Reach Codes
1
Fall 2019
Agenda . . .
•Silicon Valley Clean Energy (SVCE)
•How SVCE supports city goals
•Building Codes and Amendments to code (aka Reach Codes)
•What, Why, To What Degree
•Options
•Where do we go from here
•Question and Answer
Summary Points . . .
3
Who is SVCE?Community-owned and governed non-profit agency –
focused on affordable clean energy and emissions reduction.
Is electricity on the grid getting cleaner? Yes, quickly!
Where do most residential emissions
and gas use come from?
Water heating and space heating.
Is electricity more efficient than natural gas
for heating?
Yes, though it didn’t used to be . . .
Will ‘Reach Codes’ ban natural gas? No. They encourage use of clean electricity in new construction
only, and don’t require it.
Why Reach Codes? Economics, comfort, safety, environmental performance

1.Major goals for CA
1.Electricity –via SVCE
2.Natural Gas
3.Transportation Fuels
Pathway toward Goals
2050
Goal -2050
On Building Codes
o New Codes come out every 3 years –this is one of those years
o Cities have the authority to amend the code to go above state
minimums
o We are discussing these amendments to the code, also known
as reach codes

Built Environment via Code
2018
•Member Agency Working Group (city staff) –included building and EV codes within top priorities for SVCE
•Customer Program Advisory Group (volunteers from each member city) –Recommendation to SVCE Board:
Increase readiness for planned, economic migration from fossil-fuel use to efficient, clean electricity use in
residential homes.
•Industry Expert Stakeholder Charette –Advancing building electrification within code both for efficiency and EV’s.
•SVCE Board Approves SVCE to contract with building code consultants to support member cities with reach codes
2019
•SVCE’s code consultant team engage city staff and external stakeholders, solicit input, develop reach code options,
provide support system (technical, writing, meeting, other) for member cities

Emissions
On average, over 80% of emissions come from
Space & Water heating. There is a reach code
option designed specifically to address this….

Other Benefits of Electric Homes
•All-electric homes typically cost about $5,000 less to construct as they do not require
gas service and they use a single heat pump for both heating and cooling
rather than two separate devices.
•Improved indoor air quality –reduces respiratory issues, including asthma
•Safer –reduced burn risk from induction stoves, overall improvement in personal
wellness and reduced property damage during house fires.
9
Purpose of Reach Code
•Reduce pollution from within the home
•Facilitate increased adoption of electric vehicles
•Encourage developers and homeowners to select lower-cost, healthier,
safer appliance options
•Prepare new homes for future electric appliances via pre -wiring
Not a Ban on natural gas
Where does the Reach apply
o New Construction [not existing homes]
o Any major remodel as your jurisdiction
o Within the shell of the new building
o Outdoor features (pools, fire pits, etc.) not impacted by this
o (optionally) Detached Accessory Dwelling Units (ADU)

Options w/in Reach Code -Homes
All-Electric (1) Electric & Gas (2)
Cost + $0
Meet Title 24 requirements
Cost + $8,500
Meet Title 24 requirements, including:
•Pre-wire for future electric heat pump
•Pre-wire for future electric appliances
•Additional Energy Efficiency
•Solar thermal or Battery Storage
“Mostly Electric” (2A)
Cost + $1,500

•Install Electric water and space heating
(allows natural gas for cooking)
•Pre-wire for future electric range
•Additional Energy Efficiency measures
•Solar thermal or Battery Storage
12
Emissions
1)All-Electric home –reduce emissions by 100%.
2) Electric + Gas –reduce emissions by less than 10% (mainly due to better insulation).
2A) Mostly Electric –reduce emissions by 86% (all Space and Water heating reduced to 0)
Options -Buildings
To encourage the use of healthier, safer electric appliances,
Select any or all of the following for homes using natural gas:
o Pre-wiring –at gas appliance locations, pre-wire for future electric
appliances.
Estimated cost = $1500
o Energy Efficiency –install better insulation and ventilation.
Estimated Cost = $1500
o Energy Resources –install either solar thermal or battery storage.
Estimated Cost = $5500

1.Include extra EV Charger capability w/in the Garage (+ $1000)
•Quantity –include one or more above the single charger required by code
•Readiness –Capable,Ready, or fully Installed
•Speed –will the extra charger(s) be Level 1 (40 mile overnight charge) or Level 2 (150 mile overnight charge)?
2.Include an EV Charger (outlet) outside the Garage (+ $1000)
•Quantity –include one or more outlets
•Readiness –Capable,Ready, or fully Installed
•Speed –will the extra outlet(s) be Level 1 (40 mile overnight charge) or Level 2 (150 mile overnight charge)?
Capable –conduit, capacity within circuit breaker
Ready –as Capable above, plus actual breaker in panel, wire, and outlet (like a dryer outlet) ready for a plug-in charger
Installed –as Ready above except the actual EV charger installed instead of just an outlet (rarely done!)

What’s Next
1)Residents ask questions and provide comments
•Public input opportunity
2)City staff, per council motion, drafts staff report
•Options for Buildings
•Options for Electric Vehicle charging
•Support documentation including cost & energy efficiency
3)City staff presents staff report at Council meeting for Council
consideration
•Public input opportunity
