A new efficient method for evaluating the level of coverage of distributed monitoring systems, supporting the recent European standard EN17267 for energy efficiency

Distributed Monitoring Systems (DMS) are essential to implement global policies and daily practices to preserve and improve the energy efficiency of an organization. The Level of Coverage (LoC) is a primary aspect in design, evaluation and implementation/extension of a DMS. The LoC is a numeric indicator representing the ability of a DMS to properly monitor the energy consumption/production in specific Zones and for particular Uses. It allows comparison and choice among several DMS implementations, differing for number and positioning of the measuring instruments. This paper presents a new method for LoC computation. It can be easily implemented in SW and allows to directly calculate not only the LoC of the whole DMS and its subsections but also semi-aggregated LoCs referred to specific Uses or specific Zones. The latter aspect is very useful for assessing the energy monitoring plan adopted in mandatory or voluntary energy audits.
