CategoryWhole life carbon & early LCALife cycle assessment & EPDs
AI role (our label)Not AI-firstAI features added to established product
What it doesWhole life carbon and embodied-carbon modeling platform for building design: early assessments from six basic inputs before BIM, detailed assembly and EPD-based modeling, portfolio benchmarking, low-carbon product search, and reporting exports (including to AIA 2030 DDx). Also offers Tally 2.0 for real-time LCA inside Autodesk Revit and a Whole Life Carbon API. Vendor says it is used by 300+ design and engineering firms and cites assessments on 800M+ SF GFA (vendor claims). FAQ says a preliminary assessment takes less than 30 minutes and a more detailed one a few hours. About page vision statement mentions "AI-enabled decisions"; product pages we read do not describe AI features, so we tag it Not AI-first.Life cycle assessment and EPD software for construction and manufacturing: run LCAs from BIM, Excel, or bills of quantities, compare design options, prove compliance, and generate EPDs. Its Powered by AI page describes AI-driven data integration and AI mapping that matches materials across synonyms, spelling differences, and languages (vendor claim of "ten times better data mapping"), plus AI-powered insights that verify results, suggest improvements, and compare designs against projected performance. Carbon Designer 3D supports early embodied-carbon LCAs without a BIM model; the Power Pack plan lists Generative Design in Carbon Designer 3D and other AI enhancements. Vendor cites 500,000+ LCA datasets, compliance with BREEAM, LEED, DGNB, and 140+ other schemes, 20+ BIM and simulation integrations (including Autodesk Construction Cloud, Takeoff, and Procore), and ISO 27001 / SOC 2 certification (vendor claims).
Who it's forArchitects, engineers, and building product manufacturers; also used in university coursework (vendor statement).Architects, engineers, contractors, developers, consultants, and construction product manufacturers.
Pricing (as publicly stated)Free for individuals and firms to model unlimited projects for embodied and operational emissions; vendor says you pay when ready for detailed assessments or compliance reporting. EDU accounts always free. No dollar prices on the pages we read. (Checked Oct 15, 2026.)Not publicly listed for Designer, Expert Pack, and Power Pack (each routes to request a quote). Power Pack is the tier One Click LCA lists with "AI enhancements" and Generative Design in Carbon Designer 3D. A separate Business License is sold online for standard compliance and certification LCAs (named or concurrent user licenses); no dollar prices appear on the design-and-construction pricing page.
