COMcheck
The COMcheck software/program, using the Oregon code selection, is used to demonstrate compliance with the OEESC. The forms generated by the software can be submitted for both the Prescriptive and Simplified Trade-Off paths. Under the WBA path, Simplified Trade-off forms should be included to demonstrate the differences between the design building and a compliant building. Forms may be submitted electronically (verify with your jurisdiction).
Demonstrate compliance through the following:
- Prescriptive Path: complete and submit COMcheck forms to the local jurisdiction
- Simplified Trade-off: complete and submit COMcheck forms to the local jurisdiction
- Whole Building Approach (WBA) Instructions
