In the context of the general trend to accelerate change, the actual goal of scientific research in the field of construction is to analyze and design the stages of the life cycle of a construction object. The object of the study becomes the information model of the life cycle of the building. It is studied and modeled based on the concept of real estate development and using the methods of project analysis of the construction project. The widest possibilities for obtaining and analyzing data on the state of a construction object, as well as the possibilities of systematizing information flows and information modeling of different periods of its life cycle, are realized in the approach of BIM modeling of buildings and structures. With the help of BIM-modeling tools, mandatory stages and possible phases of the life cycle of a building object can be represented as hierarchically and sequentially related information flows, in which the attributes of each stage of the life cycle are formed under the influence of the preceding stages and of special factors for the considered stage. As a result, the project documentation should reflect the decisions aimed at providing the necessary conditions and opportunities for subsequent periods of the life cycle of the construction object, as well as the most adapted for the predicted changes and transformations for all future stages and phases. The analysis of characteristics and the developed structure of simple and complex construction works allows determining for each stage and phase of the life cycle of a construction object: interconnection of information flows, composition and content of the information model of the building required for the work of specialists.

Traditional energy analysis in Building Information Modeling (BIM) only accounts for the energy requirements of building operations during a portion of the occupancy phase of the building’s life cycle and as such is unable to quantify the true impact of buildings on the environment. Specifically, the typical energy analysis in BIM does not account for the energy associated with resource formation, recycling, and demolition. Therefore, a comprehensive method is required to analyze the true environmental impact of buildings. Emergy analysis can offer a holistic approach to account for the environmental cost of activities involved in building construction and operation in all its life cycle phases from resource formation to demolition. As such, the integration of emergy analysis with BIM can result in the development of a holistic sustainability performance tool. Therefore, this study aimed at developing a comprehensive framework for the integration of emergy analysis with existing Building Information Modeling tools. The proposed framework was validated using a case study involving a test building element of 8’ × 8’ composite wall. The case study demonstrated the successful integration of emergy analysis with Revit®2021 using the inbuilt features of Revit and external tools such as MS Excel. The framework developed in this study will help in accurately determining the environmental cost of the buildings, which will help in selecting environment-friendly building materials and systems. In addition, the integration of emergy into BIM will allow a comparison of various built environment alternatives enabling designers to make sustainable decisions during the design phase.

Material Information

Materials play a central role in product manufacturing, contributing to each phase of product development in the form of either a component or process material. As the product revolves around materials, so does much of the product information. Material information plays a significant role in the decision making process at any stage of the product life cycle, especially with respect to the sustainability of a product. Material information in the manufacturing stages of a product’s life cycle will relate to the processes used in manufacturing and assembling individual components. The material properties may determine what processes can be used and how these processes should be controlled. To support sustainable manufacturing, the impacts of material choice should be considered during design, when resources are being committed. When comparing material alternatives at design time, it is not as simple as saying one material is “more sustainable” than another. Many different factors determine the sustainability of a product, and each of these factors may be influenced by multiple material properties represented through various information requirements. In order to develop a material information model that can satisfy these information requirements, we need to carefully study the requirements from an information modeling perspective. In this paper, we use activity models to describe design and manufacturing scenarios that rely on the availability of proper material information for sustainability decision making. We will use these models to first define specific scenarios and then to identify the types of material information that is typically required in these scenarios, and collect and categorize key concepts. Based on this study, we will make recommendations that will aid the development of a useful material information model for sustainable decision making.

Injection molding (IM) has been the most widely used manufacturing process for making plastic products mainly due to its high efficiency and manufacturability. The design of injection molding systems relies heavily on material data and related information. The availability of right material information at right time is of utmost importance for the design, operation and maintenance of the injection molding process. In this paper, a concise, and conceptual Injection Molding Material Information Model (IM-MIM) is proposed to support necessary computer-based modeling, calculation and management of material data. In this paper, we study different steps of the IM process from the information-modeling viewpoint to identify the role and influence of material properties and behaviors in decision-making process. We further developed a four-level IM-MIM model framework, which provides a foundation for different material-related activities or analyses. Several key components in the IM-MIM, which consists of the material data, physical and behavioral properties, thermodynamic and transport properties, and other material information like rheological and mechanical properties, are presented in detail.

