Energy Performance Indicators (EPI) are the basis for the implementation of an energy management system. The EPIs, particularly at industrial sites, further measure the ratio between electricity consumption and production usage. Qualisteo implements customised IPEs, corrected for influential factors such as temperature, plant activity, production, etc.

The IPEs proposed by Qualisteo vary according to the operation of the sites, particularly industrial sites, and are designed to highlight Significant Energy Uses (SEU). ESUs are proposed on a macro scale at the plant level (kWh based on the overall production of the site) or on a micro scale (COP of a chiller, kWh per production line, kWh/tonne produced).

The monitoring of IPEs and UESs makes it possible to optimise consumption more finely in order to obtain better results, to communicate in a structured way to the user the information he needs and, finally, to alert in the event of consumption drift.
