THERMODYNAMIC MODELING FOR ENCLOSURES
First Claim
1. A method for modeling internal environmental behavior of an enclosure for use by a control system of an HVAC system installed in the enclosure comprising:
- actively inducing a change in the internal environment of the enclosure;
measuring a response of the internal environment of the enclosure at least in part due to the induced change; and
updating with a processing system a model for the enclosure that describes behavior of the enclosure for use by the control system, the updating being based at least in part on the measurement of the response from the induced change.

Abstract
Systems and methods for modeling the behavior of an enclosure for use by a control system of an HVAC system are described. A model for the enclosure that describes the behavior of the enclosure for use by the control system is updated based on a weather forecast data. The weather forecast data can include predictions more than 24 hours in the future, and can include predictions such as temperature, humidity and/or dew point, solar output, precipitation. The model for the enclosure can also be updated based on additional information and data such as historical weather data such as temperature, humidity, wind, solar output and precipitation, occupancy data, such as predicted and/or detected occupancy data, calendar data, and data from the one or more weather condition sensors that sense current parameters such as temperature, humidity, wind, precipitation, and/or solar output. The model for the enclosure can be updated based also on an enclosure model stored in a database, and/or on enclosure information from a user. The model can be updated based on active testing of the enclosure which can be performed automatically or in response to user input. The testing can include heating and/or cooling the enclosure at times when the enclosure is not likely to be occupied.

- 16. A system for modeling internal environmental behavior of an enclosure for use by a control system of an HVAC system installed in the enclosure comprising a processing system adapted and programmed to actively induce a change in the internal environment of the enclosure primarily for purposes of updating a model for the enclosure that describes behavior of the enclosure for use by the control system, to measure a response of the internal environment of the enclosure at least in part due to the induced change and to update the model for the enclosure based at least in part on the measurement of the response from the induced change.

30. A method for modeling the internal environmental behavior of an enclosure for use by a control system of an HVAC system installed in the enclosure, the method comprising:
-
receiving weather forecast data predicting future weather conditions for a region including the location of the enclosure; updating a model for the enclosure that describes behavior of the enclosure for use by the control system, the updating being based at least in part on the weather forecast data; and controlling the HVAC system with the control system using the updated model for the enclosure. - View Dependent Claims (31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52)

- 53. A system for modeling internal environmental behavior of an enclosure for use by a control system of an HVAC system installed in the enclosure, the system comprising a processing system adapted and programmed to receive weather forecast data predicting future weather conditions for a region including the location of the enclosure, and to update a model for the enclosure that describes behavior of the enclosure for use by the control system, the updating being based at least in part on the weather forecast data.
- 76. A system for modeling internal environmental behavior of an enclosure for use by a control system of an HVAC system installed in the enclosure comprising a processing system adapted and programmed monitor environmental conditions exterior to the enclosure, and environmental conditions of the interior of the enclosure, and to update a model for the enclosure that describes thermodynamic behavior of the enclosure for use by the control system, based at least in part on the monitored interior and exterior conditions.
