The development of the Carbon Heat Energy Analysis Plant Evaluation Tool (CHEApet) by the Water Environment Research Federation (WERF) was in response to the identified need for a predictive modeling tool that unifies prior WERF research information regarding quantifying and managing energy consumption. CHEApet was created under OWSO4R07C of WERF's Optimization Challenge to model performance and energy consumption of waste water treatment plants (WWTPs). Energy consumption, along with treatment process emissions, contributes to a facility's carbon footprint. CHEApet can be used to create a baseline scenario, or inventory, of a utility's carbon footprint for informational purposes as well as to compare with hypothetical treatment plants. This kind of comparison allows the user to identify facilities in the utility for energy optimization and the potential for biogas recovery which can save in costs and improve the footprint of the facility.

Keywords: energy optimization; greenhouse gas emissions; process modeling
