Trends in Energy Management Technologies - Part 5: Effectiveness of Energy Management Systems: What the Experts Say and Case Studies Reveal

Abstract

At the Berkeley Structural Genomics Center (BSGC), our goal is to obtain a nearcomplete structural complement of proteins in the minimal organisms Mycoplasma genitalium and M. pneumoniae, two closely related pathogens. Current targets for structure determination have been selected in six major stages, starting with those predicted to be most tractable to high throughput study and likely to yield new structural information. We report on the process used to select these proteins, as well as our target deselection procedure. Target M. genitalium) during the same period. As the number of structures contributed by the BSGC during that period is less than 1% of the total worldwide output, the benefits of a focused target selection strategy are apparent. If the structures of all current targets were solved, the percentage of M. pneumoniae proteins for which folds could be reliably assigned would increase from approximately 57% (391 of 687) at present to around 80% (550 of 687), and the percentage of the proteome that could be accurately modeled would increase from around 37% (254 of 687) to about 64% (438 of 687). In M. genitalium, the percentage of the proteome that could be structurally annotated based on structures of our remaining targets would rise from 72% (348 of 486) to around 76% (371 of 486), with the percentage of accurately modeled proteins would rise from 50% (243 of 486) to 58% (283 of 486).

Building energy information systems: user case studies

“…Note that prior research in the use of building management systems at government buildings identified similar challenges in proactivity, resources, and energy management (Webster 2005). Overall, the energy manager reports a high level of satisfaction with WebCTRL emphasizing that UC Merced trends extremely large volumes of data and that intensive monitoring needs to be undertaken deliberately, with close attention to a spectrum of issues including wiring, system programming, network architecture, and hardware selection.…”

“…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).…”

“…Case studies from the building energy analysis community are more objective in their assessments, and more varied in the content and level of detail. Integration and installation, and the use of EMCS data are more frequently asked about (Capehart and Capehart 2005;Capehart et al 2007;Webster 2005) than the relationship between software features, actions taken, and resulting energy savings . When features actions and savings are addressed in the literature, the overall topic is usually not whole-building EIS diagnostics, but rather equipment and system level operational diagnostics.…”

Building management system for sustainable built environment in Sri Lanka

“…Similarly, a BMS makes operation and management easy in a complex mechanical and electrical services environment (Anon, 2005). However, design, installation, commission, and operation, building management structure and the interactions between all of these must be considered in utilising a BMS (Webster, 2005). Piper ( 2004) identified two elements of successful BMS implementation.…”
