<br />2019 Energy Efficiency Ordinance Cost-effectiveness Study
<br />the Utility Gas Main Extensions rules 50% refund and appliance allowance deduction are not applied and
<br />therefore the cost savings are approximately 2.5 times higher.
<br />With the Efficiency & PV Package and the On -Bill analysis, due to the added cost of the efficiency and PV there is
<br />a net cost increase for the all -electric case in all climate zones for except 7, 8, 9, and 15. With the TDV analysis,
<br />there is still an incremental cost savings in all climates. Like the single family results, utility costs are typically
<br />higher for the code compliant all -electric option but lower than the code compliant mixed fuel option with the
<br />Efficiency & PV Package.
<br />The all -electric code compliant option is cost-effective based on the On -Bill approach for multifamily in Climate
<br />Zones 6 through 9, 10 and 14 (SCE/SoCalGas territory only), and 15. Based on the TDV methodology, the code
<br />compliant option for multifamily is cost-effective for all climate zones. If the same costs used for the On -Bill
<br />approach are also used for the TDV approach (incorporating the Utility Gas Main Extensions rules 50% refund
<br />and appliance allowance deduction), the all -electric code compliant option is cost-effective in Climate Zones 8
<br />and 9. Like the single family cases, the Efficiency & PV all -electric option is cost-effective in all climate zones
<br />based on both the On -Bill and TDV methodologies.
<br />The last set of results in Table 16 show the neutral cost case where the cost savings for the all -electric code
<br />compliant home is invested in a larger PV system, resulting in a lifetime incremental cost of zero based on the
<br />On -Bill approach. This package results in utility cost savings in all cases except Climate Zone 1. For this case the
<br />Reach Code Team evaluated how much additional PV would be required to result in a cost-effective package.
<br />These results are presented in Table 17 and show that an additional 0.3kW per apartment results in a B/C ratio
<br />of 1.1. Neutral cost cases are cost-effective based on the TDV methodology in all climate zones except 16.
