U.S. EPA CHP Energy and Emissions Savings Calculator
Want to calculate the emissions savings from installing a combined heat & power system versus use of a comparable separate heat and power system (e.g., grid power and a boiler system)? Now you can, thanks to the tool developed by U.S. EPA Combined Heat & Power Partnership. Click here to access the Emissions Savings Calculator:
"The Combined Heat and Power (CHP) Energy and Emissions Savings Calculator (CEESC) (XLSM) (1 pg, 6 MB) is a Microsoft Excel-based tool that calculates and compares the estimated fuel consumption and air pollutant emissions (CO2e, SO2 and NOX) of a CHP system and comparable separate heat and power system (SHP) (e.g., grid power and a boiler system). The calculator also presents the carbon emissions reductions from a CHP system in terms of the emissions associated with passenger vehicles and the generation of electricity used by the average U.S. home.
The calculator uses fuel-specific emissions factors developed by EPA, and grid emissions factors and region-specific transmission and distribution (T&D) loss data from the Emissions & Generation Resource Integrated Database (eGRID).
The calculator is designed for users with at least a moderate understanding of CHP technology and its terminology. To learn more about CHP technologies, please visit the Catalog of CHP Technologies."
