Abstract:
1. A method of controlling energy usage in a building comprising: providing a main power source and a backup power source; partitioning electrical circuits into a main circuit groups and at least one sub-circuit groups; configuring a controllable transfer switch in a building to communicate with a utility network external to the building and an automation controller proximate the building and provide power from the main power source to the main circuit groups and the at least one sub-circuit groups in a first configuration and power from the backup power source to the at least one sub-circuit groups, but not the main circuit group in a second configuration; and, signaling the controllable transfer switch to switch from the first configuration to the second configuration to limit power consumption to the at least one sub-circuit groups; and, confirming a utility event notice received from the utility network with the automation controller before the controllable transfer switch switches configurations.
