A controller for a building management system is configured to analyze faults in the building management system. The controller detects a fault in the building management system by evaluating data of building management system using a system of rules. The controller determines a conditional probability for each of a plurality of possible fault causes given the detected fault. The controller determines the most likely fault cause by comparing the determined probabilities and electronically reports the most likely fault cause.

A utility control system governs provision of genuine on-demand lighting, as well other utilities as in heating, ventilation and air conditioning (“HVAC”) in territories of a building in accordance with occupant demand. In lighting control, the present invention enacts on-demand illumination anterior to the occupant entering a normally dimmed/unlighted territory; lighting is provided immediately anterior to occupant entry into an oncoming territory. As the occupant leaves each territory, lighting provision is suspended/terminated in that territory for energy conservation. Signals and commands received by the utility control system from a plurality of override switches, interactive sensors and occupancy sensors within each monitored territory, as well as the control units of an elevator control system (“ECS”), a Building Management System (“BMS”) and a client computer govern the utility control system for configuring automated lighting provision. The utility control system predicts an occupant traversal path and provides the occupant with the best-suited lighted environments in each territory of the occupant traversal path.
