Climatic design of vernacular housing in different provinces of China.

For 2000 years, the inter-connexion between the specific structure of the Chinese eastern climates and the cultural background have produced remarkable vernacular housing types, both well adapted to the local conditions, and reflecting consistent values and knowledge. Stemming from a similar archetypal form, each house plan is translated through the specificity of the climate and resources of its site. One can think that the value and the diversity of this housing stock is due to the combination of the specific structure of the Chinese eastern climates, which creates the contrast of cold-dry winters and hot-humid summers, with the structure of the Ming t'ang, which contains the opposition of the yin and the yang. These two strong factors imprint a substantial cultural and conceptual unity upon all these housing types. Moreover, on the one hand, the geographical variations and, on the other hand, the local building materials generate a large diversity of housing types, of building techniques and of climatic devices which can be observed all around the country. These lessons could be valuable design guidelines from the past for the future.
