The Directors Guild of America’s headquarters building in Los Angeles has received a silver Leadership in Energy and Environmental Design certification from the U.S. Green Building Council.

The DGA made the announcement Monday, noting that its national board decided a few years ago to begin a long-term effort to examine and upgrade the building’s operations and theaters to become more environmentally conscious.

“The changes and improvements to our facilities and operations will be meaningful not just to DGA members, but to the many members of the entertainment community who use our state-of-the-art theaters to host premieres, screenings, receptions and other events,” said Marcel Giacusa, assistant exec director of national operations. “Now our theaters and public facilities are not only the best in town, they are among the greenest.” The DGA said it’s reduced water use in all plumbing fixtures by 46%; enacted a recycling/solid waste management policy that will divert 42.5 tons of waste from landfills within a year; reduced energy usage by 214,848 kilowatt hours over 2-year period; and reduced particulates in building air distribution systems through the use of high-efficiency filters.
