During the implementation phase, what is developed in relation to monitoring and verification (M&V)?

• A. During the implementation phase, a list of specific instrumentation and data-gathering equipment that must be maintained at the site (correct)
• B. A plan for establishing performance baselines
• C. A plan for hand-off to facility management
• D. A plan for verifying the exterior envelope airtightness

Answer: (A)

The thing being developed is a concrete list of the instrumentation and data-gathering equipment that must be maintained at the site. This instrumentation backbone is essential for M&V because it specifies exactly what sensors, meters, data loggers or building management system interfaces, communication paths, data frequencies, and calibration and maintenance requirements will be used to monitor performance. With this list in place, you can collect reliable data to verify that the system operates as intended, track energy and water usage, and confirm that designed targets or savings are being achieved over the commissioning and post-occupancy periods. Other items like a plan for establishing performance baselines or hand-off to facilities management are important but belong to different stages or aspects of the project, and a plan for exterior envelope airtightness pertains more to design and pre-commissioning verification rather than the ongoing M&V data infrastructure.
