Building energy management system with energy analytics

A method of building management comprising:

• collecting, by one or more processing circuits, data samples of one or more variables of a building from building equipment and generate a resource consumption timeseries indicating resource consumption of the building at a plurality of points in time;
• performing, by the one or more processing circuits, one or more energy analytics using the resource consumption timeseries and generate an energy usage metric timeseries comprising a plurality of result samples indicating an energy usage metric for the building;
• generating, by the one or more processing circuits, a results timeseries by removing an effect of weather from the resource consumption timeseries, wherein removing the effect of weather from the resource consumption timeseries includes:
• generating a regression model that defines a relationship between the data samples of the resource consumption timeseries and one or more weather-related variables;
• determining values of the one or more weather-related variables during a time period associated with the resource consumption timeseries;
• applying values of the one or more weather-related variables as inputs to the regression model to estimate weather-normalized values of the data samples;
• and
• storing the weather-normalized values of the data samples as the energy usage metric timeseries;
• and
• operating, by the one or more processing circuits, using the energy usage metric timeseries, a piece of building equipment.

One or more storage devices configured to store instructions thereon, that, when executed by one or more processors, cause the one or more processors to:

• collect data samples of one or more variables of a building from building equipment and generate a resource consumption timeseries indicating resource consumption of the building at a plurality of points in time;
• perform one or more energy analytics using the resource consumption timeseries and generate an energy usage metric timeseries comprising a plurality of result samples indicating an energy usage metric for the building;
• generate a results timeseries by removing an effect of weather from the resource consumption timeseries, wherein removing the effect of weather from the resource consumption timeseries includes:
• generating a regression model that defines a relationship between the data samples of the resource consumption timeseries and one or more weather-related variables;
• determining values of the one or more weather-related variables during a time period associated with the resource consumption timeseries;
• applying values of the one or more weather-related variables as inputs to the regression model to estimate weather-normalized values of the data samples;
• and
• storing the weather-normalized values of the data samples as the energy usage metric timeseries;
• and
• operate, using the energy usage metric timeseries, a piece of building equipment.
