摘要

为分析河北雄安新区白洋淀码头的3栋木混结构建筑较等效钢混结构建筑的减碳效果，根据等效替换因子，确定等效钢混结构建筑建材用量，并依照GB/T 51366—2019《建筑碳排放计算标准》，基于全生命周期评价法，对3栋木混结构建筑及等效钢混结构建筑进行碳排放计算。结果表明，木混结构建筑的减碳效果主要体现在建材生产及运输阶段，建造及拆除阶段碳排放差异较小。与等效钢混结构建筑相比，木混结构建筑在建材生产阶段的碳排放下降约10%，考虑木材碳固存量则下降约19%。木混结构建筑地上部分建材生产阶段的碳排放下降18%~25%，考虑木材碳固存量则下降40%~46%。

Abstract

In order to study the effect of three timber-concrete constructions on the carbon reduction in Baiyangdian Wharf of Xiong'an new area in Hebei Province, it was compared with the equivalent steel-concrete constructions. In this paper, according to the equivalent replacement factor, the amount of building materials of equivalent steel-concrete constructions was determined. In accordance with GB/T 51366—2019 ,Standard for building carbon emission calculation, the carbon emission of three timber-concrete constructions and equivalent steel-concrete constructions were calculated by using the life-cycle assessment method. The results showed that the carbon reduction effect of timber-concrete constructions was mostly reflected in building material production and transportation period, and the carbon emission difference in construction and demolition period was relatively small. Compared with equivalent steel-concrete constructions, the carbon emission of timber-concrete constructions decreased about 10% in material production period, and about 19% in terms of carbon sequestration of wood. Carbon emission of the above-ground timber-concrete constructions decreased about 18%~25% in material production period, and about 40%~46% after considering carbon sequestration.
