EV-Readiness & Building Codes by Eric Huang

  1. 1. Forth Webinar | EV-Readiness and Building Codes Why it matters and what to adopt in the area of residential charging. Eric Huang Program Manager EricH@forthmobility.org 05.14.2019 EV-Readiness & Building Codes 1
  2. 2. ● Building Codes Introduction ● Why EV-Readiness? Why Building Codes? ● EV-Readiness Building Codes Recommendations 2 Today’s Topics:
  3. 3. Forth Webinar | EV-Readiness and Building Codes What are Building Codes? “Collection of laws, regulations, ordinances adopted by a government legislative authority with the physical structure and health conditions of buildings and building sites” ● Who creates model codes? ○ ICC - Int’l Code Council ○ NFPA - National Fire Protection Association ○ ASHARE - American Society of Heating and Air-Conditioning Engineers ● What codes are there? ○ IBC - Int’l Building Code ○ IRC - Int’l Residential Code ○ IECC - Int’l Energy Conservation Code ○ NEC - National Electrical Code 3

  9. 9. • Building codes are generally divided by sections such as Building, Electrical, Mechanical, and Plumbing. • Model Codes are developed by specific agencies and adopted by state, municipality, and sometimes nation. • The ability of each level to create and enforce code varies widely depending on the state and locality.

  12. 12. Forth Webinar | EV-Readiness and Building Codes The Environmental Impact of EVs ● Transportation Emission accounts for 23% of global energy-related greenhouse gas emissions ○ EV Charging Infrastructure is vital to EV adoption for the general consumers ○ States have big goals for EV (CA, OR, IL …) ○ Electrification of Transportation is an integral part of nations and cities climate action plans ● IEA 2017 EV Outlook: ○ “The availability of chargers emerged as one of the key factors for contributing to the market penetration of EVs. Ensuring the availability of chargers is also essential for enabling the diversification of the transport fuel mix and catalyzing its transition towards clean energy.” 12
  13. 13. Forth Webinar | EV-Readiness and Building Codes The Need for EV Charging Infrastructure ● The Rising Adoption of EV ● The Conducive EV Infrastructure: ○ Public Charging Stations ○ Workplace Charging ○ Home Charging ● Public DCFC isn’t priced competitively enough and not prevalent enough ● Workplace charging is picking up but not everyone drives to work (limited availability as well) ● Home charging can potentially serve the gap with great economics 13
  14. 14. Forth Webinar | EV-Readiness and Building Codes Why we care about building codes for EV? ● Access to charging is critical ○ MUD tenants have substantial barriers installing EVSE ○ Full circle: Residential, workplace, and public charging ● Building codes nowadays have energy efficiency requirements, which will free up electrical capacity for the building to accommodate EV charging ● New buildings: ○ Last for decades ○ EV readiness is a technology-neutral ○ EV charging is a marketable amenity ○ Financially optimal comparing to retrofitting 14

  17. 17. Forth Webinar | EV-Readiness and Building Codes Definitions ● EVSE: Electric Vehicle Supply Equipment: ○ The conductors, including the ungrounded, grounded, and equipment grounding conductors, and the Electric Vehicle connectors, attachment plugs, and all other fittings, devices, power outlets, or apparatus installed specifically for the purpose of transferring energy between the premises wiring and the Electric Vehicle. ● EV-Capable Space: ○ Electrical panel capacity and space to support a minimum 40-ampere, 208/240-volt branch circuit for each EV parking space, and the installation of raceways, both underground and surface mounted, to support the EVSE. ● EV-Ready Space: ○ A designated parking space which is provided with one 40-ampere, 208/240- volt dedicated branch circuit for EVSE servicing Electric Vehicles. The circuit shall terminate in a suitable termination point such as a receptacle, junction box, or an EVSE, and be located in close proximity to the proposed location of the EV parking spaces.

  18. 18. Forth Webinar | EV-Readiness and Building Codes What to propose/adopt? Requirement models: ● Where? ○ Residential ○ Commercial ○ New construction vs. existing construction ● What? ○ Requirement for a certain % or # of the off-street parking spaces provided with EV charging infrastructure; ○ Requirement for a minimum performance level for EV infrastructure relying on load-share; 18
  19. 19. Forth Webinar | EV-Readiness and Building Codes Key Factors in Building Code Language ● New Construction / Major Renovation vs. Existing Buildings ● Single Family and Small Multi-Unit vs. Multi-Unit-Dwelling/Commercial ● Electrical Capacity and Panel Requirements ○ Load management capability ● Specific EV Parking Space Requirements ○ Level of Readiness: ■ EV-Ready ■ EV-Capable ○ % of parking space ○ Accessibility requirement ○ Identification and signage ○ Distance to the electrical panel ■ Deeded vs. non-deeded 19

  30. 30. Forth Webinar | EV-Readiness and Building Codes Electric Vehicle Ready Parking (Excerpt) (3) Nothing in this rule requires the installation of electric vehicle charging stations in a parking facility. (4) The program is mandatory within the jurisdictional boundaries of: The cities of Portland, Eugene, Salem and Gresham; and municipality that has adopted the program through the local amendment process. (6) The program applies to the new construction of parking facilities with 50 or more open parking spaces. Five percent (5%) of the open parking spaces must be available for future installation of electric vehicle charging stations. Fractional numbers derived from this calculation must be rounded up to the nearest whole number. (8) Unless otherwise stated in this rule, electrical installations must be according to the Oregon Electrical Specialty Code. (a) A parking facility must have a conduit system installed from the building electrical service to the open parking spaces. (A) The conduit system must be, at a minimum, capable of supporting the installation of electrical wiring for the future installation of electric vehicle charging stations rated “Level 2” (40 amp/3.3 – 6.6 kW) or larger, as specified by the owner. (B)Any conduit installed for future electric vehicle charging stations must be labeled “For Future EV Charging Stations.” Both ends of the conduit must be labeled for the environment it is located in. 30 Oregon
