Green Building Services, Inc.


Green Building Services, Inc. (GBS) is one of the premier sustainability consulting firms in the United States, and a nationally recognized leader in achieving LEED certification for existing buildings and new construction projects. Conceived in 2000 and headquartered in Portland, Oregon, we are a unique multidisciplinary firm comprised of architects, engineers, interior designers, planners and other professionals. The firm formally incorporated as a “C Corporation” in 2005 in Oregon, and currently has 20 full time employees. We are a woman-led firm, headed by president Elaine Aye, IIDA, LEED Fellow. Our work takes us around the country and internationally, and we have had the pleasure of working with Hines and on LEED Volume projects.

GBS has a long track record of successfully addressing complex green building and facility management challenges. In 2014, GBS achieved the milestone of having consulted in the LEED certification of over 500 projects worldwide, recognized by Richard Fedrizzi, Founding Chair of the U.S. Green Building Council (USGBC) as an amazing demonstration of leadership and having a powerful impact on the built environment, and representing 2% of the green buildings on the planet. We have served as a Gold member and partner of the USGBC since 1997, and became a LEED Platinum member in 2015. We are also a USGBC Education Partner.

In addition to LEED, we are familiar with numerous alternate national and international sustainability rating systems, such as APEX/ ASTM for Sustainable Meeting Spaces, Living Building Challenge, Green Globes, Salmon-Safe and WELL Building. We guide clients towards a certification system that best meets their individual needs and project goals. We are known for providing services and tools to design, construct, and operate buildings and communities that are responsible, enduring, and healthy. From vision development, to site selection through design, all the way through construction and occupancy, we understand the challenges and opportunities at each phase of the sustainability planning process.

Numerous private and public clients have sought GBS’ services for streamlining the achievement of green building goals. We are recognized for specializing in cost-effective energy conservation strategies that go straight to the bottom line.
