BAS Router The an online, real-time, building oversight management tool that provides oversight, analysis, and reporting for a building’s mechanical plant (e.g., HVAC) and utility management. It works with existing BAS through noninterfering interfaces that enhance, without disrupting, the operation of the equipment, controls, or BAS. Using these “technology agnostic” interfaces, the system collects and formats data for delivery over the Internet, monitors for operations and equipment error states (alerts or alarms), provides real-time oversight access via the internet, and monitors overall systems performance. Data collection and validation is accomplished on 5-, 10-, or 15-min user-selected intervals across multiple systems with simultaneous error correction for interrupted or lost communications, data points out-ofrange, and data anti-aliasing. The system utilizes an industry-standard, SQL-based relational data base (RDB) that reliably main- hardware and software capable of collecting and analyzing a large volume of data without degrading the control performance, which is the primary objective of those systems. Since most computer control systems are limited in processing speeds, bandwidth, and storage capacity, attempting to use them to compile large amounts of real-time data, unrelated or unnecessary to the control strategy, can adversely affect critical functionality. Also, some data points may be important to optimizing energy savings but are completely useless for automatic control (e.g., electric power metering). And, finally, there are no industry standards for the proprietary measurement algorithms that these systems use2. It seems logical, then, to look for alternative metering/monitoring solutions that are not an integral part of the BAS.
