Abstract: Systems and methods for evaluating a fault condition in a building include determining a change to energy use model parameters attributable to the fault condition. The change to the energy use model parameters are used to calculate a corresponding change to the building's energy consumption.

Abstract: Systems and methods for limiting power consumption by a heating, ventilation, and air conditioning (HVAC) subsystem of a building are shown and described. A mathematical linear operator is found that transforms the unused or deferred cooling power usage of the HVAC system based on pre-determined temperature settings to a target cooling power usage. The mathematical operator is applied to the temperature settings to create a temperature setpoint trajectory expected to provide the target cooling power usage.

Abstract: A system for generating an energy use model of a building includes a processing circuit operable to receive building data indicative of a first type of building variable and to receive additional building data correlated to an energy use of the building. The processing circuit is also operable to determine a portion of the building variable that is uncorrelated with the additional building data. The processing circuit is further operable to use the additional building data and the uncorrelated portion of the building variable to generate the energy use model of the building.

Abstract: Systems and methods for using an energy use model of a building for benchmarking is shown and described. An exemplary method includes receiving building data indicative of one or more characteristics of the building. The method further includes generating an energy use model for the building based on the building data and using the energy use model to generate statistics for the building. The method also includes identifying one or more other buildings having the same classification as the building. The method yet further includes comparing the generated statistics for the building to statistics for the identified one or more other buildings and providing an indication of the comparison.

The processing circuit is further configured to apply a regression analysis to the selected set of variables to generate a baseline model for predicting energy usage in the building.

Abstract: A method of maintaining a temperature of a surface in a building space to be above a dew point of the building space includes calculating a dew point based on a temperature measurement and a relative humidity measurement. The method further includes estimating a safety margin associated with the dew point calculation, determining a minimum temperature of the surface, wherein the minimum temperature is a function of the dew point and the safety margin, and commanding a first component of a building automation system to adjust a current temperature of the surface to be greater than the minimum temperature.

Abstract: A computerized method of determining the end of a measurement and verification period of a building management system is provided. The method includes calculating, for a plurality of periods, a target amount of energy savings resulting from energy conservation measures in a building. The method further includes calculating, for a plurality of periods, a least amount of energy savings resulting from energy conservation measures in a building. The method further includes comparing the target amount to the least amount. The method further includes ending the measurement and verification period, before the end of a maximum measurement and verification period, when the least amount is greater than the target amount. The method further includes outputting an indication that the measurement and verification period has ended to at least one of a memory device, a user device, or another device on the building management system.

Abstract: A computer system for use with a building management system for a building includes a processing circuit configured to determine a building's baseline energy usage model. The processing circuit may be configured to determine one or more automatically selected variables for use in the baseline energy usage model for predicting energy use in a building. The processing circuit may be further configured to cause the display of the one or more automatically selected variables on a user interface device. The processing circuit may be configured to receive, from the user interface, a selection of one or more variables which differ from the one or more automatically selected variables. The processing circuit may be further configured to use the received selection to generate a new baseline energy usage model.
