Energy Efficiency
The practice of using less energy to provide the same level of service or output in building operations.
Full Definition
Energy Efficiency in buildings refers to the practice of using less energy to provide the same level of comfort, lighting, and services. It involves optimizing building systems, equipment, and operations to reduce energy consumption while maintaining or improving performance. Energy efficiency measures include equipment upgrades, control optimization, scheduling, behavioral changes, and building envelope improvements. These measures contribute to lower operating costs, reduced environmental impact, and improved sustainability. Energy efficiency is often measured through metrics like Energy Use Intensity (EUI).
