节约能源的一种方法是使用智能绿色照明. 而照明通常被用来增强家庭的氛围, 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. 做出关于照明的绿色决定包括在可能的情况下使用日光, 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, 并通过让家具和窗帘远离窗户来促进最佳日光.
  • 使用浅色涂料和放置得当的窗户来增强室内的采光.
  • 使用百叶窗来控制眩光和热增益(尽管外部遮阳是控制热增益的最好方法-看 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, 确保这些都有独立方便的控制装置(如果适用的话还有调光开关),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.”
  • 金县禁止在垃圾中或在金县转运站和家庭危险废物设施中弃置荧光灯和荧光灯管.
  • Be sure to properly dispose of your magnetic ballasts. Use the Take it Back Network to determine where to take your old ballasts.
  • 西雅图市禁止在居住区或商业垃圾中以及西雅图中转站弃置灯泡/灯管.

以下是选择照明设备(包括固定装置)时的考虑事项, lamps (bulbs) and controls.

Additional Considerations

Fixtures

Existing

考虑重新利用你自己的灯具或寻找使用过的灯具,可以安装高效率的LED或CFL灯. 许多回收或二次使用的商店都有可以与现代照明配合使用的灯具, 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. 那些标榜为“气密”的产品可能仍然是漏气的. 这些固定装置就像小烟囱一样,会导致大量热量流失到阁楼或室外. 如果夹具没有额定与绝缘接触(ic额定), 在把隔热材料加到阁楼上之前,必须做额外的工作在它们周围建造盒子.

考虑用表面安装的LED灯具代替罐灯,模拟罐灯的外观和感觉. Ensure a good seal at the drywall before mounting the fixture.

Bulbs (general)

寻找能源之星标签的灯泡包装,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, 特别是目前当地的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

比较不同灯泡的色温,取决于你在哪里和如何使用灯光. 有些人喜欢温暖的温度,而凉爽或日光温度可能适合你的需要. 另外,在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灯泡相似的亮度,只是瓦数的一小部分.

Compact Fluorescent Lamps (CFL)

Ensure the CFL will fit in the socket you are using. 一些较宽的紧凑型荧光灯不适合低轮廓的墙壁或天花板烛台.

与led一样,明智地选择亮度和色温与你的品味相匹配的led.

Linear Fluorescent

旧的固定装置可以使用电子镇流器和磁镇流器. 磁镇流器往往嗡嗡作响,闪烁不定,效率低于电子镇流器. 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电子镇流器,它们不会闪烁.

将旧的T12管荧光灯换成32瓦的t8或LED管替换灯泡.

Incandescent

The U.S. is phasing out incandescent bulbs. 使用节能灯作为你的默认灯泡,并升级到led的成本效益. 节能灯的使用寿命是白炽灯的10倍,现代节能灯的大小和颜色与白炽灯相当. led的使用寿命是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, 你可以根据自己的需要改变灯泡的亮度,延长灯泡的寿命.

无论你买哪一种,一定要选择调光器兼容的灯泡.

Outdoor Controls

户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.
