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

A project pursuing EA Credit Advanced Energy Metering may use which of the following to establish baseline consumption and demand data?

1. A calibrated energy model

2. Utility bill averages

3. Comparative building analysis

4. Historical usage patterns

The correct answer is: A calibrated energy model

A calibrated energy model is the most appropriate choice for establishing baseline consumption and demand data when pursuing EA Credit Advanced Energy Metering. This method allows for a detailed and accurate representation of a building’s energy use, taking into account various factors such as climate, occupancy, and operational characteristics. By simulating energy consumption under different scenarios, a calibrated energy model can provide reliable data that reflects actual performance, which is crucial for measuring improvements in energy efficiency over time. Using utility bill averages, while potentially helpful, can result in a lack of precision because they may include variations due to different tenant behaviors, occupancy rates, or seasonal fluctuations that do not accurately reflect the building's energy profile. Likewise, comparative building analysis might offer insights but lacks the specificity needed for an individual building's unique conditions. Historical usage patterns can provide some context but may not accurately represent current or future performance, especially if significant changes have occurred in the building or external environment. Therefore, the meticulousness of a calibrated energy model makes it the best tool for establishing a reliable baseline for energy monitoring and improvements.