Industrialization has been widely regarded as a sustainable construction method in terms of its environmental friendliness. However, existing studies mainly consider the single impact of greenhouse gas emissions or material consumption in the construction process of industrialized buildings, and pay less attention to ecological pollution and community interest, which leads to an insufficient understanding. There is an urgent need to systematically carry out accurate assessment of comprehensive construction environmental impact within industrialized building processes. Various methods, including face-to-face interviews, field research and building information modeling (BIM), were used for data collection. Four categories selected for the study included resource consumption, material loss, ecological pollution, and community interest. A life cycle assessment (LCA) model, namely input-process-output model (IPO), is proposed to analyze the construction environmental impact of the standard layer of industrialized buildings from four life cycle stages, namely, transportation, stacking, assembly and cast-in-place. The monetization approach of willingness to pay (WTP) was applied to make a quantitative comparison. Results reveal that the assembly stage has the largest impact on the environment at 66.13% among the four life cycle stages, followed by transportation at 16.39%, stacking at 10.29%, and cast-in-place at 7.19%. The key factors include power consumption, noise pollution, material loss, fuel consumption and component loss, which altogether account for more than 85% of the total impact. Relevant stakeholders can conduct their project using the same approach to determine the construction environmental performance and hence introduce appropriate measures to mitigate the environmental burden.

Building Information

Building Information Modeling (from English, Building Information Modeling, BIM) – the use of a general digital representation of an object under construction to facilitate the design, construction and operation processes in order to create a reliable basis for decision making. The Building Information Model (from English, Building Information Models, BIMs) is a set of structured and unstructured information containers (datasets) within a holistic information system, containing the necessary geometric, physical, functional and other characteristics of an object, which are a source for documentation accompanying the life cycle of an object (project documentation, estimates, etc.). The content of the construction information model is identical to the content of the project documentation, expanded with additional data. Within the construction industry, it is the implementation of specific tasks and procedures applied to the processes of entering, processing, creating and transmitting data to ensure the accuracy and integrity of information throughout the entire life cycle of an object, based on the definition of Information Management. This is to guide the implementation of BIM in an organization, ensure that BIM-related goals are achieved, and support the development / delivery of new services and the effectiveness of information modeling. The implementation and development of ВIM technologies requires the creation of communities that will serve as a tool for the promotion and implementation of ВIM technologies. In Ukraine, there is no expert environment on ВIM at the state level, but it is available in business. Therefore, the logical formula for creating a common platform for the promotion of VIM would be to involve representatives of all stakeholders with equal voting rights: the state, business, the public. It is proposed to create a community of UA BIM Task Group for the period necessary for sufficient integration of ВIM into the construction industry (approximately 10-15 years). The organization should consist of three components: membership; expert; secretariat.

In the conditions of rapid scientific and technological progress, the technologies development pace of designing buildings and structures began to outstrip the practical application of them in the domestic market in comparison with the countries of the western world. Ukrainian building design tools have ceased to be internationally competitive. In these circumstances, it is especially important to introduce new and improve existing methods and tools for modeling buildings and structures. An important task for a modern designer is the ability to use a computer model at various stages of the building's life cycle, namely: design, construction, operation. To solve this problem, one can apply a new design method - Building Information Modeling (BIM). The purpose of this research is to explore the possibilities of using information modeling technologies for buildings as a means of their life cycle managing. The scientific and practical importance of the work stands in the possibility of introducing of information modeling technologies of buildings not only as a new design method, but also as a means of managing of the life cycle of the building at all its stages. The results of the research are based on the analysis of literary sources and practical experience of the authors. The article revealed the possibility usage of building information modeling as means of managing of the life cycle of building and structures. There is considered options and the main problems of information modeling application on different stages of buildings life cycle. In this paper, the main functions of building information modeling, which are necessary for managing of the life cycle of buildings and structures, have been analyzed and formulated. The practical importance of the results of this paper is in the presentation of the proposed functions and development prospects of building information modeling tools.
