Abstract

This literature review examines the progress, challenges, and opportunities in adopting sustainable construction practices in Nigeria over the past two decades. Significant advancements have been made, particularly in the use of energy-efficient materials and Building Information Modeling (BIM), which have improved project efficiency and sustainability. Policy frameworks have evolved to support these technological innovations, but widespread adoption of sustainable practices is still hindered by economic constraints, cultural resistance, and regulatory gaps. Economic challenges, especially the high costs of sustainable technologies, are major obstacles, worsened by limited financial incentives and economic instability. Cultural factors, such as a preference for traditional construction methods, and inconsistent enforcement of building codes further complicate efforts to promote sustainability. Despite these barriers, there is growing awareness of the need to integrate sustainability into the construction sector, driven by both global environmental concerns and local development needs. The review also highlights its limitations, including a reliance on published academic literature, which may not fully capture recent industry trends or local realities. Excluding grey literature and non-English publications may omit important regional perspectives. The review recommends future research on detailed economic analyses of sustainable technologies, exploring the integration of traditional and modern practices, and comparative studies with similar countries.

Abstract

This study investigates the impact of energy-efficient technologies (EETs) on the Nigerian construction sector, focusing on their benefits, barriers to adoption, and sustainability implications. Using a mixed-methods approach, data were collected through structured surveys, semi-structured interviews, and case studies involving construction professionals and stakeholders. The findings reveal that EETs offer significant economic, environmental, and social benefits, including reduced operational costs, lower energy consumption, and improved occupant comfort. However, their adoption in Nigeria is hindered by high upfront costs, lack of technical expertise, insufficient awareness, and weak regulatory frameworks. These challenges align with findings from other developing countries, underscoring the need for targeted interventions. The study also highlights the potential of EETs to contribute to sustainable development by reducing greenhouse gas emissions and supporting the achievement of the United Nations Sustainable Development Goals (SDGs). Case studies of successful projects in Nigeria provide valuable insights into best practices, emphasizing the importance of strong leadership, stakeholder collaboration, and access to financing. Based on the findings, the study recommends policy interventions, capacity-building initiatives, public awareness campaigns, and regulatory reforms to promote the adoption of EETs. Future research should explore innovative financing mechanisms, the role of digital technologies, and the impact of occupant behavior on energy efficiency. This study contributes to the growing body of literature on sustainable construction practices and provides a foundation for further investigations into the adoption and impact of EETs in Nigeria and similar contexts.

Abstract

The construction industry is a major driver of economic growth but remains one of the largest contributors to environmental degradation, resource depletion, and carbon emissions. This study examines the key determinants influencing the adoption of sustainable construction practices in Nigeria, focusing on environmental, economic, social, policy, and technological factors. A cross-sectional survey was conducted with 400 construction professionals, and data were analysed using Structural Equation Modelling (SEM) to establish causal relationships among the identified variables. The findings reveal that policy regulation (β = 0.37, p < 0.001), environmental factors (β = 0.42, p < 0.001), and climate change awareness (β = 0.38, p < 0.001) are the strongest predictors of sustainability adoption. The study also establishes that stakeholder collaboration mediates the relationship between policy regulation and sustainability adoption, while market demand for green buildings moderates the influence of economic feasibility. Despite increasing awareness of the benefits of sustainability, barriers such as high initial costs, weak regulatory enforcement, limited access to green financing, and slow technological adoption continue to hinder widespread implementation. The study underscores the need for robust policy enforcement, financial incentives, capacity-building programs, and the integration of smart construction technologies to drive sustainability adoption in Nigeria’s built environment. The findings provide valuable insights for policymakers, industry practitioners, and researchers, offering a strategic framework to accelerate the transition toward climate-resilient, energy-efficient, and economically viable construction practices.
