The cove.tool plugin exports the basic building geometry from your Rhino model, uploads it to an existing cove.tool project, and reports the Energy Use Intensity (EUI) breakdown. Cove.tool licenses are free for students, researchers, and educators (non-commercial work only). Please contact with an .edu email address to get free access. Rhino 5 and 6 compatible. 

Version 3.0.0 Updates!

  • Auto-detect Single-Use and Mixed-Use projects (NEW).
  • Auto-create cove.tool layers (NEW).
  • Reference geometry from cove.tool layers (NEW).
  • Simplified user controls to three interactive buttons/toggle switches (NEW).
  • Auto-assign and reference geometry per building types for mixed-use projects (NEW).
  • Auto-find cove.tool projects through text search using the project URL.
  • Added an area threshold to remove surfaces under 1 s.f.
  • Fixed small bugs for more accurate and faster solution time.
  • Auto-calculate the building height.
  • Simplified user instructions and feedback panels.

Installation (Rhino 6) Download and run! You will need to install the latest version of IronPython found here: IronPython. Download the .msi installer and run. See here for a walkthrough: IronPython Step by step install

Installation (Rhino 5):

  1. Download and install GhPython
  2. Download and extract the latest version of the to a location you will remember on your hard drive

Usage - at covetool.comcovetoolgrasshopper

  1. Sign up for an account.
  2. Create a new project.
  3. Copy the URL address from the project page.
  4. Fill out the project information details, and click the Save & Continue button to advance to the Building Geometry page (this is what the plugin will export).
  5. Switch over to Rhino.

Usage - in Rhino:

  1. Open your model and Grasshopper.
  2. Open the file and follow the instructions in the definition.
    1. Step 1 – Provide your login, password, and paste the URL from the project page in the text panels.
    2. Step 2 – Verify the correct project is selected. If not, double-check that your login and password are correct and recalculate or press F5.
    3. Step 3 – Once your project is connected, follow the instructions in Step 3 to automatically create the appropriate cove.tool layers, and move the building geometry onto the associated cove.tool layers. Then you will be able to reference that geometry and export the energy values and geometry to cove.tool.
  3. Return to the Building Geometry page for your cove.tool project and refresh the page. The appropriate area fields will now be populated and you can select 3D Mode to continue with the next steps.
