本文件规定了非住宅建筑内提供一般照明的照明系统的能源性能评估方法，以及计算或测量建筑内照明所需或使用的能源量的方法。 本文件不包括照明要求、照明系统的设计、照明装置的规划、照明设备（灯具、控制装置和灯具）的特性，以及用于展示照明、办公桌照明或家具内置灯具的系统。本文档不提供照明场景设置动态模拟的任何程序。

This document specifies the methodology for evaluating the energy performance of lighting systems for providing general illumination inside non-residential buildings and for calculating or measuring the amount of energy required or used for lighting inside buildings. This document does not cover lighting requirements, the design of lighting systems, the planning of lighting installations, the characteristics of lighting equipment (lamps, control gear and luminaires) and systems used for display lighting, desk lighting or luminaires built into furniture. This document does not provide any procedure for the dynamic simulation of lighting scene setting.
