Our Projects

SIG boasts an impressive 100% hit rate for target certification levels. There are no projects too small or large for us as we have worked on everything ranging from single-office tenant buildouts (commercial interiors) to professional sports stadiums and the largest LEED certified convention center in the world. To date, we have worked on over 400 LEED projects and 56 million sf of engineering (Cx, RCx, energy modeling, energy auditing, and ENERGY STAR benchmarking) projects.

“SIG has been amazing in giving me the tools, education AND attention in training me for the LEED Green Associate exam. I couldn’t have asked for a better tool for learning and studying for this test. I look forward to working with them on continuing my education on all things LEED!”

Roni Page-Dowdy, Major Accounts & RME Program Manager Waste Pro/Atlanta Doraville, GA

“Sustainability is very important to our portfolio and SIG has been a huge part of this effort along the way. As an Owner and Operator, we were looking for a full-service consulting firm that could be our partner to achieve these sustainability initiatives. SIG has and continues to guide us with LEED EB Consulting (initial and recertification), Retro-Commissioning, Energy Auditing, ENERGY STAR PE Verification, GRESB support, Tenant Education, Staff Training, and regular Sustainability Reporting, and even occasional Waste Audits. I highly recommend SIG. They really do it all in-house and are easy to work with.”

Paul Hitzel, Director of Engineering Paramount Group, Inc. New York, NY | Washington, D.C. | San Francisco, CA

“Working with SIG for the last three years has been a great experience that has resulted in an exceptional working relationship, improved building operational performance, and, through their guidance, becoming the world’s largest LEED certified convention center.”

Tim Trefzer, Sustainability Manager Georgia World Congress Center Authority Atlanta, GA
