Common Reasons a Comcheck Fails and How to Avoid Them
Today on the Comcheck Energy Report Blog by www.Comcheck.net we are going to discuss the reasons that a Comcheck might fail. On an everyday basis, we work with all types of Comchecks. We always run across some Comcheck reports that fail. We also run across users of Comcheck Web, Comcheck Desktop, and New Comcheck that have generated a Comcheck Energy report PDF and cannot figure out why it is failing. Follow along as we show the most common reasons for a Comcheck failure, and how to avoid it completely.
U Values: Your glazed windows and doors will need to meet certain efficiency criteria if you are installing them new on a construction, alteration, or addition type Comcheck. In Comcheck software the efficiency of a window is measured in U Value. Different states have different rules as to the maximum U Value that your windows and glazed doors can have taken as an average. If your U Value average exceeds this preset limit then your project will autmatically fail. Sometimes the U value failure can be as simple as you missed a decimal place in your data.
For example: a .29 window is accidentally entered into Comcheck Web as 2.9 U value. The maximum allowable U value for the location of construction is .35. Since 2.9 is greater than the maximum allowable value of .35 U value then Comcheck Web will generate a failing score and report.
Another example: The windows you chose are .4 U value. The maximum allowable U value for the location of construction is .35. Since .4 U value is greater than the maximum allowable value of .35 U value then Comcheck Web will generate a failing score and report.
Choosing the correct windows and doors is very critical in Comcheck reporting and the U value of components help make sure that your Comcheck will pass without failure.
Comcheck Energy Report: What to Expect
SHGC: This is the solar heat gain coefficient. Each state also has a maximum SHGC that the glazed windows and doors can have. A common threshold in southern states where SHGC is mandated is .25 although it differs state to state. If your windows or doors have an average SHGC that is above the required level in Comcheck Web, Comcheck Desktop, or New Comcheck then the project will automatically fail.
Energy Code: Comcheck has alot of different energy codes that can be used on every project. You can even toggle in and out of some energy codes to see how the project would fair under different criteria. One way to easily fail a Comcheck is to use the wrong code.
Comcheck Energy Code Chart (2024)
For example: Your Comcheck Report required IECC 2024 Comcheck Report but you created your Comcheck Energy report using IECC 2021. The solution would be to use Comcheck Web or New Comcheck to update the Comcheck to the IECC 2024 Comcheck Energy Code.
Another example: You create your Comcheck Using the very stringent IECC 2024 Comcheck Energy Reporting Code. However, the building department automatically failed the project, because the adopted code for their jurisdiction is IECC 2021. The solution would be to use New Comcheck or Comcheck Web to change the project to the correct code.
Overall, it can be easy to enter data incorrectly, choose the wrong components, or use the wrong energy code when creating Comcheck Energy Reports. However, fixing the errors can be easy if you know what to look for. We hope this blog post article on fixing Comcheck report failures can help you.
