Our project team would like to achieve SSc4.3 through Option 3, Alternative Refueling Stations. The project consists of a low rise residential complex in Portland, Oregon, with underground parking provided to tenants. We propose that the project earn compliance with the credit requirements by providing electric vehicle refueling stations for 3% of building occupants. In response to the local market and the evolution of electric vehicles from those requiring a 240v outlet to models that can be effectively refueled using a standard 120v outlet, we request that this approach be reviewed as an acceptable compliance path. We believe this compliance path is in alignment with guidance presented in the NC v2.2 Reference Guide. Specifically, language related to SSc4.3 in the NC v 2.2 Reference Guide provides substantial flexibility for the selection of the refueling station type. In the Reference Guide, applicants are encouraged to "compare the environmental and economic costs/benefits of different alternative fuel types," "investigate local codes and standards for refueling stations in the area," and "compare different fuel stations equipment options and fuel availability" in the project area. After a thorough review of the electric vehicles available in the Portland area, our project team has confirmed that the vast majority of the electric vehicles available require a 120v outlet for refueling. A CIR ruling dated 9/10/2007 indicates that quick charge capacity is viewed as desirable, "as it is likely contribute to increase the rate of all-electric usage"; however, the majority electric vehicles sold in the Portland region are not compatible with 240v outlets and consequently would require the vehicle owner to purchase an adapter to utilize refueling stations with higher voltage outlets. Additionally, as our project site has been selected for its close proximity to downtown Portland and connectivity to important community services, residents will more than likely be recharging their vehicles daily, primarily requiring overnight charging with a 120v outlet. Overall, we believe that the combination of these factors demonstrates that installing 120v outlets achieves the credit intent and will effectively contribute to the expansion of electric vehicle use. Please confirm that the installation of 120v outlets meets the intent of the credit.
