NEW YORK, March 18, 2013 /PRNewswire/ -- Newmark Grubb Knight Frank (NGKF) Property Management Services employees and clients will join millions of people across 152 countries and territories in switching lights off for an hour to show unified concern for and commitment to the environment. Now in its seventh year, Earth Hour will take place on Saturday, March 23, 2013, from 8:30 p.m. to 9:30 p.m. local time. (Logo: http://photos.prnewswire.com/prnh/20120821/MM60819LOGO ) The largest symbolic mass participation event in the world, Earth Hour promotes awareness and inspires environmentally responsible actions that endure beyond a single day. NGKF's property management professionals will support Earth Hour 2013 by turning off non-essential lights and electrical equipment in its U.S. offices and encouraging tenants in the properties they manage on behalf of clients to participate. "We recognize the importance of treating our natural resources with the greatest respect so they remain available for future generations," said Randy Buddemeyer, president of NGKF Property Management Services. "Strategies to maximize energy efficiency, recycle materials and limit waste are an integral component of our management efforts and, if implemented correctly, can also result in measurable cost savings. We are proud to unite with others who recognize the importance of environmentally responsible practices." In addition to powering down equipment and lights on March 23, NGKF is asking its property management professionals, property owners and tenants to think beyond the hour and pledge their support through Earth Hour's "I Will If You Will" campaign. I Will If You Will fosters greater participation, inspiring family, friends, colleagues or even entire organizations to take ongoing, positive steps to protect the planet, such as planting a tree, refusing plastic water bottles or biking to work. For dozens of NGKF professionals who have earned the LEED AP, LEED Green Associate, Green Advantage, Certified Green Broker, Certified Energy Management Professional and/or Renewable Energy Professional designations, environmentally responsible practices are top of mind every day. These professionals work with NGKF clients to ensure building owners and tenants understand and implement sustainable solutions at their buildings.
