Abstract: A Process Energy Intensity Monitoring and Diagnostic System designed to evaluate the amount of energy input into a process and the resulting product output, and comparing the resulting energy intensity (energy per unit produced) calculation with a statistical average, or preferred value. Further, the system will isolate energy intensity data points that occur outside statistically derived upper or lower control limits. The system will collect information from specific equipment within a manufacturing or production process. This information will be transmitted to the central database that will store, calculate, and deliver real time and historical consumption, production, and energy intensity data to connected client devices. Client devices may include computers, smartphones, or web browsers.
