Comprehensive Evaluation of Carbon Emissions from Residential Buildings in Jiangsu Province's Prefectural-level Cities Based on the Entropy Weight-TOPSIS Method

Abstract

This study aims to conduct a comprehensive evaluation of building carbon emissions based on the Entropy Weight-TOPSIS method. The construction industry is one of the primary sources of global greenhouse gas emissions, so evaluating the level of building carbon emissions is crucial for promoting sustainable development. The Entropy Weight-TOPSIS method combines the entropy weight method and the Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS), allowing for a comprehensive assessment of building carbon emission performance considering multiple indicators. This research first identified a series of initial key indicators affecting building carbon emissions, then used the Delphi method to screen and finalize these indicators. Finally, the Entropy Weight-TOPSIS method was applied to rank and evaluate the carbon emission performance of different buildings. The research results can provide decision support for the construction industry to reduce carbon emissions and promote sustainable building development.
