Volex Labs / Calculations / Structural embodied carbon calculator.

Structural embodied carbon calculator.

Enter the material quantities — concrete, reinforcement, steel, timber — and Volex Anvil computes the embodied carbon (A1-A5) using the ICE database factors, giving the total kgCO2e and the per-m² intensity you report to RICS WLCA and compare with the LETI and SCORS bands.

Embodied carbon is increasingly a design requirement, so the breakdown by material lets you see where the carbon is and test lower-carbon options against the same benchmarks.

Frequently asked

Which carbon factors?
The ICE (Inventory of Carbon & Energy) database factors for the A1-A3 product stage, extendable to A4-A5, reported to the RICS WLCA methodology.
How do I benchmark the result?
The per-m² intensity is compared with the LETI and SCORS rating bands so you can see how the structure performs and target a lower band.
Is it validated?
The total and per-m² carbon are checked against RICS WLCA worked figures — within 0.00%.
Free tier?
Yes — 10 calculations a month free; Pro (£29/month) adds unlimited runs and PDF calc sheets.
