On the Horizon and Here Today: LED Alternatives to Linear Fluorescents
March 4, 2008 09:08 AM - Glenn Hasek, Green Lodging News

NATIONAL REPORT—In meeting rooms, back of house and other areas of your hotel, chances are great that you are using T-12 fluorescent lamps or the more efficient T-8s to illuminate large spaces. At least two companies—ilumisys, Inc. in Troy, Mich., and LEDdynamics, Inc. in Randolph, Vt.—are trying to replace these linear fluorescents with LED alternatives that are more energy efficient and safer for the environment. Fluorescent tubes include mercury and despite recycling efforts, 500 million to 600 million lamps end up in landfills each year. LED alternatives do not include mercury.

Revolutionary Vacuum Glass Coming from Guardian

Guardian Industries, one of the world’s largest architectural and automotive glass manufacturers, with 19,000 employees in 25 countries, has under development a revolutionary vacuum-glazing panel that provides a center-of-glass insulating value of R-12 to R-13. The glass—Guardian VIG (for vacuum-insulated glass)—has a very thin (250-micron or 0.25-mm) space evacuated to 10—4 torr (for reference, thermos bottles typically have a much harder vacuum of around 10—6 torr) between two layers of glass, one of which has a low-emissivity (low-e) coating. Guardian is currently producing the vacuum glazing on a limited basis for testing and hopes to roll it out commercially by the end of 2009.

Gravity powered lamp generates as much light as 40 Watt bulb
February 22, 2008 09:36 AM - ENN

Clay Moulton of Springfield, Va., who received his Master of Science in Architecture with a concentration in industrial design from the College of Architecture and Urban Studies in 2007, created the lamp as a part of this master’s thesis. The LED lamp, named Gravia, has just won second place in the Greener Gadgets Design Competition as part of the Greener Gadgets Conference in New York City. Concept illustrations of Gravia depict an acrylic column a little over four feet high. The entire column glows when activated. The electricity is generated by the slow fall of a mass that spins a rotor. The resulting energy powers 10 high-output LEDs that fire into the acrylic lens, creating a diffuse light. The operation is silent and the housing is elegant and cord free — completely independent of electrical infrastructure.

Although LED bulbs for residential and commercial applications are not quite where they need to be, they are starting to scratch their way into the market this year with more force than ever before.

California to Require Net-Zero-Energy Buildings
February 5, 2008 10:11 AM - , BuildingGreen

Every two years, the California Energy Commission (CEC) releases an Integrated Energy Policy Report in which it makes recommendations for energy policy in the state, including changes to Title 24, the energy efficiency portion of the building codes. In its 2007 report, CEC recommends adjusting Title 24 to require net-zero-energy performance in residential buildings by 2020 and in commercial buildings by 2030. According to Panama Bartholomy of CEC, the commission does not need new legislation to incorporate these goals and is already moving to put them in place. “The 2008 standards will get us closer to these recommendations,” he said, referring to the Title 24 update currently moving through the state’s rulemaking process.
