; and (2) provide an estimate of potential energy savings, cost savings, and carbon emissions reductions that may be realized through pumping system improvements. (b) Requirements (1) Ease of use The Secretary shall ensure that the tool made available under subsection (a) provides a user with projected energy savings, projected cost savings, and projected carbon emissions reductions through the input by the user of the following data relating to an existing pumping system: (A) Pump type. (B) Flow rating and actual flow. (C) Pressure rating and actual pressure. (D) Speed rating and actual speed. (2) Considerations The Secretary shall ensure that the tool made available under subsection (a)— (A) in assessing the energy efficiency of a pumping system, takes into consideration pumps, pipes, motors, drives, and controls associated with the pumping system
