The Westin Bonaventure here has received Los Angeles’ first Green Seal Silver Certification, making it the largest environmentally responsible hotel in the city. The 1,354-room hotel earned the certification as a result of implementing a variety of energy-saving and waste reduction initiatives that management estimates will save the property approximately $225,000 each year. The Green Seal Silver Certificate is awarded through Green Seal, an independent environmental non-profit based in Washington, D.C. Green Seal works in partnership with the City of Los Angeles’ Green Lodging program, LA INC/The Los Angeles Convention and Visitors Bureau and City Councilmember Richard Alarcón. "We consider ‘greening’ the hotel to be our responsibility," said Michael Czarcinski, managing director of the Westin Bonaventure. "By implementing these programs and monitoring them, we’re reinforcing that wasting resources is not an option. While some of these initiatives may seem simple, they’ve already made a noticeable difference in our energy use and waste output. The flick of a light switch is more significant than you think-particularly in a hotel of this size. This is not something that’s optional or just a trend. We’re in a position to make a great deal of difference by reducing our carbon footprint." By 2012, the hotel will have replaced all existing guestroom water fixtures with water conserving fixtures, including faucets, aerators, showers, toilets and waterless urinals, saving as much as 10 million gallons of water per year. Light sensors, currently operating in all 27 meeting rooms, also will be added to all hotel linen closets during the next five years.
