An energy performance indicator is a quantitative measure used to assess energy efficiency. This option is correct because energy performance indicators provide numerical data that allows for objective evaluation and comparison of energy usage across different systems, buildings, or processes. By using these indicators, energy auditors can identify areas where energy efficiency can be improved, set benchmarks, and monitor progress over time.

Energy performance indicators often include metrics such as energy use per square foot, energy cost per unit of production, or energy consumption relative to occupancy levels. These indicators help in tracking performance not only against historical data but also against industry standards and best practices.

While qualitative measures, regulatory requirements, and historical comparisons play important roles in understanding energy performance, they do not serve as direct indicators of efficiency in the same way that quantitative measures do. Quantitative assessments are essential for making informed decisions about energy management strategies and for verifying improvements in energy performance.
