The Bureau of Overseas Buildings Operations (OBO) announced today that the newly constructed U.S. Embassy in Lusaka, Zambia was awarded the silver level of Leadership in Energy and Environmental Design (LEED®) certification under LEED for New Construction.
The U.S. Embassy is the first building in Zambia to receive LEED certification.
The embassy was designed to reduce energy costs through the installation of a white roof, light colored façade, and sun shades around windows to reduce solar heat gain. Occupancy and daylight sensors automatically turn off overhead lights. Additional energy-efficiency is gained from solar hot water, daylight harvesting, and electric traction elevators.
The building conserves water through the installation of low-flow and low-flush plumbing fixtures. All water consumed is cleansed at an on-site treatment plant, reused for irrigation, and ultimately infiltrated on-site, replenishing the ground water.
The base building materials have a combined recycled content value of 20 percent. Most notably, the rebar contains 98 percent post-consumer recycled content and the gypsum board has 94 percent pre-consumer recycled content.
LEED certified buildings are designed to lower operating costs while increasing asset value, reduce waste sent to landfills, conserve energy and water, be healthier and safer for occupants, and reduce harmful greenhouse gas emissions.
The embassy in Lusaka was constructed by the design-build contractor, B.L. Harbert International of Birmingham, Alabama; Mechanical, Electrical, and Plumbing design was completed by H&A Architects & Engineers of Glen Allen, Virginia; and the architect of record is EYP Architecture & Engineering of Albany, New York.
Since 1999, as part of the Department’s Capital Security Construction Program, OBO has completed 89 new diplomatic facilities and has an additional 43 projects in design and construction. The program has successfully moved more than 27,000 people into new diplomatic facilities, furthering OBO’s mission to provide safe, secure and functional facilities that represent the U.S. Government to the host nation and support our staff in achieving U.S. foreign policy objectives. These facilities should represent American values and the best in American architecture, engineering, technology, sustainability, art, culture, and construction execution.
