Abstract This paper takes the modern commercial street in Nanshan District of Shenzhen City, Xili commercial street and Pingshan commercial street in the city village as the research objects. According to the calculation and comparison of the total life cycle of buildings, the construction waste and carbon emissions generated in the process of shop replacement along the street are compared. From the perspective of architectural adaptability design, the following conclusions are drawn. In the process of shop replacement along the street, the differences between shop floor area and store replacement type are the main factors affecting carbon emissions. Smaller shops are conducive to the same type of shop replacement , so as to reduce the amount of construction waste generated by demolition and decoration , and then reduce the amount of construction carbon emissions to protect the ecological environment. The conclusion of this study gives some guidance to the renovation, planning, design and management of stores along the street.

2014年以来, 全国多地出现“关店退租”现象。2017—2019 年, 全国有近80%的书店关门, 近 30%的服装店和鞋店关闭[1]。关闭的店铺一部分经重新装潢, 改造成新的店铺, 在此过程中产生了大量的工程垃圾。与此同时, 尽管近年来大型商业综合体的兴起使得实体经济消费有所复苏, 但也加剧了传统商业街道的生存难度[2], 导致其店铺关闭转让的

频率加快, 产生更多的建筑垃圾, 其中很大一部分被掩埋, 对生态环境造成危害, 估计我国每年的建造和拆除垃圾量在2020年达到20~30亿 t[3–6]。另有研究者指出, 在建筑建造和改造拆除产生的垃圾中,

[7–8]约70%来自建筑拆除废物 。这些数据表明, 我国建筑改造垃圾产生大量碳排放量, 问题的严重性不容忽视。同时, 随着大规模的城市改造, 由建筑
