capabilities

Design lower-carbon buildings with automated construction LCA

One Click LCA's software combines automated life cycle assessment with the world’s largest construction LCA database, enabling faster and consistent carbon assessment across design and construction workflows.

Integrate with 20+ BIM, construction & energy modelling tools

Import material quantities and building data directly from BIM models, quantity take-offs, and energy models, or enter data manually. One Click LCA supports common tools and formats such as Autodesk Revit, Rhino, Procore, IFC, Excel, IES-VE, and energy models (gbXML). Input options also include building areas, energy and water usage, site operations, emissions, and removals for a comprehensive building LCA.

Access 500,000+ LCA datasets from verified sources

Work with the world’s largest construction LCA database, combining manufacturer EPDs, generic datasets, and private data. The database includes 500,000+ data points and allows quick access to material EPDs or generic data. It also enables users to benchmark materials and identify those with the lowest environmental impact.

Measure & reduce embodied carbon across all project stages

Quantify embodied, operational, and whole-life carbon from concept design using Carbon Designer 3D and BIM-based workflows. Compare design options, identify material and structural carbon hotspots, and track reductions across project stages to support informed design decisions and reporting.
