1. A method to dynamically assess energy efficiency of a facility, the method comprising:

  • obtaining, with computer hardware including at least one computer processor and non-transitory computer-readable storage, a minimum energy consumption of the facility that includes installed building systems, subsystems, and components, wherein obtaining the minimum energy consumption comprises;

    obtaining a theoretical minimum energy consumption of the facility based at least in part on theoretical efficiency limits of the installed building systems, subsystems, and components;

    obtaining an achievable energy consumption of the facility based at least in part on specifications associated with high energy-efficiency equivalents of the installed building systems, subsystems, and components; and

    obtaining a designed minimum energy consumption of the facility based at least in part on specifications associated with the installed building systems, subsystems, and components;

    receiving, at least once a minute, a measurement of an actual energy consumption of the installed building systems, subsystems, and components wherein receiving the measurement of the actual energy consumption comprises;

    receiving, with a first analog input/output module, first energy data associated with a first electrical circuit of the installed building systems, subsystems and components, the first energy data having a first protocol;

    receiving, with a second analog input/output module, second energy data associated with a second electrical circuit of the installed building systems, subsystems and components, the second energy data having a second protocol different from the first protocol;

    sampling, at least once a minute, the first and second energy data to provide first and second digital enemy data; and

    transmitting at least one of the first and second digital energy data over a network having a third protocol; and

    comparing, with the computer hardware, 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 enemy efficiencies of the facility, 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 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 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 to the measurement of the actual energy consumption to determine the designed energy efficiency.
