On the May 12, a huge earthquake occurred in Sichuan Province, and causing tremendous damage. There are 5,401,900 housing collapsed and 5,932,500 severely damaged, and the large number of them should be reconstructed urgently. In the planning and redevelopment of housing for rural residents amounted to 3,500,000 units only in Sichuan. The surveying of post-disaster reconstruction by writer indicating, the buildings of residential in Earthquake-stricken villages and towns are constructed in lower standard than those in city. Single-layer and two-story stand-alone home is the main type of the rural traditional housing. The existing housing in rural areas did not take energy-saving into account, and the vast majority of them cannot meet the minimum level of energy-saving. There will be a good opportunity to promote the energy-saving technique in post-disaster reconstruction in rural areas. Based on the command of building energy-saving design, and combined with climate and geographical characteristics in Wenchuan quake-stricken, the outer blinds system proposed in the energy-saving design of the rural residential post-disaster reconstruction. The outer blinds system is one of traditional architecture techniques. The adjustable sun visor can all be found in the Ming and Qing Imperial Palace and the receiving chamber. But at present, the outer blinds system can be little taken into account in the buildings by local architects and designers. The paper based on energy-saving effect, shade materials, and the service life and initial investment; explored the applicability of outer blinds system in rural areas post-disaster housing construction, and put forward solutions and technology roadmap. The results showed that the shade outside technique has such characteristics like low cost, effective and simple. There are strong applicability in the rural residential post-disaster reconstruction. The paper also analyzed the shade outside technical problems in order to provide some references in post-disaster reconstruction.
