摘要

为了深入了解竹结构住宅的碳排放特性，基于全生命周期方法评价南京林业大学校园内一栋2层示范性竹结构住宅的碳排放量，提出相应的降碳策略，对比分析相同体量木结构（轻型木结构、胶合木结构）和钢结构住宅的碳排放差异。结果表明，竹结构住宅在运行阶段的碳排放量最多，约占其全生命周期碳排放总量的89.8%，竹材自身碳储量占建筑碳排放总量的8.8%。不同结构体系的竹木结构住宅全生命周期净碳排放量相差不大，而相同体量的钢结构住宅则因建材生产能耗高、保温隔热性能差的劣势，其碳排放量比3种竹木结构住宅碳排放量平均值高约89.9%。

Abstract

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.
