Thoughts on California Green Lighting Requirements

Tech Notes

Just recently came across a site ( that’s chockful of wonderful information for navigating through California’s Title 24 (green lighting) requirements. One of our dealers was gracious enough to send me the link.

CLTC (California Lighting Technology Center) which developed the Residential Lighting Design Guide should be commended for getting this information on the web. The guide mentions 3 key energy efficient lighting technologies that in general will satisfy the new Title 24 rquirements. They are:

  • Sensors: Occupancy sensors, vacancy sensors, motion sensors and daylight sensors are all devices that automatically turn off the lights in response to conditions that they “sense” or “see”. Automation controllers like the HAI Omni and Elk M1G can be programmed to use burglary alarm motion sensors as occupancy/vacancy/daylight sensors.
  • High-efficacy luminaires: These lighting fixtures are designed and built to operate only energy-efficient light sources, such as fluorescent T8 lamps, compact fluorecent lamps (CFLs) and high intensity discharge (HID) lamps. Not all CFLs are title 24 compliant especially those that work with incandescent fixtures (screw-in) because of the type of ballast (magnetic) that they use. Note: as of 2/08/06 it is unlawful for California residents to dispose of any lamps containing mercury in the regular weekly garbage pickup conducted for homes and businesses. Check out for disposal locations in CA and for the rest of the nation.
  • Dimmers: Probably the easiest to accommodate in a lighting plan for Title 24 requirements. Communicating and remotely controlled dimmer switches add another level of energy savings. By varying the ON ramp rates and light levels, bulb life is greatly increased and energy usage is slashed.

Although not included in Title 24 requirements, landscape lighting can often be made energy conscious as well through the use of dimmable, controllable switches. Coupled with automation controllers, the use of these switches in the home will give the homeowner the quickest return on investment.

Although the main focus of these requirements is to enforce energy efficiency in newer home construction, we can definitely use similar approaches in a retrofit application.

  1. Hey thanks for your insight on automation systems and lighting control as it pertains to California’s Title 24. NY legislation is not quite as stringent about energy conservation just yet, but our company is slowly working on fusing sophisticated home theater and lighting control technology with modest energy bills thanks to Control4. Feel free to check us out on the web at

  2. Thanks for the comments. California is at the forefront of energy conservation as a matter of necessity. Unlike NY, CA does not have sources of power like hydroelectric dams. With the ever increasing price of oil and presumably natural gas which powers most of CA’s power generation plants, the state is mandating these stringent Title 24 requirements. Control4 is one of many Home Automation device manufacturers that can help us do our fair share in conserving energy resources.
