生长的阴影丨美国

和大多数城市的环境一样，坎布里奇的城市规划领域也不可避免地受到气候变化以及日益严重的社会经济不平等的影响。这些现象影响了那些居住在本没有为高人口密度规划的社区的人们，尤其在夏季，那里的居民们经常缺乏遮阳的基础设施。

Like most urban environments, Cambridge is subject to the inevitable effects of climate change and seemingly growing socioeconomic inequities within urban planning of the public realm. These phenomena often affect communities living in neighborhoods that were not originally planned for high population density and lack shaded infrastructure for their inhabitants during the summer months.

“生长的阴影”作为坎布里奇市倡导的“荫凉即社会正义”计划的一部分，为公众展现出一个很好的例子，证明了临时性的、低科技的、策略性的建筑如何通过景观的形式解决社会中不平等现象的问题。该项目是为孟加拉国移民社区设计的，该社区邻近的公共区域中明显缺乏荫凉的空间。作为户外社区空间，人们能够在夏季灵活使用该装置，享受他们应得的公共设施使用权。

Growing Shade, part of the “Shade is Social Justice” initiative promoted by the City of Cambridge, is a prime example of how ephemeral, low-tech, and tactical architectures can provide permanent solutions for inequities in our cities through the growth of landscape. The project, designed for a community of Bangladeshi immigrants who lack shaded spaces in their neighboring public areas, is defined as an outdoor community room with flexible use for user appropriation during the summer months.

这个由A1RE建造的社区空间被设计成日益稀少的树木的生长支架。空间由一组柱子组成，以结构的形式重新诠释了树桩，在建筑尺度上，这些结构通常用作树木幼苗的支撑物。柱子沿着圆周以不同的密度排列，围栏南部的柱子密度较高，北部的密度较低，进而以最有效的方式回应了北半球的太阳运动轨迹。

This community room, built by A1RE, is projected as a gradually disappearing framework for tree growth. The space is composed of a set of columns that reinterpret tree stakes, commonly used as support for young trees, at an architectural scale. These columns are arranged along a circumference in varying densities to most effectively address the sun path in the northern hemisphere, with a higher density of columns in the south of the enclosure and a lesser density in the north.

此外，这些柱子与轻质纺织品相连，在保护树木生长的同时提供了荫凉来激活户外空间。纺织品的设计注重安装的快速与便捷性，以便在秋冬季移除，并在春夏季再次安装，直到树木完全长大。当这些树苗足够茁壮茂盛时，它们将为社区创造出一个拥有永久遮阳的社区空间，而本项目的建筑结构将消失，可能会转移到另一个地点，为其他社区创造出额外的户外遮阳空间。

Moreover, these columns are connected with a lightweight textile that provides shade to activate the project while the trees grow. This textile is designed for quick and easy assembly as it will be removed during the fall and winter months and placed again during the spring and summer months until the trees are fully grown. Eventually, the trees will be large enough to provide the community with a permanently shaded community room, and the architecture will disappear, potentially moving to another site to create an additional shaded community room.

在不到一周的施工时间内，“生长的阴影”为解决社会正义议题提供了一个创新且直接的解决方案，它展示了非固定、低成本、临时性的建筑在缓解城市公共领域不平等方面的价值。

With a construction time of less than a week, Growing Shade is an innovative and immediate proposal that showcases the value of transient, low-cost, and ad-hoc architectures in mitigating inequities in the public realm of our cities.
