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 "New Project" 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 about the automated mapping.

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



Ribbon/Toolbar Icon Command Command Description

New Project

In a 3D view, launch the command and all visible or selected elements will be added into a new Carbo Life Project. Its embodied carbon will be calculated and presented. From here you can use all the tools available to evaluate or optimize the carbon footprint of the building

Update Project

Use this command to update a previously exported project. Open a Carbon Life Project file and it will update all the elements and their volumes.

Export Settings

To access advanced export settings, use this command. This allows the export of existing or demolished elements. It also gives control of the export categories and from which level the app defines the substructure. (These settings are in Beta, and will improve in the future)

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 excel' option to use the data and create visualizations as required.
