The World Bank, I-Building LEED-EB PDF Print E-mail

LEED Project Overview:

The “I” Building, constructed in 1979, is a 477,500 square foot office building located in downtown Washington, DC. The building is owned by The World Bank and managed by internal staff. The property management team and the building owner were motivated to expand and highlight the already "green" components and management practices of the facility. The LEED for Existing Buildings Gold level score of 75 provided a recognizable metric for showcasing The World Bank’s sustainable practices.

The World Bank contracted with Leonardo Academy in April of 2010 to perform an assessment to explore what would be needed to meet the LEED-EB requirements at varying certification levels. After consideration of the assessment analysis, it was determined the building would strive for LEED Gold certification with Leonardo Academy providing consulting services. The LEED-EB O+M implementation effort began in September 2010. The project had a four-month performance period that lasted from September 1, 2010 to December 31, 2010. The building was awarded LEED-EB O+M v2009 Gold Certification in June 2011.
