Prerequisites & Import Options

A user can use the plugin, but to utilise exported data, they have the following options:

Option 1. Upload data directly to own One Click LCA project.

This requires user having an appropriate active commercial or trial One Click LCA license and an appropriate project on One Click LCA. For this, ensure you have a private project in One Click LCA before starting the import process. See how to create a project in One Click LCA here. See the license requirements for importing data here. See how to get a free trial version

Option 2. Send data to another user to upload to One Click LCA.

This requires the other user to have an appropriate license. See more info on this process here.

Watch our tutorial video of the tool's basic functionalities and test the web interface to explore how the tool works before working in the plug-in and exporting the model to the web interface.

• Step 1: Open your project on Revit

To be able to isolate objects in the Revit model using One Click LCA Add-in, please make sure that you are in 3D view. The view can be selected by navigating to the View tab and pressing on “3D view” as seen in the screenshot.

• Step 2: Click “LCA in Cloud” or “LCA in Revit”.

“LCA in Cloud”: Exports quantities directly with default settings.

“LCA in Revit”: Allows editing plugin settings and starting your work inside Revit before exporting, or to work purely inside Revit.

• Step 3: If chosen “LCA in Revit”, start by reviewing the settings.

In this tab, you can select Scope, define used and exported Revit parameters, and most importantly decide if you wish to split objects (families) into materials or not. For a less detailed model, It is strongly suggested that you select to not split the objects and instead use the whole objects and their area and map them to constructions or EPDs that represent composite products (eg external walls or slabs)

• Step 4: Review and adjust Model and Categories tabs 

In the Model tab, you can define the phases and linked models that shall be accounted for in the assessment. The current phase is selected by default, and the selection allows only one phase at a time to avoid duplicate materials exporting. If you use a linked model, please make sure it is defined which model is chosen, and select or de-select models if needed.

In the Categories tab, you can further adjust for each individual object whether it shall be included in the assessment or not, if it shall be broken down to materials or kept as a composite object, and last, what shall be the default units for each building part or object.

• Step 5: Review materials and start mapping them in the Materials tab.

To generate automated mappings inside the plugin (Expert feature), users need to first log in (at the Login tab) and then navigate to the Results tab.

Mapping can be also done in the web interface, after the export.

The updated material list and most updated choices for mappings in the plugin can be exported at any time by clicking the “LCA in Cloud” button inside the plugin.

Remember that you can use the “Isolate Materials” feature to understand which Revit element is each material row referring to.

Show “LCA profile” feature enables you to see the details of the selected environmental profile (need to be logged in).

Please mind that in the online interface some mappings might change depending on the tool that you select to import the data to, and the allowed data for that specific tool.

• Step 6: Generate results

See Results and Graphics to analyze your design carbon impacts (Expert features).

• Step 7: Export your model data

Click 'LCA in Cloud' to export your model to the One Click LCA web interface.

• Step 8: Follow general import guidance
