AbstractThe purpose of this paper is to investigate the application of building information modelling (BIM) for asset management. It will discuss what tools and processors are used for applying BIM for asset management in construction projects. The method comprises a literature review of 33 projects that have applied BIM or planned to apply BIM for asset management functions. The findings show that a combination of software, hardware, processors, and standards can enable the BIM models to be integrated with the asset management systems. It facilitates easy extraction of information, avoid errors and duplication of work. The most popular way of developing a BIM-based asset management system is incorporating BIM asset data with CMMS or CAFM systems used for asset lifecycle and maintenance management. Engagement of stakeholders related to the operation phase is required as early as possible. Consideration should be given for protecting the information generated within the cyber environment. The research shows how BIM related tools and processors could be integrated to successfully implement BIM enabled asset management. The knowledge can be potentially useful for planning or implementing BIM enabled asset management systems. The research provides insight on the application of BIM for asset management in construction projects globally.

AbstractThe potential health and safety (H&S) benefits of advanced technologies are not currently being optimized in the construction industry. This research aims to identify the technical, economic and social issues and their respective solutions of real-time H&S management technologies during their implementation and operation. A comprehensive literature review is conducted to analyse the technical, economic and social aspects of a number of example real-time H&S management technologies. Using the information gathered from the literature review, Social Construction of Technology approach is used to theoretically analyse each real-time H&S management technology by considering four aspects: technology, social groups who utilize or interpret the technology, problems encountered by each social group and solutions or mechanisms to solve those problems. The study shows that the most common technical issues are occlusions, background disturbances, disturbed line-of-sight and low battery power. Most of these systems have high implementation cost. There is a considerable resistance to physical tagging due to health and privacy concerns. Researchers continue to explore ways to solve the technical issues. However, attention to solving the economic and social issues is relatively low in comparison. The research outcomes will contribute to future innovations and improvements in performance and productivity associated with construction H&S.

Building integrated photovoltaics (BIPV) refers to photovoltaic or solar cells that are integrated into the building envelope (such as facade or roof) to generate ‘free’ energy from sunshine, and it is one of the fastest growing industries worldwide. However, up until now, there have been limited studies that analysed cost‒benefit and risk factors/barriers of BIPV from a supply chain perspective; and there have also been limited studies that provide strategies to industry and academics in order to encourage BIPV diffusion and application. The aim of this research is to identify the costs, benefits and risks of BIPV and propose suggestions for greater BIPV application, from a stakeholder perspective, through a comprehensive review of current literature. The results of this research show that whilst BIPV have high initial investment capital costs, there are significant long-term benefits to be achieved for clients, end users and the entire society. Further, the results also show that BIPV costs decrease and government policy support and incentives are required in order to promote wider BIPV application. In addition, this research has identified the fact that there was a lack of detailed BIPV cost data (including individual component costs) and lack of methods for BIPV cost‒benefit analysis, and there are risks and barriers in BIPV applications. Following this, this research provides a strategic framework and a number of suggestions to industry stakeholders for integration and collaboration within the BIPV supply chain in order to facilitate the cost reduction of BIPV. Finally, this study proposes several topics for future research. It is anticipated that the results presented in this paper have implications not only for government policy and product development and application, but also for academic research.

Peer-to-peer trading generates a consumer-centric market and encourages a bottom-up hierarchy, allowing consumers to choose the source of energy and conduct preference-based trading. Although peer-to-peer trading has promising benefits, its application in the real-world is limited and often not encouraged. This paper presents a systematic and comprehensive literature review of the business models of 50 peer-to-peer distributed renewable energy trading projects around the world. The aim of this study is to explore the strengths, limitations and challenges of peer-to-peer distributed renewable energy trading considering its prevailing business arrangements to identify the critical requirements for its uptake in the real-world market. The findings reveal that peer-to-peer distributed renewable energy trading has characteristics of both coordinated and decentralised markets. Peer-to-peer trading is very effective when combined with value-added services such as energy storage, demand-side management, energy optimisation and information services. The key strength of peer-to-peer trading is the use of distributed ledger technology (DLT) to provide a secure and transparent trading environment. The main limitations to the implementation of peer-to-peer trading in the real world are the lack of regulations on trading between peers, the lack of public awareness, the complexity of the technology and the lack of government motivation. This study will enable distributed energy resources (DERs) owners, utility companies and network operators to understand how to stay relevant and competitive in peer-to-peer trading markets.
