Indoor thermal environments of Cambodian houses

Currently, there are a variety of types of house from traditional stilt houses to contemporary town houses in Cambodia. Peoples have renovated their own houses based on their own needs or wants according to economic growth. Usually, they built a shading first for cutting direct sunlight and extend their space to outside for improving the quality of life. These actions for renovating their own houses, the quality of the indoor and outdoor environment, and occupant behavior influence each other. I report here about the difference in indoor temperature between several houses include the renovated house.
