The mechanical system design often includes the distribution of air and a refrigerated or heated medium. Pumps and fans are large components of energy usage. Use variable-frequency drive pumps and a variable-air-volume distribution system to address fluctuating demand. Install sensors and controls to maintain air volumes and reduce energy waste during low-occupancy periods.
