Building Transparency has announced the development of Tally® 2.0 in partnership with KieranTimberlake. This updated version of the LCA tool aims to enhance the building industry’s capacity to evaluate and reduce the environmental impacts of materials and design choices.

The original Tally tool was launched in 2013 by KieranTimberlake, who began developing the tool in 2008. In 2021, we included Tally as part of our deep dive into the various climate-orientated architecture software systems developed by architects and designers.

Tally was the first LCA application allowing designers to assess the environmental footprint of projects within Revit. It has since been adopted by nearly 3,500 users in the architecture, engineering, and construction.

Building upon the success of its predecessor, Tally 2.0 will introduce new features that promote informed, carbon-conscious decision-making. Planned updates include interactive reporting, adherence to industry standards, and user interface enhancements to improve LCA modeling.

“Our mission at Building Transparency is centered around providing the tools and resources needed to drive embodied carbon reductions in the building industry,” said Stacy Smedley, Executive Director of Building Transparency. “With Tally 2.0, we are continuing this commitment by giving a major update to a tool that we know is working well but can be further improved to support our users. We're grateful for KieranTimberlake's support and partnership in developing this next version of our life cycle assessment tool.”

Currently in development, Tally 2.0 is expected to launch publicly in 2025.
