Architects & prescribers
A technical partner in design

An architectural practice entering the French market meets a regulatory framework that differs from the British or North American one on a point of principle: several requirements are verified by a third party accredited by the State, not self-declared and not checked by the design team. Deciding late who carries that verification is the single most common cause of delay we see on cross-border projects.

Three requirements shape the design phase. RE2020 sets a carbon budget over the building's whole life, which makes the life-cycle assessment a design input rather than a compliance document produced at the end. Acoustic regulation fixes measured performance on the finished building, so an assumption made at competition stage is tested on site two years later. And where the site carries ecological value, the avoid-reduce-offset sequence conditions the planning permission itself.

The carbon thresholds tighten on a published schedule. A structural choice made without a life-cycle model has a fair chance of missing the threshold in force at delivery, and the corrective options at that stage are expensive: change the structural material, change the envelope, or negotiate. Running the assessment during the competition costs a fraction of that, and it produces an argument the jury can read.

The same logic applies to acoustics. French regulation is expressed in measured values on the delivered building, which means the design commits the project to a result that will be verified. Our regulatory acoustic compliance work exists to close that gap between the calculation and the measurement.

NORMAXIS holds both engineering and certification activities, in separate legal entities, and that separation is not presentational. ARKEMEP and ARKENOR work alongside the design team. IRICE, the group's certification body, is accredited by Cofrac under ISO/IEC 17065 (accreditation no. 5-0655) and assesses projects as an independent third party. IRICE never certifies a project on which the group provided design assistance in a way that would compromise impartiality, and the accreditation is what makes that statement auditable rather than promotional.

For an international practice this matters at a practical level: a client asking for an environmental claim to be defensible under EU Directive 2024/825 needs verification by someone who did not produce the design. Understanding which of your partners can play that role, and which cannot, avoids discovering the conflict at the point of publication.

Most engagements start at competition stage, where the questions are open and the cost of an answer is low: an early carbon model, an acoustic risk read of the site, an ecological pre-diagnosis telling you whether a protected-species derogation is likely. From there the work follows the design phases, and the deliverables are the ones the French permitting process expects, in the format it expects.

Where a project pursues biodiversity certification, the design assistance and the certification are contracted separately, with different entities, precisely so that the certificate keeps its value.
