System and method for monitoring electrical demand performance, particularly using historical data and an outside temperature
First Claim
1. A method for monitoring and improving electrical demand performance comprising:
- compiling historical data, the historical data including a building electrical demand and an outside temperature;
obtaining a forecast high temperature for a baseline day;
selecting a control group from the historical data and the forecast high temperature for the baseline day;
calculating an expected demand range; and
providing an alert to building engineers when demand falls outside the expected demand range.

Abstract
A method and associated system for monitoring electrical demand performance in a building, industrial complex or university campus is disclosed. According to a preferred method, historical data is initially complied and statically analyzed to determine demand forecast for a baseline day. Further according to the method, electrical demand is plotted with another indication, more particularly outside air temperature. Additionally the invention provides an electronic alert to building engineers when demand falls outside the expected demand range. Still further a control chart is provided with the expected electrical load range. Outside air temperature is also optionally considered historically and in real time in the method. The invention further contemplates commissioning building engineers to reduce demand when a real time demand is higher than an expected energy demand. A system is also disclosed herein having instrumentation and electronic devices controlled by software and transmitting data.
