Abstract: A system for securely communicating information in a building management system (BMS) includes a plurality of HVAC devices communicably coupled via a network each HVAC device storing a copy of an HVAC data chain that includes a plurality of blocks linked sequentially. The plurality of HVAC devices includes a first HVAC device including a processing circuit configured to generate a first block comprising device data and send the block to at least a portion of the plurality of HVAC devices. The processing circuit is configured to receive a second block from one of the plurality of HVAC devices and solve the second block. The processing circuit is further configured to add the solved block to the HVAC data chain of the first HVAC device as the newest block and send the solved block to each of the plurality of HVAC devices.

Abstract: A building management system (BMS) includes building equipment configured to provide raw data samples of one or more data points in the BMS. The BMS further includes a data collector configured to collect raw data samples from the building equipment and generate one or more raw data timeseries comprising a plurality of the raw data samples. The BMS also includes a timeseries processing engine. The timeseries processing engine is configured to identify one or more timeseries processing workflows that apply to the raw data timeseries, each of the workflows comprising a predefined sequence of timeseries processing operation. The timeseries processing engine is further configured to process the raw data timeseries using the identified timeseries processing workflows to generate one or more derived data timeseries. The BMS further includes a timeseries storage interface configured to store the raw data timeseries and the derived data timeseries in a timeseries database.

Abstract: A building management system (BMS) includes building equipment configured to provide raw data samples of data points in the BMS, a data collector configured to generate raw data timeseries including raw data samples from the building equipment, and a timeseries processing engine. The timeseries processing engine is configured to identify an initial timeseries processing workflow that applies to the raw data timeseries, identify other data timeseries required as inputs to the initial timeseries processing workflow, and generate an enriched timeseries processing workflow that includes the initial timeseries processing workflow, the raw data timeseries, and the other data timeseries. The timeseries processing engine is configured to execute the enriched timeseries processing workflow to generate a derived data timeseries. The BMS further includes a timeseries storage interface configured to store the raw data timeseries and the derived data timeseries in a timeseries database.
