TallyLCA

Integrated Environmental Assessment for Material Choices
Carbon Accounting
TallyLCA (also called tally) is a whole-building life cycle assessment (LCA) tool integrated into Autodesk Revit that helps architects, engineers, and design teams quantify the environmental impacts of building material choices during design rather than post-construction. It links BIM element quantities to a curated life-cycle materials database to deliver impact data in real time within the design workflow. Tally supports evaluation of embodied carbon and other impacts and enables side-by-side comparisons of design options, helping teams understand trade-offs and make data-informed sustainability decisions early in project development.
