LEED AP with Operations and Maintenance (O+M ) Practice Exam

Why is sub-metering important for energy performance credits?

1. To reduce installation costs

2. To enhance data accuracy for energy management

3. To decrease energy consumption

4. To simplify energy audits

The correct answer is: To enhance data accuracy for energy management

Sub-metering is crucial for energy performance credits as it significantly enhances data accuracy for energy management. By using sub-meters, specific areas or systems within a building can be monitored individually, allowing for precise tracking of energy usage. This granular level of detail enables facility managers to identify inefficiencies, assess the performance of different systems, and implement targeted interventions to improve overall energy efficiency. Moreover, accurate data from sub-metering aids in establishing baselines and measuring the impact of energy-saving initiatives over time. This detailed information is essential for making informed decisions about energy management strategies and resources, ensuring that they are both effective and efficient. When energy consumption is well-monitored, it can lead to better reporting, compliance with standards, and ultimately, a reduced carbon footprint. The other options do not address the direct benefits of sub-metering in relation to energy performance credits. While reducing installation costs, decreasing energy consumption, and simplifying audits can be related benefits, they do not capture the primary role of sub-metering in promoting accurate energy management data, which is vital for achieving energy performance recognition under LEED certification.
