Abstract

Purpose

The use of air-conditioners (ACs) is on the increase in the developing world, with exacerbating compounding effect on carbon footprints. With this development, there is the expectation that developing countries would begin to appreciate and understand occupant behaviours in the use of ACs towards combating climate change, especially as building energy consumption is heavily influenced by the behaviour of its occupants. This study aims to identify occupant behaviours that leads to efficient use of ACs in public buildings so that these can be factored into developing guidelines for improving energy efficiency in buildings.

Design/methodology/approach

Drawing on the theory of planned behaviour (TPB), survey questionnaire was used to collect data in office buildings in Kumasi, Ghana. Partial least squares–structural equation modelling (PLS-SEM) analysis was employed for the analysis.

Findings

Switching on fan(s) as alternative to ACs has a path coefficient of 0.527, suggesting that it will have the most positive impact on energy consumption as far as AC use is concerned. The second occupant behaviour with a positive impact on energy consumption for AC use is opening windows for natural ventilation accounting for 0.351 significant path coefficient. Wearing of light or heavy clothing as a means of conserving energy achieved 0.174 impact coefficient while occupant behaviour of switching off ACs when leaving the room came last in the ranking, with an impact coefficient of 0.146. TBP is validated in this model, given that all the four occupant behaviours had their perceived behavioural control (PBC) having less impact on the behaviour compared to the behavioural attitude (BA) and the subjective norm (SN).

Research limitations/implications

This research focused on public buildings used as offices, and the findings may not be applicable to private company buildings and also residential properties. Given that Ghana and, for that matter, many developing countries rely heavily on thermal plant for electricity generation, the climate change implications of the findings are discussed.

Practical implications

It is recommended that behaviours of occupants should be considered and factored in building energy predictions to bridge the energy performance gap. Subsequently, project managers, designers and energy consultants are encouraged to provide fans and openable windows in offices, even if there is going to be an air-conditioning provisions.

Originality/value

Originality emanates from the paper being at the forefront of helping to understand occupants' behaviour in the use ACs and associated climate change implications in a developing country context. One of the new variables introduced, switching on fans as an alternative to ACs, achieved the highest path coefficient and has important implication for occupant behaviour in the use of ACs in the literature.

Abstract

Purpose

Workforce diversity is essential for success from the perspectives of economic development and intellectual property. However, the construction industry is losing out on these gains due to the low diversity among them. The study aims to identify challenges impeding workforce diversity in construction literature through a mixed review approach.

Design/methodology/approach

The study desk reviewed 188 relevant construction peer-reviewed articles and conference papers with no restrictions on the time range. The study adopted the mixed methodology review approach through bibliometric and systematic content analyses.

Findings

The study identified 67 challenges and further classified them into 4 broad categories. These were industry-related, organisational-, personal or attitudinal- and health-related challenges. Organisational challenges were the most prevalent challenges of diversity uptake in the construction industry. The publications' most influential sources, countries/regions and annual trends were also discussed.

Practical implications

Classifying the challenges hindering diversity contributes to the existing knowledge base. The framework's interrelationships among categorised barriers will enable construction professionals to make informed decisions in promoting diversity in the industry.

Originality/value

This study has a broad geographical reach, allowing the findings to be widely applicable to the diverse practice of the worldwide construction sector.

Abstract

Purpose

While previous studies have focused on identifying management control (MC) mechanisms in international construction joint ventures (ICJVs), the impacts of such MC mechanisms on the performance of ICJVs remain largely unknown. This study aims to investigate the impacts of MC mechanisms on the performance of ICJVs hosted in the developing country of Ghana.

Design/methodology/approach

Through a comprehensive review of the literature, a theoretical model was developed, and data were collected through a questionnaire survey with 190 project managers composed of Ghanaians/locals and their foreign partners of ICJVs. The data were analyzed using partial least squares structural equation modeling.

Findings

Results showed that both personnel and support and training control mechanisms have a positive and significant impact on project and company/partner performance. Surprisingly, insignificant and negative impacts exist between both mechanisms and socioenvironmental and company/partner performance from the local partners' view, respectively; the reverse is rather true from the foreign partners' perspective.

Practical implications

This study contributes to the ICJV body of knowledge by analyzing the impacts of MC mechanisms on the ICJVs’ performance, enabling ICJVs frontliners (i.e. top managers) and project managers to better enhance their control structures and the ICJVs’ performance.

Originality/value

This is arguably the first study to take the bipartite perspective rather than the unilateral view of studying the impacts of MC mechanisms on the performance of ICJVs.

Abstract

Purpose

International construction joint ventures (ICJVs) implementation is plagued with several barriers, full understanding of which is still lacking due to a lack of an in-depth exploration of them, particularly in developing countries. To fill this knowledge gap, this study aims to investigate the critical barriers to the success of ICJVs hosted in developing countries by examining the Ghanaian case.

Design/methodology/approach

This study builds on a previous study that identified 37 barriers factors to ICJVs success via a systematic literature review. Through expert interviews, 34 potential barriers were identified, and a two-round survey was conducted with 84 ICJVs practitioners in Ghana. The data collected was analyzed using the combination of a multidimensional fuzzy logic method and confirmatory factor analysis.

Findings

Results showed that 22 barriers were critical. The top five most critical barriers were “lack of preparedness to accept company philosophy,” “competing objectives,” “opportunistic behavior of parties,” “conflicts” and “lack of management control.” Furthermore, the results uncovered and confirmed five significant underlying components for the 22 critical barriers, namely, organizational-related, cultural-related, knowledge-related, individual-related and logistics-related barriers.

Practical implications

The findings could be useful to ICJVs practitioners and policymakers in developing suitable strategies for the successful implementation of ICJVs. Further, foreign firms aiming to execute and promote ICJVs in Ghana could have prior knowledge of the critical barriers and prepare for them.

Originality/value

This study empirically analyzed the individual levels of barriers criticalities in ICJVs context and from a specific-country perspective – the developing country of Ghana – rather than in the context of construction joint ventures and from a cross-country perspective in extant studies.
