The aim of the research presented in this paper is to provide information on the common problems of healthy homes in the context of architectural design deficiencies. Especially because determining the status of a healthy house is particularly challenging if the design is poor.

Qualitative methods, i.e. interviews, site visits and graphic elicitation diagramming were used in two different stages of data collection. They were then analysed using thematic analysis.

The findings show that the architectural elements can have positive or negative effects on the health and safe environments. The quantity of doors and the use of transparent glass have largely contributed to the thermal transmission and increased indoor temperatures. The roof aluminium sheets and absence of vents inhibited indoor heat loss. This has led to discomfort and overuse of air-conditioning units, particularly during the COVID-19 pandemic where most households stayed/worked from home. The inappropriate height of the ceiling and roof made it challenging for maintenance purpose, reducing safety levels, which could result in physical injuries.

The concept of healthy homes is not new. Studies have been conducted in Western countries and in the field of healthcare. However, there is lack of study in built environment particularly in developing countries and inadequate inter-disciplinary and empirical research to connect the healthcare field. The pervasive and recurring design deficiencies in the construction industry remain a source of unhealthy homes, which must be addressed. Future investigations are necessary to expand the conclusions that can be drawn from this paper for health equity within the society and nation.

The Internet of Things has made the shift to the digital era possible, even though the Architecture, Engineering and Construction (AEC) sector has not embraced nor integrated it within the core functions compared to other sectors. The need to enhance sustainable construction with the adoption of Internet of Things in this sector cannot be overemphasized. However, the real-world applications of Internet of Things in smart buildings remain relatively unexplored in the AEC sector due to several issues related to deployment and energy-saving potentials. Given these challenges, this paper proposes to identify the present state of development and research in Internet of Things and smart buildings, identify Internet of Things clusters and applications in smart buildings.

Bibliometric analyses of papers from 2010 to 2023 using the Scopus database and scientometric evaluations using the VosViewer software were undertaken. The proper search keyword was identified by using the phrases “ Internet of Things” and “Smart Building”. A total of 1158 documents in all, written by 3540 different writers, representing 2285 different institutions from 97 different countries were looked at. A metasynthesis was conducted and a system of Internet of Things applications in a smart building is illustrated.

The development of IoT and Smart Buildings is done in two phases: initiation (2010–2012) and development phase (2013–2023). The IoT clusters comprised Internet of things, energy efficiency, intelligent buildings, smart buildings and automation; while the most commonly used applications were analysed and established. The study also determined the productive journals, documents, authors and countries.

Documents published in the Scopus database from 2010 to 2023 were considered for the bibliometric analysis. Journal articles, conference papers, reviews, books and book chapters written in English language represent the inclusion criteria, while articles in press, conference reviews, letters, editorials, undefined sources and all medical and health publications were excluded.

The results of this study will be used by construction stakeholders and policymakers to identify key themes and applications in IoT-enabled smart buildings and to guide future research in the policymaking process of asset management.

The study utilised bibliometric analysis, scientometrics and metasynthesis to investigate Internet of things applications in smart buildings. The study identified Internet of things clusters and applications for smart building design and construction.

With the recent increasing relevance of sustainability, multinational enterprises are faced with divergent stakeholder demands and persistently shifting priorities. This study aims to examine stakeholders’ perceptions of the sustainability performance of a gold mining subsidiary in Ghana.

Using a purposive sampling technique, the authors interviewed managers and employees of the case enterprise, officials of regulatory institutions and host community members on their perceptions of the case enterprise’s sustainability performance. The authors triangulated the opinions expressed by these stakeholders with data from annual reports. The data were analysed through the lens of stakeholder theory.

The authors found that while members of the host community and the regulatory institutions were keenly interested in the case enterprise’s social and environmental activities, they perceived their performance as unimpressive, considering the economic benefits derived from the mining operations. On the contrary, the managers and employees of the case enterprise were satisfied with their environmental compliance and social intervention programmes, even though the company’s economic position had declined. The authors submit that the variations in the sustainability performance perceptions among the stakeholders are due to the lack of a deeper understanding of the other stakeholders’ expectations.

To equitably satisfy diverse stakeholder expectations, the study highlights the role of stakeholder collaborations in understanding the expectations of more salient stakeholder groups such as community members and employees, as well as the lesser salient groups such as academics. It also demonstrates the fluidity of sustainability and its benefits in designing a consensual sustainable management strategy. This implies that managers of the case mining enterprise make the necessary efforts to meet the diverse stakeholder needs while attaining their primary objective of creating wealth for shareholders.

