Sequence of Operation

Energy Efficiency and the Sequence of Operation

The Sequence of Operation is the organizing narration of the facility's integrated EMCS functions that will determine the ability of the laboratory to perform in an energy-efficient manner. The importance of describing the function of the laboratory facility's environmental systems with detailed, comprehensive control strategies cannot be overemphasized. Topics that affect energy efficiency and should be addressed by the sequence of operation control strategies include:

·systems and equipment controlled;

·system initiation;

·modes of operation, cooling heating, ventilation;

·occupied periods;

·unoccupied periods;

·set points for temperature, pressure, humidity;

·set-back routines;

·optimal starts;

·time limited control of equipment;

·override sequences;

·alarm point ranges; and

·control vs. monitoring point descriptions.
