The analysis found cost-effective packages across the state for both single family and low-rise multifamily buildings. For the building types and climate zones where cost-effective packages were identified, the results of this analysis can be used by local jurisdictions to support the adoption of reach codes. Cost-effectiveness was evaluated according to two metrics: On -Bill customer lifecycle benefit -to -cost and TDV lifecycle benefit -to -cost. While all the above code targets presented are based on packages that are cost-effective under at least one of these metrics, they are not all cost-effective under both metrics. Generally, the test for being cost-effective under the TDV methodology is less challenging than under the On -Bill methodology. Therefore, all packages presented are cost-effective based on TDV, and may or may not be cost-effective based on the On -Bill method. It is up to each jurisdiction to determine what metric is most appropriate for their application. A summary of results by climate zone are presented in Appendix G — Results by Climate Zone. Above code targets are presented as Target EDR Margin, which have been defined for each scenario where a cost-effective package was identified. Target EDR Margins represent the maximum "reach" values that meet the requirements. Jurisdictions may adopt less stringent requirements. For the Efficiency Package the Target EDR Margin was defined based on the lower EDR Margin of the Efficiency — Non -Preempted Package and the Efficiency — Equipment, Preempted Package. For example, if the cost-effective Non -Preempted package has an EDR Margin of 3 and the Preempted package an EDR Margin of 4, the Target EDR Margin is set at 3. The average incremental cost for the single family Efficiency packages is $1,750. The Efficiency & PV Package average incremental cost is $9,180 and for the Efficiency & PV/Battery Package it is approximately $5,600 for the 41 © 2019-08-01 346
