Which statement accurately describes the Baseline Survey?

Which statement accurately describes the Baseline Survey?

• A. It assesses system effectiveness after operation
• B. It is conducted before operation to determine key parameters
• C. It measures general room air changes
• D. It plans the maintenance schedule

Answer: (A)

Baseline surveys establish the starting conditions before any operation or project begins, so you have a reference point for later comparison. They involve measuring key parameters that define how the system or environment currently behaves—things like ventilation rates, contaminant levels, energy use, occupancy patterns, and equipment loads. Having these baseline values lets you evaluate how changes, upgrades, or controls affect performance after implementation. Because this is a pre-change snapshot, it isn’t about assessing system effectiveness after operation—that would be a post-operation or performance verification step. It’s also broader than simply measuring general room air changes; it captures a set of essential conditions that characterize the system's initial state. It’s not primarily about planning maintenance schedules.
