This study examined the factors that influence households’ intention to adopt solar energy solutions in Zambia. This, in view of low adoption rates of solar energy solutions even in the wake of a widespread electricity power generation deficit across sub-Sahara Africa (SSA) has plagued the region with daily electricity load shedding lasting several hours at a time. Given the vast potential for solar energy generation in the region, solar energy solutions have become an attractive option to grid-based electricity, and many households have intentions of adopting these solutions.

Through the lens of the theory of planned behaviour (TPB), the study surveyed adult household members in Zambia who contributed towards the household’s income. The participants were selected using the snowballing technique, which yielded a sample of 961 respondents. The results were analysed using structural equation modelling.

The results show that attitude, trust, benefits and subjective norms influence the intention to adopt solar energy solutions. Trust and benefits also influence the intention to adopt solar energy solutions indirectly through attitude. Therefore, measures aimed at increasing the adoption of solar energy solutions should focus on improving the attitude, perceived benefits, trust in the solutions and consider subjective norms.

The findings add to the understanding of the factors that influence the intention to adopt solar energy solutions in Zambia. Therefore, the findings can be used to inform measures aimed at improving solar energy uptake in Zambia. The study also reports on the previously unreported mediating role of attitude towards solar energy solution on the associations between perceived benefits and trust with solar energy solutions adoption intention.

Against a background context of Construction 4.0, this study aims to explore what digital leadership in construction firms is, why it is necessary and what considerations it involves. It provides a digital leadership considerations framework to aid organisational digital transformations.

To address the research question informing what digital leadership involves, an interpretivist study was conducted. Eleven purposively selected expert practitioners, including construction business leaders and company digital champions were surveyed using in-depth semi-structured interviews. This obtained insights and reflections on how construction leaders can impel digital transformations.

How construction leaders can embed the skills to drive such transformation in their firms, what the essential digital skills for construction businesses now are in Construction 4.0 and how leaders can attempt to evaluate the value of digital technology for their business practices, are all crystallised. Impacts of digital transformations on the construction workplace are also highlighted.

Because of this work, business leaders will be better equipped to lead and support further digital transformation efforts in Construction 4.0. Future research directions aid academics.

Clear definitions of digital transformation and digital leadership are provided, and a digital leadership considerations framework is provided to support firm-level digital transformations for Construction 4.0.

While previous studies have highlighted the importance of incorporating environmental sustainability in building designs, there is a paucity of studies that assess the extent to which design teams in developing countries consider environmental sustainability at the building design stage. Therefore, using Zambia as a case study, this study examined the extent to which infrastructure design teams in a developing country consider environmental sustainability at the design stage.

The study used a qualitative research approach using structured interviews because there are hardly any studies which have explored the extent to which designers incorporate environmental sustainability in infrastructure designs in developing countries. The data is analysed thematically using the ATLAS.ti software.

The results show that environmental sustainability is not an important design consideration because it is secondary to functional, technical and aesthetic considerations. Environmental considerations are also made in an ad hoc manner and when it is cost-effective for the project. Regulatory requirements pertaining to environmental protection are adhered to without any cost considerations. It was, therefore, theorised that building design teams in developing countries make technical, functional and aesthetic consideration during the infrastructure design stage ahead of environmental considerations.

There is a paucity of studies that have investigated whether building infrastructure designers consider issues of environmental sustainability at the design stage in developing countries. The findings have practical implications on how developing countries can foster environmental sustainability at the design stage and avoid generating a building infrastructure stock that will require environmental resilience adaptation in the future.

The study examined perceptions and beliefs that influence the intention to adopt solar energy solutions in the Zambian Housing Sector. This is important because empirical evidence for measures aimed at improving the adoption of solar energy solutions with SSA in general or a Zambian context, in particular, are largely missing from the literature.

Hierarchical multiple linear regression was used to analyse quantitative data collected through an online questionnaire survey. A total of 947 valid responses were obtained from a convenient sample of household heads.

The results show that attitude towards solar energy solutions, subjective norms, perceived benefits, perceived trust, knowledge about solar energy solutions, load-shedding and social norms, in that order of magnitude, influence the intention to adopt solar energy solutions. Perceived behavioural control, perceived risk and perceived cost did not influence the intention to adopt solar energy solutions.

