Energy Auditing mdash Foundation of the Process
Energy Auditing Goals
Third party software establishes an industry standard process
Compliant tool to be the scorecard for the program
Use a base year prior to the energy program as a basis to determine savings
Adjust the base yearrsquos consumption for current conditions
Corrects for changing conditions
Engages Client Partnership and Point of Contact
Justin Moss ndash Point of Contact (Energy Management Section)
Establishes an ldquoadjusted baselinerdquo
Compare the energy in the performance year to the adjusted base line
Process determines the performance period savings
Report the performance period savings
Based on the consumption avoidance
Valued at the current cost of utilities

Energy Auditing Goals
Third party software establishes an industry standard process
Compliant tool to be the scorecard for the program
Use a base year prior to the energy program as a basis to determine savings
Adjust the base yearrsquos consumption for current conditions
Corrects for changing conditions
Engages Client Partnership and Point of Contact
Justin Moss ndash Point of Contact (Energy Management Section)
Establishes an ldquoadjusted baselinerdquo
Compare the energy in the performance year to the adjusted base line
Process determines the performance period savings
Report the performance period savings
Based on the consumption avoidance
Valued at the current cost of utilities

Energy Auditing mdash Foundation of the Process
Energy Auditing Goals
Third party software establishes an industry standard process
Compliant tool to be the scorecard for the program
Use a base year prior to the energy program as a basis to determine savings
Adjust the base yearrsquos consumption for current conditions
Corrects for changing conditions
Engages Client Partnership and Point of Contact
Justin Moss ndash Point of Contact (Energy Management Section)
Establishes an ldquoadjusted baselinerdquo
Compare the energy in the performance year to the adjusted base line
Process determines the performance period savings
Report the performance period savings
Based on the consumption avoidance
Valued at the current cost of utilities
