GE’s New 40-Watt LED Bulb Will Last 25,000 Hours


CLEVELAND, OHIO—General Electric has unveiled its new 40-watt LED bulb that will last 25 times longer than incandescent bulbs, which are being phased out in the United States. The bulb, part of GE’s Energy Smart line, will last more than 25,000 hours, compared to the typical 1,000-hour lifespan of incandescent bulbs. When used for three hours a day (the average used by Energy Star for comparing bulb performance), the GE 40-watt LED would last close to 23 years.

Hilton Worldwide Unveils LightStay Sustainability Measurement System


MCLEAN, VA.—Following two years of testing, Hilton Worldwide has unveiled LightStay, a proprietary system developed to calculate and analyze environmental impact. In the first full year of findings, the 2009 LightStay results show that the 1,300 Hilton Worldwide properties using the system conserved enough energy to power 5,700 homes for a year, saved enough water to fill more than 650 Olympic-size pools and reduced carbon output equivalent to taking 34,865 cars off the road. Reductions in water and energy use also translated into dollars saved for hotel owners, with estimated savings of more than $29 million in utility costs in 2009. LightStay helped Hilton Worldwide properties using the system reduce energy use by 5 percent, carbon output by 6 percent, waste output by 10 percent and water use by 2.4 percent in 2009 versus 2008. These results have been independently audited and are adjusted for any differences in occupancy levels and major weather events year over year.

Entropy Solutions Introduces PureTemp for HVAC Systems


MINNEAPOLIS—Entropy Solutions, Inc., a Minneapolis-based thermal technology development company, has introduced PureTemp for HVAC (heating, ventilation and air- conditioning). A vegetable oil derivative, PureTemp is a phase change material (PCM) that captures wasted ambient energy, and then releases this energy as necessary to hold specific temperatures for extended periods of time without requiring additional energy.

Constant Airflow Regulators Provide Rapid ROI


BRADENTON, FLA.—At a time when energy costs have reached an all time high, savvy hotel and condo owners are finding highly effective ways to conserve energy and save money. By installing constant airflow regulators in bathroom and kitchen exhaust vents, owners and operators are able to accurately and automatically control the amount of heated or conditioned air that is constantly blown out of their buildings.

U.S. EPA, DOE Announce Changes to Bolster Energy Star Program


WASHINGTON, D.C.—The U.S. Environmental Protection Agency (EPA) and the Department of Energy (DOE) jointly announced changes to the Energy Star product certification process to ensure that only products meeting the program requirements can receive an Energy Star label. These changes accelerate steps DOE and EPA have initiated over the past several months to bolster the verification, testing and enforcement aspects of the Energy Star program. “The Energy Star program started out small and has grown quickly, and now the brand is immensely valuable to consumers and businesses,” said Gina McCarthy, EPA assistant administrator for Air and Radiation. “The safeguards we’re putting into effect are essential for the millions of consumers who rely on Energy Star products to help save energy, money and the environment.” “Consumers trust the Energy Star brand to save them money and reduce carbon pollution,” said Cathy Zoi, DOE assistant secretary for Energy Efficiency and Renewable Energy.

Westin Westminster Announces Plans to Install Solar System


WESTMINSTER, COLO.—The Westin Westminster announced that it will capitalize on Colorado’s 300-plus days of annual sunshine with the installation of a state-of-the-art solar panel system to help provide power to the 369-room hotel. The solar panels, which are scheduled to be installed next month on the roof of the hotel, will produce 42,576 kilowatt-hours per year—the equivalent to planting more than 192 trees annually. The Westin Westminster has applied to receive a grant from the federal government and a solar rebate from Xcel Energy. The 32-kilowatt solar system features 139 panels that are being installed by Integral Energy Systems of Golden.

W Hotel in San Francisco Earns LEED Silver Certification


SAN FRANCISCO—The four-diamond W San Francisco made history this week by earning the first LEED certification of an existing building belonging to a major hotel brand. With its Silver LEED certification, W San Francisco becomes only the seventh hotel in the United States to receive the recognition for an existing building. Stringent criteria for an existing building certification measure “operations, improvements and maintenance on a consistent scale, with the goal of maximizing operational efficiency while minimizing environmental impacts,” according to the U.S. Green Building Council, which administers the LEED program. Certified by the state of California as a green business, W San Francisco began its green program in 2007 with the passion of employees helping launch it. W San Francisco also won a 2008 “Good Earthkeeping” award, recognizing environmental leadership, from the California Hotel & Lodging Association.

Harrah’s Rincon Uses Solar Energy to Offset Portion of Energy Consumption


VALLEY CENTER, CALIF.—The Rincon Band of Luiseno Indians announced the completion of a 1 Megawatt solar plant that provides enough power to run approximately 90 percent of the Harrah’s Rincon Casino & Resort’s heating ventilation and air-conditioning (HVAC). The plant reduces grid consumption, curtailing enough energy to power about 2,200 homes. The 3,936-panel solar field, which was manufactured and installed by Suntech, will produce enough energy to offset almost a quarter of the casino’s total power consumption. Bo Mazzetti, chairman of the Rincon Band of Luiseno Indians, said he is grateful for the leadership that the Harrah’s Rincon team and the Rincon Tribal Council have shown in creating a green initiative. As part of this project, the casino’s HVAC system moved from packaged units to a chilled water unit with heat recovery capability, resulting in an estimated savings of 3.3 million kilowatt-hours per year.
