Abstract: A computer-implemented system and method are disclosed for performing engineering review of energy consumption by one or more equipment. One or more computers are connected to a specifications database. The computers are configured to receive end-user configurations corresponding to first equipment; retrieve one or more second equipment, as well as second equipment specifications from the specifications database; calculate an invoicing statement for the second equipment; and provide an engineering review report of the energy savings realized by implementing the second equipment. The first equipment may be an existing equipment, while the second equipment is one or more energy-efficient replacement alternatives to the first equipment. Each step is performed in real-time, using automated software modules and sub-modules.
