The livin8 environment in this region is extremely poor because of the harsh climate and the backward economy. The external wall is an important component of the external envelope of buildings, and it greatly contributes to the indoor thermal environment. By taking the external wall as the research object, this study summarizes the characteristics of the external wall structure and analyzes the common materials used in existing rural residences. Specifically, we combine life cycle theory and ecological footprint （EF） theory and introduce the green external wall structure, as well as its application in practice, in accordance with the local ecosystem. Results show that anecotosical residence offers a better environment and greater economic benefits than a traditional residence. The annual energy consumption, C02 consumption, and EF of the ecological residence in this study are lower than those of the traditional residence by 69.61%, 17.5 t, and 99.47%, respectively.展开更多
