Abstract: An energy meter is configured to determine component waveforms that form a measured waveform. The meter inputs the waveform into one or more entries of a data structure, each entry of the one or more entries of the data structure storing a weight value that is determined based at least in part on values of the data signatures representing the plurality of remote devices, each entry being connected to one or more other entries of the data structure. The meter, for each of the one or more entries, generates an output value by performing an arithmetic operation on the waveform stored at that entry, the arithmetic operation comprising a function of the weight value. The meter identifies, from among the data signatures, one or more particular data signatures that are represented in the waveform. The meter determines, based on the particular data signatures, an operational state of another device.

Abstract: A computer-implemented method includes, in one aspect, retrieving HVAC system information; converting the retrieved HVAC system information from one or more first data formats to a second data format; storing the converted HVAC system information; identifying first portions of the stored HVAC system information that pertain to a particular component; and generating one or more associations among the identified, first portions of the stored HVAC system information; receiving a request for HVAC system information that is used by a performance analysis algorithm; determining a type of component of the HVAC system that is related to the requested HVAC system information; and identifying one or more items of the stored HVAC system information that is of the requested HVAC system information; and transmitting the identified one or more items of the stored HVAC system information for use in execution of the performance analysis algorithm.
