By installing control instructions in a computer and connecting it to each piece of equipment, a building facility operator can use the computer to consistently implement control strategies pertaining to utility consumption. This essentially is what is known as an Energy Monitoring and Control System EMCS. Typically, the building owner insists that the reduction in utility costs after the few years exceeds, or pays back, the installation cost of the EMCS. Due to the high cost of minicomputer equipment, early systems could only have one computer that was remoted through a communications network to many nearby buildings. However, inexpensive but capable microcomputers are available that can provide control for a single building. This report explores the desireability and cost of an EMCS system in general and of these two alternatives in particular. It is found that the quickest payback was found in systems implementing the fewest number oof control strategies. Further, it appears that choice of a network over a single building control system depends on the number of buildings connected.
