The U.S. Embassy in Colombo has proudly earned the Leadership in Energy and Environmental Design (LEED®) Gold certification, marking it as the 50th building in Sri Lanka to achieve this prestigious status. LEED, managed by the U.S. Green Building Council, recognizes outstanding performance in areas such as energy efficiency, water conservation, waste management, and indoor air quality.
This achievement reflects the U.S. government’s ongoing commitment to sustainability, climate resilience, and environmental responsibility, demonstrating the Embassy’s dedication to eco-friendly practices while respecting Sri Lanka’s cultural and ecological heritage.
On the occasion of World Energy Conservation Day on December 14, U.S. Ambassador Julie Chung met with Sri Lanka’s Minister of Environment, Dr. Dhammika Patabendi, and Minister of Energy, Kumara Jayakody, to discuss the Embassy’s innovative, sustainable design. Ambassador Chung emphasized the building’s energy-efficient features, integration of local cultural elements, and its role in addressing global environmental challenges.
“Achieving LEED Gold certification is a significant milestone in our shared sustainability efforts,” said Ambassador Chung. “The Embassy is a symbol of how thoughtful design and green practices can protect the environment while honoring Sri Lanka’s natural and cultural heritage. We are proud to contribute to Sri Lanka’s greener future.”
Minister Patabendi praised the Embassy’s design, noting its energy efficiency, use of native plants, and respect for the local environment. He emphasized that this building sets a high standard for future infrastructure projects, showcasing the positive impact of international cooperation on sustainable development in Sri Lanka.
The U.S. Embassy in Colombo is part of a larger network of U.S. diplomatic missions worldwide that adhere to the U.S. Department of State’s Bureau of Overseas Buildings Operations (OBO) requirements. While OBO mandates LEED Silver certification for new diplomatic facilities, the Embassy’s Gold certification sets it apart, contributing to a global network of 63 U.S. diplomatic missions with LEED certification.
The Embassy was designed with minimal environmental impact in mind. Key features include:
Energy Efficiency: A climate-responsive design with solar panels that reduce energy consumption by 40%. The panels, totaling 194.58 kWp, supply energy to the building and excess power is fed into the city’s grid.
Water Conservation: Advanced stormwater management and wastewater treatment systems recycle water for irrigation, conserving potable water.
Green Spaces: The Embassy grounds feature native Sri Lankan plants, reducing the need for excessive irrigation and creating harmony with the local ecosystem.
Sustainable Transportation: A bicycle-sharing program encourages staff to reduce reliance on motor vehicles.
Efficient Operations: Enhanced commissioning ensures systems are optimized for performance and energy savings.
Recycled Materials: The building incorporates recycled materials to minimize environmental impact.
Indoor Air Quality: Low-emitting paints, coatings, and flooring enhance indoor air quality for occupants.
The Embassy’s achievement serves as a concrete example of how innovative design can reduce energy consumption and promote sustainability. It aligns with the global movement towards greener, more sustainable practices, reaffirming the shared commitment between the United States and Sri Lanka to address climate challenges and protect the environment for future generations.
