Integrated Energy Systems (IES) for Buildings: A Market Assessment

Date Published: August 1, 2002     Document Type: Market Research Report, Report

Integrated Energy Systems (IES) combine on-site power or distributed generation technologies with thermally activated technologies to provide cooling, heating, humidity control, energy storage and/or other process functions using thermal energy normally wasted in the production of electricity/power. This study examines the potential for IES in buildings when the system perspective is taken, and the IES is employed as a dynamic system. The study estimates the market potential for IES by analyzing IES performance on an hour-by-hour basis, examining the full range of building types, their loads and timing, and assessing how these loads can be technically and economically met by IES. The study summarizes the current state-of-the-art in cooling technologies that can be employed in the buildings sector within an IES, including absorption, desiccant, and engine-driven units. It quantifies the buildings market for IES and models the performance of these units so that the full range of economic benefits can be incorporated. The report identifies key market drivers and barriers and explores potential areas for technology research and development that could improve the prospects for IES in buildings. In addition, the study identifies where substantial barriers exist and the potential market effects of overcoming these obstacles.
