The Bay Area Solar Photovoltaic (PV) Ordinance Toolkit, a project of the Bay Area Regional Collaborative1, provides guidance for Bay Area cities and counties that seek to require solar PV systems on new single-family and low-rise multifamily residential units. this ordinance is aligned with State and Federal financial incentives and utility tariffs for exchanging power with the grid.
Bay Area Ordinance Template (editable)
Added “Whereas” findings
Added clarity and text typically used in local government ordinances
Requirements
Offset 80% of a new home’s electricity use
Single family and low-rise multi-family
Various methods to determine capacity
Climate zone
Home size
Exceptions
Ordinance proposal includes:
Sizing requirements tailored to city or county’s climate zones
System shading specifications
Exemptions and alternative compliance option
Solar PV is the default option
Alternative compliance methods
Other forms of renewable electric generation
Solar plus storage
Exceptions if solar is not practical
15% improvement in energy efficiency
Commitment to a community solar program
Requirements can be reduced or waived at the discretion of the building official
Basic energy efficiency requirement
TP 13: Cost-effectiveness is a State requirement for any local reach codes because local amendments to state code must be supported by an analysis that demonstrates cost-effectiveness. A key benefit of the Bay Area Solar PV Ordinance is that its associated cost-effectiveness study, produced by Pacific Gas and Electric (PG&E) using ratepayer funds, has already been recognized by the CEC.
TP 14: The basic model ordinance requires 80 percent of a home’s electricity use to be met with solar power.
TP 15: The solar ordinance requires that buildings first meet Title 24 Energy Code compliance without the use of the PV compliance credit (PVCC), and that solar panels are sized to fulfill the minimum capacity needed to offset approximately 80% of a new building’s electric consumption.
TP 14: Title 24 Energy Code Compliance:
Requires builders to comply with the 2016 Title 24 building energy codes without using a solar credit, which would otherwise allow builders to tradeoff a portion of the required efficiency for solar. By not allowing this tradeoff the ordinance ensures that homes will be as efficient as required by Title 24 Part 6 and have solar power.

33% renewable by 2020 & 50% by 2030
Statewide GHG Reduction Goal:
40% below 1990 levels by 2030 & 80% below by 2050

5. Adoption pre-2019 Code Update
All local amendments to building code updated at each 3 year code cycle
Process and Timeline: ~ 6 months but likely less
Factors to consider:
Ordinance and cost-effectiveness analysis prepared in conjunction with and aligned with CEC
CEC has modified its compliance forms to include an output specifically to demonstrate compliance with the proposed requirements.
While six months may be typical for other amendments, approval of the solar ordinance will be much quicker. The ordinance and cost-effectiveness analysis have already been vetted by the CEC in order to speed the approval process. The longest part of the process is the 60 days noticing requirement for the CEC agenda. Other than that, approval should be very straightforward.
Adoption of the proposed ordinance will capture opportunities for installations in new construction prior to 2020 that would otherwise be lost and help prepare staff and the development community for the transition to ZNE in 2020.
Demonstrate Local leadership
Achieve CAP Goals
Advance and accelerate state GHG reduction goals
Address specific local conditions
Anticipated growth or other trends
Achieve savings ahead of new building code cycle
Effective January 1, 2020
2018 adoption ensures at least one year of implementation.

6. Advantages of Adoption Now
Pave the way for 2019 Standards implementation
Mitigate lost opportunities for capturing solar in cities with higher growth
Achieve savings ahead of new building code cycle
Solar increases home value
Adds $4 to home value per watt of solar – Laurence Berkeley National Lab*
GHG Reductions: 43 – 47%
Min. $360 annual savings (up to $720)
2019 standards will be more stringent
What’s coming down the pipe?
Adding new prescriptive requirements for installing solar photovoltaic systems in newly constructed residential buildings, and specifying use of an Energy Design Rating in the performance approach to compliance to support solar photovoltaic requirements. In addition, Joint Appendix 11 and 12 have been added to support solar photovoltaic and battery storage systems installed to comply with Part 6.
Adoption of the proposed ordinance will capture opportunities for installations in new construction prior to 2020 that would otherwise be lost and help prepare staff and the development community for the transition to ZNE in 2020.

Outreach Materials: Presentation template, FAQ
As part of the program, these regional agencies have designed a toolkit to provide local governments with tools and materials to facilitate amending their existing building codes to accelerate the adoption of rooftop solar electricity generation. Take advantage of lessons learned from Bay Area local government experiences
Efficiently use a step-by-step guide to adopt solar reach codes and get them approved by the State
Use editable time-saving templates
The program offers Bay Area jurisdictions additional support to consider ordinance enhancements, and will provide opportunities to convene with peers from other jurisdictions, and technical expertise to explore these enhancements.
The Toolkit provides a staff report template to streamline the preparation of the ordinance for presentation to the local governing body. The template includes staff recommendations, background information, a summary of the ordinance requirements, impacts, and a CEQA compliance statement. The Word template can be downloaded for easy editing.
Solar Permitting: A key benefit of the Bay Area Solar PV Ordinance is that its associated cost-effectiveness study, produced by Pacific Gas and Electric (PG&E) using ratepayer funds, has already been recognized by the CEC. Therefore, if a local jurisdiction adopts the Bay Area Solar PV Ordinance without modifications to the scope, the cost-effectiveness study in this Toolkit may be used to satisfy State requirements, and the approval process will be streamlined.

10. Ways we can partner
Support throughout adoption process; informational presentations
Facilitate information exchange
Provide resources for outreach
Thought-partner on work session topics
Per your request:  a brief description of the rationale for discussion of the calculation methodology for minimum PV system size in the model ordinance.
Implementing the Model Solar ordinance requires access to information that is not currently contained in the compliance documentation.  The compliance documentation author may view the data on-screen, but there is no existing form that contains the information required to ensure the permit application meets the ordinance PV minimum system sizing requirement to offset 35-55% of TDV energy (depending on climate zone) or approximately 80% of site electricity use.  The objective of the discussion will be to review [a worksheet or form---HOPEFULLY] that shows where the numbers are located and how to calculate the relevant values.
