The high consumption of energy by buildings may have enhanced land degradation, flooding, air pollution and many other hazardous environmental issues. However, green practices in buildings have been proved as one of the successful technologies to mitigate these issues. Past studies have shown lax green practices in Nigerian buildings. Concerning public hospital buildings, this is yet to be explored. Therefore, this paper aims to investigate the barriers to green practices and proffer possible policy solutions to promote hospital green buildings.

In attaining these objectives, the view of hospital building contractors, design team, hospital management and policymakers in the relevant ministries/agencies was engaged via virtual interviews. The collated data were analysed and presented in the thematic pattern.

Findings show that green building construction is extremely low in Nigeria, but the worst hit is the health-care buildings across the states. Government/policy-related, organisational/leadership-related, financial-related, technical-related, design team-related and stakeholders’ behaviour-related barriers emerged as the main six themes of barriers affecting public hospital green buildings implementation initiatives. Findings show that proffering possible policies to addressing these barriers may improve public hospital green construction across the states.

This paper is limited to barriers to green buildings implementation in public hospitals in Nigeria, and data collection was through virtual interviews but does not affect the strength of the findings. Thus, this paper suggests that the sub-themes and variables/items that emerged from the collated data as presented in Figure 1 can be further developed quantitatively via questionnaire survey to validate and improve the reliability of results from this paper.

As part of this study’s implications, suggestions from this paper will stir up policymakers’ decisions, to be tailored towards achieving green buildings implementation initiatives in Nigerian public hospitals.

To the best of the authors’ knowledge, this paper is probably the first that attempted to investigate the barriers to green buildings implementation in public hospitals in Nigeria.

This study aims to examine facility management practices in the Nigerian healthcare sector, exploring approaches and identifying challenges facing effective healthcare facilities management. The purpose is to contribute to the development of a framework for enhancing healthcare facility management efficiency in Nigeria.

The study employs a sequential in-depth exploratory qualitative research approach. The data collection involved conducting semi-structured interviews with 15 facility managers from diverse healthcare organisations in Nigeria. The qualitative data collected were analysed using thematic analysis.

The study reveals scheduled, unscheduled and mixed approaches as the three facility management approaches used in Nigeria. It also substantiates the underdeveloped nature of facility management in Nigeria's healthcare sector, exacerbated by challenges such as socioeconomic, operational, technological and regulatory challenges.

The study uncovers systemic issues affecting have attainment of Sustainable Development Goal 3 (Good Health and Well-being) and advocates for a comprehensive approach to enhance healthcare infrastructure, contributing to improved health outcomes and sustainable development.

This research uniquely uncovers the hidden challenges facing effective healthcare facility management in Nigeria, providing a foundation for stakeholders to formulate solutions and rescue the struggling state of healthcare facilities in the country.

The dearth of green standards (GS) in sub-Saharan Africa is alarming and the green cost premiums (GCP) in seeking certification in emerging markets are scanty. This paper studied the Building Energy-Efficiency Code of Nigeria (BEEC) and estimated the potential GCPs associated with the various energy-efficiency ratings.

The study retrofitted 150 conventional residential bungalow and maisonette buildings using BEEC's energy-efficiency interventions and performed analytical estimating of the retrofitted designs. The mean cost premium associated with each energy-efficiency intervention is presented as well as their financial benefits and payback periods. The benefits are achievable financial-savings due to a reduction in energy consumption and savings in electricity payment estimated from the average energy demands of each building. An independent t-test was further conducted to determine the cost differential between energy-efficient design (ED) and conventional design over a five-year period.

The potential GCPs and their payback periods are actually less than feared. The study showed that less than 5% and 21% extra funding would be required to achieve 1 to 4-Star and 5-Star energy-efficiency ratings involving passive design interventions and photovoltaic systems. Passive and active design interventions produced a financial savings of $8.08/m² in electricity payment and $2.84/m² per annum in energy consumption reduction. The financial-savings ($10.92/m²) was objective to pay-off the GCPs in less than four years. The independent t-test analysis showed the cost of ED is more economical after four years into the project lifecycle.

The research provides cost benchmarks for navigating cost planning and budgetary decisions during ED implementation and births a departure point for advancing energy-efficient construction in developing markets from the rational economic decision perspective.

Research on measures to strengthen the implementation of indoor environmental quality (IEQ) principles has been scarce in developing countries such as Nigeria. Hence, this study sought to identify and assess the crucial measures for encouraging the adoption of IEQ principles in the Nigerian construction industry, specifically from the viewpoint of quantity surveyors.

To accomplish this objective, a quantitative research methodology was employed, utilizing a well-structured questionnaire distributed to quantity surveying (QS) firms in Nigeria. The collected data were examined using a range of statistical techniques such as frequencies, percentages, mean item scores (MISs), the Kruskal–Wallis test and exploratory factor analysis.

The top five ranked measures were as follows: offer financial incentives and tax breaks, develop educational materials and resources, establish clear and accessible reporting mechanisms, develop awards and recognition programs and provide advocacy and awareness campaigns. Factor analysis led to the categorization of the identified measures into four primary clusters: education and training, policy and regulation, incentivization and recognition and collaboration and networking. Consequently, these clusters were renamed the EPIC (Education and training, Policy and regulation, Incentivization and recognition and Collaboration and networking) framework, with each first letter representing a significant measure for fostering the adoption of IEQ principles.

Consequently, this study offers a robust foundation for understanding and implementing measures to enhance the adoption of IEQ principles within the Nigerian construction industry, ultimately benefiting stakeholders and improving the quality of built environments.

The EPIC framework designed in this study offers valuable insights for policymakers, construction industry professionals and other stakeholders interested in promoting IEQ principles, which can potentially lead to healthier, more comfortable and more sustainable built environments in Nigeria and beyond.

The purpose of this study is to conduct a systematic review on encumbrances facing the implementation of GBP in selected African countries. Green building practices (GBP) implementation is germane and promotes the development of a green environment and buildings. Many studies have been conducted on the encumbrances faced with GBP implementation, especially in developing countries. But evidence of a comprehensive study that investigates and analyses these hindrances from different developing countries is missing. Therefore, a systematic review is conducted systematically reviewing the current literature on encumbrances facing the implementation of GBP in selected African countries. Also, the study proffers possible drivers for stakeholders to promote GBP in African countries.

A total of 38 published papers were identified from the Web of Science, Scopus database and supported with materials from Google Scholar related to Africa’s GBP. The continent was divided into five regions, and each region covered three countries.

Two themes emerged from the analysed review – encumbrances facing GBP implementation and possible drivers for stakeholders to promote GBP in African countries. A total of 18 encumbrances and 18 drivers were identified from the analysed literature and grouped into 6 sub-themes.

Current empirical articles were reviewed to suggest the drivers for stakeholders to promote GBP that emerged from this paper. Thus, to enrich the results from this paper, primary source data of regional studies of GBP in Africa’s context should be carried out via the mixed-methods design.

A total of 18 drivers were identified for stakeholders to promote GBP in Africa and form part of the paper’s implications. Also, the paper findings would serve as a treasured suggestion for the stakeholders (policymakers, construction practitioners, clients and academics) who are fascinated by the promotion of GBP across African nations.

This is possibly the foremost analysed systematic review study on GBP implementation in Africa. Therefore, it fills the theoretical gap and proffers possible drivers for stakeholders to promote GBP in the African context.

Sustainable urbanism is the study of both cities and the practices to build them, which focusses on promoting their long-term viability by reducing consumption, waste and harmful impacts on people and place while enhancing the overall well-being of both people and place. This paper analyses the implications of adopting sustainable urbanism principles and developing resilient places with Abuja as the area of focus to tackle the highlighted issues.

The paper is based on qualitative research which is centred on an extensive literature review and archival retrieval of historical documents. This includes the emergence of urbanism, sustainable urbanism definition and current issues surrounding its adaptation. The paper also focusses on a case study area in the capital city of Abuja, Nigeria which is currently undergoing massive urban development. Interviews are conducted with academics (13), practitioners (12) and government officials (10) making a total of 35 participants.

The main findings will create an understanding of the definition of sustainability and sustainable urbanism with a special focus on Abuja city. It was realised from the interviews that sustainable urbanism in broad terms encompasses economic, social, and environmental sustainability, and that these dimensions vary across different contexts even in the developing world. Also, sustainability can be achieved through deploying the right combination of measures, policies, assessment tools, sustainability assessment, good governance, and training/education and incentives.

By reviewing the selected studies which explore a wide range of disciplines and research areas, and conducting this qualitative research, this paper shares insights into how sustainability and sustainability urbanism can be achieved in the development of urban spaces in Abuja environs.

The construction industry in developed countries is witnessing a paradigm shift towards modular construction methods, driven by the need for efficiency, sustainability, and cost-effectiveness. However, the realization of these benefits in the context of developing countries is hindered by numerous barriers. Against this backdrop, this study seeks to contribute insights into the barriers hindering the adoption of modular construction in developing countries, specifically Nigeria, and further formulate effective strategies.

A thorough review of existing literature was conducted to identify the multifaceted barriers hindering the adoption of modular construction and the corresponding strategies. Subsequently, a panel of 13 experts were invited to utilize the Fuzzy Analytic Hierarchy Process (FAHP) approach to systematically evaluate these barriers based on their impact. Furthermore, the experts implored the Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS) approach to select and prioritize the most suitable strategies to mitigate these barriers.

The study revealed that the most critical barriers to modular construction are Client resistance to change and innovation, Limited experience in module installation, and Transportation constraints. Additionally, the study prioritizes 13 strategies, with the Development of effective guidelines, standards, and policies ranked highest. The insights from the ranking using the FAHP and TOPSIS approach were adopted to develop a framework for modular implementation in developing countries.

This study is limited to Nigeria due to its status as the country with the highest Gross Domestic Product (GDP) in Africa, and it is considered a suitable representation of the region as most of the countries in Africa are categorized as developing nations.

By highlighting the most critical barriers and prioritizing effective strategies, the study provides actionable insights for overcoming obstacles to modular construction adoption. Decision-makers can use this information to develop targeted policies and training programs to promote the adoption of modular construction in developing countries.

The research provides valuable insights by not only identifying critical barriers but also presenting prioritized strategies, distinguishing itself from previous studies, and establishing itself as a novel resource for developing countries. This adopt a novel hybrid MCDM approach for modular construction in developing countries such as Nigeria which can serve as reference point to other developing countries seeking to adopt modular construction and leverage its numerous benefits.

Funding infrastructural facilities of higher institutions, especially in some developing nations such as Nigeria, that is under-funded, is a challenge in the current era. Private organisations participation in infrastructure development via a proposed expanded corporate social responsibility (ECSR) may enhance infrastructural facilities provision. There is a paucity of literature regarding ECSR, a form of infrastructure tax relief providing infrastructural facilities for higher institutions. Therefore, the study investigated the role of private organisations via a proposed ECSR in the provision of infrastructure and proffer ways to enhance higher institutions' infrastructure development delivery in Nigeria.

The study data were collated via face-to-face interviews and observation of existing buildings. From the six geo-political zones, two higher institutions each were selected for a good representation across Nigeria. Saturation was achieved with 26 participants interviewed. The emerged three main themes were analysed via thematic analysis.

Findings show inadequate infrastructure development in Nigerian higher institutions. Lack of policy and institutional framework, lax governance, level of transparency, and corruption, emerged as the key issues that may hinder private organisations from participating in public higher institutions infrastructure development delivery in Nigeria via ECSR. Others are lack of autonomy, inadequate planning, high level of impunity, political affiliation, poor management, and access to funding. The study proffers some recommendations based on these findings.

This research is restricted to the role of private organisations via ECSR in infrastructure development (buildings) in Nigeria's public higher institutions. Future study is needed to validate the proposed ECSR framework in developing countries for the provision of buildings for higher institutions in their host communities.

The paper will advance the philosophy of corporate social responsibility to the provision of building facilities in host communities' higher institutions by private companies through tax relief and supported by a proposed Presidential Executive Order.

The proposed ECSR framework can be used to improve building facilities in Nigeria's higher institutions. This may assist and stir up policymakers to explore the proposed model and back up with an established policy such as infrastructure tax relief (ITR) for implementation.

The aim of the chapter is to compare Public–Private Partnership (PPP) healthcare investments in developed countries with those in emerging economies, analysing the sustainability issues of health-led growth. Healthcare PPP best practices in developed nations represent a template that catching-up economies may follow with local adaptations. A comparison starts from the UK case and then examines the Turkish experience as an ideal bridge between advanced and developing countries. Healthcare investments are a primary social infrastructure, with a deep impact on poverty alleviation. Demand for the infrastructure necessary to provide healthcare services has increased substantially in developing and emerging economies due to rapid economic growth, industrialization and urbanization, while public supply is limited by budget constraints. PPP best practices provide a global benchmark (World bank, 2015b). Integrated supply and value chains and management of viability milestone improve healthcare PPP sustainability and bankability. Different legal frameworks and funding issues are not thoroughly investigated. Careful customization and local fine-tuning of best practices require further scrutiny. Homogenization of best practices improves comparison of different projects, fostering competition and easing cross-border investments, accompanied by knowledge transfer, sharing and consequent value co-creation. Best practices improve value for money, bankability and resilience of PPP investments, with potential benefits for healthcare services and quality of life. This chapter makes an innovative and comprehensive comparison of healthcare PPP projects worldwide, looking for a common denominator of value-enhancing rules and resilient pro-growth strategies.
