What does DN stand for in commissioning terminology?

• A. Design Narrative
• B. Design Notation
• C. Documentation Network
• D. Design Ministry

Answer: (A)

In commissioning terminology, DN stands for Design Narrative. This document communicates the design intent, operating strategies, and performance criteria for building systems. It explains how each system should behave, the sequence of operations, and what outcomes to verify during testing. Having a Design Narrative keeps the commissioning team aligned with the designer’s goals, guiding test plans and acceptance criteria, and providing a clear reference during handover. The other options don’t capture the idea of describing how the design should operate or the sequence of operations, so they aren’t the standard terms used in this context.
