PhaseIResults•After implementation is complete, Measurement & Verification (M&V) phase begins to prove success of the project
•In Phase I, Johnson Controls (JCI) guaranteed $1,913,955 in annual savings for the District
•If those savings were not achieved, JCI would write the District a check to make up for the shortfall
•Findings of M&V Report• Ph I savings exceeded guarantee by ~20% ($201,041)• PSE&G Rebate achieved $1.0M vs the expected $869,000
