“Maximize building performance of this historic building…”
Louisville’s transit agency (TARC) set forth great effort to improve energy efficiency and preserve Union Station. The longtime railroad station originally opened in 1891 with TARC taking over the site in 1979. The heating and air-conditioning systems were approximately 30 years in age, rendering upgrades to the systems a priority. Kerr-Greulich Engineers, Inc. consulted on this project for several years assisting to maximize building performance. This particular project consisted of commissioning the mechanical systems. The HVAC system improvements save TARC approximately $60,000 annually on heating costs.
- Tested and adjusted the water source heat pump system to confirm interoperability between cooling towers, pumps, boilers, and prepare the system for future geothermal wells.
- Interlocked dedicated outside air units with heat pump system to ensure energy is not used when unnecessary.
- Verified communication between local equipment and automated control to minimize energy use.
- Measured energy recovery heat transfer and adjusted fans to verify efficiency.
- Adjusted atrium heating and cooling to preserve grandeur of space while providing occupant comfort.
