Speckle is how 3D geometry reaches Real-Time LCA. You publish from Revit, ArchiCAD, Rhino, or Grasshopper, and the elements — with their materials, quantities, and classification codes — appear on the project’s Materials page ready for mapping. There are two things to set up, and they are separate: your Speckle account, once per user, and a connection, once per project. Your Real-Time LCA user has its own Speckle account. Open it from the account menu → Integrations → Speckle.

Before an account is linked

Create Speckle account asks you to choose a password for the new account — you sign in to Speckle with your Real-Time LCA email and that password. Once it exists, the dialog shows the account as connected.

A linked account

Note the server address shown in this dialog. You sign the connector in to that server, not to the public Speckle server it offers by default.

2. Connect the project

Open the project’s Settings → Integrations → Speckle → Configure.
Configure Speckle page offering a new connection or a shared connection, with a four-step explanation of how the model gets in.

Configuring a project's Speckle connection

Once connected, the Integrations section reports the models in sync, when they were last published, and offers Sync now.

3. Publish from your tool

1

Install the connector

Download it from the Speckle settings dialog, or from your tool’s own plugin manager.
2

Sign in to the server

In the connector, sign in with the Speckle account linked to your Real-Time LCA login — and to the server address from step 1.
3

Publish the model

Create or share a connection first; the stream to publish to appears once it exists.
4

Map the materials

The model’s materials appear in Material Mapping. Publish again after a design change and the inventory updates.

Revit

Step-by-step publishing from Revit.

ArchiCAD

Publishing from ArchiCAD.

Rhino

Publishing from Rhino.

Grasshopper

The Real-Time LCA plugin for Grasshopper.

No model yet?

You do not have to wait for geometry. Enter building elements by hand, import them from Excel, or load the sample set — a model can be connected later without losing that work.
