1. A non-intrusive monitor of a space for occupants, comprising: a sensor module for monitoring a space, the sensor module is a non-intrusive sensor module for monitoring an occupancy of the space; and a processor connected to the sensor module; and wherein: the sensor module provides signals representative of occupancy of the space to the processor; the processor obtains utility information from a utility company over the internet, the utility information is related to energy usage of an area including the space and includes at least one indication of a power system disturbance of power to the space; the processor analyzes the signals representative of occupancy sensed at the space and the utility information, the analysis of the signals representative of occupancy sensed at the spaced and the utility information includes analysis of how the signals representative of occupancy sensed at the space responded to the power system disturbance of power to the space; the processor creates a model of a predicted energy usage of the space based on the analysis of how the signals representative of occupancy sensed at the space responded to the power system disturbance of power to the space.
