SSR has been providing a variety of engineering design and consulting services to the William R. Snodgrass Tennessee Tower office building in downtown Nashville, TN for over a decade. That work includes MEP design, building enclosure evaluations, and existing building commissioning services Continuous Commissioning and retro-commissioning.

Continuous Commissioning® is an ongoing process to resolve operating problems, improve comfort, and optimize energy use. Performance is monitored and assistance is provided as needed to maintain continued optimum performance. While the goal of the process is to reduce facility energy usage, the additional benefits include improved comfort, increased occupant productivity, and decreased maintenance costs.

SSR conducted a Phase 1 Building Assessment and completed the implementation of all the measures as part of Phase 2. SSR also provided CC® Phase 3 (ongoing) monitoring service to the office tower to prevent the erosion of savings and identify new measures to be implemented. As part of Phase 3, our team has worked hand in hand with the facility team to resolve ongoing issues in a quick and efficient manner.

Based on the measured energy savings, the activities show continued month over month energy savings. When reviewing the total estimated energy cost savings for the period of January 2013 through March 2021, the energy cost savings come to $3,811,673. In total, approximately 55% of the cumulative savings comes from electricity, 40% comes from district chilled water, and 5% comes from district steam. Over the course of our engagement, SSR’s efforts were able to improve the performance of the facility from an initial Energy Star Score of 34 in 2012 to a score of 76 which allowed the facility to qualify for Energy Star Existing Building Certification.
