Comprehensive Evaluation of Carbon Emissions from Residential Buildings Based on the TOPSIS Method

Carbon emission reduction is a challenge and an opportunity for all countries in the world. In this paper, Delphi method applied to screen indicators affecting carbon emission, first second level weighting are derived according Spearman, heat map, entropy method, building life cycle indicator system established. Then, taking Jiangsu Province as example, TOPSIS was used comprehensively evaluate of buildings prefecture-level cities Province, concluded that Suzhou City residence most reasonable ideal compared with other regions ten, verified reliability model. Finally, paper based on construction LSTM, linear regression, LGBM, decision tree, etc. emissions guessing model, after comparison, LSTM model performance more excellent, so we chose measurement, 2023, expected be 127,902,900 tons.
