WATT PLAZA BECOMES FIRST OFFICE BUILDING IN LOS ANGELES TO RECEIVE
PRESTIGIOUS GOLD LEED® CERTIFICATION IN
‘EXISTING BUILDINGS OPERATIONS AND MAINTENANCE’ CATEGORY

CENTURY CITY, Calif. (May 19, 2009) —Watt Plaza, a twin 23-story office tower complex encompassing
900,000 square feet in the heart of Century City, has been awarded Gold LEED Existing Buildings
Operations and Maintenance (EB O&M) certification by the U.S. Green Building Council, making it the first
office building in Los Angeles to achieve this distinction in this category.

Watt Plaza is one of five buildings in California and one of 12 buildings in the United States to be certified
LEED EB O&M. LEED, which stands for Leadership in Energy and Environmental Design, is the U.S. Green
Building Council’s primary rating system for designing and constructing the world’s greenest, most energy
efficient and high-performing buildings.

LEED Certification of Watt Plaza was based on a number of green measures taken to positively impact the
project itself, the broader community and reduce global climate change. These measures include: water
conversation, waste recovery, alternative transportation options, energy efficiency measures, and an
indoor air quality management program.
