Bim-driven Whole Buiilding lca
Tally 2.0 is here,
and smoother than ever.
We've rebuilt Tally from the bottom up to use newer data, an expanded library of takeoff methods, and to lessen the burden and increase the accuracy of BIM-based life cycle assessment.



Give Yourself the whole picture
Material impact assessment integrated directly in your BIM environment.
Track materials and impact data holistically as you model, sync'ing your choices from the model directly to the firm-wide portfolio and back again
Get answers fast
With Tally 2.0, there's no more waiting to complete the analysis before running the report. Results are generated as you design, connected directly to the elements in the model.
Tally 2.0 handles linked models and standalone models with equal ease, allowing multiple paths to better collaboration across the project team.


New data, better methods
The impact and supply chain data within Tally 2.0 has been totally rebuilt to bring the tool up to date with current practices. This data update will allow users to use product-specific EPDs within the calculation.
"Tally 2.0 strengthens data continuity from early design through construction by putting credible, trackable data within reach for more teams and more projects."
