Section R406.5 ERI-based compliance is amended to read as follows: <br />R406.5 ERI-based compliance. Compliance based on an ERI analysis <br />requires that the rated design and each confirmed as -built dwelling unit be <br />shown to have an ERI less than or equal to the appropriate value <br />indicated in Table R406.5 as compared to the ERI reference design as <br />fellows:. The values in Table R406.5 shall be achieved prior to accounting <br />for the installation of any on -site power production (OPP). <br />1. Where on site renewables are not installed, the values under <br />ENERGY RATING INDEX NOT INCLUDING OPP apply. <br />2. Where on site renewables arc inota td, the values undor ENERGY <br />RATING INDEX WITH OPP apply. <br />Exception: For buildings with 20 or more dwelling units, where <br />approved by the code official, compliance shall be permitted using <br />the Average Dwelling Unit Energy Rating Index, as calculated in <br />accordance with ANSI/RESNET/ICC 301. <br />1.

Where the ERI analysis excludes on site power production <br />{OPP), the values un, ENERGY RATING INDEX NOT <br />INCLUDING OPP to permittcd to bc applied. <br />This table adjusts the 2024 base code's ERI levels <br />for our Climate Zone 5. It makes all -electric homes <br />easier to meet than mixed fuel homes, and it makes <br />regular sized homes easier to meet than large or <br />extra -large homes. <br />[Simplification from base and LECC] [Strengthening from <br />base and LECC] <br />22.Table R406.5 Maximum Energy Rating Index is replaced as follows: <br />TABLE R406.5 MAXIMUM ENERGY RATING INDEX <br />BUILDING SIZE MIXED FUEL ALL -ELECTRIC <br />Dwelling units with an average of <3,500 <br />square feet (325 m2) or less of conditioned 50 54 <br />floor area <br />
