The roof of traditional Malay houses are designed to provide shade and protection from heat and rain, as well as to provide ventilation. At this building, the type of roof is Bumbung Panjang, which is large, dominates the low walls and the open stilted bottom of the house.
The juxtaposition of the roofs with different sizes and at different orientations creates an interesting visual form.
Roof 2 usually built above the‘middle house' which also consist of the attic, two levels/ storey space
the degree of roof 1 is 30°，roof 2 is 45°
Because the building is too high that can not take the detail dimension so I foundthe proportionate rules of this building: the proportion of stilts and walls height of the houses is equivalent as a proportion of X,while the roof height measured from the roof eaves to the ridge is a proportion of 2X.
The main material is timber and palm leaves .It does not retain heat and cools immediately, because the building in Malay need a low thermal capacity to keep interior cool.
The other climatic responsive design is roof gable. In the roof 1 gable, it have a small opening, in the roof 2 gable, it have some ventilation panels.
the section of roof gable 2 is like that
The roof purlin in here is not really fix on the top or rafter, it is just have a balance and support the rafter and cover By this kind of design, it is allow air to flow into the roof space and cool the house, maintain good ventilation and make people's lives more comfortable.
