Engineering · Expertise · Certification
In 1752, in the southern hemisphere, the astronomer Nicolas-Louis de Lacaille catalogued a constellation no one had named before. He drew it between Scorpio and Centaurus, away from the great mythological figures, and gave it the name of two instruments — the square and the rule — brought together under a single word: Norma. The norm that aligns.
No blazing star. No noisy figure. The tool that verifies that the angle is right, that the vertical holds, that the structure aligns. The instrument of those who build, away from the narratives.
Two and a half centuries later, the construction-site squares have given way to thermal calculations, carbon simulations, independent third-party certifications. But the discipline has not changed: a building holds because it has been measured, verified, signed.
In the name NORMAXIS, several dimensions stack up. The norm that binds. The north that orients. Norma that aligns. Max that sets the threshold. The axis that holds the load. Five interlocking readings. A single discipline.
NORMAXIS places building engineering in this lineage. ARKEMEP fuses energy. ARKENOR goes beyond compliance. IRICE grows life and certifies it as an independent third party. Three trades that share a single rigour: Engineering. Expertise. Certification.
A building is not a promise. It is an architecture that aligns, verifies and is signed — and that holds over time.
Building the reference.
NORMAXIS practice
Engineering · Expertise · Certification
Three trades that share a single discipline — measuring, verifying, signing.
Engineering
We size projects against the rules that bind them. Every assumption is citable, every calculation tied to its standard, every choice aligned with a recognised method.
Expertise
We measure on site what was designed on screen. Air infiltrometry, acoustics, ventilation, biodiversity: expertise verifies that reality matches intent. Verify before validating. Measure before declaring.
Certification
In a world where everyone produces calculations, court-admissible evidence becomes the rare asset. IRICE, a group subsidiary, signs as an independent third party under ISO/IEC 17065.
Doctrine
Our doctrine on artificial intelligence.
Artificial intelligence is starting to enter building engineering. Assistive tools for thermal modelling, acoustic optimisation or MEP pre-sizing are appearing — as auxiliaries, still immature, to be watched.
At NORMAXIS, calculations are performed by engineers. Fully. RE2020 thermal studies (France's environmental regulation for buildings), dynamic simulations, carbon LCAs, HVAC sizing, predictive acoustics: every result carries the responsibility of a professional who set it down, interpreted it, signed it. AI may become a complementary tool in the coming years — we observe it, test it, prepare for it. But today the value of a study is measured by the human competence that produced it.
What AI will never do, however mature it becomes: place a sound level meter on a floor for an NF EN ISO 16283 acceptance. Sign a court-admissible RE2020 air-tightness test. Carry responsibility before a judicial expert. Deliver an ISO/IEC 17065 certification on site.
The NORMAXIS discipline is also that: distinguishing what can be assisted from what must remain human. Measure, verify, sign — three acts our engineers perform themselves, today as tomorrow.
Group architecture
Three trades. Three geometries. One architecture.

Three proprietary tools
What the group has built.
Three tools developed by NORMAXIS — a certification framework, a diagnostic method, a measurement instrument — that did not exist before. Operated today as a third party by IRICE. This is what sets the group apart from a simple aggregation of engineering offices, consultants and advisory firms.
Certification framework
Biodiversity of real-estate operations
The group's proprietary framework in four versions — NCO 25.05 (new construction), EVO 25.05 (renovation), HOR 25.05 (urban development) and HVE (operation follow-up). A certification, not a label: operated as an independent third party under ISO/IEC 17065 by IRICE.
effinature.fr
Diagnostic method
Biodiversity Performance Score
The group's proprietary method — 70+ criteria across three phases (baseline, design, operation). Covers CSRD, SFDR Art. 8-9, EU Taxonomy DNSH, ZAN (France's Net Zero Land Take). A rating tool distinct from any certification — individual IRICE attestation, consolidable at portfolio scale.
diagnostic-biodiversite.frEfficarbone
Measurement instrument
Construction-site carbon measurement and rating
The group's proprietary instrument for measuring carbon emissions on construction sites, aligned with ISO 14044. Traceable data, comparable across projects and phases.
Institutional evidence

Headquarters in Aix-en-Provence. Our engineers travel on site across three major regions of South-West France — because measurement cannot be delegated, and physical evidence comes from the ground, not from a screen.
