Study On Network Interactivity Of Green Building Engineering Community

Greening and carbon reduction in building engineering are important elements of the sustainable development of the global construction industry,and the engineering community has an important and innovative role to play in this developmental process.China has made substantial achievements in theoretical research,technology innovation,and engineering practices in green building.However,there is relatively weak parallel development of green new construction engineering and green retrofitting engineering in China.The cooperative mechanism of the entire green building industry chain and the innovative application system of green building technology restricts the sustainable development of green building in this country.The Green Building Engineering(GBE)has characteristics,such as social cooperation and participation,the distribution and sharing of benefits,and the integration and innovation of technology,that implement the requirements of multi-attribute interaction and optimization.The engineering community is a collection of stakeholders who undertake construction services for modern building engineering,and the establishment and optimization of the Green Building Engineering Community(GBEC)is an urgent requirement to achieve improved construction efficiency and the high-quality development of the GBE.With the guidance of promoting high-quality development of the GBE,this thesis aims to establish and optimize the GBEC by focusing on a network interactivity analysis of the GBEC.The establishment method of the GBEC was proposed.The network interaction mechanism of the GBEC was explored,and a network interactivity identification model and the network interactivity evaluation method of the GBEC were established.This thesis provides a new perspective and path for the theoretical research and practice of green building and the engineering community.The primary research content and results are as follows:(1)The establishment and application method of the GBEC were proposed.The development and evolution of the building engineering community were analyzed,and a method of establishing the GBEC based on the characteristics of the GBE was proposed.This process included steps,such as the identification of engineering stakeholders,analysis of the functions of community members,and a definition of the community constituents.The objective existence and replicability of the GBEC were illustrated through an analysis of typical examples.(2)The network and interaction mechanism of the GBEC were explored.The multilayer network relationships of the GBE and the multiplex network translations of the GBEC were analyzed,and a translation establishment method of the Network of GBEC(N-GBEC)was proposed based on the Actor-Network Theory(ANT).The network interaction mechanism of the GBEC was explored,including two types and three ways of single-layer network interaction and two-layer network interactions.(3)A network interactivity identification model for the GBEC was established.A social network interactivity identification model for the GBEC was established based on the Social Network Analysis(SNA).A value network interactivity identification model for the GBEC was established based on the Stakeholder Value Network Analysis(SVNA).A technology network interactivity identification model for the GBEC was established based on the Fuzzy Kano Model(FKM)analysis.It was combined with the engineering practice,and the application process of the interactivity identification model for the social,value,and technology networks of the GBEC was proposed.(4)The network interactivity evaluation method of the GBEC was proposed.The network interactivity evaluation index system of the GBEC was established based on the network interactivity identification model.The network interactivity evaluation method and application process of the GBEC,which can be applied to different evaluation requirements,was established based on the Analytic Network Process(ANP)and validated by examples.(5)A case study on the network interactivity of the GBEC was conducted.The GBEC and N-GBEC were established and applied combined with three typical engineering examples.The network interactive effect and identification model for the GBEC were tested;the optimization path for the GBEC and N-GBEC was proposed,and the operability of the method used to evaluate the network interactivity was verified.
