BMS Functions: Trending, Alarming, Scheduling

A Building Management System's real value to an energy manager is not that it controls plant but that it watches, records and reports on everything the building does. The thousands of points it logs turn hunches into evidence: instead of "the chillers feel like they run too much", you get a chart proving they run at 150 kW through an empty building every night. Three functions do this work: trending, alarming and scheduling. This lesson covers each and the discipline that makes them useful rather than ignored.
