Abstract
Purpose
In the era of climate change, the need to ensure that buildings are energy efficient cannot be overemphasised. Studies have shown that building retrofitting can improve energy efficiency (EE) and sustainability. There may be hindrances to retrofitting for energy efficiency. Extant literature and policy documents on Zimbabwe suggest a better framework to help stakeholders manage their existing buildings by addressing challenges and policy inconsistencies. This study appraises and critically discusses the challenges facing retrofitting Zimbabwe’s buildings for energy efficiency.
Design/methodology/approach
The research adopted a quantitative research design using a questionnaire survey distributed to the respondents knowledgeable in building retrofitting and energy efficiency in Zimbabwe. The data were analysed through various statistical approaches (descriptive and inferential). The inferential tests include the Shapiro–Wilk test, Kruskal–Wallis H-test, exploratory factor analysis and heterotrait-monotrait ratio analysis to develop the structural equation model that validated the challenges for retrofitting buildings.
Findings
The results revealed the challenges of retrofitting buildings for EE in Zimbabwe, and a structural equation model was developed that clustered the key challenges into three main groups. This includes inadequate finance to invest in energy, outdated building by-laws and the unavailability of raw materials to achieve energy efficiency.
Originality/value
By appraising the challenges facing retrofitting buildings for energy efficiency in Zimbabwe, this study provides insights into the contextual factors that can enhance energy efficiency and sustainability in other developing countries. The study’s practical implications will positively impact the Green Building Council and other stakeholders interested in improving energy efficiency in the built environment.

Abstract
Purpose
The regulation of the construction industry remains a significant obstacle to economic progress in developing nations. Therefore, this study aimed to assess the efficacy of the legislative framework in the construction industry, focusing on Eswatini. The construction industry plays a critical role in the upliftment of the economy and an effective and efficient legislative framework is essential to ensure that as a developing country, Eswatini derives maximum benefits from the sector.
Design/methodology/approach
A phenomenological research design was used to explore stakeholders’ perceptions about the purpose of the legislative framework in the Eswatini construction industry and to establish the effectiveness of the current legislative framework in fulfilling its mandate. The data were collected using semi-structured interviews with open-ended questions. A total of 45 participants occupying different positions within the construction industry were selected using purposive sampling. The data were analysed thematically.
Findings
The results reiterate that the legislative framework’s purpose is to regulate, control and guide sectoral operations, including enforcing compliance with statutes and payment of construction levies. However, the legislative framework does not effectively fulfil its purpose of addressing stakeholder needs. Overall, the findings indicate shortcomings and inefficiencies within the framework aimed at regulating the construction industry of Eswatini. The inefficiencies have a great potential of defeating the purpose of the entire framework.
Research limitations/implications
Regarding implications for future research, the current study has set a new pathway for legislative framework analysis and evaluation. Therefore, future research on the topic can build on the current study and compare the legislative frameworks across developing countries. The purpose would be to establish the similarities and differences, and to identify strengths and weaknesses, possibly leading to established principles of what works in a given context. Other studies on the topic could focus on benchmarking against developed countries on how they measure the efficacy of the legislative framework within their constriction industry.
Practical implications
Based on the preceding, these findings may apply to similar developing countries at a similar stage of construction industry development. However, the findings should be considered within the limitations of the study. The focus was on developing countries, particularly the Eswatini context. Each country presents a unique context and challenges, so the findings should be cautiously generalized.
Originality/value
While other studies in different contexts focus on developing legislative frameworks, the current study evaluated an existing legislative framework using defined criteria. The current study made a unique contribution by streamlining the features of effective and ineffective legislative frameworks. Hitherto, such information was scattered in literature but has been consolidated and applied empirically. Thus, the study has set benchmarks for analysing and evaluating legislative frameworks in developing countries.

