The Insufficient Capacity of the HVAC system in the original GMD Building of Collier County

Abstract

Collier County is located in the Southwest of Florida. The Collier family constructed the Growth Management Division Building in 1989, which was bought by the County to establish government offices. Through the years, visitors and employees have complaint of drastic temperature fluctuations in areas of the building. Investments are made annually by replacing rooftop units without success. A mechanical engineer is contracted to study the situation, verify complaints and solve the problem. Analysis and studies concluded that the original installation of the heating, ventilating and air conditioning system was deficient, and improvements made to the offices also have affected its capacity. A new design of a heating ventilating and air conditioning system occurred and rooftop units are replaced by air cooled chillers due to ease of maintenance and City code regulations. Construction will occur during the night, so public services will not be affected. Employees and directors are aware of possible inconveniences.
