Performance Measurement System

Performance improvement starts with measurements which are aimed at quantifying past actions in order to determine current performance. Only when performance is quantified, can meaningful discussion about possible improvements begin. The basic principle of EEMS is that the use of energy and other resources must be measured regularly at the point of use and be related to activities that consume the energy or a resource. This is the foundation for energy and environmental performance monitoring and improvement. Energy and environmental managers require the means for determining whether specific energy and environmental performance improvement objectives are accomplished. A performance measurement system (PMS), tailored to the specific process or a part of it, provides such a mechanism and alerts managers to the problems that are developing, by measuring, collecting, processing and structuring performance data on all key activities that ultimately drive the company's profit.

Therefore, EEM will need to incorporate a performance measurement system that will provide direct and timely information on the actual consumption of resources at the point of use, so that needed adjustments can be made to achieve optimized energy and environmental performance.

Many companies produce loads of data that serve no useful purpose because they are not or cannot be converted into valuable information. Data or information is useful only if people can relate them to the performance of a process they are responsible for and if they know how their actions can influence performance. An effective PMS begins with the definition of relevant data, which in our case would be:

• raw materials input;

• production outputs;

• intermediary stocks;

• process parameters (pressure, temperature...);

• all types of energy consumption (electricity [kWh], fuels [liters, tons, m3], water [m3], steam [tons], compressed air [liters or m3]).

This is then complemented by defining how data is:
