The excellence in design and greater efficiencies (EDGE) certification system has seen a gradual adoption worldwide, with Ghana having six out of its eight certified green buildings bearing an EDGE certification. However, little is known about occupants’ satisfaction with the indoor environmental quality (IEQ) of EDGE-certified buildings. Therefore, the purpose of this study is to examine the satisfaction of occupants with the IEQ of an EDGE-certified building in Ghana by identifying their perceived performance of the indoor environment relative to their perceived importance.

A survey was conducted to evaluate the performance of 12 IEQ parameters with the occupants of an EDGE-certified office building. The survey results were evaluated using a gap analysis and both traditional and alternative Importance-Performance Analysis (IPA) matrices.

The findings revealed that noise level, temperature, cleanliness, sound privacy, air quality and humidity were IEQs that required the highest priority for improvement. Daylight and artificial lighting showed no appreciable performance gap. Space layout was adequately satisfied, whereas space size was overly satisfied. Visual privacy and outdoor view were found to require low priority of improvement.

This study contributes to the state-of-the-art of the IEQ of green buildings. It pioneers the research that seeks to examine the IEQ of EDGE-certified buildings. The gap analysis and the IPA were effective in prioritizing the IEQs for improvement action and provided a practical research framework that helped researchers examine the performance of green buildings, thereby giving valuable feedback to policymakers and building owners.

The absence of effective stakeholder engagement at the early planning and implementation stages impact projects negatively. However, the role of stakeholders in Sustainable Procurement (SP) is not well recognized and as such there is limited involvement of stakeholders in sustainable procurement of public (SPP) works. This research aims to examine the barriers to stakeholder engagement in SPP works.

A survey of 104 respondents from eight procurement entities of tertiary institutions in Ghana was undertaken and validated with seven procurement experts. After satisfying all the necessary tests of reliability of the survey instrument and sample size, the data was subjected to the Principal Component Analysis (PCA) to determine the critical barriers.

The study's results indicate that there are three cluster of barriers to stakeholder engagement in SPP works. They are organisational structures and knowledge driven factors, attitudinal and stakeholder fatigue and relational and information sharing processes.

This study offers relevant data for policy makers, organisations and local communities in establishing controls against barriers to stakeholder engagement. Furthermore, this research presents policy makers with recommendations to improve communication and organisational policies in enhancing stakeholder participation in SPP works in Ghana and other developing countries.

Although studies on SP has increased with time, issues such as obstacles to stakeholder engagement in SP remain unexplored. Empirical data presented in this study bridges the gap that exists on the barriers of stakeholder engagement in SPP works in the Ghana Construction Industry.

Capillary rise of water in buildings has been an issue of concern among past and present researchers. Despite the research efforts devoted to the proper elimination of the problem in masonry construction, it still remains a challenge that needs to be addressed. The purpose of this paper is to explore treatment mechanisms that can be used to prevent rising damp in new building infrastructure.

In total, 14 test walls are constructed, conditioned, subjected to various treatments and monitored for four years. The treatments applied to the walls include the use of polyethylene damp proof courses, damp proof coatings and dense concrete bases. The walls are then monitored with reference to the two climate seasons in Ghana.

The results highlight that rising damp is present, as suggested by the constant increase and decrease in the height of the water levels in the walls during the rainy and dry seasons, respectively. The findings further reveal that within the four-year period, the walls treated with the damp proof coatings, together with those with the dense concrete bases performed better than those treated with the polyethylene damp proof courses.

The economic and commercial impact of these preventive mechanisms were not considered in this study. A future research can be directed at these issues.

The proposed treatment mechanisms highlight the effectiveness of some treatments applied to walls to prevent the capillary rise of water from the ground into the superstructure.

Building regulations, especially in Ghana and other tropical settings should be amended to include ways to prevent rising damp phenomena by including effective methods against rising damp during the building design or construction.

Series of studies worldwide have been conducted in laboratories to simulate the capillary rise of water in walls of buildings. This is among the few studies that look at how water rises from actual ground conditions into the walls of buildings.

This study examines the level of awareness and practice of the principles of circular economy (CE) among built environment (BE) professionals in Ghana.

A structured questionnaire survey was used to solicit the views of 162 BE professionals working in construction, consulting and developer firms on the issue under investigation. Data were analysed through descriptive and inferential analysis.

The findings revealed that the BE professionals possessed moderate awareness of the six CE principles (i.e. repair, recycle, reuse, renewable energy usage, reduce and redesign) examined. The findings further revealed that only two out of the six principles (i.e. repair and reuse) received some moderate level of practice among the professionals.

Practically, the findings would be relevant to government, policymakers, researchers and other construction professionals. For the government and policymakers, these findings would inform them on the laws and policies to enact to increase awareness and practice of CE principles. For researchers, these findings will assist in exploring gaps for further studies. For the construction professionals, the findings would inform them of the need to step up measures to practice the various principles of CE in their firms adequately.

This study provides insights into an under-investigated topic in the construction industry worldwide. It offers new and additional insights into the current state-of-the-art practice of CE principles among BE professionals.

The majority of the literature on green buildings in Ghana focuses on environmental benefits, innovative designs, construction technologies and project management techniques. However, little is known about how such facilities are financed. This issue creates potential knowledge gaps, one of which this study aims to address. This study examines the key drivers for green building project financing in Ghana.

The study uses an explanatory sequential design with an initial quantitative instrument phase, followed by a qualitative data collection phase. An extensive critical comparative review of the literature resulted in the identification of eight potential drivers. One hundred and twenty-seven questionnaire responses based upon these drivers from the Ghanaian construction industry were received. Data were coded with SPSS v22, analysed descriptively (mean, standard deviation and standard error) and via inferential analysis (One Way ANOVA and One-Sample t-Test). These data were then validated through semi-structured interviews with ten industry professionals within the Ghana Green Building Council. Data obtained from the semi-structured validation interviews were analysed through the side-by-side comparison of the qualitative data with the quantitative data.

Though all eight drivers are important, the five key drivers for the Ghanian construction industry were identified as, in order of importance, “high return on investment”, “emerging business opportunity”, “ethical investment”, “conservation of resources” and “mandatory regulations, standards, and policies”. The interviewees agreed to and confirmed the importance of these identified drivers for green building project financing from validating the survey's key findings.

Key limitations of this study are the restrictions regarding the geographical location of the collected data (i.e. Kumasi and Accra); timing of the study and sample size (i.e. the COVID-19 pandemic making it difficult to obtain adequate data).

Though this study was conducted in Ghana, its implications could be useful to researchers, policymakers, stakeholders and practitioners in wider sub-Saharan Africa. For instance, financial institutions can invest in green buildings to expand their green construction and mortgage finance products to build higher value and lower risk portfolios. The findings from this study can provide investors with the enhanced certainty needed to help guide and inform their investment decisions, i.e. what to invest in, and when, by how much and how a scheme being “green” may influence their rate of return. Also, for building developers, it will give them a clearer understanding of the business case for green buildings and how to differentiate themselves in the market to grow their businesses.

This study's findings provide insights into an under-investigated topic in Ghana and offer new and additional information and insights to the current state-of-the-art on the factors that drive green building project financing.

The purpose of this paper is to ascertain the interaction effects among organizational citizenship behavior (OCB), work overload (WO) and employees’ performance in the Ghanaian construction industry, thus identifying the thin boundary between advocating OCB and avoiding WO in attempt to increase higher employee performance.

Using a quantitative research method, three hypotheses were tested. The views of 86 project teams were elicited using a structured questionnaire, and linear regression was utilized to validate the hypotheses.

The study proved that OCBs positively affect employee performance in the construction industry. The results implied that increased work load on employees do not increase their productivity levels, but adversely increase the unconsiderable effects of employees’ work lives. In addition, WO played the role of homologizing moderation in the relationship between OCB and employee performance.

The findings suggest that there is a considerable effect of WO on overall employee performance in the construction industry; thus, there is a need for stakeholders to address this issue for performance improvement.

The application and investigation of these issues have dominated the banking industry but lacked in the construction industry. The current study therefore provides useful insight into the interaction effects among organizational citizenship behavior, WO and employees’ performance in the Ghanaian construction industry.

The construction industry plays an important role in the achievement of the 11th and 15th of the Sustainable Development Goals. Efforts have been made by most developing and developed economies toward the achievement of these goals. Despite the efforts being made by the construction industry toward the achievement of these goals, there are still barriers that prevent built environment consultants from advancing environmental sustainability (ES) of construction projects. The purpose of this paper is to identify barriers to ES of construction projects.

