Full Form of EUI
What is EUI?
Energy Use Intensity (EUI) is a metric that expresses the total energy consumption of a building or facility per unit of floor area over a specified period, typically measured in kilowatt-hours per square meter per year (kWh/m²/yr) or British Thermal Units per square foot per year (Btu/ft²/yr). In India, EUI is a key performance indicator for evaluating and benchmarking energy efficiency in commercial, residential, and industrial buildings, especially under programs like the Bureau of Energy Efficiency (BEE) star rating for buildings and the Energy Conservation Building Code (ECBC). It is used by architects, facility managers, and energy auditors to identify savings opportunities and track improvements over time. For students preparing for competitive exams such as GATE, IES, and energy management certifications, understanding EUI helps in grasping energy auditing concepts and sustainable design. The metric is also central to green building certifications like LEED and GRIHA, making it relevant for real estate and infrastructure projects across India. A lower EUI indicates better energy performance and reduced operational costs.

Example
The Energy Use Intensity of the new IT park in Bengaluru dropped by 25% after implementing solar panels and efficient HVAC systems, aligning with the BEE's 5-star rating requirement.
EUI — frequently asked questions
What is the full form of EUI?
EUI stands for Energy Use Intensity, a metric that quantifies energy consumption per unit area of a building over a year.
How is EUI calculated in Indian buildings?
EUI is calculated by dividing total annual energy consumption (in kWh) by the gross floor area (in m²), often adjusted for occupancy and climate zones as per BEE guidelines.
What is a good EUI value for an office building in India?
A good EUI for a commercial office in India is below 90 kWh/m²/yr for a 5-star rated building under BEE, though values vary by climate and building type.
