Tutorials - Getting Started with CBECC-Com v3

To get started with CBECC-Com a series of tutorials has been developed to help users understand the software workflow. The development of the tutorials has been funded by Southern California Edison (SCE) and other IOU's in the State of California.

The tutorials will help users understand the two different modeling methodology that can be used to create building geometry - Detailed Geometry approach and Simplified Geometry approach for compliance modeling with CBECC-Com.

The key difference between the two approaches is that the Detailed Geometry approach requires the user to draw the building and all its elements using a drawing tool, in this case SketchUp with the OpenStudio plug-in. This approach accurately represents a building and its elements in three-dimensional (3D) form. Spatial relationships and properties of the building surfaces such as areas, orientation and tilt are accurately represented in the 3D drawings. The additional software required for using the Detailed approach can be downloaded from the software page. The Simplified Geometry approach on the other hand defines the properties (areas, orientation, tilt, etc.) of the building surfaces within the CBECC-Com interface, but the spatial relationship between surfaces is not defined.

A series of tutorial files have also been provided to illustrate and help users work along using the two modeling approaches.

Tutorial Videos

A series of short tutorial videos have been developed to help users understand the software workflow, and specific features as identified below. The videos provide step by step procedures for modeling tasks using examples. [Right-click on the desired format to download the video or click on the title to view the video in the browser]

Note: The videos were created on an earlier version of CBECC-Com (v1c) so the user interface in the videos may not match the user interface of the current version of CBECC-Com. The intent of the videos is to provide guidance on the modeling workflow using SketchUp/OpenStudio and CBECC-Com.
