Submetering is recognized as a mean to optimize building performance, but can be expensive to implement. New electronically controlled pumps, which need to be there in any case, have a lot of built in functionalities which can be used for submetering. These functionalities were initially developed to control the pump itself, but are today interfacing with the BMS system to optimize building performance. This presentation gives an overview of measurement signals, which are typically available from an electronically controlled pump, the accuracy of these signals and how they can be used for submetering.
