At present, with more and more attention paid to the impact of buildings on the health and well-being of occupants, sick building syndrome (SBS) has become a global concern. Since the introduction of SBS by the World Health Organization (WHO) in 1983, thousands of research literatures have been published in this field. This paper systematically arranges knowledge development of SBS through bibliometric analysis, exploring the most influential countries, institutions, journals and scholars, as well as the main subject categories and keywords. Main path analysis (MPA) was used to list development trajectory under inheritance relationship of SBS knowledge, including symptom analysis, risk factors of SBS and the improved impact of ventilation on SBS and productivity. Furthermore, it is an emerging research trend to propose SBS solution in the building design stage.

The Internet of Things (IoT), as an important technical domain in the future, has received wide attention globally from different disciplines. The research output in this domain, therefore, grew rapidly in the past 10 years. This study deeply investigates the knowledge base and knowledge development trajectory of the domain since the IoT was proffered in 1999. By adopting basic statistical and keyword co-occurrence methods, the most influential countries, institutions, journals and scholars in the domain, as well as the division of core, hot keywords and subdomains, are investigated. By using the main path analysis method, a survey is conducted on the development trajectory of the domain on the basis of knowledge inheritance; the four core branches-industry, big data, cloud computing and IoT security; and the three application studies of industry, healthcare and smart city.

The relationship among stakeholders is complicated and full of collaboration barriers, which makes urban renewal an intersection of various contradictions. However, the existing literature considers the barriers to urban renewal independent of stakeholders, and the interaction between multiple stakeholders and barriers to collaboration has been ignored. Therefore, this study uses a literature review and expert interviews to identify stakeholders and their collaboration barriers in the process of urban renewal. Based on the results of expert questionnaires, a two-mode network model of stakeholder–collaboration barrier is constructed to clarify the complex interaction and reveal the power and status of stakeholders in a network relationship. The study found that each barrier was associated with at least three stakeholders, indicating the necessity of stakeholders to establish partnerships. Further analysis shows that the government, local and other administrative organizations, consulting parties, and developers are the most influential stakeholders. The vague boundary of property rights, lack of expert advice and expertise, and different stakeholder awareness were identified as key barriers affecting sustainable collaboration. Finally, this study proposes and validates five strategies to promote collaboration among stakeholders. This study helps practitioners identify the priority problems to be solved under limited resources and provides effective measures to promote stakeholder collaboration.

Interdisciplinary integration is a new driving force in development of science and technology. Neuroscience, a powerful tool for studying human physiology and psychology that is greatly interconnected with the field of building construction, has attracted numerous research attention. In this paper, we systematically review the interdisciplinary applications of neuroscience tools using bibliometric methods. We report that the built environment, construction safety, architectural design, and occupational health are the main areas of research attention, while thermal comfort, air quality, hazard recognition, safety training, aesthetic design, and biophilic design, among others, comprise the most frequently studied topics with regards to application of neuroscience tools. Currently, eye tracking and the electroencephalogram are the most commonly used tools in the field of building construction, while functional near-infrared spectroscopy, functional magnetic resonance imaging and trigeminal nerve stimulation are still at their initial stage of application.
