| Good indoor environmental quality requires properly focused lighting at the right level and quality. One lighting strategy that green buildings incorporate is daylighting, which refers to intentionally allowing natural light into a space through windows, skylights, or other transparent or translucent openings. Proper daylighting designs rely primarily on indirect and diffused light rather than direct sunlight, and they often include a shading system to prevent glare and unwanted heat gain. Use of natural daylight can help reduce the need for electric lighting, thus reducing energy use. In addition to admitting daylight, windows that let people focus their eyes across a longer distance and see the outdoors may also play a role in occupants' comfort. | 良好的室内环境质量需要在正确的水平和质量上提供适当聚焦的照明。绿色建筑采用的照明策略之一是采光（daylighting），即通过窗户、天窗或其他透明或半透明开口有意让自然光进入空间。合理的采光设计主要依赖间接和漫射光而非直射阳光，且通常包括遮阳系统以防止眩光和不必要的热增益。使用自然采光有助于减少对电力照明的需求，从而减少能源使用。除了引入日光之外，能够让人们的眼睛进行远距离聚焦并看到户外的窗户，也有助于使用者的舒适度。 |
| In order to effectively incorporate daylight, elements must be appropriately sized and placed. To most effectively harvest daylight and bounce and diffuse natural light, daylighting utilizes: | 为了有效地引入日光，各元素必须具有合适的尺寸和位置。为了最有效地收集日光并反射和漫射自然光，采光设计会利用： |
| Components of effective daylighting: | 有效采光的组成部分： |
| • High-placed windows or skylights | • 高位窗户或天窗 |
| • Devices to reflect daylight into an indoor space | • 将日光反射到室内的装置 |
| • Light-colored paint and materials | • 浅色涂料和材料 |
| • Lighting controls with daylight sensors | • 带日光传感器的照明控制 |
| Lighting design must control glare and allow colors to appear vibrant and true to their actual hue. These lighting quality requirements apply to all sources of light, whether daylight or electric. | 照明设计必须控制眩光，并使颜色显得生动真实。这些照明质量要求适用于所有光源，无论是日光还是电力照明。 |
| Decarbonization: The use of daylight can reduce the need for electric lighting, thus decreasing energy use. | 脱碳：使用日光可以减少对电力照明的需求，从而降低能源使用。 |