The results provide empirical evidence of important factors to drive the adoption of solar energy solutions in Zambia. The results further show that knowledge about available solar energy solutions, rather than general knowledge about renewable energy, influence the adoption intention of solar energy solutions.

The purpose of this paper is to explore the perceptions and experiences of building practitioners in the adoption of renewable energy (RE) in commercial buildings in Nigeria.

A qualitative methodology was used guided by the principles of the Grounded Theory Method (GTM). Data were collected using in-depth semi-structured interviews with a purposive sample of five industry practitioners.

Five distinct factors emerged, namely, being compliant, change in mindset, normalising, being autonomous and identity. The research revealed the significance of contextual (cultural) peculiarities and the role identity plays in informing RE adoption. The findings substantiate the significance of RE adoption in the future practice of building practitioners and in ensuring environmental stability within the Sub-Saharan Africa (SSA) context.

The study focuses on commercial office buildings and attempts to provide contextual grounding to inform theory generation as part of a wider study.

This research contributes methodologically and empirically by providing grounded insight into the adoption of RE in commercial buildings. Thereby, enabling a much greater understanding of the issues associated with enhanced promotion and adoption by professionals and stakeholders, which can inform policy interventions. Furthermore, it will benefit further research within the SSA context and provide valuable lessons associated with adopting GTM in construction research.

The recent failures and insolvencies of organisations related to the modern methods of construction (MMC) have gained increased attention and controversy across the UK construction sector. Such failures are linked to their inability to achieve an economy of scale and drive key clients to accept the MMC as an alternative to traditional methods. This paper aims to unravel whether a phenomenon of “innovation negativism” has manifested and is contributing to public clients' indecision towards broader MMC, whether this is only linked to past negative experiences formed after the Second World War or whether additional contributing reasons exist to influence adoption.

This study focusses on exploring the decision-making of the UK public construction sector; therefore, this paper adopts a qualitative approach, utilising interviews with 14 carefully selected MMC experts, government advisors and public clients. The phenomenological stance adopted herewith enables the authors to make better sense of the perceptions of the interviewees, leading to the conceptualisation of the innovation negativism phenomenon.

The paper identifies nine themes that may be argued to promote a profound understanding of the MMC negativism influencing public clients' decision-making. The study has found that more than just the previous negative perceptions formulated post Second World War are driving innovation negativism in the UK public sector. Notably, the emerging themes are incomprehension, lacking evidence, communication, relationship history, bad experiences, uncertainty, inadequate experimentation, the business case and localism.

This study is the first construction management research that acts as a fair departure point to conceptualise the reasoning behind innovation negativism in the construction setting. Through mirroring demand's unipolarity for traditional methods, policy and decision-makers can now rely on the conceptualised reasoning to determine practical solutions to overcome clients' indecisions towards MMC.

Digital uptake amongst construction organisations is described as slow and ineffective, undermining a fundamental transformation and limiting construction firms from exploiting the digital benefits. In this space, meaningful research that utilises a qualitative approach in pursuit for employees' insights towards digital transformation is lacking. Such limited focus from previous efforts presents an opportunity to illuminate the determinants of an effective digital transformation that are, arguably, responsible for the status quo of low digital uptake in the construction sector. This paper aims to discuss the aforementioned idea.

This study adopts a qualitative approach to address the literature's digital discreetness in construction. The qualitative approach captures employees' perspectives through its unbounded characteristic of encouraging illustration and discussion.

This paper captures 35 digital transformation determinants under three clusters, namely, organisation related, i.e. hierarchy, size and management, people related, i.e. team orientation, training and knowledge and leadership related, i.e. awareness, attitude, approach and leaders' characteristics. Findings suggest a new set of arguments in relation to understudied factors and their influence on the digital uptake in construction organisations.

This paper offers empirical indication of the determinants believed to influence an effective digital transformation in construction organisations. Such conceptualisation is crucial and is depicted as perceived by construction employees and practitioners, which is a less biased approach than that of comparable studies that argue the viewpoints of industry leaders in isolation of other members of the hierarchy.

