The last few years witnessed a significant rise in the availability of analytical software that offer functionalities such as advanced automated fault detection and diagnosis systems (AFDDS). These software programs complement the more traditional Building Energy Management Systems (BEMS). This, combined with the expanded capabilities of BEMS, has made it increasingly difficult for utilities to quantify the benefits of these tools.

The project was composed of two distinct tasks. The first task addressed the inventory of energy management systems and automated fault detection/diagnostic systems, while the second task dealt with estimates of savings resulting from different levels of automation and fault detection/diagnosis. For completeness, the report also covers Energy Information Systems (EIS), which are systems that help operators collect and visualize data generated by the BEMS.
