Title 24, Part 6, of the California Code of Regulations
Effective January 2010, the California Energy Commission promulgated changes to the “2008 Building Energy Efficiency Standards”, for residential and non-residential buildings.
I recommend a visit to their website at www.energy.ca.gov/title 24 to familiarize the design team with these important changes which will affect non-residential projects. Even though we don’t document energy compliance, the following are some highlights of interest to designers from a summary of changes compiled by Mazi Shirakh, P.E.:
- Revisions and clarification to Sections 130-134, Mandatory requirements for Lighting Systems and Equipment related to Luminaire Power determination, sign lighting controls, and other clarifications.
- Updates for compliance to require side-lighting (§131) and day-lit areas near windows, change definition of day-lit area and requirements for daylighting controls. Update skylight requirements to include smaller buildings (8,000 sf vs. 25,000 sf), buildings with 15 ft ceiling heights (§143(c)).
- Add requirements for occupant sensors in new indoor areas including small offices, multipurpose rooms less than 1,000 sf, classrooms, and conference rooms(§132(d)).
- Compliance credit for high efficacy load shedding ballasts to reduce energy use when signaled (§146).
- Demand response controls to reduce indoor lighting when signaled (§146).
- Revise the outdoor lighting compliance procedure and update outdoor lighting power densities, require outdoor lighting to meet title 24 standards when alterations replace 30% of fixtures (§147).
- Revised Cool Roof requirements for low-slope roofs and add prescriptive Cool Roof requirements for steep-sloped roofs (§143).
- Refinements to additions and alteration requirements for non-residential buildings (§149).
- Revisions and clarifications to Section 118, Mandatory Requirements for Insulation and Roofing Products including introduction of Solar Reflectance Index (SRI) for cool roof compliance.
- Revisions and clarifications to section 119, Mandatory Requirements for Lighting Control devices.
- Changes to Joint Appendix JA4 for wall, roof, and floor assemblies.
