In 2013, Columbia Square was awarded the USGBC LEED-EB® O&M: Gold certification (US Green Building Council’s Leadership in Energy and Environment Design Existing Building, Operations and Maintenance silver certification).

LEED is an internationally recognized green building certification system, providing third-party verification that a building or community was designed and built using strategies aimed at improving performance across all the metrics that matter most: energy savings, water efficiency, CO2 emissions reduction, improved indoor environmental quality, and stewardship of resources and sensitivity to their impacts.

Developed by the U.S. Green Building Council (USGBC), LEED provides building owners and operators with a concise framework for identifying and implementing practical and measurable green building design, construction, operations, and maintenance solutions.

Columbia Square was also honored in 2010 with the USGBC LEED-EB O&M District of Columbia Area Project of the Year for Existing Buildings.
