Sabey Data Centers has once again cemented its reputation as a leader in sustainable digital infrastructure, earning the prestigious 2025 Green Lease Leaders Gold recognition from the Institute for Market Transformation and the U.S. Department of Energy’s Better Buildings Alliance. This marks the third year in a row that Sabey has received this honor, reinforcing its reputation for integrating environmental stewardship into every layer of its business operations.
The Green Lease Leaders program spotlights organizations that go beyond conventional leasing to embed sustainability and energy efficiency into their agreements. Sabey’s approach is notable for its focus on fostering strong partnerships with tenants, ensuring that both parties are aligned in their commitment to reducing energy use and environmental impact. By weaving sustainability into the leasing process, Sabey helps tenants participate directly in energy conservation efforts, setting a collaborative tone for the entire industry.
This recognition comes at a time of expansion for Sabey, which continues to grow its data center footprint while prioritizing environmentally responsible practices. In Northern Virginia, construction is underway on Building A, the final facility on Sabey’s Ashburn campus. This new building will initially provide 18MW of power, with plans to scale up to 54MW, and is designed to support high-density workloads and advanced cooling systems. The Ashburn project is just one example of how Sabey is meeting the growing demand for data processing power without compromising on sustainability.
Sabey is also making significant investments in the Pacific Northwest. Earlier this year, the company announced expansions to its Seattle and Columbia campuses, both of which display Sabey’s ongoing dedication to efficiency and environmental responsibility. The Seattle campus is powered by 100% carbon-free electricity from Seattle City Light and delivers strong energy efficiency with an average annualized power utilization effectiveness ratio (PUE) of approximately 1.5. The Columbia Campus, known for its low-cost, renewable hydropower, has an average annualized Power Usage Effectiveness (PUE) of 1.2.
Sabey’s continued recognition as a Green Lease Leader is particularly significant as the data center sector faces increasing energy and sustainability regulations. With global demand for digital services driving rapid industry growth, operators are under pressure to adopt greener practices and report transparently on their progress. Sabey’s leadership in sustainable leasing and facility design positions it at the forefront of these industry trends, offering a model for how data centers can scale responsibly while supporting and staying ahead of the world’s digital needs.
