架构师提供的文本描述。越南的快速发展带来了许多城市问题：绿地减少、电力短缺和洪水泛滥。越来越多的摩托车造成了交通堵塞和严重的空气污染。河内一个典型的单间装修项目“绿秋装修”就是在这样的背景下设计的，它把绿色植物送回了城市，并鼓励居民和邻居都有一个舒适的居住环境。

Text description provided by the architects. Vietnam’s fast development raises many urban problems; less green space, electricity shortages and flooding. The increasing number of motorbikes are causing traffic jams and serious air pollution. “Greenfall renovation”, a prototypical single house renovation in Hanoi, was designed against this backdrop, returning greenery to the city and encouraging a comfortable living environment to both the resident and the neighbors.

位于市中心的15年老旧房屋位于西南一条街的拐角处和西北的一条小巷里，一直处于昏暗、潮湿和发霉的环境中，这是河内许多老房子的典型情况。这所房子被安全栅栏和百叶窗封锁，使阳台闲置了空间。

15-year-old existing house, located in the city center, at a corner of a street on South-west and an alley on North-west, had suffered from dim, dark, wet and moldy environment, which is a typical condition for many of the older houses in Hanoi. The house had been secured and closed by security bars and shutters, making balconies unused space.

为了解决这一问题，对房屋进行了改造，使其生活在绿色和充足的光线下，用细长的钢楼梯取代了现有的大体积混凝土楼梯，形成了一口三角形的光井，从天窗中引入自然光和通风。这种光井的墙壁是由块状大理石完成的，以反射和传播光线。另一个空隙被切割成一层板，将餐室(GF)与一项研究(1F)连接起来，该研究鼓励了居民之间的交流，并将阳光透过绿色的外墙带到屋内深处。一楼是为了在下面安装通风层，以防止上升的潮湿和凝结，这是一个经常出现的问题，在汉诺尼亚的房屋在季节交替。

To remedy this situation, the house is renovated to live with green and abundant light.  Existing massive concrete staircase was replaced with slender steel stairs, creating a triangle light well, through which natural light and ventilation are introduced from skylight. Walls of this light well are finished by lumpy marble stone to reflect and diffuse the light. Another void was cut into first floor slab to connect the dining space (GF) with a study (1F), which encourages communication of residents and brings sunlight through the green façade deep into the house. The ground floor was raised to install air ventilation layer beneath, to prevent rising damp and condensation, a frequent problem in Hanoian houses at the turn of seasons.

房子的特点是绿色立面，名为“绿色瀑布”，这是一个令人愉快的绿色瀑布，从内部和外部吸引。旧的安全栅栏被拆除，取而代之的是镀锌钢格子，连接在现有的阳台上，登山者在上面生长。因此，未使用的阳台变成了绿色的空间，保护了居民的隐私和安全。从室内，每个房间都可以欣赏到绿色的景色，并通过它获得新鲜空气。这绿色的外观不仅是为居民，也是为邻居，提供有吸引力的绿叶景观的街道。

The house is characterized by green facade named “Greenfall”, a pleasant green waterfall which attract both from interior and from exterior. Old security fences were removed and replaced with galvanized steel trellis, attached to existing balcony, on which climbers grow. So the unused balconies are transformed into space for greens, keeping the privacy and security for the residents. From the interior, every room can enjoy the view of green and get fresh air through it. This green façade is not only for residents but also for neighbors, providing attractive leafy-scape to the streets.

绿色立面和屋顶花园共同作用，以减少能源消耗：他们保护建筑物免受严酷的西方阳光。绿色的屋顶上种着许多种类的蔬菜和鲜花，还有一棵树。由于有了大量的绿色植物，居民们变得更加了解环境，并开始采取行动减少不必要的能源。

The green facade and the roof garden function together to reduce energy consumption: they protect the building from harsh West sunlight. Many kinds of vegetables and flowers are planted on the green roof, as well as a tree. Thanks to plenty of greenery, the residents became more aware of environment and started to take actions to reduce unnecessary energy.

这种绿色立面和屋顶系统是典型的，适用于热带气候的所有建筑物。它可以成为热带国家实现潜在绿色城市的种子，为其严重的城市问题提供解决方案。它可以减少洪水的风险，土壤层起到保留盆地的作用，还可以通过增加绿色植物来减少城市热岛效应，而当地的建筑则通过共享绿色景观及其食品来促进社会互动。希望这一项目将成为热带城市绿化的一个温和模式，在那里，健康的绿色家园的好处不仅可以由居住者分享，而且对城市有更广泛的积极影响。

This system of green façade and roof is prototypical and applicable to all buildings in tropical climates. It can be a seed to realize a potential Green City in tropical countries, offering solutions for their serious urban problems. It can reduce the risks of flooding, where the layer of soil function as retention basins, as well as reducing the urban heat island effect through the increase greenery, while locally the building promotes social interaction through sharing the green-scape and its food products. It is hoped that this project will be a modest model to greening tropical cities, where benefits of a healthy green home can be shared by not just the occupant but have a wider positive impact on the city.
