Title 24 2013 Building Energy Efficiency Standards

California's Building Energy Efficiency Standards are updated on an approximately three-year cycle. The 2013 Standards will continue to improve upon the current 2008 Standards for new construction of, and additions and alterations to, residential and nonresidential buildings. The 2013 Standards will go into effect on January 1, 2014.
1. Clarification and simplification of existing language; removing exceptions no longer relevant. (Section 130.0‐130.5, 140.6‐140.8)
2. Lighting control devices moving from Title 24 to Title 20; Lighting control systems shall now be acceptance tested for Title 24. (Section 110.9(b) & Section 130.4(a))
3. Nonresidential indoor lighting, advanced multi‐level lighting controls (controllable ballasts) increased in granularity (in addition to ON/OFF, increasing from one intermediate level to three intermediate levels for or continuous dimming), favoring dimmable ballasts for linear fluorescent lighting systems. These controls will allow precise and non‐interruptive adjustment of lighting to match the available daylighting, and provide dimming and demand response function throughout the building. (Section 130.1(b) & Section 130.1(a) 2C)
4. Enhancing, modifying, and daylighting controls mandatory requirements (removed off ramps); daylighting language significantly simplified. (Section 130.1(d) Inserted prescriptive daylighting control requirements for secondary daylit zones (Section 140.6(d))
5. Requirements for demand responsive reduction of lighting power being applied to smaller spaces. (Section 130.1(e))
6. Mandatory Automated Lighting Controls and Switching Requirements in Warehouses and Libraries ‐ Require the installation of occupancy sensors in warehouse aisle ways and open spaces, and library stack aisles. (Section 130.1(c)6A & B)
7. Mandatory automated multi‐level lighting shut‐off controls and switching requirements for hotels and multifamily building corridors ‐ Require the installation of occupancy sensors in corridors and stairwells in lodging and multifamily buildings. (Section 130.1(c)6C)
8. New mandatory occupancy sensor and daylighting controls in parking garage spaces. (Section 130.1(d)3)
9. Increased requirements for multi‐level lighting controls for nonresidential outdoor lighting. (Section 130.2(c)3B)
10. Existing outdoor lighting cutoff (shielding) requirements, changed to the new IES standard: Backlight, Uplight, Glare (BUG) requirements. (Section 130.2(b))
