Abstract

Building ventilation is very important to supply fresh air and removing indoor pollution concentration. Due to the increasing cost of energy sources nowadays, people are seriously looking into possibilities of relying on natural ventilation to achieve comfort. Based on the understanding of how natural ventilation works, this study proposes a design approach implemented on a real building in providing good indoor air movement. Taking all site contexts as the basis of design, Kebun Angin, a single unit house is designed to be able to enhance the indoor ventilation performance. The house is designed with high atrium that acts as the stack throat to move the air vertically inside the building. Meanwhile, proper size and location of ventilation openings are also provided to catch the cross ventilation for horizontal air movement without interrupting the stack ventilation process. By keeping the neutral plane low, an isothermal jet may also developed at the upper air intake that may push the air further inside the building. Proper building insulation is also important in order to keep the air pressure difference to move the air around. Meanwhile, shading devices are essential to all the openings. The device may create shaded area in front of the openings which may act as the ‗cooling buffer‘ for the air before moving into the building
