Design greener. Prove it with numbers.
Methvin embeds carbon accounting, embodied emissions tracking and green-rating evidence directly into your estimate, BIM model, project programme and cost plan — so sustainability targets are met by design, not reported after the fact.
Why Methvin for Sustainability
Four ways Methvin helps project teams meet green ratings, track embodied carbon and control the cost of sustainable design — from concept through construction.
Embodied carbon quantified at tender stage
Attach carbon factors to estimate line items and quantify embodied emissions per material, package and design option. Compare low-carbon alternatives against their cost premium before a single material is ordered.
BIM model as your carbon data source
Map BIM model elements to material carbon factors. Quantity changes in the model automatically update the carbon schedule — keeping embodied emissions calculations current as design evolves across every discipline.
Green-rating credit tracking in the programme
Manage Green Star, NABERS, BREEAM and WELL credit requirements as project tasks with evidence attachments, responsible parties and due dates — integrated into the construction programme so credits are never missed.
Sustainable design cost delta, visible in real time
Track the incremental cost of every sustainability initiative against the base-case estimate. Present clients with a clear cost-vs-carbon trade-off at any stage of design — backed by live BOQ data, not assumptions.
Tools that make sustainability measurable
Each module contributes a distinct layer of sustainability data — and they share it with each other in real time.
Estimating
Assign embodied carbon factors (kgCO₂e/unit) to every estimate line item. Model low-carbon material substitutions and surface the cost-vs-carbon trade-off within the BOQ — before design is frozen.
Learn more →BIM
Link IFC model elements to material carbon databases. As designers revise geometry and specifications, the federated model recalculates embodied carbon automatically — no manual re-entry between disciplines.
Learn more →Project Management
Track Green Star, NABERS, BREEAM and WELL credit obligations as programme tasks. Assign credit champions, upload evidence documentation and monitor submission deadlines alongside the construction schedule.
Learn more →Job Costing
Separate sustainable-design cost premiums from base-contract costs in real time. Track green-material procurement spend, renewable energy installation costs and waste diversion expenses against the sustainability budget line.

Sustainability targets set in the design brief are routinely eroded by value engineering. Methvin makes the carbon and cost impact of every design decision visible before it's made.
- Embodied carbon calculated per design option at tender — not back-calculated at handover
- Low-carbon material substitutions priced and carbon-quantified simultaneously in the BOQ
- Green-rating credit evidence linked directly to the programme task that generates it
- Whole-life carbon projections updated automatically as the BIM model evolves
- Sustainability premium costs isolated from base contract for transparent client reporting
What sustainability-focused teams say
Reviews from sustainability managers, estimators and BIM coordinators delivering green-rated projects with Methvin.
“We used to do embodied carbon calculations in a separate spreadsheet, weeks after the estimate was issued. Methvin made carbon a live field in the BOQ. Our design team can now see the carbon impact of a spec change before approving it.”
“Linking BIM model elements to carbon factors transformed our Green Star submissions. Evidence was captured as we built, not scrambled together in the final month. We achieved 5 Stars on our first submission — no resubmission needed.”
“Our client asked for a cost-vs-carbon trade-off analysis during design development. We pulled it directly from Methvin in 20 minutes. That kind of real-time transparency is what wins repeat commissions from sustainability-conscious clients”
Frequently asked questions
Common questions from sustainability managers, estimators and BIM teams evaluating Methvin for green-rated project delivery.
How does Methvin handle embodied carbon rate data?
Methvin supports user-configurable carbon factor libraries, allowing teams to apply factors from ICE Database, EC3, EPD data or client-specified sources. Factors are assigned at the material or rate-item level within the estimate, and can be updated as new EPD data becomes available.
How does the BIM module connect to embodied carbon tracking?
Model elements in the IFC file are mapped to material specifications and their associated carbon factors within Methvin. When a designer changes the concrete specification or structural steel grade, the carbon schedule recalculates automatically — without re-exporting from the BIM authoring tool.
Which green-rating schemes does Methvin's project management module support?
The credit register within Methvin's project management module is fully configurable to any rating scheme including Green Star, NABERS, BREEAM, LEED, WELL and Living Building Challenge. Credit categories, point targets, evidence requirements and submission deadlines are all configurable to the specific scheme version.
Can we compare two design options on both cost and carbon in the same estimate?
Yes. Methvin's estimating module supports design option scenarios within a single BOQ. Each option displays both the cost delta and the embodied carbon delta side by side — enabling your team and client to make an informed decision based on both financial and environmental impact simultaneously.
How does job costing help manage the sustainability budget separately from the base contract?
In Methvin's job costing module, sustainability initiatives — such as low-carbon concrete premiums, renewable energy systems, waste diversion and green-certification fees — are coded to a dedicated sustainability cost centre. This isolates green-initiative spend from base-contract costs, making client reporting and funding claims straightforward.
Can Methvin support whole-of-life carbon reporting, not just embodied carbon at construction?
Methvin's BIM and estimating modules support Modules A (product and construction), B (operational) and C (end-of-life) carbon inputs aligned with EN 15978 / ISO 21931 whole-life carbon assessment frameworks. Operational carbon assumptions from energy modelling can be imported and reported alongside embodied carbon in a unified project carbon summary.
Make every design decision a sustainable one.
Embed carbon accounting into your estimate, BIM model, project programme and job cost plan — and deliver green-rated projects with the evidence to prove it.
