What does Energy Use Intensity (EUI) measure?

Energy Use Intensity (EUI) specifically measures the energy consumption of a building on a per-square-foot basis. It expresses how much energy is used within the building divided by its total floor area, typically reported in units like kBtu/sf/year. This metric allows for a standardized way to assess and compare energy performance across buildings of different sizes and types. It provides important insights into the energy efficiency of a building, allowing stakeholders to evaluate how much energy the building uses relative to its size.

By focusing on energy consumption rather than costs or emissions, EUI serves as a critical tool in energy management and benchmarking for buildings, making it easier to identify opportunities for improvement in energy performance. This focus on energy usage helps building owners and managers track energy efficiency measures and make informed decisions about retrofits and operational changes.
