Modernizing the Hutong

MODERNIZING THE HUTONG | 使胡同现代化 Modernizing the Hutong extracts the positive elements from traditional hutong neighborhoods (pedestrian-orientation, a tight-knit community, and a mix of residential and commercial activity) and transforms it into a modern ecocity by increasing density and commercial opportunities and reducing energy use. We use the canal as a central organizing feature, creating a waterfront and a central park for the neighborhood. 现代化胡同吸收了传统胡同街区的优秀传统，（例如步行导向、联系紧密的街区，商住混合的活动模式等），并且在我们的设计中，我们 把它转变成一个现代的、生态的街区，增加了密度和商业机会，降低了能耗。我们利用水渠作为组织街区结构的关键要素，为街区创造了 水岸和中央公园。

1. The New Low Carbon Cluster successfully achieves to have an energy performance comparable to that of a traditional Hutong even when it has five times the density and twice the amount of open space.

2. Formally, the New Low Carbon Cluster represents a departure from the conventional FAR - coverage spectrum (where FAR and coverage are inversely proportional).

Thanks to a height gradient, high rise and low-rise structures are dispersed throughout the cluster allowing for both a high FAR and a high coverage. Stimulating urban space is not sacrificed in the name of energy efficiency.

1. 这个新的低碳组团的能源消耗量可以与传统的胡同相媲美，然而，它的密度则 是胡同的五倍，公共空间面积则是胡同的两倍。 2. 这个低碳组团跳出了传统意义上容积率和建筑密度之间成反比这一定律的束缚 由于高差的存在，高低错落的建筑分布在整个组团中，使得组团中既拥有高 的容积率，又拥有高的建筑密度。激活城市空间并不意味着牺牲能源效率。

3. The city of Jinan is located midway between Beijing and Shanghai. The new development will be strategically located along one of the stops linking the two cities.

4. The master plan is articulated around a system of open spaces, green pathways linking them and activity nodes on each transit intersection. This networked scheme generates and disperses activity across the whole site.

5. Renewable energy forms are physically embodied in urban forms and building systems, but the relationships between these are not linear. A typical cross section illustrates how several systems (i.e. grey water management, geothermal and solar heating) exchange energy through an integrated whole.

3. 济南坐落于上海和北京之间。这个具有战略意义 的新站将会坐落于两个重要城市间，作为连接它们 的重要枢纽。 4. 总图中，一个明晰的开放空间系统贯穿其中，绿 色廊道连接了这些开放空间，每个活动地点都传递 着通达性。这个开放网络生成了人类活动，并把它 们散布在整个地段中。

5. 从城市形态中和建筑系统中，我们可以看出可更 新的能源形式已经呈现出来了，然而，它们之间的 关系不是线性的。一个精心设计的交织网络和非线 性的关系创造出了反馈的环路，把能源系统连接在 一起。 个典型的剖面阐释出这些系统之间是如何通过一个 整合的体系交换能量的。（例如水管理系统，地热 系统，太阳能系统。）

The connections between form, on both urban and building scale, and energy use are complex and non-linear.

The many systems are interconnected. For example, bioswales provide open space, filter greywater, catch stormwater and reduce urban heat island effect in addition to promoting biodiversity.

MODERNIZING THE HUTONG | 使胡同现代化 Low Carbon Cluster 低碳组团 Our cluster shows a gradient in building height-- from the high-rise around the main commercial street and transit stop to mid-rise residential and local commerce.

This diversity creates a variety of different types of spaces from dense office buildings to quiet residential streets and public spaces. This scheme is applicable to the whole city, where the dense, high-rise areas create transit nodes where the light rail, streets and pedestrian ways come together and transition to lower density farther way from the light rail stops.

The variety of building types also allows a high percentage of open space, leaving space for public plazas, geothermal wells and bioswales. 我们的组团在建筑高度上呈现出梯度变化，从主要商业街道、交通站的高层， 变化到中层的居住区和小区级商业。这种多样化创造了多样的空间形式，从紧 凑的办公建筑到宁静的居住街道和公共空间。这一主题在整个城市中都得到了 运用，高密度、高层的街区使得交通站的轻轨、街道、步行道得以汇合，并且 连接了远处中密度的街区。 多样性的建筑样式还使得更多的空间留给了开放空间，用于公共广场、地热井 、生态过滤系统的建设。
