2.4 Sustainable Design Our design of the women’s house is concentrated on sustainability by the use of natural resources effectively. Based on the fact that using power is not a cost-efficiency solution to lighting and cooling in rural areas, passive design will be the main system for the buildings. Moreover, to facilitate the self-build and reduce the pollution from construction, we will use the natural materials that are easy to access, manufacture and build as much as possible. ● Passive Design The inclined and overhead roof allows natural light to come into the house during daytime that minimize the use of artificial lighting (Figure 2-19). The windows and the roof work together to provide natural ventilation and natural lighting to the rooms. It also allows cool wind to come in and bring heat outside the building (Figure 2-18).l If it is during hot seasons, the window can be closed to reduce the heat light coming in, otherwise, it will be opened for ventilation and cooling. This will minimize the power required during daylight and hot summer time.
