What do you need to do to Comply?

OEESC Compliance COMcheck

The COMcheck software/program, using the Oregon code selection, is used to demonstrate compliance with the 2014 OEESC. The forms generated by the software can be submitted for demonstration of compliance 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).

3 ways to demonstrate compliance with 2014 OEESC:

  1. Prescriptive Path
    Complete and submit COMcheck forms to local jurisdiction
  2. Simplified Trade-Off
    Complete and submit COMcheck forms to local jurisdiction
  3. Whole Building Approach (WBA)
    Instruction on using Whole building approach (WBA) to demonstrate compliance with 2014 OEESC

Beginning Instructions for COMcheck. See the Additional Resources links below for complete instructions and help:

  • Download latest version of COMcheck at energycodes.gov. Select operating system, either Windows, Mac, or Linux
  • Select a "New Project" or open a saved file
  • Select "Oregon" from the Code pull-down menu (under the State Codes section)
  • Select your Project Type (new construction, addition or alteration)
  • Use the Project Details Notes as needed to clarify project details (non-typical conditions, separate application for Envelope, Lighting or Mechanical)

COMcheck is available for use in online format at COMcheck*Web.

Additional Resources (Not Oregon-specific)

  • COMcheck Basics - Additional Video Training
  • COMcheck Software Support Guide
  • Resource Guide for Code Officials
    This site has general information regarding what submissions should look like, what to look for on plans. This site is for basic COMcheck (not Oregon-specific; Note that Residential/REScheck information does not apply). A good resource on Chapter 5 for designers and code officials. Note: a direct link to the Resource Guide is not furnished here, as it is a large file size PDF. The above link points to the page where the large size PDF is available for download.
  • Ductwork Insulation Guide
    Figure 1 (page 2) provides guidance for what ducts receive insulation or not and whether the duct is in unconditioned space (R-5: Items 3, 5, 6, 13, 14; items 9, 10, 11 if not meeting Section 503.2.7, Exception 2) or exterior to the building (R-8: Item 4).
