RESEARCH ON LCA ENVIRONMENTAL IMPACT EVALUATION OF PUBLIC BUILDINGS IN SEVERE COLD REGIONS
In civil buildings,due to the building standards of public buildings and the particularity of service func-tions,the degree of environmental impact of public buildings is significantly higher than that of residential buildings.We use the eFootprint software platform to carry out the whole life cycle environmental impact assessment of a pub-lic building in a severe cold area,and through the analysis of the LCA results of public buildings,the contribution rate of each stage of the building to the nine major indicators is clarified.The impact contribution of each part of pub-lic buildings to environmental indicators can be compared,and data support can be provided for the subsequent for-mulation of emission reduction strategies.
