City of Daly City Locally Adopted Energy Standards Approval

Contact: Joseph M. Loyer, 654-4811
Action Requested of Efficiency Policy Committee: Committee approval to bring this item before the full California Energy Commission for consideration and approval.
Business Meeting Date: December 29, 2010
Background: The California Public Resources Code establishes a process that allows cities or counties to adopt and enforce locally adopted energy standards that are more stringent than the statewide standards. This process, described in Section 25402.1(h)(2) and the California Building Energy Efficiency Standards, Title 24, Part 1, Section 10-106 (Standards), allow cities or counties to adopt new versions of the Standards before their statewide effective date (early adoption), require additional energy efficiency measures, or set more stringent energy budgets. The governing body of the city or county is required to make a determination that the standards are cost effective and adopt the findings at a public meeting. The city or county is required to file this determination of cost effectiveness with the California Energy Commission. The Energy Commission must find that the standards will require the diminution of energy consumption levels permitted by the current Standards. The proposed local ordinance cannot be enforced until it is approved by the Energy Commission.
On December 14, 2009, the City Council of Daly City approved the Green Building Program (Ord. No. 1346) requiring newly constructed residential buildings under their jurisdiction to exceed the 2008 Building Energy efficiency Standards (Title 24, Part 6) of the California Building Code by 15 percent. The ordinance requires covered projects to achieve 50 points under the GreenPoint Rated rating system developed by Build It Green. GreenPoint Rated has a mandatory requirement of 15 percent energy saving compared to the 2008 Standards. Alternatively, the ordinance allows 32 points to be achieved under the Leadership in Energy Efficiency Design (LEED) for Homes rating system developed by the U.S. Green Building Council. This is likely to lead to energy savings greater than required by the 2008 Standards, but the amount of savings is not known.
Applicants are allowed to seek relief from the requirements of the ordinance through an appeal process. However, the City of Daily City has assured the Energy Commission that the requirements of Title 24, Part 6 will be fully enforced.
A detailed summary of the proposed local energy standard is provided in Attachment A. The complete application including the full proposed ordinance and cost effectiveness analysis will be made available on the Commission web site upon Commission approval of the proposed ordinance.
The City of Daly City has been informed that the approved ordinance will be enforceable while the 2008 Building Energy Efficiency Standard (Title 24, Part 6) of the California Building Code is enforced and upon implementation of a new adopted State Standard, the City of Daly City will be required to resubmit an application for a local energy standard under Public Resources Code Section 25402.1(h)(2) and Section 10-106 of Title 24, Part 1.
Justification for Action Requested: Energy Commission staff has found that the application meets all requirements under Public Resources Code Section 25402.1(h)(2) and Section 10-106 of Title 24, Part 1. Energy Commission staff believes that the City of Daly City is to be commended for seeking to achieve the energy savings that result from their local energy ordinance..
Pros: If complied with as anticipated, the local ordinance will achieve additional energy savings beyond Title 24, Part 6. The City of Daly City is endeavoring to be a national leader by adopting this ordinance and keeping it ahead of the requirements of the statewide standards. Its approval indicates the Energy Commission’s support for this goal and for active enforcement of both the local ordinance and the statewide standards.
Cons: A possible con is that builders will react negatively to the local variation of requirements or additional costs that may result from complying with the local ordinance.
What Happens Next: Staff will bring the ordinance to the December 15, 2010 Business Meeting for approval.

  2. Other

    1. The ordinance provides an appeal process to seek relief from the requirements of the ordinance. However, the City of Daly City will enforce the requirements of Title 24, Part 6 for all covered projects.



1 Title 24, Part 6: Refers to the 2008 Building Energy Efficiency Standards (Title 24, Part 6) of the California Building Code.
