What role do as-built drawings play in the NEBB CP process?

• A. They document the actual installed configurations and are used to verify duct runs, fittings, and zone layouts for accurate balancing.
• B. They are optional and rarely used in NEBB CP.
• C. They only show the design intent and are not used for verification.
• D. They are used to determine energy consumption.

Answer: (A)

As-built drawings provide the real-world snapshot of the installed system. In the NEBB CP process, these drawings are used to verify that what’s actually built matches what was intended, by showing the true duct routes, fittings, and zone layouts. This lets the balancer locate test points accurately, confirm damper positions, and ensure that the measurement data reflect the exact installed configuration. Any field changes or modifications are captured in the as-built, which is essential for interpreting results, validating that the balance achieves the design intent, and supporting future maintenance or rebalancing. They’re not optional, and they’re not just about design intent; they’re the reference you rely on to verify accuracy. They also don’t directly determine energy consumption, though the real configuration they document will influence energy performance.
