The Tally Climate Action Tool (tallyCAT) gives you a fully functioning Embodied Carbon in Construction Calculator (EC3) inside your Autodesk® Revit® project.  

• Upload material types and quantities to EC3 from Revit.
• Use powerful estimation tools to get takeoffs in the units required by Environmental Product Declarations (EPDs)
• Evaluate climate impact and savings opportunities based on over 100K verified EPDs for real products.
• Use rich interactive graphs and heatmaps to understand the areas of greatest impact and savings potential in the design.
• Annotate takeoff equations and GWP intensity back to the .rvt file for use in other designs and future versions. 
• Save, share, and compare Revit families in a library of EC3-annotated components.  
• Create custom reports for Buy Clean policies, LEED, and ICMS.

Note: This app uses a custom installer (and not the standard App Store installer).
