CHP Emissions Calculator
- CHP Emissions Calculator (XLS, 1.5 MB, About XLS
) Last updated September 3, 2008
The Combined Heat and Power (CHP) Emissions Calculator (XLS, 1.5 MB, About XLS) compares the anticipated carbon dioxide (CO2), sulfur dioxide (SO2), and nitrogen oxide (NOx) emissions from a CHP system to those of a separate heat and power system. The calculator also presents estimated emissions reductions as metric tons of carbon equivalent, acres of fir or pine trees and emissions from passenger vehicles, as shown below.
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.
The estimate of environmental benefits of CHP generated by the calculator are appropriate for educational and outreach purposes only.
CHP Emissions Calculator
Basic Directions
The calculator provides concise instructions and default values for each of the inputs within the tool. To view input notes, move the mouse cursor over any cell with a red triangle in its upper right-hand corner.
The tool will work with a minimum of three pieces of information about the CHP system being evaluated:
- Technology type (also known as the CHP prime movers)
- Size/capacity
- Fuel type
For users who are interested in more accurate emissions estimates, the calculator allows users to specify up to 26 additional CHP system characteristics.
For detailed information and instructions, please refer to the user instructions tab included in the calculator. If you need help when using the tool, please contact EPA Technical Support Contractor Bob Sidner (bob.sidner@erg.com), (703) 633-1701.
