  3. 3. Agenda Who is Adopting EV Infrastructure Building Codes? What to Include in Building Codes? Code Adoption Updates Why Adopt EV Infrastructure Measures Into Building Codes? 3 Conclusion
  4. 4. Why Adopt EV Infrastructure Measures Into Building Codes? Electrical system retrofits Breakage and repair of hardscapes Soft Costs: permitting, inspection, HOA or landlord approvals, etc. 1 – Lack of EV infrastructure is limiting EV adoption, a critical climate change mitigation strategy 4 2 – Building codes can increase EV charging infrastructure by avoid retrofit costs including:

  7. 7. What to Include in Building Codes? No EV Infrastructure EV-Capable EV-Ready (Full Circuit) Levels of EV Charging Infrastructure 7 Additional Topics: Existing Buildings Medium and Heavy Duty Vehicles
  8. 8. EV-Capable Electrical Panel Space and Capacity Accommodate future build-out of EV charging at 10% to 90% of parking spaces, or more, with 208/240 V, 40-amp circuits. Install All Difficult to Access Conduit (raceway) Hard to alter after construction (e.g. enclosed within walls or pavement, etc.); could also require full conduit. Rationale: Provide hard-to-retrofit elements while minimizing up-front cost. What to Include in Building Codes? 78
  9. 9. EV-Ready (Full Circuit) Install Full Circuits for 10% of Spaces During Construction, or More (or one at single family homes). Full circuit includes 208/240V, 40-amp panel capacity, raceway, wiring, receptacle, and overprotection devices - similar to a dryer circuit. Rationale: Full circuits are plug-and-play ready for Electric Vehicle Supply Equipment (EVSE) installation with the least total costs. What to Include in Building Codes? 9
  10. 10. Vehicle-Grid Integration Consider 50-amp electrical service where capacity is available to increase potential for VGI services. Authorize load management systems to share electrical panel capacity among multiple parking spaces. Rationale: • Best utilize electrical system capacity; • Potentially reduce demand charges; • Maximize potential for renewable energy uptake and/or providing grid services. What to Include in Building Codes? 10
  11. 11. Existing Buildings Additions, Major Building Alterations, Surface Parking, and Electrical System Upgrades Rationale: • Buildings typically last 50-years and will need to be retrofit to meet EV adoption goals • Retrofitting during significant alterations, additions is cost-effective. • Examples include the City and County of San Francisco and Marin County. What to Include in Building Codes? 11
  12. 12. Require that some EV-capable and EV- ready spaces are designed to accommodate future build-out of accessible EV charging spaces. Rationale: Good design practices can avoid unnecessary barriers that would be hard to correct later (slope, obstructed pathways, etc). What to Include in Building Codes? 10 12 Accessibility
  13. 13. • Transportation Refrigeration Units • Forklifts • Transit and School Buses Rationale: Charging infrastructure building codes enable electrification. Advanced Building Code Options 10 13 Medium and Heavy- Duty Vehicles
  14. 14. Studies Recommend Code Adoption 14 Stakeholders Have Recommended CALGreen Code Updates: Support for Building Code Adoption
  15. 15. Recent Building Code Updates 15 California Green Building Code (CALGreen) MF update effective January 1, 2020: • State-wide minimum: 10% of spaces EV- capable; • CALGreen voluntary code: up to 20% EV- capable New CALGreen codes for schools CALGreen non-residential code update planned for adoption June 2020 • Should increase from current level of ~6% spaces EV-capable and add alterations/additions
  16. 16. National IECC Building Codes Update 16 Non-residential code proposal • 1 to 2 EV ready spaces and • Roughly 20% EV capable for buildings with 11 or more spaces • Includes multi-family buildings over three stories • Passed through IECC committee with many supporters Residential Proposal • Public comments will be needed to re-consider residential proposal
  17. 17. Example Resources Available to Support Code Adoption: • Outreach presentations • Model building codes and example building codes • Cost-Effectiveness reports • Permitting & Inspection streamlining report 1017 Barriers & Solutions for Building Codes Adoption Potential Barriers to Code Adoption: • Lack of familiarity with EV infrastructure codes • Lack of model codes, cost-effectiveness data and technical resources • Limited stakeholder awareness
  18. 18. Conclusion 18 1 - EV infrastructure building codes: • Highly cost effective; and • Support expansion of EV fleet. 2 - Stakeholders can: • Support national code adoption; • Support state and local code adoption and implementation; and • Encourage consideration of advanced building codes options.

  23. 23. EV Building Code Example: City of Oakland Scenario Full Circuit Inaccessible Raceway Installed Electric Panel Capacity 1 parking space 1 parking space - Able to supply 1 parking space 2-10 parking spaces 2 parking spaces - Able to supply 2 parking spaces 11-15 parking spaces 2 parking spaces 1 parking space Able to supply 3 parking spaces 16-20+ parking spaces 2 parking spaces 2 parking spaces Able to supply 4 parking spaces 21+ parking spaces 10% of parking spaces (rounded up) Multi-Family Buildings: Remaining 90% of spaces Non-Res Buildings: Additional 10%* Able to supply 20% of spaces** *Inaccessible raceway includes raceway installed through walls, under concrete slabs or under asphalt, etc. **Full circuits are counted towards panel capacity requirement
  24. 24. Green Building Codes • California has adopted Green Building Codes (“CALGreen” or Title 24, Part 11) for water efficiency, Electric Vehicle (EV) infrastructure, etc.  Separate from state energy codes (Title 24, Part 6)  Local jurisdictions must adopt mandatory updates and implement by January 1, 2020 • Local cities may adopt their own local Green Building Code amendment - 28 California cities and counties have moved ahead of CALGreen on EV infrastructure codes
  25. 25. Curb-side Charging Examples of Additional Building Code Development Opportunities 1010 Developing codes with details such as set- backs, parking striping, etc. Rationale: Some buildings have limited or no off-street parking.
