CHP Screening ToolA CHP screening tool has been developed by ORNL’s Cooling, Heating and Power Technologies program. This tool will evaluate the installations of systems for facilities hot water, electrical loads, heating, cooling, chillers, boilers, water heaters, and the costs of power and natural gas and the simulated performance of generators.This data is typically analyzed on an hour-by-hour basis so energy cost savings can be calculated accurately for time-of-day rates. What is determined from a facility is building loads from general parameters provided by the user, combine thermal and electrical loads with operating parameters for generators and HVAC equipment to determine energy requirements for part load and off-design operation of gensets and chillers, and to determine estimated annual electric and natural gas costs using algorithms from a database of gas and electric utility rates. In order to use the CHP screening tool successfully, some familiarity with HVAC and power generating equipment is required, but the user does not need to have any background in using DOE2.
