I had the opportunity to attend a California Title 24: Building Energy Efficiency Standards Seminar at Acuity Brands Center for Light & Space in Berkeley. This seminar focused on the upcoming changes to the CA Title 24 lighting requirements which will take effect in 2014. Essentially the standards will be adding layers of control to the lighting systems. So that when a space is unoccupied, energy isn’t being wasted. This isn’t just the use of adding occupancy sensors. It is also adding multi-level lighting controls so lights have different settings and light levels for different activities. To get more specialized you could do automatic day lighting controls or demand response controls. This allows lighting to be adjusted during the peak hours of a day or having a central hub where you can control light settings. There is a lot of information and a professional would be able to help navigate you through the requirements. This may seem like a nuisance which costs more money, but when you see the figures, in the long run you end up saving money.
For more information and specifics on the changes, review What's New in the 2013 Code from California Lighting Technology Center.
