Abstract: A method and system is provided that includes a setpoint monitor in communication with a controller that operates equipment according to setpoint values, each setpoint value having an associated benchmark value. The setpoint monitor receives setpoint modifications based on communication with the controller, each setpoint modification corresponding to a modification of a setpoint value to a modified value different from the associated benchmark value. A terminal in communication with the setpoint monitor displays the setpoint modifications and receives input to revert a setpoint modification from the modified value back to the associated benchmark value. The setpoint monitor communicates with the controller to revert the setpoint value associated with the setpoint modification from the modified value back to the associated benchmark value.

Abstract: A method and system is provided that includes a controller that operates at least one piece of equipment according to setpoint values and a setpoint monitor in communication with the controller. The setpoint monitor receives setpoint modifications, each setpoint modification corresponding to a modification of one of the setpoint values. The setpoint monitor calculates an expected change in energy consumption of the at least one piece of equipment for each of the setpoint modifications and ranks the setpoint modifications based on the expected change in energy consumption. A first terminal is in communication with the setpoint monitor and displays the setpoint modifications in an order based on the ranking of the setpoint modifications. The first terminal receives input for each setpoint modification of the plurality of setpoint modifications indicating approval or rejection of the setpoint modification.

Abstract: A method and system is provided that includes receiving a current setpoint value from a controller that operates at least one piece of equipment according to the current setpoint value, the current setpoint value being set by a first user, comparing the current setpoint value with a benchmark setpoint value, and outputting the current setpoint value and the benchmark setpoint value on a terminal when the current setpoint value is different than the benchmark setpoint value. The method and system also includes receiving, with the terminal, input from a second user indicating one of approval of the current setpoint value or rejection of the current setpoint value, notifying the first user that the current setpoint value has been rejected when the input from the second user indicates rejection of the current setpoint value, and communicating, to the terminal, input from the first user indicating one of agreement or disagreement with the rejection of the current setpoint value.

Abstract: A refrigerant leak detection system is herein disclosed. The system can detect the existence of a slow leak based on the refrigerant level and the system data. They system uses data models, either stored or dynamically created, to calculate an expected refrigerant level. Based on the expected refrigerant level and the actual refrigerant level and statistical process control data, a leak can be identified.

Abstract: A method of displaying building system controller data includes receiving a user login associated with predefined user access privileges and receiving a building system controller selection, requesting a listing of building system controller applications and activities from a building system controller associated with the building system controller selection, and generating a display of available building system controller applications and allowable activities based on the user access privileges and based on the listing.

Abstract: A method comprises grouping a plurality of building system controllers into at least one control system group, the at least one control system group corresponding to at least one connected group of building system controllers. The method also comprises grouping the at least one control system group into at least one site group, the at least one site group corresponding to a physical location of the at least one control system group. The method also comprises selecting a group from the at least one site group and the at least one control system group, and performing an activity on each controller within the selected group.
