LEED AP Building Design and Construction (BD+C) Practice Exam

Which of the following is a benefit of commissioning?

1. Increased building floor area

2. Reduced contractor callbacks

3. Higher energy consumption

4. Delayed project timelines

The correct answer is: Reduced contractor callbacks

Commissioning is a systematic process that ensures a building’s systems are designed, installed, and function according to the owner’s operational requirements. One key benefit of commissioning is the reduction of contractor callbacks. This occurs because commissioning involves thorough testing and verification of systems—such as HVAC, lighting, and plumbing—throughout the construction phase. By addressing issues and ensuring that systems operate correctly before the project is handed over, commissioning minimizes misunderstandings and errors that might necessitate extensive corrections later on. In contrast to the other options, increased building floor area isn’t a direct benefit of commissioning, as it primarily focuses on system performance rather than the physical layout of a building. Higher energy consumption contradicts the fundamental goals of commissioning, which strive to optimize energy use through proper system operations. Delayed project timelines may occur due to insufficient coordination or budget overruns, but commissioning typically aims to mitigate these risks by ensuring that all systems are functioning properly in advance, consequently helping to adhere to project timelines instead of delaying them.
