IECC 2024 Section R402.2.7: Steel-Frame Assembly U-Value Calculation

Modified on Tue, 11 Mar at 5:09 PM

In IECC 2024 Prescriptive path, Section R402.2.7, the U-Factor calculation for steel-frame walls was updated to comply with AISI S250. This is not supported in the Ekotrope software and will cause the Total TC QA check to fail. To use steel-frame walls, you must use a classic entry and manually enter an R-Value. 


You will see this warning


In order to get around this edit your wall and click "Switch to Classic Entry"


You must manually calculate and enter the R-Value according to AISI S250
