Carbon figures calculated directly from your BIM model, not a spreadsheet estimate.
Whole-life carbon assessments built from spreadsheet takeoffs go stale the moment the design changes. We extract material quantities directly from the BIM model and map them to recognised embodied carbon factors, so the carbon figure updates as the design evolves rather than requiring a fresh manual calculation at every stage gate. The result is a number the design team can actually act on, not just report.
Discuss Your ProjectCarbon figures update automatically as the BIM model changes — no re-doing a spreadsheet takeoff.
Calculated to the RICS Professional Statement on whole-life carbon assessment.
Model material substitutions and structural options to see the carbon impact before committing.
Extract current design quantities from BIM and calculate baseline embodied carbon.
Compare against RIBA 2030 targets and comparable project data to size the gap.
Model material and structural alternatives to show carbon impact versus cost.
Re-run the assessment at each design stage so carbon stays visible through to construction.

Common questions about our Embodied Carbon Modelling service.
More accurate, in practice — manual takeoffs are a snapshot that quickly goes stale as the design changes, while BIM-derived quantities update automatically. The main accuracy driver is the quality of the underlying material carbon factors (ICE, EPDs), which we select and document transparently for every calculation.
Concept design (RIBA Stage 2) ideally, when structural and material decisions still have flexibility. We can also assess later-stage or existing designs, but the ability to influence the carbon figure through design changes narrows significantly once key decisions are locked in.
Our core focus is embodied carbon, but we work alongside building services engineers on operational carbon so clients get a genuine whole-life carbon picture rather than an embodied-only figure that ignores in-use energy performance.
Yes — this is one of the most valuable parts of the service. We model design alternatives (e.g. timber versus concrete frame, low-carbon versus standard concrete mix) directly against the BIM model, so the design team sees the carbon and cost tradeoff before finalising a decision.
Primarily the ICE (Inventory of Carbon and Energy) database and manufacturer-specific Environmental Product Declarations (EPDs) where available, since EPDs give a more accurate product-specific figure than generic database averages.
