In validating control strategy optimization, what evidence confirms performance improvements?

• A. Simulation results showing expected energy savings.
• B. FPT outcomes and M&V results.
• C. Vendor warranty documentation.
• D. Annual energy bill projection.

Answer: (B)

The key idea is using verifiable, measured evidence of how the control system actually performs after optimization. Functional Performance Testing shows the control sequences, sensors, actuators, and interlocks operating correctly in real conditions, confirming the optimization is implemented as intended. Measurement and Verification then quantify the real effects, comparing baseline energy use to post-implementation data with a repeatable method so you can prove savings are real and persistent. Simulation results only illustrate potential gains under assumed models and don’t prove actual performance. Vendor warranty documents don’t demonstrate energy performance changes, and annual energy bill projections are estimates, not measured outcomes. Together, FPT outcomes and M&V results provide concrete, verifiable proof of performance improvements.
