Leadership and Focus (Guiding the Process towards the Lesson’s Objective)
Measurement and Verification (Checking for Understanding and Post-testing)
How implemented …





By auditing sites to identify energy-saving opportunities
By informing staff at all levels of energy-saving procedures
By helping staff to understand and move in a direction towards conservation
By maintaining a data base of bills/usage and auditing to ensure energy-saving
habits are followed daily and are commonplace

We use an industry-standard software program, Energy CAP, to measure
and verify SVUSD’s cost avoidance . . .
Energy CAP meets International M&V Standards …

The U.S. Department of Energy headed an effort to develop a written standard that became
the International Performance Measurement & Verification Protocol (U.S. DOE Document
#DOE/GO-102002-1554)
To account for changes in energy usage, this standard prescribes that certain usage
adjustments be made for …




Changes in weather
Added/removed mechanical systems and other energy consuming technology
Changes in building square footage, including the addition or removal of portables
Differences in the length of monthly billing cycles between the base period and current
reporting period
Cost Avoidance is determined by applying the current energy unit cost to the difference
between the adjusted, estimated usage and actual usage for each meter
* The practice of measuring energy savings and verifying cost avoidance.

Per the EPA, the following levels of Greenhouse Gas Emissions are produced by
our energy suppliers:
0.713 pounds of carbon dioxide per kilowatt-hour (kWh) of Electricity
11.7 pounds of carbon dioxide per therm of Natural Gas
During the past 14 months, SVUSD has saved …
6,057,703 kWh of Electricity
32,339 therms of Natural Gas
These savings are equal to …
2,130 Metric Tons of carbon dioxide emissions being prevented, or
382 Automobiles being removed from the highways annually, or
54,491 Tree Seedlings planted and grown for 10-years.

Our goals for the next 6 months are to:





Strive to maintain overall savings at or above 20%
Increase water conservation efforts
Focus on improving daily shutdowns, district wide
Submit high performing schools for Energy Star recognition
Increase awareness and visibility of the Energy Program in the community
The success of our Energy Conservation Program is due to the participation of
our custodians, faculty, kitchen staff and administration. A special thanks to…
