Unique systems, methods, techniques and apparatuses of building power management are disclosed herein. One exemplary embodiment is a system comprising a load management controller and a power circuit interrupter. The load management controller is configured to repeatedly perform a first test wherein a time rate of change of temperature of building regions is determined, repeatedly perform a second test wherein a lighting controller is operated to rank a plurality of lighting loads according to ambient light of building regions associated with the plurality of lighting loads, assign the plurality of HVACR loads and lighting loads to a plurality of load shed groups, and reduce power consumption by the plurality of HVACR loads and the plurality of lighting loads in order of the ranked load shed groups effective to minimize occupant perceptibility of the power consumption reduction while implementing the operator specified priority criteria.
