COOLING, HEATING, AND POWER APPLICATION SCREENING TOOL


Over half of the energy of the fuel burned to produce electric power at conventional power plants is
rejected to the environment while only 30% to 35% is delivered to the end user as electricity. Large
district energy systems recover a significant portion of the waste heat and distribute it to nearby homes
and businesses for space heating, hot water, or sometimes space cooling. There are instances where the
energy and cost savings of power generation and heat recovery can be realized on a smaller scale through
cooling, heating, and power – integrated energy systems (CHP-IES) for individual buildings or small
campus settings. The U.S. Department of Energy undertook this project to develop an accurate, easy-touse
computational tool for estimating the economic viability of CHP-IES in the United States.
