Sain Engineering Associates, Inc. (SEA) was recently featured on the front cover of the ASHRAE Journal, September 2020 Issue for innovative technology and work conducted at the ADTRAN East Tower Chiller Plant in Huntsville, Alabama. All savings in the 640,000 square feet tower were gained from modifications to existing equipment and controls that increased efficiency. Since 2005, the EUI has been reduced by 39%.
The ADTRAN East Tower in Huntsville, Ala., used several optimization methods to radically reduce energy use without costly equipment replacements. The project was completed without any capital expenditures; all results were gained strictly from modifications to the existing equipment and controls to increase efficiency. These methods saved over $71,326 annually in energy costs with a simple payback of 1.86 years.
SEA is very proud of our team members, Jason Brooks, P.E., Director of Engineering and Eric Mobley, Energy Engineer who took lead on this project. Special thanks to Kelley Whalen, facilities supervisor – energy management, HVAC & Electrical at ADTRAN for his appreciation and collaboration on the project.
