芳草地项目是从2001年就开始孕育的一个非常有雄心的项目，项目旨在打造中国最绿色的节能商业综合体之一，这个项目最终于2010年十年之后完成。项目标新立异，是同种设计中的首例，一个微环境表皮包裹占地230000平方米的商业，办公和酒店项目，项目克服众多的技术和法规上的挑战，最终以独特可辨的造型及绿色标准成为北京的地标。项目2010年荣获美国绿色建筑委员会的LEED白金认证。

这个项目的重点是保护周边居民的自然光和通风来源，在毫无阻挡的日光角度及严格的高度限制下，一个金字塔表皮得以形成。设计将规划的限制性因素转化为项目的有利条件，从而创造出环保的开阔的空间，它免受噪音，污染及过强光照的影响，所有上层的办公及酒店都有室外的景观区，它们在四季呈现出不同的美景。

设计围绕四个单独的建筑展开，它们被一个钢铁玻璃和ETFE微环境表皮全全包住。整个建筑低于地面九米，这样热气从顶层逃离，新鲜空气因为热堆积效应从下沉花园引入。建筑的每层都享受自然通风，相比于传统的建筑，芳草地能够在夏季能够节能16%，而冬季则达83%。

在内部建筑之间有一个235米长的人行桥，它斜线连接首层的对角，钢铁悬挂支撑的人行桥为人们提供穿越城市区的一个公共道路。从桥上经过人们能感受到一个充满现代艺术品及街道活动的与众不同的城市空间。芳草地项目打造了北京CBD中心区独特的城市体验。

The Parkview Green project， conceptualized in 2001 to create one of the greenest， energy-efficient， dynamic mixed-use commercial developments in China， finally completes after 10 years of gestation. Being one of the first of its kind， the microclimatic envelope that encloses 230，000 square metre of retail， offices and hotel project overcame many technical and statutory challenges to become a unique landmark in Beijing， for its easily recognizable architecture and its Green credentials. The project has been certified Platinum under the LEED assessment by the US Green Building Council in 2010.

The raison d’être of the project is the preservation of natural light and ventilation for every neighbouring household surrounding the site. Under the unhindered daylight angle and restrictive heights a pyramidal envelope is formed. The concept turns these planning constraints into the project’s main asset. Creating an environmentally tempered voluminous space devoid of noise， pollutants and radiant heat from the sun， all upper storeys of offices and hotel are provided with extended outdoor landscaped areas at every floor that are usable all year round.

The concept centres around 4 independent buildings being entirely enclosed by a steel， glass and ETFE microclimatic envelope. The whole building is sunk 9m below ground level. By allowing hot air to escape at the pinnacle fresh air is drawn from the sunken garden through natural heat stack effect. Every level of the building enjoys natural ventilation when the environmental conditions are favorable. Significant energy savings has been achieved when compared against conventional buildings， between 16% in the summer and 83% in the winter.

Between the buildings a 235m span footbridge connects the diagonally opposite corners of the site at ground level. The cable suspended footbridge provides a public access through the urban block. Walking over the bridge reveals a totally different urban space filled with contemporary artwork and street activities. The Parkview Green is a unique urban experience in the heart of the CBD in Beijing.
