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

**K. Quinn Hart, PE**

## 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**

| Lighting | DX Unit/Heat Pump Replacement |
| --- | --- |
| Constant Load Motor Retrofits | EMCS |
| Variable Speed Drives | FM Control Systems |
| Boiler Replacement | Chiller Plants |
| Infrared Heating | Building Envelope |
| Steam Trap Systems | Propane-Air Plants |
| Chiller Replacements | Heat Plant Decentralization |
| Cooling Tower Replacements | HVAC Controls/Retrofits |
| Plate & Frame Hx Installation | Thermal Storage Systems |

**Notes:**

Energy Conservation Projects include:
Lighting, Constant Load Motor Retrofits, Variable Speed Drives, Boiler Replacement, Infrared heating, Steam Trap Systems, Chiller Replacements, Cooling Tower Replacements, Plate Heat Exchanger Installation, DX Unit/Heat Pump Replacement, Energy Management & Control Systems, FM Control Systems, Chiller Plants, Building Envelope, Propane-Air Plants, Heat Decentralization, HVAC Controls/Retrofits and Thermal Storage Systems.

## 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**

## 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**

## 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**

During the cooling season heat is supplied to reheat coils by the same system.  Reduced pressure steam provides humidification in winter. DHW by other means.  |

## 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**

| X  | 44000 | Gas DWH Heater | Summer boiler For DWH
 |  |
| X-1
 | 14000 | HW boiler | Requires IR for shop area and POU  WH in toilets | Remove HX  and pipe new installation direct to AHUS.  |

 | Steam Boiler

 | Requires steam year around for reheat humidity control, DWH and autoclaves | Make Mech room walls & Ceiling compliant with fire code. Pipe to existing units replace interior traps.  |

## Post ECP Performance Requirements

**Bldg No.**

**Size MMBTU**

**Boiler Efficiency**

## 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**

## 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**** **

## Project Acceptance

**Boiler Test Results**** **

## 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**
