Oh ya - LA has it's own Codes. Building, Electrical, Mechanical, Plumbing, F/L/S, ADA, and such.
There's City of Los Angeles Codes, and County of Los Angeles Codes.
These are based on the California Codes - falling within "Title 24" [parts 1 thru 8].
I think San Diego also has their own Codes. I'm sure they have an Electrical Code [based on CEC / Title 24], but unsure if there's anything else.
They tend to restrict exterior Commercial Lighting to be LPS [Low Pressure Sodium]. The reasons I have heard are:
[*]Reduction of Lighting Power - per Title 24 part 6 energy calcs,
[*]Reduction of Ambient light and resulting light distortions, per Palomar Observatory (Telescopes).
As far as a Common use of the CEC, I can name one very commonly applied CEC item that all Electrical Contractors in California can relate to, along with Electrical Engineers involved with Commercial projects:
California Energy Conservation Calculations / Requirements!!! [AKA Title 24, part 6].
This translates [per Commercial projects] to:
- Electronic Ballasts driving T8 lamps,
- "Bi-Level" or "a/b" switching,
- Bypass switches,
- Energy Calcs on plansets,
- Motion Sensors in Offices and such,
- A maximum of 1.6 Watts per Square Foot of Lighting Power,
- The old "Slave/Master" control for 3 lamp fixtures.
