Washington State 501c(3) nonprofit Building Transparency and architecture and design firm KieranTimberlake have announced that an updated version of the tallyLCA software tool is under development, for release in 2025.
Like its predecessor, Tally 2.0 will remain an open-access, life cycle assessment app that enables architects and designers to calculate the carbon impact of manufactured building products and materials, and compare designs while working on Revit models in real time.
What is tallyLCA?
Life cycle assessments (LCAs) are an integral part of the contemporary AEC process, providing data on the environmental impact of building materials and products for consideration during the planning process.
As a refresher, the process for conducting life cycle assessments (LCA) is outlined in the ISO14040 standards and measures a product’s inputs, outputs, and environmental impacts throughout its lifespan—whether cradle-to-cradle or cradle-to-grave. LCAs provide necessary data for architects and designers to compare similar products within a specific category.
In its earliest iterations, tallyLCA was conceived by KieranTimberlake subsidiary KT Innovations to bridge the gap between the Building Information Modeling (BIM) process for whole-building designs and the need to utilize LCA data earlier in design phases so the carbon impact of a specific bill of materials could be determined. More than 3,000 AEC professionals currently use the tool to calculate environmental footprint in Revit.
