Certain organizations,like the U.S.Green Building Council (USGBC) have come forward
as strong proponents of living roofs.
Through its Leadership in Energy and Environmental Design?(LEED) certification
program,architects/engineers can pursue sustainable design and earn points towards
project certification.Green roofs can contribute towards up to 14 points with LEED-NC
(New Construction) Version 2.2.(refer to table on next slide).
Points are awarded for numerous benefits including stormwater management,since the
effect of a green roof is that it decreases the impervious surface of a site.A specific
credit addressing reduction of heat islands is available and green roofs qualify as long
as they cover at least 50% of the roof surface.In addition,some green roof
manufacturers use recycled content in the waterproofing membrane and other
components that contribute to the granting of additional points towards certification.
Vegetative roofs can contribute to providing points for supplying materials within a
500-mile radius of the site,and also count for the reduction of site disturbance.

像美国绿色建筑委员会等机构已经变成了生态屋顶的强烈支持者.（注：用Google图片搜了一下living roof,可以知道指的是种植了绿色植物的房顶,我不知道生态建筑学上的术语是什么,权先翻作生态屋顶吧.）
通过其“能源及环境设计领军者”认证项目,建筑师或工程师可以追求可持续型设计,为工程认证赢得加分.根据“能源及环境设计领军者-新结构”版本2.2的规定（参见下一页表格）,生态屋顶最多可为设计赢得14分的加分.
加分主要根据几项优点.其中包括暴雨雨水管理,因为生态屋顶的效用之一就是减少了非渗透表面的面积.还有其减少了热岛效应也为之赢得特别加分,绿色植物至少覆盖了屋顶50%的面积.另外,有些绿色屋顶的生产商采用可循环防水薄膜材料和其他内容,也能为设计额外加分.
