The Report

Based on information supplied by the client and data collected during the assessment, the IAC-SFSU team will prepare a professional-grade report including an energy balance of the facility, indicating the energy consumption of each operation, as well as in-depth analyses of identified conservation opportunities for energy, water use and waste generation. Such analyses include evaluation of cost savings, implementation costs and simple payback periods. Self-generation opportunities are also considered when appropriate. The report is a tool which allows the client to evaluate the impact of each opportunity on productivity improvement.

Approximately two months after the assessment date, the report will be submitted to the client. A fully anonymous version of the report will be submitted to the Center for Advanced Energy Systems at Rutgers University, the organization appointed by the DOE to conduct quality control for the IAC program. Anonymous statistical data of the report will be uploaded into the DOE IAC database which is used for energy related research nationwide.
