A method for performing energy management for a building includes generating a stack of energy loads representative of a plurality of building energy loads. The energy loads are prioritized from highest priority energy loads to lowest priority energy loads. The prioritized energy loads are then compared to a building power threshold. The lowest priority energy loads are shed until a sum of remaining energy loads is equal to or less than the building power threshold. The remaining energy loads are serviced. The processes of prioritizing the energy loads, comparing the prioritized energy loads to a building power threshold, and shedding the lowest priority energy loads is repeated in response to changes in circumstances affecting the building.

Disclosed herein is an electric power management apparatus including: an electric power measurement block configured to measure an electric power consumption amount of an electric power consumer; and an electric power comparison block configured to make a comparison between an electric power consumption amount measured by the electric power measurement block and an electric power demand forecast amount indicative of a forecast amount of an electric power demand of the electric power consumer.
