| Abstract | Taking a small house as an example, the thermal performance and carbon emission of straw as building material in severe cold areas of China are examined in this paper. The house takes wood as the structural system and straw as the outer enclosure system. Through the thermal performance calculation, it is found that the heat transfer coefficient of the residential straw wall is lower than the external wall heat transfer coefficient standard in the severe cold area of Hebei Province, and can meet the requirements without using additional thermal insulation materials. This paper also calculates the carbon emission of straw 3000 * 3000mm unit wall in the production stage, and compares it with thatofhollowclaybrick,autoclaved aerated concrete blocksandgangueshale hollow brick wall. It is found that the carbon emission per unit straw wall is 18% less than that of hollow clay brick and 60% less than that of autoclaved aerated concrete blocks. Without considering the carbon sink, the carbon emission per unit straw wall is slightly higher than that of gangue shale hollow brick-wall. |
