Building "short-lived" phenomenon is very common in China. It is extremely wasteful for a developing country with limited resources and financial resources (per capita). Any green low carbon, energy saving and environmental protection without building safety would like water without a source, and a tree without roots. Extending the building life, based on Chinese current situation, mainly starts out here from two aspects of new buildings and the existing buildings, and need strengthen government regulation. Fundamentally extend building life and promote building energy efficiency.

According to engineering fuzzy set theory and system coordination degree model proposed by professor Chen Shouyu and Yu Xuefeng, this paper established social economy-ecological environment-water resources comprehensive evaluation index system, combined with social and economic development situation, ecological environment and water resources utilization status in 9 areas of Jilin province, 2011. The paper made an evaluation of the existing water resources coordinated development of Jilin province, and analyses relative coordinated development level among regions.

Combined with the local climate characteristics, peasants existing living conditions and economic development level in the mountains of eastern Jilin, the paper analyzed with energy conservation transformation method of the existing grange and expounded the operative technology of energy conservation transformation of auld grange from the point of envelop enclosure, heating system and renewable energy resource, which is now suitable for the new grange in the mountains of eastern Jilin.

Combined with climatic feature and peasants economic condition in existence,starting with engery conservation design of grange and analysis of reconstruction technology,the writer briefly expound the operative technology of engery consevation and the reconstruction technology of auld grange,from the point of envelop enclosure,heating system and new energy resource,which is now suitable for the new grange in the Jilin province.
