Verification relies on measured performance compared against established, normalized baselines.

This approach removes reliance on assumptions, estimates, or one-time assessments.

Energy performance changes as operating conditions, occupancy, and systems evolve.

Continuous measurement allows performance to be evaluated consistently as those conditions change.

Persistence is achieved when performance is monitored continuously rather than verified at a single point in time.

This enables early detection of drift and supports long-term program integrity.

Without verification and persistence, measured improvements cannot be trusted or sustained.

Consistent measurement provides the foundation for durable, defensible energy performance outcomes.
