"In Vietnam we have problems with energy"
- Vo Trong Nghia on Stacking Green

| 4 comments

World Architecture Festival: in this movie we filmed, architect Vo Trong Nghia explains how the house he designed with a vertical garden on its facade incorporates natural daylighting and ventilation systems that are invaluable in Vietnam, which experiences heavy rain and high temperatures, but often suffers day-long power shortages.

Named Stacking Green, the building won the award in the house category at the World Architecture Festival in Singapore earlier this month and is located in Ho Chi Minh City.

"In Vietnam we have many problems with energy and electricity, it can stop many times a day," Nghia tells Dezeen editor-in-chief Marcus Fairs. During these times light is able to filter into the house through the inner wall of glazing, but the twelve layers of plants in front prevent direct sunlight from passing through and increasing the internal temperature.

Natural ventilation also comes through this planted facade. "To invite wind into the house you open a window and then the air goes through the vertical garden," he says. "Even when it is raining you can open the windows."

Nghia also discusses how Vietnam is "developing so quick," but shouldn't fall into the easy trap of following the architectural styles of western countries. "The climate is totally different, yet we almost do the same thing," he says, before explaining why he designed this house for the continuous "hot summer" rather than for the changing seasons of Europe.

    Beautiful design. Must be nearly as nice to live next to as it is to live in.

    Nice work. By the photos its not clear how do they access the green trays to maintain the plants, any ideas?

      You can just reach up and water them from the decks on each floor. I asked them about this (but not in the interview) and they explained that you can do it pretty easily as you can access the area between the planters and the glass. You may need to stand on a chair or something for the higher planters I imagine.
