COMcheck is the U.S. Department of Energy (DOE)’s commercial energy compliance tool that essentially tells a user whether or not a building meets the requirements of the International Energy Conservation Code (IECC) and ASHRAE 90.1, as well as state-specific codes. COMcheck is a software that can be downloaded for Windows® and Mac® and it supports the 2006, 2009 and 2012 IECC as well as ASHRAE Standard 90.1: 2004, 2007 and 2010, and various state codes.

COMcheck is a performance method, which means that it provides the building’s overall performance requirement and replaces the individual prescriptive requirements for building envelopes and assemblies. Builders often prefer the performance method over the prescriptive, as it allows more flexibility with the building envelope.

Who uses COMcheck?

General contractors, lighting contractors, mechanical contractors, architects, specifiers and many other construction industry professionals utilize COMcheck. Many states require a COMcheck report before a building permit is even issued, so oftentimes builders must utilize the software to find the building code requirements for their state. Architects and lighting and mechanical engineers can run the Interior/Exterior Lighting and Mechanicals (HVAC) sections of COMcheck to ensure that what they specify meets commercial building energy codes. Other sections, such as “Envelope”, are pertinent to insulation manufacturers and suppliers.

My Advice

Although this may seem obvious, it’s important to remember that a building must be constructed exactly to what’s specified in the COMcheck report, as there may be a final inspection of the building after the report has been issued. If there are discrepancies between the report and what has been installed, you may be required to fully redo the install.

COMcheck is an extremely useful tool for metal building construction industry professionals. While it is helpful, it can also be overwhelming. Therm-All representatives undergo extensive training in COMcheck and are able to provide you with a custom COMcheck-based solution for your next job.
