Compliance: Passes using UA trade-off
Compliance: 1.1% Better Than Code Max UA: 92 Your UA: 91
The % Better or Worse Than Code Index reflects how close to compliance the house is based on code trade-off rules. It DOES
NOT provide an estimate of energy use or cost relative to a minimum-code home.
Slab-on-grade tradeoffs are no longer considered in the UA or performance compliance path in REScheck. Each slab-on-grade
assembly in the specified climate zone must meet the minimum energy code insulation R-value and depth requirements.
Compliance Statement
The proposed building design described here is consistent with the building plans, specifications, and other calculations
submitted with the permit application. The proposed building has been designed to meet the 2021 IECC requirements in
REScheck-Web and to comply with the mandatory requirements listed in the REScheck Inspection Checklist.
