Additional projects through the years include:
- Upgrades to smart building management controls, including data analytics
- Installation of frequency drives on air handling unit motors
- Installation of energy efficient state-of-the-art chillers
- Increased insulation on steam piping systems
- A new, smaller summer boiler for steam
- Lighting upgrades to more efficient bulbs
We performed two large lighting upgrade projects—from T8 fluorescent to LED bulbs—in 2016. The lamp replacements in parking lots will save the Lexington site approximately 280,000 kWh annually. A relamping project performed within a large office space on campus will save an estimated 180,000 kWh annually.
The Facilities department at our headquarters location continues to assess space on campus, identifying unused areas that can be moved into a dormant state to minimize energy usage. Approximately 29,000 square feet of space was taken out of service in 2016. We anticipate a larger savings from closing out 10,000 square feet of data center space due to the reduction of the physical servers occupying this space. Approximately 416 physical servers were decommissioned in 2016, with the data consolidated, virtualized or moved to supplier equipment. The 2016 savings is estimated to be over 591,000 kWh. We are targeting project completion in 2017, with an additional 100 servers scheduled for move or decommission and a projected $140,000 savings due to reduced energy and maintenance needs.
