ARKENOR

ARKENOR is a French environmental consultancy and building diagnostics brand operating as the advisory-and-compliance subsidiary of the NORMAXIS group, headquartered in Aix-en-Provence. It positions itself as an "AMO environnementale" — an environmental project management assistant that advises property developers and public contracting authorities (maîtres d'ouvrage) on environmental certification and regulatory compliance across residential, tertiary and regional frameworks. Its stated philosophy is "Beyond Compliance", and it stresses independence from certifying bodies: ARKENOR advises the client so that the client can obtain certification, but it does not itself certify. The brand covers the full range of French environmental certification schemes. For housing it cites NF Habitat HQE and BEE+, and for tertiary buildings HQE BD and BREEAM, alongside regional reference frameworks. Its work spans the upstream decision — which certification, at what level, with what strategy — and structured execution: scoping, documentary production, audit coordination and delivery files. ARKENOR describes its deliverables as "opposable evidence", meaning every assertion is tied to its source and method so that it can be audited by the third-party certifier. Beyond certification management, ARKENOR presents four areas of expertise: AMO, ecology, acceptance measurements and EMC metrology. Its ecological work includes fauna-flora expertise with the ERC sequence (avoid, reduce, compensate), and it also carries out measurements and diagnostics. Wikidata describes the entity as a French building diagnostics and regulatory measurement company covering air tightness testing, ventilation, acoustics and energy performance. ARKENOR operates from Aix-en-Provence across five French regions: Provence-Alpes-Côte d'Azur (PACA), Occitanie, Nouvelle-Aquitaine, Auvergne-Rhône-Alpes and Île-de-France. Its parent group, NORMAXIS, was founded in 2009 and is led by Cédric Plantaz; the group structures the environmental chain of real-estate projects through complementary subsidiaries. ARKENOR is a private, group-owned brand rather than a listed company.

ARKENOR is the environmental AMO and diagnostics brand within the NORMAXIS group, a French integrated environmental engineering and certification group based in Aix-en-Provence. The group's history, as described on its own website, begins with its founder Cédric Plantaz. Between 2004 and 2009 he entered the building sector with a DESS in civil engineering, worked on site as an OPC (scheduling, coordination and supervision), works engineer and technical controller, then led a team of HQE and BBC auditors at Cerqual. He also contributed to introducing dynamic thermal simulation into summer-comfort criteria. In 2009 Plantaz founded the environmental AMO GREENLOGIC in Aix-en-Provence, launching two R&D programmes that would become the group's proprietary tools: Efficarbone (site carbon measurement) and Effinature (integrating biodiversity into real-estate and development projects). Between 2009 and 2014 the business extended into technical engineering — thermal, acoustic and then fluids — and adopted BIM early. Plantaz became a trainer at the CESI engineering school, and the Efficarbone and Effinature programmes gained national recognition. In 2014 GREENLOGIC became NOVACERT, integrating activities under a single structure. The group continued to structure itself methodically: building technical foundations, developing its own method tools, forming a holding company, separating ISO 17065 roles and consolidating internal procedures. NORMAXIS presents this trajectory as a series of responses to concrete sector requirements rather than branding operations. ARKENOR appears as the group's advisory-and-compliance subsidiary, described on the NORMAXIS site as the "filiale conseil-conformité du groupe NORMAXIS". It carries the environmental AMO activity, advising maîtres d'ouvrage on certification across housing, tertiary and regional frameworks, and it also covers ecological expertise, acceptance measurements and EMC metrology. Wikidata records it as a French building diagnostics and regulatory measurement company — air tightness testing, ventilation, acoustics and energy performance — based in Aix-en-Provence and a subsidiary of the NORMAXIS group. The brand operates from Aix-en-Provence across five French regions: PACA, Occitanie, Nouvelle-Aquitaine, Auvergne-Rhône-Alpes and Île-de-France, and states that it has supported more than 500 operations.
