EKO_Q15_FramedFloors Version 7.1.1

This refers to Framed Floors that separate conditioned from unconditioned space (i.e., framed floors over unconditioned crawl spaces or basements, over unconditioned garages, over porches, or cantilevers over ambient outdoor conditions); not framed floors between stories inside the thermal envelope. For all framed floors, confirm that the types, insulation types, depth, grade and R-values, framing specifics, surface areas, locations, exposures and floor covering 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. Framed floors should be separately modeled as covered or exposed.

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

SCORING:

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

GUIDANCE:

Minor Framed Floor Modeling Errors:

• Incorrect Insulation Location modeled
• Insulation R-Value of each modeled Framed Floor off by 5% to 10%
• Insulation depth of each modeled Framed Floor off by 0.5 to <1.0 inch
• Incorrect Framed Floor Construction modeled
• Framed Floor Surface Area of each modeled Framed Floor off by 4% to 7%
• Incorrect Framed Floor Location & Exposure modeled
• Incorrect Floor Covering R-Value for each Framed Floor section

Major Framed Floor Modeling Errors:

• Insulation R-Value of each modeled Framed Floor off by greater than 10%
• Insulation depth of each modeled Framed Floor off by greater than 1.0 inch
• Incorrect Insulation Grade value modeled (based on ANSI/RESNET/ICC 301-2019 Appendix A depth/void variance for insulation type and grade)
• Incorrect joist depth, spacing, or framing fraction modeled
• Framed Floor Surface Area of each modeled Framed Floor off by greater than 7%
