As one of the important parts in the architecture design, ventilation fully reflects one important factor of energy conservation to some extent. To ensure that decreasing use of energy resources to the maximum extent in architectures and make architectures harmonize with their surroundings, which have become important pursuing gradually for residential architecture, at present, integrated design of residential architecture should not only highlight natural ventilation technique, but also should integrate natural ventilation and main feature of local climate, etc. What's more, designers shall carry out unified analysis on the base of taking all factors into consideration. This point is more important. By this way, architecture technique can be more comprehensive and complete. With the guidance of sustainable development concept, natural ventilation as one of ecological technologies is applied extensively in many architecture designs owing to its economic effect and health benefit.
