What does the energy utilization index (EUI) measure?

The energy utilization index (EUI) specifically measures the total energy consumption of a building in relation to its size, expressed as energy per square foot. This metric is valuable for assessing the energy performance of a building by normalizing energy use to a standard measurement (square footage), which allows for straightforward comparisons between different buildings or facilities regardless of their size. By understanding the EUI, energy managers and building operators can identify opportunities for energy efficiency improvements while also benchmarking against industry standards.

While other choices address different aspects of energy metrics, they do not encapsulate the specific purpose of the EUI as accurately as total energy consumption per square foot does. This clarity in definition makes the correct choice an important concept for anyone looking to enhance energy efficiency within buildings.
