Define Criteria for Measurement

• Energy and water performance goals

• Levels of measurementLevels of measurement

• How information will be used to

manage performancemanage performance.

• How are costs assigned or allocated?

D fi illi t i l t d t• Define willingness to manipulate data

to get to more detailed tracking.

Design to Optimize Performance

• Building Energy Modeling

• Metering, Submetering

• Identify BAS Tracking Points• Identify BAS Tracking Points

Optimize System Performance

• Commission the building systems

Develop building systems• Develop building systems O+M plans

• Develop measurement & verification plan

Measure Actual Performance

• Track utility usage • Compare actual energy use

modeled energy use– Adjust and recalibrate– Investigate discrepanciesInvestigate discrepancies

The more measurement points, the easier to identify sources of problems

modeled energy use     vs actual energy use

Manage Ongoing Performance

• Continue to track utility usage • Look for patternsLook for patterns• Investigate discrepancies• Manage human behaviorgIt’s a journey . . . Not a destination!
