• We monitor & analyze district utility data …

- Through the use of an industry standard software program called EnergyCAP- Energy CAP meets a standard written by the U.S. Department of Energy called the

International Performance Measurement & Verification Protocol (U.S. DOE Document

#DOE/GO-102002-1554)

• In order to account for changes in energy usage from year-to-year, the standard

prescribes certain adjustments should be made for …

Changes in weather

Changes in building sq. ft., inc’l the addition/removal of portable buildings

Adding/removing mechanical systems & other energy consuming technology

Differences in base year and current year monthly billing cycles

• Savings is the value of the energy we did not use. It is the difference between the

expected energy use (at current rates) and the actual energy cost.
