This document specifies requirements for a computerized automated diagnostic tool for the detection of faults in certain heating, ventilation, and air-conditioning (HVAC) system components. The automated diagnostic tool is being developed for Architectural Energy Corporation (AEC) by Battelle as part of a program sponsored by the California Energy Commission (CEC). Supplemental cost-share funds are provided by U.S. Department of Energy through the Pacific Northwest National Laboratory (PNNL). This Requirements Specification (RS) specifies the essential capabilities required of the automated diagnostic tool. The purpose of this document is to clarify for AEC, the California Energy Commission (CEC), the Office of Buildings Programs, Office of Energy Efficiency and Renewable Energy (EERN) of the U.S. Department of Energy, and the project team the results that must be achieved by the automated diagnostic tool. The automated diagnostic tool detects and identifies faults in chillers and cooling tower subsystems of HVAC units using sensed data acquired from the unit, unit specifications, unit installation and configuration data, and unit operation data (such as schedules). The tool is a software product that will be utilized primarily by building operators and facilities managers and only secondarily by HVAC service technicians, energy service providers, and operation supervisors.
