An additional purpose of this research is to establish a database of energy tariffs, DER technology cost and performance characteristics, and building energy consumption for Japan. This work demonstrates a method for choosing and designing economically optimal DER systems. Additional benefit can be achieved by integrating these more » distributed technologies into distributed energy resource (DER) systems. Introduction of on-site generation, renewable energy such as solar and wind power and the effective utilization of exhaust heat is needed, to meet the growing energy demands of the residential and commercial sectors. Failure of large power systems can lead to serious emergencies.
The blackout was a warning to the rest of the world that the ability of conventional power systems to meet growing electricity demand is questionable.
and CANADA caused great economic losses and inconvenience to New York City and other affected areas. The August 2003 blackout of the northeastern U.S. The authors also discuss the technology adoption process and decisions involved in such innovations. An office building demonstration site was selected because of the technical reputation and interest of the chief engineer and on-site operator. The authors review the installation and early results from the use of the IMDS. The system does not provide control functions. Five unique features of the project are (1) sophisticated building operators and engineers as users, (2) permanent installation, (3) high-quality sensing, (4) high-frequency data archives, and (5) top-down design (i.e., whole building, system, and component data).

The IMDS includes about 50 points of whole-building and cooling plant data, plus a set of standard diagnostics plots to evaluate key performance metrics and curves. The system is designed to more » address common O and M problems and the needs of office building owners and property managers to address these problems. This paper discussed a multi-year, multi-institutional project to develop and demonstrate an Information Monitoring and Diagnostics System (IMDS). Today's EMCS are designed for control, with limited capabilities in sensing, archiving, data analysis, diagnostics, and data visualization. The opportunity for O and M savings is related to systemic problems associated with the lack of feedback available from current Energy Management and Control Systems (EMCS). Performance monitoring projects have shown whole-building energy savings of 20% or more through improved operation and maintenance practices. Large commercial buildings generally do not operate at economically achievable levels of energy efficiency.
