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 Coordination in building an observatory: A case study of Eastern Anatolian Observatory (DAG)(SPIE-Int Soc Optical Engineering, 2018) Şahmalı, Ali Erkan; Yeşilyaprak, Cahit; Keskin, OnurEastern Anatolian Observatory (DAG) is designed to build on one of the summits of Palandoken Mountains in Erzurum, Turkey, at an altitude of 3,151 meters. The building is under construction since 2015 and expected to be completed in 2020. The building is designed as an integrated building, having operational departments, services, mechanical and electrical infrastructure for observations as well as cleaning and coating units, adjacent to the main observatory building. As one might expect this integration creates serious coordination problems between architect, engineers, telescope, enclosure, and cleaning & coating unit manufacturers. The construction progress of the investment is almost 20%. There are quite an amount of "lessons learned" in this period, and need to be developed by the parties, for their existing and future works. The building has so many challenges such as geological and geographical limitations, environmental and meteorological constraints, engineering and structural considerations, energy efficiency and sustainability, materials used and their performances at these limitations.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.Yayın Analysis of the benefits, challenges and risks for the integrated use of BIM, RFID and WSN: a mixed method research(Emerald Group Publishing Ltd, 2023-07-11) Seyis, Senem; Sönmez, Alperen MertPurpose The purpose of this study is to identify, classify and prioritize the benefits, challenges and risks for the integrated use of building information modeling (BIM), radio frequency identification (RFID) and wireless sensor network (WSN) in the architecture, engineering, construction and operation (AECO) industry. Design/methodology/approach This study relies on the mixed method approach which consists of systematic literature review, semistructured interviews and Delphi technique. A systematic literature review was performed and face-to-face semistructured interviews with seven subject matter experts (SMEs) were conducted for identification and classification purposes. Delphi method was applied in two structured rounds with eleven SMEs for prioritization purpose. These three research techniques were chosen to reach the most accurate data by combining different perspectives on the subject matter. Data gathered by these three methods was triangulated to increase the validity and reliability of this research. Findings Thirteen benefits, ten challenges and four risks for the integrated use of BIM, RFID and WSN were identified. The results could aid the practitioners and researchers comprehend the pros and cons of this integration by representing SMEs' valuable insights and perspectives about the current and future status, trends, limitations and requirements of the AECO industry. The identified risks and challenges show the requirements for future studies while the benefits demonstrate the capabilities and the potential contributions of this hybrid integration to the AECO industry. Originality/value The integration of BIM, RFID and WSN is still not commonly implemented in the AECO industry. Some studies focused on this topic; however, none of them reveals the benefits, risks and challenges for integrating BIM, RFID and WSN in a holistic manner. This research makes a significant contribution to the AECO literature and industry by uncovering the benefits, challenges and risks for the integrated use of BIM, RFID and WSN that could increase industry applications.
