Measurement and Verification Real World Experience

Abstract

As a Senior Associate for Wood Environment and Infrastructure Solutions with over 39 years of experience as an energy engineering manager, a mechanical engineer, a design engineer, industrial plant engineer, and project manager Scott Walters, presents the real-world experience of measurement and verification. Mr. Walters has performed measurement and verification of a combined heat and power plant, multiple chiller plants, multiple air handling systems and multiple industrial process systems.  His experience on measurement and verification of HVAC systems and industrial systems reveals the following and more:

• Establish base lines for existing systems and identify benefits of new systems

1. Review OPR
2. Have a plan and know the contract
3. Know what you expect as benefits to know what and where to baseline

1. Motor amps tell the story
2. Bearings failing
3. Belt misalignment

• Identification of design and/or installation issues

1. Coils piped backwards
2. Fan types not matching submittals
3. Duct and pipe fittings impacting system pressure drop
4. Freeze protection valve positions

• Importance of component calibration

1. Sensors such as temperature, humidity, CO2 and process parameters

• System Performance to meet building or process requirements

1. Equipment performance at or near a design day or at peak process event
2. Equipment adaptable performance at low loads

• Reveal equipment schedule opportunities

1. The 5 second scheduling gremlin
2. Functional use changes catch it while you can; review the OPR

• The Value of M&V

1. A component of the commissioning process
2. Establishes base lines for performance contracts
3. Validates ongoing performance for ESPCs or UESCs
4. Preventive maintenance tools
5. Happy and productive occupants
