Regional Library, Hillsborough County (Tampa, FL)
Mold growth on books and odors at the Hillsborough County Regional Library prompted an investigation of the building envelope and air-conditioning system. Advantek expertly pinpointed the causative factors and provided cost effective, energy efficient solutions. The main factors were several small roof leaks, leakage of untreated outdoor air into the return air plenum and air handlers, and high cooling coil temperatures. The HVAC system was delivering less than half of its rated dehumidification capacity. Corrective actions included replacement of one air handler, modification and refurbishment of the other two air handlers, sealing of air leaks, a compressor upgrade, and improved filtration. The Library is enjoying clean, crisp air along with significant energy savings.
