jismart2024051: Analyzing the Generation of Renovation and Demolition Waste and Its Influencing Factors in Existing Residences: A Case Study of Shenzhen

Abstract

With the expansion of the existing building market and the increase in renovation activities for existing residential properties, the impact of renovation waste from these properties on resource sustainability is expected to grow significantly. Current research provides limited attention to the renovation waste of existing residential buildings, posing substantial challenges to advancing sustainable resource utilization. This study investigates the waste generated across various renovation scenarios in existing residential buildings. Through a questionnaire survey, household renovation data were collected, and the K-means clustering algorithm was employed to categorize renovation scenarios into three distinct types. Further, a logistic regression model was applied to analyze the impact of five renovation factors on the volume of waste generated in existing residences. The findings reveal a significant positive correlation between renovation waste generation and personal preferences and increased demands from household members. Additionally, household income was found to have a notable influence on generating renovation waste in existing residences. This research provides a novel perspective for analyzing the volume and influencing factors of renovation waste in existing residential buildings, supporting sustainable urban development.
