EKO_Q16_FoundationWalls Version 7.1.1

PHOTO REQUIRED or additional documentation required of foundation wall insulation per ANSI/RESNET/ICC 301-2019 APPENDIX B and MINHERS Chapter 9. Raters/RFIs are responsible for documenting reasons for missing photos. For all foundation walls, confirm that the foundation wall types, thicknesses & studs; insulation R-values, grades & dimensions; lengths & heights; heights above & depths below grade; and locations which are entered into the software correspond with plans and/or field data collected by the Rater/RFI for the actual condition of the rated home.

• Be sure that where multiple foundation wall types exist, they are handled separately, including where their “location” with respect to conditioned areas of the home may vary between wall types and within the same wall type.

SCORING:

• Satisfactory: No errors in modeling
• 1: one to two minor errors in modeling (listed below) (this is per modeled wall)
• 2: NO PHOTO OR three to four minor errors (listed below) in modeling OR one to two major errors in modeling (this is per modeled wall)
• 3: five or more minor errors (listed below) OR three or more major errors in modeling (listed below) (this is per modeled wall)

GUIDANCE:

Minor AGW Modeling Errors:

• Insulation thickness of each modeled Foundation Wall (not including framing) off by 0.5 to 1.0 inch
• Incorrect Foundation Wall Construction Type modeled
• If the wall is framed out and finished on the interior, Incorrect Foundation Wall Studs Type modeled
• Insulation R-Value of each modeled Foundation Wall off by 5% to 10%
• If Continuous Insulation, Top of Wall to Top of Continuous Insulation of each modeled Foundation Wall off by 0.5 to 1.0 foot
• If Continuous Insulation, Top of Wall to Bottom of Continuous Insulation of each modeled Foundation Wall off by 0.5 to 1.0 foot
• If Stud/Cavity Layer, Incorrect Insulation Material of each Foundation Wall modeled
• If Stud/Cavity Layer, Incorrect Stud Type of each Foundation Wall modeled
• If Stud/Cavity Layer, Incorrect Sheetrock Thickness of each Foundation Wall modeled
• Height Above Grade of each modeled Foundation Wall off by 0.5 to 1.0 foot (distance from grade level to the top of the foundation wall)
• Depth Below Grade of each modeled Foundation Wall off by 0.5 to 1.0 foot (distance from grade level to the top of the slab floor)
• Total Horizontal Exterior Perimeter Length of each modeled Foundation Wall off by 5% to 10%
• Incorrect Enclosure of each Foundation Wall modeled
• Incorrect Location of each Foundation Wall modeled

• Insulation R-Value of each modeled Foundation Wall off by greater than 10%
• Incorrect Insulation Grade of each modeled Foundation Wall (based on ANSI/RESNET/ICC 301-2019 Appendix A depth/void variance for insulation type and grade)
• If Continuous Insulation, Top of Wall to Top of Continuous Insulation of each modeled Foundation Wall off by greater than 1.0 foot
• If Continuous Insulation, Top of Wall to Bottom of Continuous Insulation of each modeled Foundation Wall off by greater than 1.0 foot
• If Stud/Cavity Layer, Incorrect stud depth, spacing, or framing fraction modeled
• Height Above Grade of each modeled Foundation Wall off by greater than 1.0 foot (distance from grade level to the top of the foundation wall)
• Depth Below Grade of each modeled Foundation Wall off by greater than 1.0 foot (distance from grade level to the top of the slab floor)
• Total Horizontal Exterior Perimeter Length of each modeled Foundation Wall off by greater than 10%
