CALGreen Codes for Residential Buildings Cities can adopt the measures in CALGreen or adapt them to reflect local priorities. For example, the City of Santa Monica has adopted the measures in CALGreen and has redefined low-rise residential to mean buildings of six stories or less (Santa Monica Municipal Code 2010). The CALGreen code language is excerpted below (California Building Standards Commission 2012 Supplement): A4.106.6.1 One-and two-family dwellings. Install a listed raceway to accommodate a dedicated branch circuit. The raceway shall not be less than trade size 1. The raceway shall be securely fastened at the main service or subpanel and shall terminate in close proximity to the proposed location of the charging system into a listed cabinet, box or enclosure. Raceways are required to be continuous at enclosed or concealed areas and spaces. A raceway may terminate in an attic or other approved location when it can be demonstrated that the area is accessible and no removal of materials is necessary to complete the final installation. 12

CALGreen Codes for Residential Buildings A4.106.6.2. Multifamily dwellings. At least 3 percent of the total parking spaces, but not less than one, shall be capable of supporting future electric vehicle supply equipment (EVSE). A4.106.6.2.1 Single charging space required. When only a single charging space is required, install a listed raceway capable of accommodating a dedicated branch circuit. The raceway shall not be less than trade size 1. The raceway shall be securely fastened at the main service or subpanel and shall terminate in close proximity to the proposed location of the charging system into a listed cabinet, box or enclosure. A4.106.6.2.2 Multiple charging spaces required. When multiple charging spaces are required, plans shall include the location(s) and type of the EVSE, raceway method(s), wiring schematics and electrical calculations to verify that the electrical system has sufficient capacity to simultaneously charge all the electrical vehicles at all designated EV charging spaces at their full rated amperage. Plan design shall be based upon Level 2 EVSE at its maximum operating ampacity. Only underground raceways and related underground equipment are required to be installed at the time of construction. 13

CALGreen Codes for Non-Residential Buildings A5.106.5.3 Electric vehicle charging. Provide facilities meeting Section 406.7 (Electric Vehicle) of the California Building Code and as follows: A5.106.5.3.1 Electric vehicle supply wiring. For each space required in Table A5.106.5.3.1, provide panel capacity and dedicated conduit for one 208/240V 40 amp circuit terminating within 5 feet of the midline of each parking space.

Recommendations The following recommendations are intended to facilitate PEV charging through building codes. These recommendations should be adapted to reflect local land use opportunities for PEV charging and anticipated PEV demand, which may vary greatly among cities. Consider expanding the range of new buildings to which PEV readiness codes apply beyond Allow Level 1 or Level 2 charging capability to satisfy PEV readiness requirements in building Require the laying of conduit capable of carrying future wires or cables from the electrical room to Source: UCLA Luskin Center, SoCal PEV Readiness Plan 15

Recommendations Consider present PEV charging demand in determining whether to require installation of ready- Require a certain minimum percentage of parking spaces in new construction be wired to be PEV- Require a certain minimum percentage of parking spaces in new construction be wired to be PEV- Consider updating electrical codes to allow automated energy management system. 16

Can SCE s Power Supply Accommodate PEV Charging? No capacity issue to meet the charging needs of EV adopters Most charging currently occurs overnight/off-peak with minimum impact on the utility system 14 million people, 5 million customers. 50,000 square mile territory includes 180 cities. There is some potential for local distribution issues if EV customers do not notify their utility before they charge their EV for the first time; the utility may need to upgrade the grid locally 21

APPENDICES 35

The TOU-EV-1 Rate The customer s electric vehicle usage is tracked by a 2 nd, dedicated meter while the house remains separately metered on the current rate This option requires the customer to install a 2nd panel or meter socket box. SCE approves the location of the 2nd panel or the new upgraded panel, and installs the 2nd meter after receiving inspection approval This module provides an overview of the process for customers who choose SCE s Electric Vehicle Plan also known as the T-O-U or Time-of Use-EV-1 rate. Customers selecting this EV rate will be required to install a 2 nd panel or meter socket box for a SCE meter to separately track the usage for charging an EV. The electrician is encouraged to work closely with SCE s Service Planner to ensure their plan, including the location of the 2nd meter, complies with SCE s Electrical Service Requirements, often referred to as the ESR. SCE will install the 2 nd meter after receiving inspection approval from the local authority having jurisdiction.
