8. A computer program product for generating an operational rule associated with a building management system, the computer program product comprising: a non-transitory computer readable storage medium having program code embodied therewith, the program code executable by a computer to implement: identifying a first pattern associated with a series of operational observations corresponding to a property of the building management system, and identifying a second pattern associated with the series of operational observations; correlating a first contextual attribute with the first pattern; correlating a second contextual attribute with the second pattern, wherein the first pattern is based on a first resolution and the second pattern is based on a second resolution; and deriving the operational rule at least in part based on the first pattern and the first contextual attribute, and the second pattern and the second contextual attribute.
