Abstract

A system and method for monitoring a heating, ventilation, or air conditioning (HVAC) system of a building is provided. A monitoring server, located remotely from the building, is configured to receive power consumption data and control signal data from a monitoring device at the building and to receive energy pricing data from a customer device associated with the HVAC system or a database that stores energy pricing data. The monitoring server is configured to determine energy cost data for segments of a selected time period based on the power consumption data, the control signal data, and the energy pricing data. The monitoring server is also configured to communicate the energy cost data to the customer device for display on the customer device.

3 . The monitoring system of claim 1 , wherein the selected time period includes a plurality of days and wherein each of the plurality of segments of the selected time period is at least one of a day and a portion of a day.

4 . The monitoring system of claim 1 , wherein the energy cost data includes a cumulative total energy cost for each segment of the plurality of segments, the cumulative total energy cost for each segment corresponding to a total energy cost from a start of the selected time period through an end of the segment.

5 . The monitoring system of claim 1 , wherein the selected time period corresponds to a seasonal transition time period and wherein the energy cost data includes energy cost data for the HVAC system while operating in a heating mode and in a cooling mode during the seasonal transition time period.

6 . The monitoring system of claim 1 , wherein the power consumption data includes an instantaneous power consumption of the HVAC system and wherein the monitoring server determines a runtime of the HVAC system based on the control signal data, determines a power consumption of the HVAC system over time based on the instantaneous power consumption and the runtime of the HVAC system, and determines the energy cost data for the plurality of segments of the selected time period based on the power consumption of the HVAC system over time.

7 . A method for monitoring a heating, ventilation, or air conditioning (HVAC) system of a building, the method comprising:
