EKO_Q14_Slab Version 7.1.1

PHOTO REQUIRED or additional documentation required of slab perimeter insulation per ANSI/RESNET/ICC 301-2019 APPENDIX B and MINHERS Chapter 9. Raters/RFIs are responsible for documenting reasons for missing photos. For each slab type, confirm that the area, perimeters, depth below grade, floor covering (and R-value), exposures, insulation type, grade and R-values 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. Typically, Raters/RFIs are not present when slab insulation is installed before the slab is poured, and are therefore not able to collect photodocumentation. One option is that field verifiers can photodocument a slab insulation inspection of homes on the same builder’s adjacent lots while in the area performing pre-drywall and/or final inspections. As an alternative, the builder can provide slab insulation photos and documentation for the home. The QAD should verify that the documentation provided is sufficient to confirm the quality and accuracy of the installation.

• Slab Floors are handled differently in the modeling software based on their exposure and depth below-grade. Slab floors should be separately modeled as covered or exposed. The software provide guidance on how each exposure and location condition is to be handled.

SCORING:

"Satisfactory" when correct or "Unsatisfactory" when incorrect.

GUIDANCE:

• R-Value and Grading - Rater/RFI is within ANSI/RESNET/ICC 301-2019 Appendix A depth/void variance for insulation type and grade identified
• Slab Surface Area - QAD value within 10% of Rater/RFI value
• Depth Values - QAD value within 1' of Rater/RFI value
• Perimeter Values - QAD value within 5% of Rater/RFI value
• Floor covering correct for each slab section
• Covering R-Value - Value in software corresponds with supporting docs or onsite verification
• Grade - Value in software corresponds with supporting docs or onsite verification
• Exposure - Value in software corresponds with supporting docs or onsite verification
