Hout Architecture公布了他们在达卡的BERC总部的详细方案，该方案在孟加拉国能源管理委员会总部的设计国际竞赛中获得了优秀奖。该项目位于Sher-e-Bangla Nagar地区的中心，沿着东西方向，与Louis Kahn设计的National Parliament House相邻。

Hout Architecture has released details of their BERC Headquarters in Dhaka, which received an honorable mention in an international competition for the design of the Bangladesh Energy Regulatory Commission head office. Located in the center of the Sher-e-Bangla Nagar area, orientated along an east-west direction, the program connects to the National Parliament House, designed by Louis Kahn.

BERC建筑的设计是对当地地区的场地条件、织造影响和重叠方案的单一回应，同时缓解了极端气候条件。建筑的特殊表达反映了当地的环境，并建立在Dhaka建筑的现代建筑遗产之上。

The design of the BERC building is a singular response to local and regional site conditions, weaving influences and overlapping programs while mitigating against extreme climate conditions. The particular expression of the building is reflective of the local context and builds upon an established modern architectural heritage of public buildings in Dhaka.

该地块的形状严重影响了该方案的矩形占地面积，导致沿着运河的西面海拔高度扩大。采用一个被动的策略结合了阴影，植被，空气循环和水的收集来减少对热量的吸收。形状为倒拱的预制混凝土花槽收集水分使绿色植物能够茁壮成长，而纤细的垂直构件起到了防晒的作用，同时也为攀缘植物提供了支撑。

The shape of the plot influenced heavily on the scheme’s rectangular footprint, resulting in an expansive west elevation along the canal. To mitigate against massive heat gain, a passive strategy combines shades, vegetation, air circulation, and water harvesting. Precast concrete planters shaped as inverted arches collect water and allow the greenery to thrive, while thin vertical members provide a sunscreen as well as a backing for climbing vegetation.

花盆和围护结构之间的空隙允许空气在茂盛的绿色层和围护结构之间循环，使得凉爽、干净的空气能够从外立面输送到建筑物内，从而将西立面变成一个巨大的空气和光线过滤器。

在内部，倒置的拱门在公共空间上方形成了伏的天花板，同时在建筑的南北两端都创造出相互连接的楼层，在空中创造出具有独特形式品质的公共房间。

A gap between the planters and envelope allows air circulation between the lush green layer and envelope, moving cool, clean air up the facade and into the building, thus turning the west elevation into a giant filter for air and light. Inside, the inverted arches form an undulating ceiling over public spaces, while occasionally, interconnected floors are created at both the north and south ends of the building, creating public rooms of distinct formal qualities in the sky. 

对于该方案的开发，Hout与当地建筑师Exceptions进行了合作。
