MampV Procedure



Executing the MampV Planbull Modeler

ndash Create model

ndash Adjust post-install model to sub-metered data

ndash Calibrate post-install model to utility amp weather data

ndash Create modify baseline models

bull Owner Facility Manager ndash Ensure metering specified and installed

ndash Assist with data collectionbull MampV Agent

ndash Design MampV approach

ndash Define baseline

ndash One-year MampV period ndash Set up trends and make measurements

ndash Perform energy savings calculations

bull Cx Agent

ndash Perform operational verification



Notable Challengesbull Create custom weather files

bull Align sub-metered data ndash Universal Translator httputonlineorgcms

bull pp y ng a us men s o ase ne mo ebull Ensure value to owner

ndash Useful Sub-metering

ndash Operational verification

ndash Establish expected performance

ndash Not academic exercise



Calibrate the model

bull Revise modeling assumptions

ndash Update weather data

ndash Compare with measurements

ndash Correct Wizard defaults other adjustments
