在今天的越南河内，人们倾向于在家里创造小地标，包括放置鱼塘，这可能是小型水族馆或投资较高的锦鲤池。此外，城市中蔬菜污染的情况也导致在居民家中直接种植新鲜蔬菜的愿望变得势在必行。现在，许多家庭在家里组织种植蔬菜，但大多是采用自发的方法，没有战略计划或建筑美学。这些是蔬菜泡沫箱，放置在房子的狭窄空间里，或放在阳台和顶部露台的花园区域。

In present-day Hanoi, Vietnam, people tend to create small landmarks in their homes, including the placement of fish ponds, which may be small aquariums or Koi ponds with higher investment. In addition, the situation of vegetable contaminants in the city also causes the desire to plant fresh vegetables right in resident homes became imperative. Nowadays, many families organize planting vegetable at home, however, mostly following spontaneous methods, without a strategic planning or architectural aesthetics. These are vegetable foam boxes that are placed in a narrow space in the house, or in the garden area of the balcony and top terrace.

Farming Architects提出的城市VAC模式
Farming Architects正在重新设计VAC系统，以便在城市地区实施。其目的不仅是产生对自然资源的有效利用，而且还喜欢在城市环境中使用不同类型的植物和动物进行实验。

Urban VAC model proposed by Farming Architects
Farming Architects is re-designing the VAC system to be implemented in an urban area. The aim is not only to produce an effective use of natural resources but also favorite experimentation in using different types of plants and animals in the urban environment.

VAC-图书馆是如何工作的？
VAC设计的核心特点是鱼菜共生，它是一个将传统的水产养殖（饲养水生动物）和水培（在水中栽培植物）结合在一起的共生环境。鱼菜共生利用鱼塘的循环水为植物提供营养。亚硝酸盐/亚硝酸盐细菌会把鱼缸里的废物转移到适合植物的富含营养的作物中。水也被植物净化并供应给水族箱。该系统的设计考虑到了节能，使用可再生能源（通过转移太阳能），并尽可能让水自然向下流动，以减少水泵的数量。此外，还提供照明和泵的电力–从屋顶的太阳能电池板上节省下来。

How does VAC-Library work?
The core feature for the design of VAC is the Aquaponics, it is a system that combines conventional aquaculture (raising aquatic animals) with hydroponics (cultivating plants in water) in a symbiotic environment. Aquaponics uses circulating water from a fish pond to provide nutrients to plants. Nitrite/nitrite bacterium will transfer the waste from the aquarium into a suitable nutrient-rich crop for plants. Water is also purified by plants and supplied to the aquarium. The system is designed with energy conservation in mind, using renewable energy (by transferring solar energy) and a reduced number of pumps by letting the water flow downwards naturally as much as possible. Besides, electricity for lighting and pumps are also provided – saved from solar panels on the roof.

结构语言
VAC图书馆使用的语言来自于木质框架的使用。这种技术形式有助于创造一个灵活和可适应的结构。 这也作为一种空间组织，划分为不同的功能区。VAC图书馆还面向儿童的开放式图书馆空间。该地区和其他地方的儿童可以来这里一起玩耍，阅读书籍，并在建筑中直观地了解这种生态模式。孩子们会知道，锦鲤鱼不仅是可以观赏的宠物，还知道它们的排泄物会如何被带到蔬菜种植槽上，水是如何供应给蔬菜，然后过滤回池塘的。旁边的笼子里养的鸡会下蛋，供人食用，它们的排泄物也对园艺有益。

Structural language
VAC Library uses a language deriving from the use of wooden frames. This technical form helps to create a flexible and adaptable structure. This also works as a spatial organization, division to be different functional areas. The VAC Library is also geared towards an open library space for children. Children in the area and elsewhere can come here to play together, read books, and learn about this ecological model visually at the building. The children will know that Koi fish is not only pets to watch, but also know how their waste will be carried on the vegetable planters, how the water is supplied to the vegetables and then filtered back to the pond. The chickens which are raised in that cage beside will lay eggs and serve for meals, their excrement is also good for gardening.
