NEW QUESTION # 145
How can commissioning reduce the life-cycle cost to owners and operators?
Answer: B
Explanation:
1) Life-Cycle Cost Reduction via Commissioning (CEM Guidance)
The AEE CEM Body of Knowledge emphasizes that commissioning reduces total life-cycle cost, not just first cost, through multiple pathways.
2) Evaluation of Each Option
* A. Reduce the cost of change orders during construction
* Early detection of design and coordination issues reduces rework.
* B. Improve the performance of energy systems
* Ensures systems operate at intended efficiency.
* C. Improve the satisfaction of building occupants
* Better comfort reduces complaints and operational disruptions.
* D. Improve the effectiveness of operations and maintenance
* Training and documentation improve long-term reliability and efficiency.
All are documented commissioning benefits in AEE CEM training materials.
