在家里节约能源的一种方法是使用智能绿色照明. 而照明通常用于增强家庭的氛围, it is also a key opportunity for reducing your energy bills. Green lighting is about more than just switching the bulbs; it is also about making choices that minimize your energy and resource footprint in as many ways as possible. 做出绿色照明的决定包括尽可能地利用日光, taking care when installing and disposing of lighting products, and choosing the right equipment (e.g. 固定装置，灯泡，控制装置)在你家里合适的地方. Keep the following considerations in mind before you design, install, and dispose of lighting products.

Daylighting

  • Take advantage of natural daylight in your home. Keep lights off when daylight is sufficient, 让家具和窗帘远离窗户，促进最佳采光.
  • 使用浅色油漆和位置合适的窗户组合来增强家中的采光.
  • 使用百叶窗来控制眩光和热量增加(尽管外部遮阳是控制热量增加的最好方法) Heating, Cooling, and Ventilation

Lighting installation

  • Seal any penetrations in the ceiling or exterior wall. Use low-VOC caulk rated for electrical boxes.
  • Ensure each fixture group has its own control in each room. For example, in a room with a central pendant, accent lights and task lighting, 确保这些都有独立的和方便放置的控制(和调光开关在适用的地方)，让你的家人只使用必要的光量.

Lighting disposal

  • Follow the EPA’s guidelines for Cleaning Up a Broken CFL. 紧凑型荧光灯和线形管荧光灯都含有汞.
  • King County makes it easy for you to find Fluorescent Bulb & Tube Recyclers through the “Take it Back Network.”
  • 金县禁止在垃圾或金县中转站和家庭危险废物设施中处置荧光灯泡和荧光灯管.
  • Be sure to properly dispose of your magnetic ballasts. Use the Take it Back Network to determine where to take your old ballasts.
  • 西雅图市禁止在住宅或商业垃圾和西雅图转运站处置灯泡/灯管.

以下包括选择照明设备(包括固定装置)时的考虑因素, lamps (bulbs) and controls.

Additional Considerations

Fixtures

Existing

考虑重新利用你自己的灯具，或者寻找可以安装高效LED或CFL灯的旧灯具. 许多二手商店都有可以与现代照明配合使用的固定装置, while also adding character to your project. See Resources for Salvage Stores.

New

Look for the ENERGY STAR label on new fixtures.

Can Lights

If possible, avoid recessed lights. 那些被宣传为“无懈可击”的产品可能仍然很漏水. 这些装置就像小烟囱一样，会导致大量的热量流失到你的阁楼或房子的外面. 如果灯具不额定与绝缘接触(ic级), 在阁楼上添加绝缘材料之前，必须在它们周围建造额外的盒子.

考虑用表面贴装的LED灯具替换易拉罐灯，模仿易拉罐灯的外观和感觉. Ensure a good seal at the drywall before mounting the fixture.

Bulbs (general)

寻找灯泡包装上的能源之星标签，以确保高性能.

Consider replacing incandescent light bulbs with LEDs or CFLs.

The economic payback on many of these lights is very short, 特别是目前当地公用事业照明折扣计划. Check out this Guide to More Efficient and Money Saving Bulbs external link before shopping.

Bulbs by type

LED

根据你使用光源的地点和方式，比较不同灯泡的色温. 有些人喜欢温暖的温度，而凉爽或白天的温度可能适合你的需要. 更换灯泡时也要注意亮度——led可以提供与节能灯或其他类型的节能灯相似的亮度水平，而瓦数只是节能灯的一小部分.

Compact Fluorescent Lamps (CFL)

Ensure the CFL will fit in the socket you are using. 一些较宽的节能灯不适合低轮廓的墙壁或天花板壁灯.

与led灯一样，明智地选择与你的口味相匹配的亮度和色温.

Linear Fluorescent

较旧的装置可能使用磁性镇流器和电子镇流器. 磁性镇流器倾向于嗡嗡声和闪烁，比电子镇流器效率低. You can use your smart phone or camera external link to check what kind of ballast you have. 让电工把这些转换成不闪烁的电子镇流器吗.

将旧的T12灯管换成32瓦t8或LED灯管.

Incandescent

The U.S. is phasing out incandescent bulbs. 使用cfl作为您的默认灯泡，并在成本效益高的地方升级到led. 节能灯的寿命是白炽灯的10倍，现代节能灯的尺寸和颜色与白炽灯相当. led的寿命是cfl的5倍，是白炽灯泡的25倍.

Controls

General

Consider the best control for a light; use timers or occupancy sensors / motion detectors, especially in rooms where lights are frequently left on.

Dimmers

Dimmers can help save energy, 允许您改变光量，以满足您的需要，延长灯泡的寿命.

无论你买哪种类型的灯泡，一定要选择与调光器兼容的灯泡.

Outdoor Controls

室外照明最好由运动传感器或黄昏传感器控制. Make sure dusk sensors are CFL and LED bulb compatible.
