Central Heating Plant Decentralization Producing Substantial Saving for Years to Come
Located in downtown Frankfort, Kentucky, the Transportation Cabinet Office Building (TCOB) and the State Office Building (SOB) together encompass over 800,000 square feet of office space. When constructed in 2004, the TCOB included a complex hot water heating system in the central utility plant, with capacity to heat an additional two million square feet of future office space. However, plans for the future office space changed and it was never constructed, leaving the State with an over-sized and inefficient heating plant.
Replacing the complex heating plant was not the only challenge that CMTA and the state government faced when analyzing these buildings. The existing boiler’s manufacturer had gone out of business, leaving little improvement options with that unit. The underfloor variable air volume air distribution systems were failing as well. Comfort issues plagued the buildings, with high humidity levels occurring regularly and many offices dealing with hot temperatures.
