Research On Cost Management Of Prefabricated Buildings Under Double Carbon Background

Environmental degradation and energy shortages have captured the attention of nations all over the world recently,and the idea of low-carbon emissions and environmental protection has gained popularity.2020 "double carbon" objective proposed by China.Due to its continually increasing energy consumption,the construction industry,one of the foundations of the national economy,has a vital role to play in energy conservation and emission reduction.As a new construction method in the process of industrialisation of construction,green environmental preservation and low-carbon energy savings are possible with prefabricated building.,and has become a new trend of progress in the construction industry at this stage.Domestic provinces and municipalities are clarifying the proportion of prefabricated floor space and continuously improving the supporting policies for prefabricated buildings,which have played a positive role in promoting the development of prefabricated buildings,and the systematic recognition and effective control of prefabricated building costs are gradually becoming a new concern.Therefore,the study of cost management of prefabricated buildings in the context of double carbon has important research value.In this paper,the research on cost management of prefabricated buildings in the context of double carbon was conducted.26 influencing factors were initially identified through reading and summarising the literature,and the original data on the importance of the influencing factors were obtained by means of a questionnaire survey,and 12 key influencing factors were finally identified by means of the software SPSS on the basis of a comprehensive consideration of the importance of the influencing factors.The DEMATEL-ISM model was used to analyse the importance and correlation of the key influencing factors,calculate the internal relationships between the factors and their influence paths,as well as the hierarchical relationships between the factors.The four tiers are categorised as direct,indirect and fundamental factors.The direct factor is the first tier and contains the material price of the components,the production capacity of the component factory,the distance and efficiency of the components,and the efficiency of the construction personnel.The indirect factors are the second and third levels.The second level contains the design index of new energy-saving materials and the professionalism of site managers;the third level contains feasibility studies,the professionalism of designers,and the prefabrication and assembly rates.The fundamental factor is the fourth level,which contains incentive policies and regulations,integration of design systems,and deepening design of component splitting.This book provides a theoretical reference for the construction of a cost management and optimisation system for prefabricated buildings in the context of double carbon,and provides practical guidance for prefabricated buildings to help achieve the goal of "double carbon".Figure[9] Table[18] Reference[43]...
