PurposeDeveloping countries in sub-Saharan Africa are faced with significant challenges as the economies continue to emerge. There is a huge infrastructural demand and various efforts to step up supply. Whilst stepping up the supply, the environmental concerns of these supplies require a lot of attention. With the need to reduce the environmental impact of buildings whilst promoting a green infrastructure, various studies have explored the obstacles to green building technology adoption. This study explores the impediments to the development of the green building market in sub-Saharan Africa.Design/methodology/approachUsing building consultants as the unit of analysis, this study explores the impediments using a structured survey questionnaire. The study area is Ghana, an emerging country in sub-Saharan Africa.FindingsKey impediments to the development of the market is lack of awareness, lack of education and lack of fiscal incentives. The analysis shows that all the variables identified are significant in impeding the growth of the market. The results suggest that within the domain of developing countries, environmental issues may not be of immediate concern as economic issues take centre stage. For sustainability of the environment, it is unequivocal that dissemination of knowledge to key stakeholders be done.Practical implicationsAcademic institutions and professional bodies have a pivotal role to play in raising awareness of green buildings. Governmental support such as various structures should be put in place to build up the local capacity of firms not only to compete with foreign counterparts but also to ensure innovative delivery of green buildings.Originality/valueThe paper presents contextual realities on the green market restrictions within developing countries in sub-Saharan Africa through a deeper understanding of market barriers and recommends pathways for stakeholders.
Purpose -The purpose of this paper is to empirically study the factors that facilitate adoption of building information modelling (BIM) among quantity surveyors (QSs) using the unified theory of acceptance and use of technology (UTAUT).Design/methodology/approach -Using a quantitative approach, factors identified in the UTAUT are examined. The empirical investigation has been conducted using survey questionnaire. The data set has been obtained from 73 practicing QSs in Ghana.Findings -The results indicated a significant positive impact of effort expectancy, facilitation conditions and hedonic motivation towards BIM adoption. Surprisingly social influence and performance expectancy have a negative impact on BIM adoption.Practical implications -The structures uncovered in the study show that not all UTAUT factors are applicable within the study area. The findings provide a good backdrop in the development of policy and a roadmap for BIM implementation in Ghana.Originality/value -The original contribution and value of the paper is the use of UTAUT2 to provide empirical evidence on factors that facilitate BIM adoption in Ghana amongst QSs.
Purpose Building information modelling (BIM) and augmented reality (AR) are unique technologies in the digitalized construction industry. In spite of the numerous benefits of BIM-AR, its adoption has been at a relatively slow pace. The purpose of this study is to investigate how the factors within technology–organization–environment (TOE) framework influence the adoption of BIM-AR in the context of construction companies in a developing country. Design/methodology/approach By using a mainly deductive quantitative design, survey data were collected from senior management of built environment companies in Ghana using questionnaires. The study adopted a mixture of both purposive and snowball sampling approaches. Partial least squares structural equation modelling was used to analyse how the factors within the TOE framework explain BIM-AR adoption in Ghana. Findings Findings from the study show that the top three factors within the TOE framework that facilitate the adoption of BIM-AR include ICT infrastructure within construction firms; the size of the construction firm, which may influence the financial capacity to accommodate BIM-AR; and competitive pressure. The inhibitors of BIM-AR at the company level included external support and trading partners’ readiness. Research limitations/implications Implicit is that the significant factors will be useful to policymakers and companies in developing programs that appeal to non-adopters to aid in mitigating their challenges and further enhance BIM-AR adoption. Originality/value The value of this paper has been the use of the theoretical framework TOE to explain the adoption factors of BIM-AR in the Ghanaian construction industry. The originality of the paper is further anchored in consideration of BIM-AR, which is quite nascent in emerging countries.
Purpose -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. Design/methodology/approach -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. Findings -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. Originality/value -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.
