Carbo Life Calculator

Carbo Life Calculator

Win64, English

David Veld
A Quick-Action Carbon Embodied Carbon (LCA) calculator. It's open-source & free.

General Usage Instructions

In a 3D view launch CarboLifeCalc, by using the "Launch" command. Carbo Life Calc will now transport all the visible elements (or just a selection) to the calculator.

1. The Autodesk® Revit® materials will be mapped to CarboLifeCalc's based on the closest match. This will result in an instant embodied carbon calculation.

2. On the "Calculation" tap you can now view and edit the calculation. Use conversions, waste, and other factors to fine-tune the calculation results. 

3. Under "Group" -> "Map Materials" you can change the materials if you are unhappy with the automated mapping.

4. Use the material editor to assess how your material factors are calculated, you can also rename your materials closer to your Revit materials, this allows future exports to run smoother


Ribbon/Toolbar Icon Command Command Description


In a 3D view, start the "launch" command. A dialog box will ask you how to proceed. As a default all visible or selected elements will be used to create a new Carbo Life Project. Its carbon footprint will directly be calculated and presented. Once the app initiates the user can use all the tools available to evaluate or optimize the carbon footprint of the building


Use this command to show your embodied carbon data in a 3D Revit View. After launching the command: select a saved Carbo Life Project and the dialog will allow the user to visualise the project in various ways.


The installer that ran when you downloaded this app/plug-in from the Autodesk App Store will start installing the app/plug-in. OR, simply double-click the downloaded installer to install the app/plugin.

NOTE: Please uninstall the older version of the app before installing the newer version.

NOTE: If your material database was stored at the default installation path, you risk overwriting and losing your materials when you update. Please backup your user files before updating, or uninstalling this app.

To uninstall this plug-in, exit the Autodesk product if you are currently running it, simply rerun the installer, and select the "Uninstall" button. OR, click Control Panel > Programs > Programs and Features (Windows 7/8.1/10/11) and uninstall as you would any other application from your system.

Known Issues

Merging groups and isolating Revit elements from a group does not always work. (a feature that isn't often used)

The graph functions are limited, and pie chart values can sometimes overlap, please use the 'export to csv' option to use the data and create visualizations as required.

Version History

Version Number Version Description


This is the first major update for Revit up to 2024. Many updates. Re-designed visualisation dialog. Data aligned to IstructE values, sequestration and grouping options, Leti chart, improved report, and cvs export added.


This is the first release. A stable and useful application with all features, while still in need of a few polished edges.
