Abstract
ABSTRACT This article describes a technique to monitor and analyze daily energy use patterns and develop a daily energy use index (DEUI) as an operations target. The technique can also identify abnormal daily energy use of buildings, plants, and processes. The technique is to use daily use meter readings, statistically analyze them, and use the average of a statistically significant number of readings as a DEUI. The daily use readings can be used with statistical process control (SPC) techniques to calculate the upper and lower control limits (DEUI range). These are used to detect unusual energy use from operations and provide an indicator for immediate investigation and correction by building or process operators.
