SAN FRANCISCO--(BUSINESS WIRE)--Crowning an industry-leading, employee-driven green program, 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. Among the energy efficiency steps taken at W San Francisco without negatively impacting the sensory experience and atmosphere of the hotel: More than 70 percent of guestroom lighting and 90 percent of back-of-house lighting is energy efficient, using CFLs, LEDs, motion sensors, and other technologies; the hotel’s HVAC cooling towers were replaced with energy-efficient models, saving 300 kWh/year; motion sensors power off HVAC in unoccupied guestrooms; and ENERGY STAR power management features are activated on all PCs. Management continues to track energy usage and savings with a third-party vendor through the hotel's utility company, PG&E. Lastly, to further improve energy efficiency and encourage the use of renewable energy, management is considering installing wind turbines on the hotel's roof--a first for a commercial building in the city.
