Columbus Public Library

A three story library including a 5,100 square foot grand reading room, children’s collection, young adult section with computer area and special reading materials, conference rooms, computer training room, a 150 seat auditorium, a cafe, and an eighty-eight foot tall circular atrium rotunda.


Mechanical and electrical systems noise and vibration control for a three story library.


The facility is air conditioned by 17 geothermal heat pump systems ranging from 5 to 30 tons each, for a total of approximately 325 tons. The heat pumps are equipped with multiple compressors, internal inline pumps, and fans with variable frequency drives that supply conditioned air to 83 variable volume zone dampers. A computerized control system monitors and controls the variable volume zone dampers to maintain space temperature, and switches the heat pumps from cooling to heating mode when required. During the cooling season, the heat is rejected to an earth loop through 168 vertical wells that are 435 feet deep and 20 feet apart.
