Yayın Analyzing the benefits and challenges of building information modelling and life cycle assessment integration(Springer, 2020) Azizoğlu, Heval Botan; Seyis Kazazoğlu, SenemPrevious studies show that the architecture, engineering and construction (AEC) industry contributes up to 1/3 of global GHG emissions. With the aim of mitigating negative impacts of AEC industry on the natural environment, the integrated use of advanced technological instruments has been increasing in the last decade. The integration of Building Information Modelling (BIM) and Life Cycle Assessment (LCA), which is one of the cutting-edge technological instruments, provides reduction of the total time spent and the improvement of the application while minimizing the environmental impacts throughout the life cycle of the facility. The main objective of this research study is to identify the benefits and challenges of BIM and LCA integration. In order to achieve the research objective of this study, a comprehensive literature review was conducted. Twenty-two types of benefits and seven types of challenges were identified for the integrated use of BIM and LCA in the AEC industry. The major contribution of this study is a comprehensive identification of the benefits and challenges of BIM-LCA integration. The results of this study may contribute to an increase in the utilization of the BIM-LCA integration in the AEC industry that in return allows decreasing negative environmental impacts of buildings through their life-cycle.Yayın Analyzing the benefits and challenges of the building information modelling and life cycle assessment integration(Işık Üniversitesi, 2019-07-17) Azizoğlu, Heval Botan; Seyis, Senem; Işık Üniversitesi, Fen Bilimleri Enstitüsü, İnşaat Mühendisliği Yüksek Lisans ProgramıThe architecture, engineering and construction (AEC) industry involves the large quantities of material and energy consumption. Previous studies show that the AEC industry consumes about 40 percent of primary energy utilization and contributes up to more than half of global GHG emissions. With the aim of decreasing these negative impacts of AEC industry on the natural environment, the integrated use of advanced technological instruments has been increasing in the last decade. One of the promising technological instrument integrations is the collaborative use Building Information Modeling (BIM) and Life Cycle Assessment (LCA) which is able to decrease negative impacts of AEC industry on natural environment in an e ective and e cient manner. The objective of this MS thesis is to identify, classify and prioritize the bene ts and challenges of the integrated use of Building Information Modelling and Life Cycle Assessment in the AEC industry. In order to achieve research objectives of this thesis, a comprehensive literature review, semi-structured interviews with experts and Delphi method were performed. The interrater agreement and signi cance-level statistics were conducted for analyzing and validating the consensus among the Delphi method participants. Results of this study provide twenty-two types of bene ts and seven types of challenges for the integrated use of BIM and LCA in the AEC industry. The contributions of this thesis are a comprehensive identi cation, classi cation and prioritization of the integrated use of BIM and LCA. The results of this study may contribute to extend utilization of BIM-LCA integration in the AEC industry.
