Abstract:
1. A method implemented at least in part by a computer, the method comprising: receiving hardware node power state information in the form of logs recorded by respective hardware nodes, wherein the hardware node power state information comprises at least one record indicating a hardware user identifier, a timestamp, and a power on indication for a hardware node; receiving user attendance information for a plurality of users, wherein the attendance information comprises at least one user attendance record indicating an attendance user identifier, a timestamp, and an in-or-out indication, wherein an arrival time and a departure time of a user for a particular day is indicated; via correlation, identifying the arrival time of the user and the departure time of the user for the particular day and that the hardware node was left powered on when the user was absent for a certain period of time, wherein the correlation comprises correlating the attendance user identifier with the hardware user identifier; responsive to determining that the hardware node power state information and the attendance information indicate that the hardware node has been left on by the absent user for over a threshold amount of time, initiating shutdown of the hardware node; and based on the hardware node power state information and the user attendance information, calculating an energy wastage metric for the user.
