“…Newer EMCS have ability to extensively monitor a building using digital controls. There is great potential to use EMCS trend logs to assess building performance, but the use of this data for diagnostics must be evaluated on a site-by-site basis due to differences in EMCS trending and archiving capabilities (Heinemeier, 1994). Typically, even the new EMCS do not have embedded automated diagnostics, and it is often time consuming to export data from the EMCS into another software program (i.e., spreadsheets) for analysis.…”

“…Finally, a substantial body of work is dedicated to facilities' and service providers' use of building automation systems, or energy management and control systems. However, it tends to focus on questions concerning the use of HVAC data for applications external to the EMCS, and on HVAC performance diagnostics and fault detection (Friedman and Piette 2001;Heinemeier 1994;Webster 2005).…”

Measured energy performance data are essential to national efforts to improve building efficiency, as evidenced in recent benchmarking mandates, and in a growing body of work that indicates the value of permanent monitoring and energy information feedback. This paper presents case studies of energy information systems (EIS) at four enterprises and university campuses, focusing on the attained energy savings, and successes and challenges in technology use and integration. EIS are broadly defined as performance monitoring software, data acquisition hardware, and communication systems to store, analyze, and display building energy information. Case investigations showed that the most common energy savings and instances of waste concerned scheduling errors, measurement and verification, and inefficient operations. Data quality is critical to effective EIS use, and is most challenging at the subsystem or component level, and with nonelectric energy sources. Sophisticated prediction algorithms may not be well understood but can be applied quite effectively, and sites with custom benchmark models or metrics are more likely to perform analyses external to the EIS. Finally, resources and staffing were identified as a universal challenge, indicating a need to identify additional models of EIS use that extend beyond exclusive in-house use, to analysis services.