Abstract
Purpose
The green building (GB) market is maturing after years of practice; therefore, incentives for promoting GB should be adapted to reflect the market transformation. Adapting incentives can positively influence stakeholders' motives, which in turn change stakeholders' behavioural intention towards GBs. Hence, this study aims to examine the parameters influencing the decision to adopt GB and to ascertain how incentive mechanisms promote the uptake of GB in South Africa.
Design/methodology/approach
Using a scoping literature review and a sequential mixed research method, primary data were acquired from GB experts in four South African provinces. In analysing the quantitative data, the factors were ranked hierarchically using the mean ranking technique and factor analysis was computed to identify the underlying GB incentives. The qualitative data were analysed using content analysis.
Findings
The results indicate that incentive payment from a utility energy efficiency programme, rebates and discounts relating to environmentally friendly materials and products and providing grants to homeowners and developers to go towards certification were the most essential monetary incentives for promoting GB. In the category of non-monetary incentives, recognition of consultant team members and developers and free marketing/good publicity were the most important incentives. The incentive mechanisms were subsequently categorised as “Economic incentives” and “Reward scheme and technical support”.
Research limitations/implications
This study was confined to four metropolitan areas in South Africa. Nevertheless, the outcomes have practical implications for GB projects in general and may serve as a good reference for other provinces in South Africa.
Originality/value
The findings of the study are a valuable resource for stakeholders such as the government, municipal assemblies, professional bodies and the Green Building Council of South Africa (GBCSA) in developing effective incentive mechanisms to promote GB adoption. This study adds to the body of knowledge relevant to GB incentivisation in South Africa.

Abstract
Purpose
The manufacturing industry is a well-known source of interventions adapted to solve problems in the construction industry. The use of Training-Within-Industry (TWI) is one such intervention adopted in the construction industry to solve the construction problem relating to occupational health and safety (OHS). The objectives of TWI are to help the industry to transfer knowledge and skills from management to the employees. Therefore, the purpose of this paper was to investigate whether TWI can reduce OHS problems by promoting “learning by doing” on construction sites.
Design/methodology/approach
A case-based-research method was used to investigate the reported OHS problems in the construction industry in South Africa. The data were quantitative and qualitative in nature; the questionnaire survey, semi-structured interview and focus group interview techniques were used to collect data in the study.
Findings
The findings provide a better understanding of the human contributions influencing the behaviour of people causing accidents on construction sites. The data show that construction project leaders struggle to promote “learning by doing” because of inappropriate behaviour, lack of communication and inadequate training provided to new workers on construction sites. Also, there is significant scope for TWI deployment in construction because of the inability of supervisors or management to promote “learning by doing” on construction sites.
Practical implications
Based on the research findings, it is discovered that OHS is a serious concern in the construction industry. Therefore, the adoption of learning by doing on a construction site would help to improve OHS outcome.
Originality/value
The study highlights the need to introduce TWI on construction sites to reduce human failure causing accidents. TWI could lead to improving the knowledge- and skills-transfer programmes for construction workers in favour of better safety performance.

Abstract
Purpose
Historically, a range of health and safety (H&S) challenges continue to be experienced. A two-day construction Industry 4.0 oriented H&S summit presented an opportunity to survey the delegates. The purpose of the study was to determine their perceptions, whether the presentations had an impact on their understanding and appreciation of the H&S challenges and the potential of Industry 4.0 technologies to improve H&S.
Design/methodology/approach
This paper reports on the findings emanating from a quantitative study that entailed the completion of a self-administered questionnaire survey conducted among delegates at the inception and closure of a two-day construction H&S summit.
Findings
The findings indicate that a range of H&S challenges are experienced in construction, Industry 4.0 technologies can contribute to addressing the H&S challenges and the presentations had an impact on their understanding and appreciation of the H&S challenges.
Research limitations/implications
The findings are primarily based upon perceptions in terms of the potential of Industry 4.0 technologies to contribute to addressing the H&S challenges.
Originality/value
This study reports on findings from one of a limited number of Industry 4.0 studies conducted in construction in South Africa. The findings indicate the level of awareness with respect to Industry 4.0 and the likelihood of the implementation of such technologies, as initially practitioners are likely to act based upon perceptions.

Abstract
Purpose
The purpose of this paper is to examine the predictable effect of economic and non-economic factors regarded as the most important to stimulate stakeholders’ behavioural intentions to adopt green building.
Design/methodology/approach
The primary data was collected from 106 green building accredited professionals in both the public and private sectors registered with the Green Building Council of South Africa. The data analysis techniques adopted include descriptive and inferential statistics, namely, factor analysis and logistic regression model (LRM).
Findings
The LRM results revealed five predictors and two control variables made a unique statistically significant contribution to the model. The strongest predictor to enhance the intention to adopt green building was a financial benefit (FB), recording an odds ratio of 9.1, which indicates that the likelihood to adopt is approximately 9.1 times more if FBs is evident.
Practical implications
It is anticipated that the most significant facilitators/enablers identified by built environment stakeholders will create an enabling environment to enhance the adoption of green building.
Originality/value
This research has contributed to the existing knowledge by developing a decision support model. The decision support model provides predictive indicators for clients, consultants and contractors to harness their resources and identify significant parameters to improve their decision-making in adopting green building.

