Zoka Zola’s Naturally Cooled Bamboo Hostel is a Giant Wind Scoop

The hostel will be a corporate retreat and training center but the developer also wants to push the limits of green design. The 24 bedrooms are all set on an upper floor which is fed fresh air by an aggressive wind scoop system built into the roof. Designed in conjunction with Arup Engineering , the roof directs the prevailing winds and pushes them into the core of the building, providing each room with cooling breezes. The lower floor will be the community area with a restaurant, conference space and indoor/outdoor area tucked below the sleeping quarters.
Humans are kept comfortable not only by cooled air but by moving air  which draws heat off our skin. In fact natural breezes provide comfort in rooms that are much warmer than typically tolerated.
By carefully incorporating the natural wind patterns of the site the building is designed to accommodate the changing wind conditions. The aggressive flared roofline on either side of the building efficiently captures the moving air– which is then transferred throughout the second floor using large plenums. The air exits out again through an open grid floor to the open space below. During the day southerly breezes come from the ocean and in the evening cool northerly winds come down the forested slope and wash across the building. The roof also acts as a buffer from solar gain . Sunlight will be carefully controlled to bring in diffused lighting while avoiding direct solar heat.
The building is made mostly from bamboo, an indigenous grass to Southern China and a excellent building material. The copious use of the traditional building material is intended to help bring bamboo back as a contemporary choice in low rise buildings. Furniture and finishes will also be made from the versatile grass.
