CEC Approves New Energy Efficiency Standards for Buildings
California is destined to be the location for many more energy efficient buildings, since the California Energy Commission (CEC) has approved updated building standards for energy efficiency. The new standards take effect in October 2005, and will yield more than 500 megawatts in energy savings for the state by 2008. The new standards include the use of "cool roofs" and efficient lighting, as well as measures to encourage greater use of daylighting, better sealing of ducts, and improved window glazing. See the November 5th press release and the new building standards on the CEC Web site.
The upgraded building standards are supported by a recent study of green buildings, which found that green designs typically add about 2 percent extra to the cost of a building, while yielding savings over the life of the building that total 20 percent of the building costs. In other words, the savings are 10 times the initial investment. The study, released in October, was prepared by the Capital E group with help from DOE's Lawrence Berkeley National Laboratory. It was developed for the Sustainable Buildings Task Force, a group of more than 40 California state agencies. See the report on the Capital E Group Web site.
