Abstract: A method assesses an energy impacting event at a facility using an energy management system. One or more energy consuming endpoints of the facility are sub-metered and data from the sub-metered endpoints is transmitted to the energy management system. A project is created within the EMS by entering project definition attributes including at least a site name, a project name, and a start date. Data from one or more sub-metered channels and a project indicator is displayed. The displayed project indicator is located at a point corresponding to its project start time. A further method tracks the progress of energy saving project at a facility using an energy management system. The project definition attributes further include one or more sub-metered channels, baseline usage data, and an energy related goal. An energy impact value is calculated by subtracting the actual sub-metered usage data from the baseline data and a determination is made whether the energy impact value meets or exceeds the energy goal. The baseline usage data, the energy goal data, the actual sub-metered data, and an indication of whether the energy goal was met are displayed. A further method tracks the financial progress of energy saving project at a facility using an energy management system. The project definition attributes further include one or more capital investment outflow values, a discount rate, and an energy cost rate. Net actual project cash flows and the net project goal cash flows are both plotted against a time scale and periodically displayed. An estimated net present value and net present value are periodically calculated and displayed.
