ASLA GREEN ROOF

Washington, DC (2005–2006)

Located on the rooftop of the headquarters of the American Society of Landscape Architects in the heart of Washington D.C., the ASLA Green Roof project transformed an existing 3,000 square foot roof into an expressive display of green roof technology that supports an active social space.

The barrel-shaped mounds at the north and south ends of the roof create new horizons for visitors, clearing the immediate urban foreground and focusing views on the more distant Washington skyline. The two lightweight mounds present two different green roof types: one is “extensive,” including low plants that require minimal soil depth; the other is “semi-intensive,” involving taller plants that require a deeper soil base. The higher growth on the semi-intensive mound rises up to meet the parapet edge and is visible from the street level, announcing the green roof and ASLA’s green agenda to public passersby. Balancing social use and ecological benefit, the main central walking surface is a metal grille suspended above a layer of living plants.

The Green Roof will be a demonstration project for future ASLA efforts to teach the benefits of green roof technology, and so it is designed with research and education in mind. The plant palette is more ecologically and environmentally varied than the sedum monoculture that is typical of many green roofs. The success of each plant species is being monitored in order to identify a more diverse palette of plants that could survive on an urban rooftop without active maintenance after the first several years of establishment. Monitoring and recording elements will also track the absorption of water and the temperature of the rooftop.

The ASLA Green Roof received a 2007 New York ASLA Design Honor Award .

美国景观设计师协会屋顶绿化

华盛顿（2005-2006）

位于美国景观设计师协会在华盛顿的总部的屋顶，在美国景观设计师协会屋顶绿化工程改造现有的3000平方英尺的屋顶到屋顶绿化技术的表现显示屏，支持积极的社会空间。

酒桶形土墩在屋顶的南北两端建立供游人新的视野，清除眼前的城市前景和专注于更遥远的华盛顿天际线景观。这两个轻量级的土堆目前两种不同的绿色屋顶类型：一种是“粗放型”，包括低的植物，需要最少的土层;另一种是“半精”，涉及较高的植物，需要更深的土壤碱。在半精阜的较高增长上升到满足栏杆边缘，从街道层面可见，宣布屋顶绿化和美国景观设计师协会的绿色议程对公众路人。平衡社会利用和生态效益，主要的中央行走表面是金属格栅悬挂上面有一层活的植物。

绿色屋顶将是一个示范项目，未来美国景观设计师协会的努力教的屋顶绿化技术的优势，因此它是设计时考虑到研究和教育。该工厂的调色板比单作景天是典型的许多屋顶绿化更生态和环境各不相同。各植物物种的成功，以确定植物的最初几年建立后，可以生存在城市的屋顶无有效维护了更多样化的调色板进行监测。监测和记录元件也将跟踪的水吸收和屋顶的温度。
