18. HVAC Distribution Systems: Contractor shall use variable frequency drives for chillers, fans, pumps and motors. Air Conditioning should be designed first to control humidity and air quality, then to cool.

Variable Air Volume systems with desiccant dehumidification and with cooling and UV-C emitters, controlled by DDC and humidistat, and thermostat in each room/zone are preferred. Size fans and pumps properly to meet the loads without excessively over sizing. Select equipment with a cooling capacity closest to the design load (no safety factors) meeting the conditions of ETL 04-3. Over sizing of cooling equipment inhibits dehumidification capability. (Heating equipment capacity should include appropriate safety factors.) Select equipment that will meet the design requirements and provide the lowest life cycle cost and energy consumption.

19.8 Interlock all exhaust fans with HVAC control system. These fans should not run after hours when

HVAC system is down. Running will cause a slight negative pressure on building which will allow for infiltration through voids in the building shell.

19.9 Use of round ductwork wherever, whenever possible, as directed by ASHRAE 90.1-2010. Will reduce leakage, friction, and BHP on AHU fan, thus improving overall system efficiency and performance.

19.10 Provide UV-C emitters at each air handler, fancoil unit, and packaged ACU over 5 Tons to maximize IAQ and minimize need for duct cleaning and energy loss due to clogged filters and coils.
