Patent attributes
A controller and/or a gateway acts as a feedback-based energy estimator for controlling initial and refined estimates of energy usage of one or more buildings controlled by the controller or gateway. An initial estimate of a building's energy needs for a specified time in the future (e.g., a month or a week ahead) are calculated, and then over time, in conjunction with an energy company, the initial estimate (and subsequent estimates) is revised based on the costs of the energy predicted or quoted by the energy company. The controller may examine jobs to be performed at the time as well as predictive information that may affect the building's energy needs (e.g., the predicted temperature for the time of the predicted energy needs). As expectations change (or as predicted factors such as temperature change), the energy company may be informed of the additional energy that will be needed (e.g., if the predicted temperature is increasing and cooling will be needed) or the excess energy that is expected (e.g., if the predicted temperature is decreasing and less cooling will be needed).
