Description
Discusses a prototype knowledge-based system (KBS) designed to work with hourly data from an EMS. The system incorporates about 130 rules, relies on a commercially available expert-system shell, in its test phase, has run in conjunction with a data acquisition system in a commercial building. The system compares measurements with expected performance of such components as chillers, the variable-air-volume (VAV ventilation system, and heat exchangers. The purpose of the system is not to serve as a consultant to which a user with a problem comes for help but, instead, to provide expert on-line review of available information about HVAC performance. This paper outlines the design of the system, identifies the required measurements and specifications, and note the kinds of problems the system can detect. We also point out which problems could have been detected with daily monitoring of whole-building or submetered energy consumption and which could have been eliminated with better control algorithms.
KEYWORDS: energy management, controls, expert systems, comparing, measuring, chillers, variable volume air conditioning, heat exchangers, specifications, building services, detecting, monitoring, buildings, energy consumption, energy, performance.
