Sally Wilson, CB Richard Ellis' senior vice president and global director of Environmental Strategy, represented USGBC along with Pat Marr and Chau Leung, also at CBRE. In addition, CBRE's Project Management Team, led by Chris Brown and Dale Martin, assisted on site selection and pre-construction planning. They will represent USGBC during the construction phase of the project as well.

Wilson says that USGBC needed the additional space to accommodate the new staff hires it is planning to make. There were no expansion options at 1800 Massachusetts Ave. USGBC "experienced extreme growth that outpaced all expectations after it relocated to its current headquarters," she says in a prepared statement.

USGBC expects to achieve a LEED Platinum rating for the build out of the interior space of its new space. CBRE's brokerage team and project management group, as well as USGBC's architect, Envision Design and its engineers, GHT, provided the necessary analysis of the building's potential to pursue this level of LEED certification. USGBC will occupy its new space in March 2009. Until then it will occupy for a short period of time 15,000-sf at 1919 M St.
