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.

Integrated information framework for automated performance analysis of heating, ventilation, and air conditioning (HVAC) systems

Methods and software for automatedly answering dynamic queries requiring fusing of data from various ones of multiple available heterogeneous data sources. The data sources are characterized and interrelated using a suitable ontology. In one implementation, each dynamic query is analyzed to determine the data items required to answer that query, along with their levels of detail. The data items and levels of detail are used to determine which ones of the multiple data sources are needed to answer the query. The data items, levels of detail, and the ontology of the data sources are then used to automatedly develop a data-fusing plan for fusing data from the needed data sources in a manner that answers the query. The data-fusing plan is executed, and the query is answered.
