Claim 10:
11. An apparatus to dynamically assess energy usage of a pump installed in a facility, the apparatus comprising:
an energy management system including at least one computer processor, the energy management system configured to obtain a minimum energy consumption of the pump and the facility that includes installed building systems, subsystems, and components, wherein obtaining the minimum energy consumption comprises:
obtaining, with the at least one computer processor, a theoretical minimum energy consumption of the pump based at least in part on theoretical efficiency limits of the pump;
obtaining, with the at least one computer processor, an achievable energy consumption of the pump based at least in part on specifications associated with high energy-efficiency equivalents of the pump; and
obtaining, with the at least one computer processor, a designed minimum energy consumption of the pump based at least in part on specifications associated with the pump;

a plurality of measurement devices configured to measure, at least once a minute, an actual energy consumption of one or more of the pump, installed building systems, subsystems, and components;
the energy management system including a first analog input/output module and a second analog input/output module, the energy management system further configured to receive the measurement of the actual energy consumption of the one or more of the pump, installed building systems, subsystems and components, wherein receiving the measurement of the actual energy consumption comprises:
receiving, with the first analog input/output module, first data associated with the one or more of the pump, installed building systems, subsystems and components, the first data having a first protocol;
receiving, with the second analog input/output module, second data associated with the one or more of the pump, installed building systems, subsystems and components, the second data having a second protocol different from the first protocol;
sampling, at least once a minute, the first and second data to provide first and second digital data; and
transmitting at least one of the first and second digital data over a network having a protocol different from the first and second protocols; and

the energy management system further configured to compare, with the at least one computer processor, the minimum energy consumption to the measurement of the actual energy consumption to calculate an energy performance assessment that is based on theoretical, achievable, and designed energy efficiencies of the pump, wherein comparing the minimum energy consumption to the measurement of the actual energy consumption comprises:
comparing, at least once a minute, the theoretical minimum energy consumption of the pump to the measurement of the actual energy consumption to determine the theoretical energy efficiency;
comparing, at least once a minute, the achievable minimum energy consumption of the pump to the measurement of the actual energy consumption to determine the achievable energy efficiency; and
comparing, at least once a minute, the designed minimum energy consumption of the pump to the measurement of the actual energy consumption to determine the designed energy efficiency.
