System and method for using a network of thermostats as tool to verify peak demand reduction
First Claim
1. A system for verifying the occurrence of a change in operational status for an HVAC control system comprising:
- at least one HVAC control system that measures temperature at at least a first location conditioned by said HVAC system, and reporting said temperature measurements as well as the status of said HVAC control system;
one or more processors that receive measurements of outside temperatures from at least one remote source other than said HVAC control system at the first location, wherein said remote source is a weather database that provides outside temperatures based on the zip code of the first location, and wherein the one or more processors compare said temperature measurements from said first location and said outside temperatures received from said remote source, with expected temperature measurements of said first location wherein the expected temperature measurements are based at least in part upon past temperature measurements obtained by said HVAC control system, said temperature measurements from said HVAC control system, said outside temperature measurements from said remote source, and further based at least in part on predicted changes to temperatures when said HVAC system reduces output in response to a demand response request; and
at least one remote server that transmits changes in programming to said HVAC control system to reduce output based at least in part on an occurrence of a demand reduction request,wherein if the temperature associated with the first location is changing as predicted by the expected temperature measurements, the remote server determines that the HVAC control system is functioning according to the changes in programming and confirms that the location is complying with the demand reduction request based on comparing, after occurrence of said demand reduction request, temperature measurements obtained within said first location with said expected temperature measurements, andwherein if the temperature inside the first location is not changing as predicted by the expected temperature measurements, the remote server determines that the HVAC control system is not functioning according to the changes in programming and confirms that the location is not complying with the demand reduction request based on comparing, after occurrence of said demand reduction request, temperature measurement obtained within said first location with said expected temperature measurements.

Abstract
The invention comprises systems and methods for verifying the occurrence of a change in operational status for climate control systems. The climate control system measures temperature at least a first location conditioned by the climate control system. One or more processors also receive measurements of outside temperatures from at least one source other than the climate control system, and compares the temperature measurements from the first location with expected temperature measurements. The expected temperature measurements are based at least in part upon past temperature measurements obtained by the climate control system and the outside temperature measurements. A server transmits changes in programming to the climate control system based at least in part on the comparison of the temperature measurements with the expected temperature measurements.

8. A system for predicting the thermal performance of a structure as conditioned by an HVAC system, comprising:
-
at least one HVAC control system that measures temperature at at least one location conditioned by said HVAC system, and reports said temperature measurements as well as status of said HVAC control system; a database that stores said temperature measurements and said status; at least one remote server that transmits changes in programming to said HVAC control system based at least in part on a demand reduction request, one or more processors that compare said temperature measurements at said location with predictions of changes to temperatures when said HVAC system reduces output in response to the demand response request, wherein said predictions are based at least in part on outside weather data obtained from a remote source comprising a weather database, previous temperature measurements and previous status wherein said comparisons are used to determine whether said status of the HVAC system is consistent with said predictions, said previous temperature measurements, said previous status, and said outside weather data to confirm whether the HVAC system is functioning according to the changes in programming associated with the demand reduction request, or to confirm whether the HVAC control system is not functioning according to the changes in programming associated with the demand reduction request. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15, 16)

17. A system for verifying that the operating parameters of an HVAC system have been adjusted as requested in response to a control signal comprising:
-
at least one HVAC control system capable of measuring temperature at at least one location conditioned by said HVAC system, and reporting said temperature measurements as well as the status of said HVAC control system; means by which said temperature measurements and HVAC status may be stored in a database; means for transmitting a control signal comprising changes in programming to said HVAC control system based at least in part on a demand reduction request; means by which such temperature measurements and HVAC status may be compared with outside weather data obtained from a remote source and previous temperature measurements and HVAC status; and means for determining whether the reported temperature information and status of the HVAC system are consistent with predictions of changes to temperatures when said HVAC system reduces output in response to the demand response request, wherein said predictions are based at least in part on the outside weather data obtained from the remote source, previous temperature measurements and previous status, to confirm whether the HVAC system is functioning according to the changes in programming associated with the demand reduction request, or to confirm whether the HVAC control system is not functioning according to the changes in programming associated with the demand reduction request.
