Optimization Methodology of ESGB on Weights, Evaluation Rating, and Calculation of Carbon Emissions

To cope with climate change, the Chinese government took the lead in advocating the aim of a Carbon peak by 2030 and carbon neutrality by 2060. In China, the total carbon emission of the whole construction process in 2020 was about 5.08 billion tons of carbon dioxide (CO2), accounting for about 50.90% of the national carbon emission. Consequently, researchers come up with a series of standard assessments for green building optimization measures. Through analysis and comparison of Leadership in Energy and Environmental Design (LEED), WELL Building Standard (WELL), Building Research Establishment Environmental Assessment Method (BREEAM), and Evaluation Standard for Green Building (ESGB) standards, this study will draw conclusions on optimizing ESGB in terms of weighting, evaluation rating, and carbon emission calculations.
