Abstract The challenge in Net-Zero Energy Building (NZEB) retrofitting is to identify the most effective measures address energy performance issues. This paper presents a machine learning model for optimizing retrofit achieve NZEB under influence of climate change. Specifically, non-dominated sorting genetic algorithm (NSGA-III) minimizes consumption and predicted percentage dissatisfaction (PPD) while achieving NZE balance, thereby obtaining Pareto front. Order Preference by Similarity Ideal Solution (TOPSIS) ranking technique then applied front obtain an optimal solution. Various passive are investigated, renewable employed cover required energy. process repeated different time frames consider impact change on selecting measures. results clearly indicate that, residential NZEB, higher insulation values needed future scenarios compared present scenario due effects Using defined Shared Socioeconomic Pathways framework, level envelope Sustainable Future Fossil Fuel-dependent scenario, with increases 35% 50%, respectively.

Issues of energy efficiency and sustainability in buildings are gaining increasing attention the context “3060” dual-carbon initiative. In recent years, nearly zero-energy (nZEBs) have emerged as a potentially viable solution to challenges crisis building sector, it is important study factors influencing their consumption carbon emissions. However, existing research lacks analyses multifactor interactions, problem high has not been sufficiently addressed. Taking typical residential Yangtze River basin subject, this study, jointly funded by University Nottingham Hubei Technology, proposes hybrid approach that combines simulation orthogonal experiments investigate pertaining buildings, people, environment identify key explore emission characteristics hot summer cold winter (HSCW) zones. Our findings reveal following: (1) The use renewable sources, such solar photovoltaic power generation water, systems ground-source heat pumps, operation phase baseline can result 61.76% energy-saving 71% utilization rate. (2) To more easily meet requirements nZEB standards, recommended keep KE within range 0.20–0.30 W/(m2·K), KR 0.15–0.20 VT 0.6–0.7 h−1. This will help critical affecting provide valuable reference for HSCW
