竹结构住宅全生命周期碳排放分析OA北大核心CSTPCD

To well understand the carbon emission of bamboo houses,this paper presents a life-cycle carbon emission assessment on a two-story bamboo house built at Nanjing Forestry University.Emission-reduction strategies for different carbon emission phases were proposed.Moreover,the differences in carbon emission from typical bamboo,timber,and steel houses with identical dimensions were compared.The results showed that the operation phases emitted the most carbon in the life cycle of the bamboo house,accounting for 89.8%of the total.The carbon storage in the engineered bamboo products accounted for 8.8%of the total carbon emission.Bamboo and timber houses with various structural systems exhibited similar net carbon emissions in their life cycles.Due to high energy consumption and low efficiency in thermal insulation of steel,the carbon emissions of steel structures are 89.9%higher than the average carbon emissions of three types of bamboo or wood structures.
