Trend analysis for commissioning

This article shows how using automated analysis on trend data from energy management and control systems (EMCS) can serve as a powerful tool for troubleshooting control systems. Many EMCS systems are never commissioned fully or correctly, leaving the building operator with a less than fully functioning system.1,2 The main obstacle in providing better building performance has been the com-plexity of modern EMCS systems. They have evolved rapidly, requiring extensive training of designers, installers and users. Where this training is not present, many of the potential advantages of EMCS end up not being realized.
