Daily Energy Use Index (DEUI) Using Daily Meter Readings to Improve Operating Efficiency for Buildings, Plants, and Processes
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.
