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!