An extensive literature review on barriers to the adoption of ES was conducted and face-to-face semi-structured interviews of purposively selected built environment consultants in Ghana were carried out. Thematic template analysis of qualitative data was conducted.

The key findings from the study include perceived initial costs, lack of knowledge on ES, technological difficulties, external pressures in adopting ES practices and environmental conditions in developing countries.

The outputs of this study offer strategies which are very significant to the construction industry in embracing ES. Further, the findings contribute to knowledge on achieving the sustainable development agenda.

This study draws on neoclassical and behavioural economics theories to provide an empirical insight into the effect of knowledge, costs, and social norms on damp-proofing residential buildings in Ghana.

This study used the quantitative approach involving survey data. A sample size of 242 participants was involved in the study. Applying principal component analysis on the responses from the participants, an index for damp-proofing, cost, knowledge, and social norms was derived. After generating the indexes, the ordinary least squares (OLS) regression was applied to estimate the impact of knowledge, costs, and social norms on damp-proofing.

The results from the OLS regression revealed that knowledge has a significant positive effect on damp-proofing while costs and social norms have significant negative effect on damp-proofing in Ghana. This study, therefore, concludes that although neoclassical economic factors such as knowledge and cost affect behaviour (damp-proofing), behavioural factors such as social norms also matter.

The outcome of this study calls for policymakers to consider putting in place measures that increase knowledge and promote the use of damp-proofing techniques during the construction of buildings. In addition, the study calls for scholars to partake in collaborative research amongst disciplines such as economics, psychology, and the construction industry in order to provide more innovative solutions, the key of which is finding innovative ways to damp proof buildings.

This study is original in its context as it draws on neoclassical and behavioural economics theories to provide an empirical insight into the effect of knowledge, costs, and social norms on damp-proofing of residential buildings in Ghana. This is an area that has received less attention in the areas of building biology and building pathology globally.

Circular economy (CE) is guided by principles, the key being the R-framework. All R-frameworks have a hierarchy. Although several studies have prioritized these principles, there is still an urgent call for country-specific prioritization. This study prioritized circular economy (CE) principles among Ghana's built environment (BE) professionals.

An explanatory sequential mixed methods approach was adopted. Six principles of CE were identified through a review of related literature and incorporated into a questionnaire. In total, 162 questionnaire responses were received. The quantitative data were analyzed through descriptive and inferential analyses. The data were further validated via semi-structured interviews with eight interviewees of different professional backgrounds in the BE.

The findings revealed that BE professionals in Ghana highly perceived CE principles as important. The findings further revealed the order of prioritization of the CE principles as follows: (1) recycle, (2) reuse, (3) repair/remanufacture, (4) renewable energy usage, (5) redesign and (6) reduce. To further elaborate on these prioritized principles via the qualitative phase, the interviewees agreed to and confirmed the importance of the identified principles through their verbatim comments.

Although there is a growing interest in research regarding CE in the Ghanaian construction industry, its principles have yet to be prioritized and ranked by professionals in the Ghanaian construction industry. This study unearths why, in terms of prioritization of the CE principles, the construction industry in Ghana does not follow the well-known hierarchy (i.e. reduce, reuse and recycle) in the order of high to low level of circularity.

This study explores the utilization of simulation tools for building performance assessments among design professionals in Ghana.

A quantitative approach was used to obtain responses from 104 design professionals in Ghana through a structured questionnaire. The questionnaire was generated through a critical review of the related literature on the subject matter. Data from respondents were analyzed through descriptive and inferential statistics.

Results from the analysis indicated that design professionals in Ghana possessed a low level of awareness of the simulation tools used for building performance assessments. Subsequently, the findings also revealed that the design professionals' level of usage of the simulation tools was low.

Practically, the establishment of this study informs design stakeholders, educational institutions and researchers in Ghana. For design professionals, these findings will focus on enhancing their use of simulation tools for evaluating building performance in Ghana. For educational institutions, these findings will enable them to implement the necessary strategies for incorporating the concept of building performance simulation into their curriculum in order to boost awareness and utilization. Finally, researchers will also use the study's findings to identify any research gaps for future studies.

The findings from this study pioneer knowledge on an under-investigated topic within the Ghanaian construction industry. It also provides insight into the developing state-of-the-art technology employed in the built environment.
