低碳视角下某装配式楼梯构件综合成本计算

An Example of Comprehensive Cost Calculation of a Prefabricated Stair Component from the Perspective of Low Carbon

在“双碳”政策背景下,以预制混凝土梯段板为例,应用BIM技术提供基础数据,测算了预制构件物化阶段的碳排放量及建造成本,提出了一种包含碳排放成本在内的预制构件综合成本测算方法。实证研究结果表明:预制混凝土梯段板碳排放量最大的阶段为原材料生产阶段,约占物化阶段总碳排放量的67.46%,单位体积碳排放量为846.71kg/m^(3),低碳视角下的综合成本为4277.63元/m^(3)。该方法可以在低碳发展背景下为装配式建筑在设计阶段的方案比选提供依据。

In the context of the“double carbon”policy,taking the precast concrete ladder slab as an example,the basic data provided by BIM Technology are used to calculate the carbon emission and construction cost of prefabricated components in the materialization stage.On this basis,a comprehensive cost calculation method of prefabricated components including carbon emission cost is proposed,which can provide a basis for the scheme comparison and selection of prefabricated buildings in the design stage under the background of low-carbon development.The empirical research results show that the stage with the largest carbon emission of precast concrete ladder slabs is the raw material production stage,accounting for about 67.46%of the total carbon emission in the physicochemical stage,and the carbon emission per unit volume is 846.71kg/m^(3),the comprehensive cost from the perspective of low carbon is 4277.63 yuan/m^(3).
