Compliance: Passes using UA trade-off
5.1% Better Than Code Maximum UA:293 Your UA:278
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.
Compliance:
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.
