Energy efficiency research of straw brick wall in rural house in cold areas of China

In cold areas, the amount of heating energy is closely related to the envelop enclosure of house. Among the envelop enclosure, the wall is the main way of heat loss, accounting to about 50% of the total. Based on the investigation of the straw brick houses in cold rural areas, this paper compared the energy consumption of straw brick wall with that of the traditional clan brick wall and EPS complex wall oriented to all life cycle. Meanwhile, with the energy simulation software-Dest simulating the heating energy consumption in the using stage of houses, the result was that straw brick house can save over 50% energy compared to the traditional clan brick house. So it can be concluded that the straw brick wall is not only suited to the environmental protection, but also energy efficient and economical, adapt to be spread in cold rural areas in China.
