About this app
For use with the International Code Council’s 2012 International Energy Conservation Code (IECC) or International Residential Code (IRC), this app provides wood solutions for the Total UA alternative method. Opaque wall U-factors are calculated based on improved fenestration performance. Either an unknown opaque wall or fenestration U-factor can be determined. The app also gives insulation requirements needed in various wall assemblies to achieve the opaque wall U-factor. Wall assemblies include 2x4 and 2x6 wood framing at 16” and 24” o.c. spacing as well as several cladding and sheathing options. The Energy UA Calculator is consistent with AWC’s Design for Code Acceptance (DCA) 7 - Meeting Residential Energy Requirements with Wood-Frame Construction - 2012 IECC Version which provides ways to economically meet the residential requirement of the 2012 IECC.
