U.S. Embassy Colombo announces the achievement of Leadership in Energy and Environmental Design (LEED®) Gold certification, becoming the 50th building in Sri Lanka to earn this globally recognized symbol of sustainability achievement. The U.S. Green Building Council's LEED green building program recognizes energy efficiency, water management, waste reduction, and indoor environmental quality execution in the built environment.
This milestone demonstrates the United States’ commitment to sustainability and climate resiliency in practice, the Embassy’s commitment to environmental stewardship, and respect for Sri Lanka’s ecology, history, and culture.
To commemorate this accomplishment and in anticipation of World Energy Conservation Day on December 14, U.S. Ambassador Julie Chung recently met with Sri Lanka’s Minister of Environment, Dr. Dhammika Patabendi and Minister of Energy Kumara Jayakody to discuss the Embassy’s state-of-the-art facilities. The Ambassador emphasized the building’s innovative energy-efficient design, the integration of local elements, and the importance of sustainable practices in addressing global environmental challenges.
“Achieving LEED Gold certification is a significant step in demonstrating our shared commitment to sustainability,” said U.S. Ambassador Julie Chung. “This building is more than an Embassy—it’s a symbol of how thoughtful design and green practices can protect our environment while honoring Sri Lanka’s cultural and natural heritage. We are proud to stand as the 50th LEED Gold certified building in the country, contributing to Sri Lanka’s greener future.”
Minister Patabendi stated, “The U.S. Embassy achieving LEED Gold certification is a significant milestone in sustainable infrastructure development. This building exemplifies innovative design, energy efficiency, and respect for our local environment through the use of native plants and integration of local artistry. It sets a benchmark for future projects and highlights the positive impact of international collaboration in advancing sustainability goals in Sri Lanka. It reflects the strong partnership between the United States and Sri Lanka and demonstrates how thoughtful design can benefit both the environment and the community.”
The U.S. government overseas diplomatic and consular property portfolio, managed by the U.S. Department of State Bureau of Overseas Buildings Operations (OBO), mandates LEED Silver certification for the construction of new facilities. U.S. Embassy Colombo joins 63 U.S. diplomatic missions worldwide that have achieved LEED certification, of which 23 are certified Gold, 17 of which were the first LEED certification in the country.
Building Performance Highlights:
The U.S. Embassy in Colombo was designed to minimize environmental impact while showcasing the rich culture and biodiversity of Sri Lanka:
- Energy Efficiency: The climate-responsive shell, deep roof overhangs, sunscreens, and a green roof reduce solar heat gain and subsequent energy use for cooling the building. Solar panels contribute to a 40% reduction in annual energy consumption. Solar panels on the roof of the U.S. Embassy warehouse and parking lot have a total capacity of 194.58 kWp. The system efficiently supplies power to the building’s distribution network, and when production exceeds the Embassy’s consumption needs, the surplus energy is fed back into the surrounding city power grid.
- Water Conservation: Advanced stormwater management and on-site wastewater treatment systems recycle gray water for irrigation conserving potable water.
- Green Spaces: Embassy grounds include native Sri Lankan trees and plants, creating a harmonious connection with the local environment and reducing the need for excess irrigation.
- Transportation: A popular staff bicycle-sharing program reduces the reliance on motor vehicles for short trips.
- Enhanced Commissioning: The enhanced commissioning process ensures all systems operate efficiently and as intended to optimize performance and reduce energy consumption.
- Use of Recycled Content: Incorporating materials with recycled content minimizes environmental impact.
- Low-Emitting Materials: Utilizing low-emitting paints, coatings, and flooring systems improves indoor air quality.
World Energy Conservation Day, observed annually on December 14, raises awareness about the critical need to reduce energy consumption and transition to sustainable energy practices. The Embassy’s LEED Gold certification serves as a tangible example of innovative approaches to energy conservation and performance efficiencies and reaffirms the shared values between the United States and Sri Lanka in building a greener, more sustainable future.
