Abstract

Systems and methods for assessing and optimizing energy use and environmental impact can be designed to receive energy consumption and emission data from one or more energy consumption sources of a facility over a network. The data can be transformed into a database format that can be processed and analyzed. The data can be validated according to predefined validation rules. The data can be aggregated according to predefined time intervals and stored in memory. The data can be used to generate a report to a user, for example, via a user interface.
