October 14, 2005—New energy efficiency standards for both residential and nonresidential buildings took effect on October 1 in California. The changes require duct insulation in commercial buildings and prescribe a variety of energy efficiency measures, including cool roofs, well-sealed ducts, daylighting, and high efficiency heating and cooling.
Most of the mandatory changes relate to indoor and outdoor lighting, encouraging technologies such as fluorescent lights, occupancy sensors, and dimmers.
