在整个过去的10年 LEED（能源与环境设计先锋奖）已经发展成为一种有效的解决方案，楼宇业主，以减少开支并限制其建筑对环境的影响。虽然许多LEED项目采取的典型商业，机构，政府和医疗机构的形式，LEED提供了许多其他行业的分化，并产生一个真正难得的项目，莫过于在双橡园垃圾填埋场格兰姆斯县，能力这实现LEED银认证。
<强>填埋是在经工程改造的和自足的站点存储废料以受控环境分解。 The term “landfill” implies a simple earth excavation filled with garbage. While crude waste disposal practices occurred over many previous decades, modern landfills are carefully prepared structures with many common design features. Many landfills safely serve a secondary function such a recreational park or golf course when their maximum capacities are reached. Most landfills are solid waste landfills that receive municipal refuse originating from homes, businesses and institutions. There are some specialized landfills that receive specific industrial wastes including liquids. Even within solid waste landfills, liquid containment is essential because of leachate production. Leachate is an organic waste liquid, a by-product of solid waste moisture and decomposition, mixed with any precipitation or groundwater infiltrating through the landfill. Modern landfill designs will include a bottom layer, a leachate recovery system, a surface cap, and gas release capability, as methane is generated within landfills as organic wastes decompose.
