Identifying Small Building Types and Requirements for Microprocessor Energy Management Systems. Final Report

摘要

The purpose of this study was to identify the types of federally-owned buildings which are classified as small, i.e., under 200,080 ft. exp 2 , the energy use systems most commonly found in those buildings, the energy saving potential of applying microprocessor energy management systems (EMS's), the appropriate monitor and control points of the EMS's, and the projected impact of installing similar systems in buildings in the private sector. Microprocessor EMS's are advanced control systems designed to improve the operation of energy use systems and, thus, to reduce energy consumption. Typical ones include control equipment such as timeclocks, outside air controllers, temperature analyzers, and on/off controllers. The analysis of small federally-owned buildings showed that housing, service, storage, and office buildings accounted for over 80% of the small buildings. An analysis was made of the types of energy use systems commonly used in the selected building types to determine where and to what extent energy use could be reduced with an energy management system. The appropriate monitor and control points were determined and an estimate of the potential energy savings was made for both federally-owned buildings and their private sector counterparts. It was estimated that potential energy savings of 2 to 30% could result from using EMS's in small federally owned buildings. These results can be used to estimate the potential savings in small buildings in the private sector. (ERA citation 04:046889)
