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 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.
