Week 10.1 - Green buildings in Vietnam

Stacking Green 





Urbanization leads to excessive population growth and also leads to a decline in quality of life and loss of greening. “Stacking Green” is a private residential project built in Ho Chi Minh City, Vietnam in 2011, which opens up the possibility of changing this situation. The citizens of Ho Chi Minh City love the streets and are full of tropical plants and flowers, so in this project, the designers operate horizontally arranged to plant troughs to form the facade of the building. The green building facade not only provides residents with a comfortable visual experience, the natural wind is introduced into the building as much as possible to improve the indoor thermal environment, and also enhances the biodiversity of the surrounding environment. The green façade and roof garden protect the occupants from direct sunlight, street noise, and pollution. In tropical climates, the natural ventilation of the building is particularly important. Good natural ventilation reduces energy consumption and creates a comfortable indoor environment. One year after the home was built, the indoor natural ventilation was monitored to assess the effectiveness of the building design. The monitoring results show that the interior of the house forms a comfortable wind. This is also confirmed by the behavior of residential users because even in tropical climates, users rarely turn on air conditioning.
Tips: Vietnam is a tropical country, and the average temperature in Ho Chi Minh City is as high as 28 C° ! ! !


Wind and Water Cafe Bar




Cafe Bar is situated in the lush tropical forests of Ho Chi Minh City and built around an artificial lake. The building structure consists of thousands of bamboo components and the use of steel components is minimized. After traditional processing such as impregnation and smoking, bamboo exhibits the aesthetics, durability, ecology and low cost of building materials. Compared with other tropical forests, bamboo has shown superiority in absorbing CO2 and bamboo forest regeneration ability. Therefore, bamboo is not only traditional building material in Vietnam but also a green building material in the 21st century. Bamboo can not only be used as a decorative material but also plays an important role as a main structural material. The roof of the building consists of tensile members such as bamboo and steel, forming an open column-free space up to 12m wide. The V-shaped roof plane is generated based on computational fluid dynamics analysis, with the aim of introducing natural wind into the building as much as possible.

The design team analyzed the building's natural lighting, energy, and indoor climate while determining the shape and orientation of the building based on where the sun moved, ensuring maximum use of daylight and solar energy. In order to achieve a seamless transition between the various functional areas and indoors and outdoors, the site selection and construction of the building are as natural as possible. As can be seen from the images, the entire kindergarten's functional area includes large and small event areas, public event rooms and restaurants, and the outdoor area is furnish...
