20:10:38:05.  Measured savings approaches. A measured savings approach shall be based on one or more of the following methods:

          (1)  The use of direct metering and monitoring to measure baseline energy use and post-installation energy use;

          (2)  The use of engineering methods that use standard formulas and assumptions to calculate the energy use of baseline and post-installation energy systems;

          (3)  The use of statistical analyses to estimate baseline energy use and post-installation energy use; or

          (4)  The use of computer models to predict the change in energy use after energy efficiency measures are implemented.
