Opportunities for reducing energy consumption can be identified only if it

is possible to monitor performance of the systems. Good monitoring

systems can allow better control of part load performance, not only

improving efficiency, but also improving the control of the building’s

thermal comfort conditions. Plant control can be altered and the results

monitored to show how energy consumption changes. Unseen plant

faults, which are not evident during routine maintenance, can be

identified from analysis of performance trend data. Control problems can

be detected and control strategies improved to match the building

demand.

The cost of instrumentation is not significant when compared with

installation costs and the accuracy should be such as to provide

meaningful readings. The payback on improved performance can be

very high taking into account the reduction in electricity consumption and

demand charges resulting from more efficient plant operation.
