This thesis contains five chapters. Chapter 1 introduces the cause, purpose and value of the thesis and the problems that affect the existence of the east-and-west-facing residence. Chapter 2 analyzes the affecting factors of the facing of residence including the thermo-comfortability, the spiritual and mental state and the ecological environment etc. Chapter 3 analyzes the specific circumstances, under which the east-and-west-facing residence is practicable. For example, in order to enjoy the view, to make good use of the land and to form the endocentric residential area, we can choose the east-and-west-facing residence. Chapter 4 puts forward some measurements, including the planning design, the architecture design and the constitution design, to make the east-and-west-facing residence hot-proof so that we can eliminate the most disadvantageous factor in the south. Chapter 5 gives some examples of the east-and-west-facing residence in the south.
