Optimisation Method for University Gymnasium Envelopes in Cold Regions Based on Life Cycle Carbon Emission Calculation
摘要
Abstract
Under the background of building a leading sports nation and achieving the dual carbon goals,the contradiction between the severe carbon emission intensity of gymnasiums and the precise quantification of life cycle carbon emissions has become increasingly prominent.This study addresses this challenge by establishing a multi-objective optimisation framework for stadium envelope design,integrating life cycle carbon emissions,cost,and peak load as optimisation objectives.Based on the SPEA-Ⅱ algorithm,a computational model is developed,and a CEPI is proposed to evaluate the optimisation effectiveness.Taking typical university gymnasiums in cold regions as case studies,including those at Harbin Institute of Technology,Shenyang Aerospace University,and Dalian University of Technology,this research conducted empirical analyses on life cycle carbon emissions and multi-objective optimisation by considering insulation material types,insulation thickness,and window-to-wall ratio as variables.Compared with existing solutions,the comprehensive optimisation results demonstrated reductions in life cycle carbon emissions by 2.5％,2.2％,and 7.1％respectively for the three gymnasiums.Concurrently,life cycle costs decreased by 3.5％,8.9％,and 8.6％,while peak loads were reduced by 7.5％,8.4％,and 8.9％correspondingly.Based on these findings,targeted optimisation design strategies were proposed,providing both theoretical foundations and practical guidance for the envelope design of university gymnasiums in cold regions.关键词
