Green Roofs and LEED Certification

How exactly, can a green roof help a facility attain LEED certification?

Following are five major categories of the USGBC LEED rating system, along with the potential "points" that can be earned by

installing a green roof.

屋顶绿化及LEED证明

屋顶绿化如何帮助设施获得LEED证明的呢？下面是美国绿色建筑委员会的LEED打分系统的5个主要类别，连同通过屋顶绿化可能获得潜在的‘分数’。

过屋顶绿化可能获得潜在的分数。

美国绿色建筑委员会

Leadership in Energy and Environmental Design (LEED)

能源及环境设计指引

Reduced Site Disturbance -Potential Rating: 1 point.

Installing a green roof may apply to protecting or restoring the open space consumed by a building's footprint. The roof also provides a habitat for birds and insects, and promotes biodiversity.

减少现场扰动－潜在分数：1分

进行屋顶绿化可以保护或还原由于建筑留下的开放空间。这样，屋面也为鸟类及昆虫提供了栖息地，进而使生物多样化。

Storm-Water Management -Potential Rating: 1 to 2 points.

Green roofs significantly help reduce storm-water discharge. The roofs may also provide storm-water treatment through their ability to remove contaminants and other pollutants.

1到2分。

雨水管理－潜在分数：分

屋顶绿化能显著减少雨水排放量。绿化屋面有能吸附有害及污染物质的能力从而提供对雨水的处理作用

Heat Island Effect -Potential Rating: 1 point.

Green roofs help reduce rooftop temperatures in summer. When temperatures reach 80°F outside, roof temperatures can climb as high as 180°. This causes a "heat island" effect in large urban areas, increasing the heat -and the resulting need for air-conditioning.

热岛效应－潜在分数：1分

屋顶绿化能在夏天帮助降低屋面温度当外界温度达到华氏度时屋顶绿化能在夏天帮助降低屋面温度。当外界温度达到80华氏度时，屋面的温度可以攀升至高达180华氏度。这就在大的城市中心导致了一种‘热岛效应’，增加热量－并且导致使用空调。

能源及环境设计指引

Water-Efficient Landscaping -Potential Rating: 1 to 2 points.

Green roofs can be designed to require very little (or no) irrigation. Drought-resistant plants can be selected, water can be reused and gray-water (waste water that can be used for irrigation) systems can collect excess runoff after storms and use it to water used for irrigation)systems can collect excess runoff after storms and use it to water the plants.

增加水的利用率的绿化－潜在分数：1到2分

屋顶绿化可以设计成只需要少量灌溉或根本不需要灌溉的类型。可以屋顶绿化可以设计成只需要少量灌溉或根本不需要灌溉的类型可以选择抗干旱的植物，水分能够再利用并且利用系统收集从屋面排走的雨水－所谓的‘灰水’（能作为灌溉用的废水）来灌溉植物。

Optimize Energy Performance -Potential Rating: 1 to 8 points.

As mentioned earlier, green roofs help reduce energy demand by more than 50 percent in many types of structures. Thus, smaller, less costly cooling systems may be sufficient.

优化能源利用－潜在分数：1到8分

在早先提到的，屋顶绿化能帮助降低能源需求。在不同的构造做法中，

有时甚至能降低到50％。这样，用一些更小的，更便宜的制冷系统就足够了。
