Air Force Approach: Measurement and Verification (M&V) Standardization

1. Air Force Approach:Measurement and Verification (M&V) Standardization K. Quinn Hart, PE

2. M&V Standardization • Provides the essence of what the Government expects the ESCO to provide in an M&V plan • Develops 18 standardized M&V plans

3. M&V Standardization • First ECP to Standardize • Heat Plant Decentralization • Most difficult • More potential for savings • Most time consuming to develop • Contains many elements • Sets benchmark for other ECP M&V prototypes

4. M&V Standardization • M&V Plan Elements • Establish pre ECP energy baseline • Establish ECP utility costs • Establish ECP performance criteria • Predict post ECP energy usage • Establish Acceptance criteria • Establish practical measurement criteria • Validate energy savings annually

5. M&V Standardization • Establish Pre ECP Energy Baseline • Facilities Served with ECP • Weather Normalized Regression • Pre-ECP Energy Usage • Pre-ECP O&M Costs • Establishment of Utility Costs

6. Pre ECP Facilities Conditions

7. M&V Standardization • Establish post ECP utility costs • Use current utility rates. • Exceptions • Current rates are momentary peaks (slumps) • Signed contract in hand for change to utility rates • Establish ECP performance criteria • Post ECP Required System Description • Post ECP Performance Requirements

8. Post ECP Required System Description

10. M&V Standardization • Predict Post ECP Energy Usage • Predicted Energy Usage • ESCO provides the formula and calculations required to support estimated post ECP energy usage • Predicted O&M Costs • ESCO provides the summary of O&M costs for the ECP • ESCO provides supporting O&M documentation in Appendix • ESCO accounts for new equipment O&M over the life of the contract

11. M&V Standardization • Establish Acceptance Criteria • Systems Performance Tests • Verify ECP performance requirements • Test Results Summary • Provide detailed performance testing procedures sufficient to prove the system will operate and perform to meet the conditions required • Project Acceptance • Compare test results with established performance criteria • Include information in table clearly demonstrating the target data and the actual achieved quantities

12. Project Acceptance Boiler Test Results

13. M&V Standardization • Establish practical measurement criteria • First year requirements • Validate performance for all boilers • Measure efficiency for boilers • Establish BTU weighted efficiency • Use predetermined BTU weighted efficiency calculations • Determine payment adjustment (if any) • Use predetermined adjustment calculations • Year two until end of Contract • Measure efficiency of a selected sample of boilers • Calculate the BTU weighted efficiency • Compare to first year baseline BTU weighted efficiency • Determine payment adjustment (if any) • Use predetermined adjustment calculations
