We identify the most relevant construction options, validate the technical and environmental data that documents them, then assess their impact on the project to inform the trade-offs and turn carbon ambitions into practical, measurable outcomes. The decisions with the greatest impact are made in the earliest stages, when the project's carbon trajectory can still be shaped, and this is where we come in.
We are TOTEM practitioners and carry out whole-building life cycle assessments. In direct contact with producers, we keep track of changes in product ranges, prices, and environmental and performance declarations for the materials we specify.
Preliminary design, sketch design, a specific technical question. We support the project team in identifying relevant materials and construction systems, according to the specifics of the project and the realities on the ground.

Explore the construction options that suit your project. A private session with one of our experts in our library of biobased and circular materials. Present a project, ask your technical questions, and turn your intuitions into clear choices.
One- or two-person practices · projects under 300 m² · individuals building or renovating. By appointment.
Service details
Assess the low-carbon potential of your project before design begins. A session at the Materatek with the project team to steer design choices. Identify the relevant options, compare the alternatives and set the ambitions.
Architects, engineering consultancies, clients and contractors brought together around a live project. Preparation and coordination included.
Service detailsBiobased, geobased, reclaimed and circular materials. We analyse build-ups and compare the alternatives on performance, carbon impact and cost, in a technical report.
Workshops of 2 to 3 hours with the project team in our materials library, to reach the best carbon performance for your project:
One workshop with the project team, and the technical report: strategy, materials, specifications and suppliers.
Two workshops, the technical report, and the Price & carbon analysis.
Two workshops, the technical report, the Price & carbon analysis and the TOTEM · LCA.
Three tiers to match the needs of the project · on-site consultation available on request during construction
Cost, embodied carbon, life cycle assessment. We establish the data needed to compare options, identify the real gains and prioritise the items that optimise the balance between cost and carbon.
A detailed comparison of your bill of quantities on price / carbon. You send it in any format; we match each item to its INIES code and cross-check it against our sources:
€500excl. VAT
Measure the environmental impact of your building. The life cycle assessment, from the production of materials to their end of life, carried out in TOTEM and officially recognised.
Service detailsReach the highest level of ambition on circularity and materials. We take on the client's role for the CIRC and MAT categories of the framework.
Service detailsQuantify the reusable value of your building before works begin. The inventory of the materials in place, their demountability, and the route each lot is directed to.
Service detailsBase your low-carbon strategy on data.
The framework behind all our recommendations, based on the guidance of the United Nations climate programme. The order is not arbitrary: a material that is never installed will always have a lower footprint than any substitute.
We favour renovation over demolition, and the preservation of what already exists. No built answer is needed when a passive or organisational approach is enough.
We replace conventional supply chains with biobased, geobased, low-carbon or reclaimed materials, wherever the intended use allows.
We work on the performance and service life of the building: assembly, reversibility, repairability and end of life.
Each level leads to a service. The reuse audit addresses the first, the price and carbon analysis and the project study address the second, and the life cycle assessment addresses the third.
