The annual dynamic energy consumption of addition solar house and the annual solar energy of exterior-protected construction of passive solar house with additional sunshine room in Tianjin rural areas were calculated by the numerical simulation. The annual exterior-protected construction of that residence has been analyzed also which include the number of before used additional sunshine room and after used it. Meanwhile the annual dynamic energy consumption of the wall with thermal materials and the sunshine room with LOW-E glass are imitated by numerical simulation. The numerical values are compared and analyzed with those of the walls without using thermal materials and LOW-E glasses. Analysis results show that the energy consumption of additional sunshine room with LOW-E glass reduces by 80%, and that of the exterior-protected construction with thermal material reduces by 43.5%. Through the comparison analysis of economic benefit, the investment of thermal materials and LOW-E glass is about 97396 Yuan, the cost of which can be recovered within 5 years.
