Question 11

During the initial planning phase of an energy audit for a large manufacturing facility, an auditor identifies that a key energy performance indicator (EnPI) for compressed air usage, defined as $ \text{Energy Consumption per Unit of Production} $ (in kWh/unit), relies on a variable representing the average operating pressure of the compressed air system. However, the facility\'s existing monitoring system only records the total runtime of the compressors and the total energy consumed by the compressed air system, without a continuous measurement of system pressure. Analysis of historical data reveals that system pressure fluctuates significantly due to varying demand and maintenance practices, and these fluctuations are not captured by the current instrumentation. What is the most appropriate course of action for the energy auditor in this scenario, according to the principles of ISO 50002:2014?

Accepted Answer

Document the deficiency in the monitoring of the compressed air system pressure as a non-conformity and recommend the implementation of a continuous pressure monitoring system to ensure the EnPI's validity.