Compared to advanced economies, studies on sustainability performance in emerging economies are limited. Nonetheless, these limited studies leave out stakeholder perceptions, focusing more on quantitative performance indicators. Using thematic and content analyses, the authors investigate stakeholder perceptions on the sustainability performance of a case mining subsidiary operating in Ghana. The study focused on Ghana because it is ranked with South Africa as the top two producers of gold in Africa. Nonetheless, unlike South Africa, Ghana faces more sustainability challenges from the mining sector due to weak institutions in enforcing sustainability standards.

Using a subsidiary of a multinational mining company in Ghana as a case, the purpose of this study is to examine the formal and informal forms and channels of sustainability reporting in the emerging economy’s context.

Semi-structured interviews were conducted amongst managers and employees of the mining company and members of their host community. Based on the interview themes, archival data were extracted from the 2020 Integrated Annual Report of the case company to corroborate the results from the interviews.

The authors found that most of the stakeholders from the host community interviewed were not aware and, to an extent, not interested in formal sustainability reports. In place of that, the management of the mining subsidiary uses informal channels of communication, including meetings and durbars, to verbally engage the local community and their representatives on sustainability matters. Whilst the formal sustainability reports met the internal requirements set by the parent company, the informal engagements were critical for gaining external legitimacy from the host community and other interest groups. Hence, the authors argue that mining companies and their subsidiaries, particularly in developing economies, need to consider informal forms of sustainability reporting alongside the formal channels to engage local communities to address sustainability issues and avert disruptions to their operations.

Sustainability reporting studies have focussed mainly on annual reports published in print or corporate websites, ignoring informal forms of sustainability reporting. This study sheds light on the informal forms of sustainability reporting. This is important as formal forms of sustainability reporting may be less useful for engaging local mining communities in developing economy contexts.

Building energy efficiency is an inescapable part of the solution to Africa's sustainable development; its implementation can result in cost effective ways that can contribute to economic and social development as well as environmental sustainability. Despite this, a number of factors including financial barriers and market barriers are perceived by policy makers and building designers to influence the efficient use of energy in buildings. The purpose of this paper is to investigate the perceptions of architects in relation to the challenges of building energy efficiency in Ghana.

From a review of pertinent literature 18 factors were identified as challenging. Empirical investigation was carried out using survey questionnaire. The consideration of overlapping aspects of the study largely motivated the use of factor analysis to analyse the data which made it possible to make scientific deductions and built explanations from the results.

The study derives five brands of uncorrelated variables that better explains challenges faced in implementing building energy efficiency in Ghana. These variables include financial barriers, information barrier, private sector participation, behavioural barriers and production barrier. The study provides insight on the contextual provision of realities faced in implementing building energy efficiency in Ghana.

Key contribution of the paper to the body of knowledge is manifested in the use of the principal component analysis. This has rigorously provided understanding into the complex structure and the relationship between the various knowledge areas of building energy efficiency barriers in Ghana.

The current movement toward digitisation has promoted the adoption of smart building technology globally. Despite its advantages, its usage in developing countries such as Nigeria is still very low. Therefore, the purpose of this paper is to investigate construction professionals' awareness of smart building concepts (SBCs) in the Nigerian construction industry and identify the parameters by which SBCs can be measured.

A quantitative survey was carried out using a questionnaire to gather relevant data in the study area. This paper was conducted on 363 registered construction professionals in the Nigerian construction industry. The collected data were analysed using descriptive statistics and Kruskal–Wallis H test analysis.

This paper indicated that the majority of Nigerian construction professionals are aware of SBCs. Furthermore, the Kruskal–Wallis H test shows no significant difference between the awareness level of the various construction professionals. This paper further revealed energy management systems, IT network connectivity, safety and security management systems and building automation systems as the most significant parameters in which SBCs can be measured.

This paper identified significant parameters influencing SBCs awareness in the Nigerian construction industry. These parameters can be integrated into the building during the design stage and can be incorporated into the policymaking process of construction firms to promote the awareness of SBCs and encourage practices related to construction sustainability.

This paper provides empirical evidence on the awareness of SBCs among construction professionals and significant parameters influencing awareness in the Nigerian construction industry.
