The architecture, engineering, and construction sector requires carbon-intensive materials, such as steel, in the construction process and generates a large amount of waste in the life cycle. This causes global warming and waste problems. The demand for the reuse of construction materials is increasing, although it is not the convention, to reduce the environmental impact. Although the sustainable effect of the reuse of materials has been proven in several studies, materials are not always reused in practice, owing to the lack of an information system for reusable materials and the economic uncertainty. In this study, we propose a framework for designing structures using reusable steel beams. The design framework consists of a material bank and a design support tool. The material bank provides information on reusable materials based on the building information modeling. The design support tool generates efficient material procurement plans and provides information about the environmental and economic impact of the project. In a case study used to verify the framework, CO2 emissions were reduced by up to 77% through material reuse, which was consistent with the results of previous studies. However, owing to the cost of processing reusable materials, the overall cost was found to increase by up to about 40%. Therefore, an economic analysis over the entire life cycle when using reusable materials needs to be done.

Lightweight foamed concrete brick is new construction materials. It gives a prospective solution to building construction industry, this research aims to study the cost, dead loads, environmental issues and energy consumption from using lightweight foam concrete bricks as construction materials by utilizing building information modeling technique. The results obtained from this modelling proved that the cost of brick work using lightweight foamed concrete units of grade A (2000 kg/m3) and B (1800 kg/m3 ) is higher by (19.4% and 11.9%) respectively than the activity cost using traditional fired clay bricks. For grade C (1600 kg/m3) that cost was very close to fired clay bricks (+2.9%). while the construction of brick work using light weight foamed concrete units of grade D (1400 kg/m3) and E (1200 kg/m3) was lower by (8% and 18.6%) than fired clay bricks. Besides that, the dead load generated by building units was decreased by (7.7-38.5%) for grade (B, C, D, E) than the load of fired clay bricks, while the load generated from used lightweight foam concrete bricks grade is very closed to fired clay bricks (+2.5%). There was a reduction in energy consumption by the rate of (4.1-62.2%) for heating and (9.8-73.4%) for cooling as wall sharing in energy consumption. Environmental analysis showed sustainable potential so that the production of lightweight foamed concrete units reduces CO2 emission by (46.5-67.9%) compared with the fired clay bricks. Finally; it can be concluded that building units produced in this research with LWFC, characterized with properties can efficiently compete the fired clay bricks.

Building Information

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.

AbstractIn the last few years, particular focus has been devoted to the life cycle performance of fastening systems, which is reflected in increasing numbers of publications, standards and large-scale research efforts. Simultaneously, experience shows that in many cases, where fastening systems are implemented – such as industrial facilities – the design of fasteners is governed by fatigue loading under dynamic characteristics. In order to perform an adequate design and to specify the most efficient and appropriate fastening product, the engineer needs to access and process a broad range of technical and commercial information. Building information modelling (BIM), as a data management method in the construction industry, can supply such information and accommodate a comprehensive design and specification process. Furthermore, the application of BIM-based processes, such as the generation of a BIM-model, allows to use the important information for the construction as well as the life cycle management with different actions and time dependencies of the asset and its components. As a consequence, the BIM model offers the potential to correlate different data relevant for achieving the goals of the respective application, in order to ensure a more effective and correct design of the fastening. This paper demonstrates such a BIM-based design framework for an Industry 4.0 case, and in particular, the installation of a factory robot through post-installed anchors under fatigue-relevant loading in concrete.
