Systems and methods for control optimization of building subsystems are disclosed. In some embodiments, a system comprises at least one processor; and memory storing instructions executable by the at least one processor, the instructions when executed cause the system to: obtain building load information, the building load information related to one or more power consuming subsystems of the building; determine a future building load based on the building load information; and adjust one or more setpoint tolerances for the one or more subsystems based on the determined future building load.

Systems and methods for control optimization of building subsytems

A method includes, accessing a first fill level timeseries generated by a first refrigeration system; detecting a first reduction in refrigerant fill level in the first refrigeration system; correlating the first reduction in refrigerant fill level with a first refrigerant; accessing a first discharge pressure timeseries; deriving a first correlation between a first leak-prediction characteristic of the first discharge pressure timeseries and the first refrigerant leak; accessing a discharge pressure timeseries generated by a second refrigeration system; in response to detecting presence of the first leak-prediction characteristic in the third discharge pressure timeseries, predicting a second refrigerant leak in the second refrigeration system; generating a notification identifying the second refrigerant leak in the second refrigeration system; and serving the electronic notification to an operator associated with the second refrigeration system.
