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

Which of the following is NOT a component of monitoring-based commissioning (MBCx)?

1. Real-time energy analysis

2. Energy modeling simulation

3. Permanent energy monitoring systems

4. Ongoing commissioning

The correct answer is: Energy modeling simulation

Monitoring-based commissioning (MBCx) is an approach focused on utilizing real-time data to optimize building performance and enhance energy efficiency. Each of the components plays a crucial role in the MBCx process. Real-time energy analysis allows for the immediate assessment of energy use and performance, enabling building operators to make timely adjustments and improvements based on current conditions. This is an essential feature of MBCx. Permanent energy monitoring systems are also fundamental, as they provide continuous data collection that informs ongoing performance evaluations well after the initial commissioning phase. These systems facilitate the identification of trends, anomalies, and opportunities for further energy savings. Ongoing commissioning refers to the continuous improvement processes that follow the initial commissioning efforts. It ensures that the building continues to operate efficiently over time as occupancy and usage patterns change. In contrast, energy modeling simulation is typically conducted during the design phase of a building project to predict performance under various scenarios and is not part of the real-time assessment in MBCx. While valuable in its own right, it does not involve the continuous, real-time monitoring aspect fundamental to MBCx. Thus, it is the element that does not align with the core practices of monitoring-based commissioning.
