Farming KinderGarten


Bien Hoa City, Dong Nai Province, Vietnam

Type of Building: Education Building
New / Refurbished: New
Status: Operational Stage
Year of construction: 0
Gross Floor Area: 3800 sq.m

Situated in Bien Hoa City, Dong Nai Province, Farming Kindergarten, a kindergarten designed for 500 pre-school children with 10,650m2 site areas, 3,800m2 GFA and a continuous green roof was honorably awarded in the Asia’s Leading Green Design Competition, called FuturArc Prize. The building design is a prototype for sustainable education spaces in which children can learn how to grow their own food.

Passive Design

Buidling Orientation and Shading:
Located in a planning area of Vietnam Pou Chen Group, Farming Kindergarten has the main Northeastern direction which is adjacent to the main road. The Western and Southern directions of the project are adjacent to sport center and Pou Chen’s worker buildings. The design strategy is to create shadings by making use of not only building shape (due to the fact that the building was built on a vacant land and higher than other surrounding buildings) but also green floral systems.

To use the buildingitself forshading, the building shape is taken into consideration with the triple-ring-shape green roof drawn with a single stroke.

A continuous green roof was constructed at the top of the building, loops around to frame the outline of three internal courtyard playgrounds. The classrooms inside the building will follow the same loop of the green roof. The concrete louvre system was designed to help shading the windows and relief from intense sunlight in summer.

Natural Ventilation:
The natural ventilation of the building is based on three main factors: building shape orseparated spaces, louvre systems and green roof. The design strategy aims to take advantage of natural ventilation and reduce mechanical (forced) ventilation for energy savings. The minimum depth of each room is 8m-10m with two elevations. The AC system and forced ventilation principle are not applied in all classrooms and nursery rooms.

In terns of building shape, as mentioned above, the green roof was drawn with a single stroke that create three separate courtyards inside the building. In addition, the lourve system to relief intense sunlight and take in natural wind was designed at both sides with the width of up to 2,5m. Finally, the continuous green roof is aimed at cooling the building and reducing CO2 emission.

These threekey factors, especially building shape, form a comfortable microclimate environment for the whole kindergarten thanks to perfect natural ventilation and natural lighting.

Natural lighting:
The daylighting strategy mainly focuses on the semi-outdoor corridor and lourve systems which designed following the same loop of the green roof in orderto reduce directly exposed to the intense sunlight of the building. Bothaim not only to prevent direct sunlight but also to ensure unobstructed views and  the connection between interior and exterior spaces.

Each of the louvres is 50x1200mm long, made from pre-casted concrete and was installed separately with the span between each of them is 250mm. Most of the louvre is placed on the second floor and other frontages that are maximumlly exposed, mainly in the West and East direction.

Internal Green Space:
One of the most special features of Farming Kindergarten is the continuous green roof. This roof slopes up from the ground and peaks at two storeys. The main purpose is aiming to maintain the temperature inside the building and provides safety and comfortable playgrounds for children. The green roof design allows children to enter a very special eco-friendly experience when they walk up and go through the garden. Also, it functions as a place to teach children the importnace of agriculture and relationship with nature.

Active Design

Architectual and mechanical energy-saving methods are comprehensively applied but unlimited: including green roof, concrete lourve system, precast concrete lourve system, recycle materials, solar hot water and so on. These devices are designed visibly for children and play an importnat role in sustainable education. Additionally, Farming Kindergarten is designed to maximize the natural ventilation via a computational fluid dynamics analysis.

The solar power performance of the building creates several differences to achieve the following goals:

  • Reducing the monthly energy consumption.
  • Using an independent electricity resource.
  • Protecting environment
  • Preventing eletrical overloads
  • Having a continuous power source, even when a problem occursto the local eletricity distribution network.
