“…At present, sustainable construction faces many challenges globally, including the incompetence of complete life-cycle data arrangement and conducting data analysis to share with project participants [37]. BIM can store and manage building project data on energy consumption and offer detailed work-flow data during construction operation [38]. Thus, users can easily upload, extract, check, or transform information by using the BIM platform [39].…”

Building information modeling (BIM) is based on 3D models for collaborative management of information, which leads the innovative development of information transformation in the construction industry. In recent years, sustainable construction has become a hot topic in construction research. With the concept of sustainable development, this type of construction advocates for the sustainable optimization of construction models and processes. A person’s good behavior can bring enormous potential, which is critical for the promotion of new technology in new areas. Nowadays, the integration of BIM technology and sustainable construction has increasingly attracted attention in the industry of construction. But many issues and gaps still exist when using them. The aim of this study is to investigate the intrinsic relationship between BIM application and sustainable construction from the perspective of user application behavior, and to reveal the key influential factors of BIM application behavior in order to improve the application efficiency of BIM in sustainable construction. Specifically, the present study builds a theoretical model by integrating the theory of planned behavior and BIM application. Based on a questionnaire survey of 353 BIM users, we conducted an empirical analysis using the structural equation model method. The results showed that the perceived usefulness and ease of use of BIM technology are the key influential factors in behavior attitude. BIM behavior intention, actual behavior, and behavior attitude have a positive effect on sustainable construction. Ultimately, practical support is provided for the effective integration of BIM with sustainable construction in China.

“…Hoxha et al [6] discussed on how to address data uncertainties through contribution and sensitivity analysis and draws attention to the implications for LCA. At the same time, Najjar et al [38] highlighted several gaps, such as incomplete databases or insufficient data at the early design phases that reduce the potential for LCA applications. Most studies present simplified hypotheses due to lack of incoming data, especially for EOL scenarios in which "only demolition and disposal to landfill sites will be considered" [39].…”

“…However, most BIM-based LCA methods papers do not precise the LOD for the LCA [25,56]. To achieve reuse, we should provide and integrate necessary BIM-attached information to simulate the assembly and disassembly process, such as a deconstruction plan [57], material properties enabling LCA performing [38]. Indeed, LCA requires rigor and comprehensive data obtained at an advanced stage of the project, whereas engineers need a simplified LCA in the early stages when we can still change the design choices influencing the environmental impact with a low LOD in the BIM model.…”

A BIM-Based Framework and Databank for Reusing Load-Bearing Structural Elements

et al. 2020

In a context of intense environmental pressure where the construction sector has the greatest impact on several indicators, the reuse of load-bearing elements is the most promising by avoiding the production of waste, preserving natural resources and reducing greenhouse gas emissions by decreasing embodied energy. This study proposes a methodology based on a chain of tools to enable structural engineers to anticipate future reuse. This methodology describes the design of reversible assemblies, the addition of complementary information in the building information modeling (BIM), reinforced traceability, and the development of a material bank. At the same time, controlling the environmental impacts of reuse is planned by carrying out a life cycle assessment (LCA) at all stages of the project. Two scenarios for reuse design are applied with the toolchain proposed. A. "design from a stock" scenario, which leads to 100% of elements being reused, using only elements from stock. B. "design with a stock" scenario, which seeks to integrate as many reused elements available in the stock as possible. The case study of a high-rise building deconstructed to rebuild a medium-rise building demonstrated that the developed toolchain allowed the inclusion of all reuse elements in a new structural calculation model. Sustainability 2020, 12, 3147 2 of 24 the largest exploiters of natural resources [8], accounting for between 40% of the total raw materials consumption [9] and 50% [10].This growing development has repercussions on the emission of GHGs, among other indicators. In France, the construction and building industry is the leading emitter of GHGs [11], i.e., 33% of total GHGs. Several studies confirm this number worldwide [6,12,13]. Kumar Dixit et al. [8] define the embodied energy (EE) and embodied carbon (EC). EE during the construction phase is the amount of energy used for the extraction of raw materials, the production and transport of building components as well as the building construction and end-of-life (EOL). Moreover, EC refers to the associated GHG emissions [3]; the operating energy during the operation phase as energy consumption and associated operational carbon emissions during the use phase of buildings (heating, cooling, etc.). The average value of EE is 50% of the total primary energy demand [14]. The share of operational energy seems to decrease recently (even disappearing in passive or zero energy buildings) with technical progress and, therefore, the share of EE increases [15].Another impact of the construction sector is due to waste generation [5,16]. Most of the literature focuses on waste management, which shows a great interest in reducing the construction and demolition waste (CDW) generated by the construction sector as it represents around 40% of the waste produced [17]. Cai et al. [18] and Lismont et al. [19] explained that in Europe, about 25-30% of the waste result from the building sector amounting to 870 million tons annually and Brütting et al. [3] estimated this share at more than a third ...

“…The study [7] evaluates the relevance of each life cycle stage in relation to the overall environmental and economic impact on residential building energy refurbishment projects. Another study [8] once again integrates building information modeling (BIM) with life cycle assessment (LCA) and presents the outcome of multi-storey office building in evaluating environmental impacts of building materials. Most of the negative environmental impacts are occurring during the manufacturing and operation phases.…”

Sustainable construction and its architecture of buildings seeks to minimize the negative environmental impact of buildings by efficiency in the use of materials, energy, and development space and the ecosystem at large. Sustainable buildings use a conscious approach to energy and ecological conservation in the design of the built environment in cities. This article is devoted to the environmental assessment of three family houses which represent three different material and design solutions. The houses were evaluated through the Slovak building environmental assessment system (BEAS), which has been developed for Slovak conditions at the Faculty of Civil Engineering, TUKE. This study shows that the influence of green design, compared to traditional construction, is important and more beneficial for the practice of designing sustainable buildings. It creates the most comprehensive relationship between the building and its environment and significantly affects building sustainability.