Abstract
The New Partnership for Africa's Development (NEPAD) (2001) urges African leaders to take responsibility for revitalizing and extending the provision of education, technical training and health services with high priority given to tackling HIV/AIDS, TB and other communicable diseases. The International Labor Organization (ILO) and the World Health Organization (WHO) both agree that occupational health and safety in Africa needs strengthening. In support of this realization are the need to maintain and promote workers' health and working capacity. The fight against HIV/AIDS in the workplace is a continental priority. In the absence of any other definitive or similar study, this study aims to establish a valid baseline assessment of the levels of knowledge, types of attitudes, perceptions and beliefs of older construction workers in South Africa regarding HIV infection and AIDS. This paper reports only on findings concerning the level of knowledge and awareness of HIV/AIDS among older construction workers as determined during the first phase of an exploratory study commenced in August 2002. Older construction workers generally had acceptable levels of correct knowledge, perceptions and attitudes on most issues relative to the disease. However, their employers had not played a major contributory role. The study highlighted several areas where older workers either had incorrect and deficient knowledge and attitudes or demonstrated high levels of uncertainty.

Abstract
Purpose
The purpose of this paper is to present findings of research on the level of health and safety (H&S) awareness and implementation in Botswana's construction industry.
Design/methodology/approach
A questionnaire survey was conducted on construction projects to establish the level of awareness and implementation of construction H&S. Physical observations were also conducted on construction sites in order to relate questionnaire responses to what actually obtained on construction sites. The study was limited to Gaborone and the immediate surrounding areas.
Findings
Findings from the research reveal that the level of H&S awareness is low, H&S legislation is not complied with, the management of contractors is not committed to H&S implementation, there is a lack of H&S management systems, procedures, and protocol, and clients and designers do not participate in the implementation of H&S.
Originality/value
The importance of construction H&S has been recognised by various researchers. This paper provides an insight on the level of awareness and implementation of H&S in Botswana's construction industry and should be viewed in the context of an effort to improve H&S.

Abstract
Purpose
Construction is a complex process which requires the co‐ordination of and co‐operation between stakeholders. Most construction projects require the skills and services of various built environment disciplines and the effective integration of these skills determines the success of the project. However, built environment students continue to receive discipline‐based education. Construction shapes the built environment; therefore knowledge and understanding, to varying degrees of depth and complexity, of an array of subject areas are one required to suitably equip entrants into the built environment arena. Furthermore, the outdated education system is challenged by academics, built environment practitioners, and media reports. The purpose of this study is to question the suitability of built environment tertiary education in terms of current trends, technologies and practices.
Design/methodology/approach
A questionnaire developed from literature related to the diverse content, appropriateness, empowering effect, and delivery methods of built environment education, was used to survey built environment academics and postgraduate students. The questionnaire also aimed at determining the interconnectedness and cohesion between the five disciplines of architecture, quantity surveying, civil engineering, project management, and construction management.
Findings
There is a perceived need for both university of technology and university programmes, built environment tertiary education is relatively diverse in terms of content, there is a perceived need for a common first year and common subjects at other levels, and there is a trend towards perpetuation of traditional technologies, practices and systems within built environment education.
Originality/value
Certain subject areas should form an integral part of all built environment tertiary education programmes, in particular construction science and technology, management theory, information technology, and project management. This conclusion and the percentage responses relative to other subjects highlight the inadequacy of architecture and, to a lesser extent, civil engineering tertiary education.

Abstract
Purpose
The purpose of this paper is to consider the impact on architects of recently introduced Construction Regulations in South Africa.
Design/methodology/approach
Given the passing of the first anniversary of the promulgation of the Construction Regulations, a survey was conducted to determine the perceptions of member practices of the South African Institute of Architects.
Findings
Findings include: the traditional project parameters in the form of cost, quality, and time are still perceived to be substantially more important than health and safety (H&S); the manifestations of the impact of the Construction Regulations are wide spread – increased H&S awareness predominates among the manifestations, followed by increased consideration for H&S by most stakeholders, and H&S predominates in terms of the extent to which the Construction Regulations will impact on various project parameters.
Originality/value
The paper offers a valid argument for the inclusion of construction H&S to feature more prominently in architectural education and training programmes.
