Getting Started
COMcheck-Web™ is accessible directly from the website without having to download and install. COMcheck-Web is currently maintained in two versions: Legacy COMcheck and a new version of COMcheck-Web. COMcheck-Web now runs on Amazon Web Service (AWS), enhancing stability, security, and performance to provide a faster and more reliable user experience.
The new version of COMcheck-Web supports commercial and high-rise residential energy code compliance while providing better user navigation and experience. All future national or state energy codes will be implemented in the new version of COMcheck-Web.
Note: To login to the New COMcheck-Web application, a new login account must be set up with a valid email address from the login screen!
Commercial Compliance Using COMcheck™
The COMcheck software product group makes it easy for architects, builders, designers, and contractors to determine whether new commercial or high-rise residential buildings, additions, and alterations meet the requirements of the IECC and ASHRAE Standard 90.1, as well as state-amended and state-specific codes. COMcheck also simplifies compliance for building officials, plan checkers, and inspectors by allowing them to quickly determine if a building project meets the code.
