environmental Regulation 2020 (RE2020), covering energy, carbon, and environmental performance standards, delivered to architecture firms to build internal competencies ahead of regulatory enforcement.
• Environmental Certification Support (BREEAM, HQE, BBCA, E+C-, Effinergie+, BDF, PassivHaus) Consultancy and accompaniment for architects and building owners pursuing environmental certifications, including BREEAM (PLAN02 holds BREEAM Accredited Professional status), HQE, BBCA, E+C-, Effinergie, BDF (Bâtiment Durable Francilien), and PassivHaus. Supports project teams across certification procedures, documentation, and target achievement.
• Bioclimatic Design and Eco-Conception Consultancy Integrated eco-design consultancy applying bioclimatic methodology that leverages natural elements (air, sun, water, heat) to minimize energy consumption, maximize building autonomy, and address site insertion, energy efficiency, low-carbon and biosourced materials, reversibility, and adaptability over time. Delivered as embedded support throughout design and construction phases, plus post-delivery performance observation.

Quantifiable outcome

• Projects regularly achieve RE2020 E3C1 levels, biosourced level 3 certification, BDF Silver/Argent, and E+C- E3C1/E3C2 labels.
