Studio 02 — LCA
The whole life, not just the carbon.
A life-cycle assessment for any product or system — concrete, a steel frame, a pump, a control board, a chemical process — aligned to ISO 14040/14044 and EN 15804+A2. Every module from product to end-of-life (A–D), eleven impact categories, life-cycle cost and circularity, not carbon alone. A deterministic engine computes every figure; AI writes the narrative and never touches the numbers. Export a report your client can audit line by line.
How it works
Assessment first. Prose second. Numbers stay computed.
Define goal, scope and functional unit
Set the study intent, system boundary and declared functional unit — say, one cubic metre of C30/37 at the gate. The engine models A1–A3 product, A4 transport to site, and a documented B use-phase estimate, so the boundary is explicit on the report.
Collect real data from suppliers
Send a shareable data-collection form to your cement and aggregate suppliers. Their figures flow straight into the inventory, and each material carries a pedigree score — verified EPD through literature proxy — that drives the reported uncertainty band.
Deterministic LCIA
The engine characterises impacts with EF 3.1, normalises against JRC 2021 person-year references, and runs contribution analysis by phase and by material. Missing emission factors are tracked as data gaps and reported as a lower bound — never silently zeroed.
AI writes the report around the figures
Parallel section writers draft Goal & Scope, Methodology, Hotspot Analysis, Comparative Interpretation and Recommendations. They interpret — they are barred from inventing numbers, so every figure in the prose traces to the deterministic engine.
Export a report that survives review
Ship a document with the characterised results, normalisation, pedigree-based uncertainty, per-material hotspots and the assumptions stated in full. Compare alternative mixes side by side to see which lever actually moves the carbon.
What's under the hood
Deterministic where it counts.
The math is auditable and repeatable. The writing is the only part an AI touches.
Impact model
Nine EF 3.1 midpoint categories, normalised to person-year equivalents, with an optional weighted single score.
Honest about gaps
A five-point pedigree matrix maps source quality to a documented ± band; the coverage-weighted mean sets the headline uncertainty.
Figures never invented
A router picks the register — academic, practitioner or executive — then section writers interpret the computed numbers under a strict no-figures rule.
The rest of the workbench
One subscription. Three more studios.
Compliant mixes in chat
Proportions to ACI 211, EN 206, TS 500 and BS 8500 with the exposure class resolved and a compliance checklist.
Open Mix Studio 03 — GeoField blows to parameters
