In recognition of the Department’s commitment to environmental leadership and sustainable design, the new U.S. Embassy in Maputo, Mozambique, achieved Leadership in Energy and Environmental Design (LEED®) Gold certification from the United States Green Building Council.

Designed in collaboration by YGH + Integrus Architecture and Allied Works Architecture, both of Portland, Oregon, and constructed by Pernix Group, Inc. of Lombard, Illinois, the new embassy provides a secure, innovative, sustainable, and resilient platform for U.S. diplomacy in Mozambique. The campus models the latest energy-efficient strategies through an ultra-high-performance concrete fin-shade system that surrounds the building to reduce solar heat gain, as well as its use of low-flow plumbing fixtures, LED installations with daylighting controls, and a solar hot-water system. Energy-conservation strategies reduce the embassy’s electricity use to 24 percent below international benchmarks. In addition, innovative stormwater management solutions enhance the resilience of the campus and neighborhood by mitigating seasonal flooding.

The embassy in Maputo was completed in 2021 and joins 60 U.S. diplomatic missions worldwide that have achieved LEED certification: three Platinum, 21 Gold, and 36 Silver or LEED-certified missions.