The importance of ethical considerations in the construction industry is acknowledged. This is particularly the case that the industry plays a significant part in a nation’s development. The Zambian construction industry has seen an increase in activity due, in part, to massive infrastructure development programmes adopted by successive governments, increase in foreign direct investment and housing development. The Zambian construction industry, like any other, is not immune to unethical behaviour. This study aims to investigate students’ perception of the prevalence of unethical practices in the Zambian construction industry. A review of literature demonstrated that a number of contextual factors including location can influence the perception of unethical practices. A focus on Zambia was therefore considered necessary.

In total, 121 students took part in a questionnaire survey to examine their perception of the extent to which unethical practices were prevalent in the Zambian construction industry.

The findings suggest that students perceived bribery/corruption and political/societal influences as the two most common unethical practices, while the least prevalent unethical practices were perceived to be alcohol/drug abuse and workplace violence. The findings are largely consistent with previous studies investigating the ethical perception of professionals in the Zambian construction industry. In addition, the findings suggests that when the year and programme of study are taken into consideration, the differences in perception of unethical practices are evident for these demographic groups.

This study provided an added dimension to the understanding of ethical issues in the Zambian construction industry as it was the first of its kind involving students’ perceptions. This paper therefore contributes to the list of countries where similar studies have been undertaken.

The education sector is at the forefront of developing tomorrow’s construction professionals. It is therefore important that with the current rate of change in the construction industry, education curriculum should be seen to be relevant. An area that is revolutionising the construction industry is the use of Building Information Modelling (BIM), including its potential for improving H&S on construction sites. This paper aims to focus on the perception of higher education (HE) students on the potential impact of 4D modelling on the management of site health and safety on construction sites.

A quasi-experimental approach was adopted to determine student’s perception of the extent to which 4D modelling and simulation can impact H&S management. Pre-test and post-test students’ perceptions of the value of 4D to management of health and safety were compared.

The influence of education was examined by using two main students groups, one group studying BIM modules within their course while the other group did not. Although minimal perception differences regarding key impacts of 4D were highlighted, the awareness differences were significant. The study demonstrated the perception of benefits regarding 4D for H&S being in the planning of site logistics, visualisation, programme accuracy and risk reduction. The study highlights the importance of relevant education, to increase awareness of 4D for Health and Safety.

While most of the studies reported in academic literature on education and training related to university/tertiary education, this study focused on the higher education level students. It considered this as an equally important cohort as the graduates will also contribute to health and safety management on construction sites. The study also demonstrated the value of including technology based H&S training to mirror developments in the construction industry.

Challenges to energy access in Nigeria have resulted in the widespread use of fossil fuel generating sets (generators) despite its renewable energy (RE) potential. Given the climate crisis, combined with the country's rapid population growth and expected rise in energy and building demand, transitioning to low-carbon electricity using REs like solar photovoltaic (PV) presents opportunities beyond securing its energy future. While PV use is growing in Nigeria, this is focused on the residential sector despite the identification of the commercial sector as a high energy consumer and a key platform for its integration. In line with this, this research aims to investigates the challenges to energy transitioning from generators to solar PV in commercial buildings.

A qualitative approach in line with grounded theory was adopted using in-depth face-to-face interviews with industry experts.

Two distinct but interrelated categories emerged: being held captive and being a saviour that represented a duality of systems, and/or processes formed the core category “Hostage Syndrome”. The core category (theory) was generated based on the explanations and expressions by participants about their concerns, interests, and the conditions under which they operate. The findings reveal the value attributed to generators beyond an operational role and the adjustments or mechanisms adopted by building professionals during their practice. It suggests a sphere of influence beyond the obvious financial and/or institutional aspects, as determining factors to what is viewed as sustainable which will be key to transitioning to REs.

This paper provides new and in-depth insight into understanding the conditions under which building professionals operate associated with their interpretations of “being sustainable”. The study highlights the need to consider psychological and cultural factors in the development of interventions, strategies and/or policies to support RE transition, particularly towards achieving a sustainable construction industry.
