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.

• Comprehensive, extensive site shutdowns are key to achieving savings targets –
Summer 2014 (June - August) produced $180,862 or 37% of our annual savings.
• Electricity is our largest commodity and therefore warrants the greatest effort. Although
water represents our current challenge.
*Does not include special savings (credits) received against electricity & natural gas bills of $57,830
