Integrated Sustainability Framework for the Adoption of Engineered Wood Products in the Nigerian Construction Industry: Evidence from Enugu State, Nigeria

The global construction industry is a massive consumer of the planet's resources, using vast amounts of water, energy, and raw materials while generating a significant portion of the world's carbon emissions. As cities grow and the demand for buildings increases, the search for materials that are both strong and gentle on the environment has become urgent. One family of materials is gaining attention for its potential to replace the heavy, carbon-intensive concrete and steel that dominate modern skylines: engineered wood products. These are not simply planks of timber sawn from a tree; they are manufactured structural materials created by bonding layers of wood together with adhesives to form beams, panels, and columns that are stronger and more consistent than traditional lumber. While these materials have been used successfully in parts of Europe and North America, their adoption in developing economies has been slow, often hindered by questions about cost, durability in hot and humid climates, and a lack of local expertise.

In Nigeria, where rapid urbanization is reshaping the landscape, a team of researchers set out to understand why these sustainable materials are not yet widely used and what would be required to change that. They focused on the construction professionals in Enugu State, a hub of activity in the country's southeast, to map out the specific barriers and drivers that influence the decision to use engineered wood. By combining two established ways of thinking about how new technologies are accepted—looking at the technology itself, the organizations using it, and the environment in which they operate—with a framework for measuring sustainability, the researchers built a clear picture of the path forward. Their work reveals that while the environmental benefits are well understood, the path to widespread use depends heavily on technical confidence, leadership within construction firms, and supportive government policies.

The study began by surveying over three hundred professionals, including architects, civil engineers, quantity surveyors, and timber manufacturers. The researchers asked these experts to rate various factors that might influence their decision to adopt engineered wood products. They looked at the technical side, such as how strong the wood is, how well it resists fire and rot, and whether it is available and affordable. They also examined organizational factors, such as whether a company has the skilled staff to work with the material, if the management is committed to using it, and if the firm has the money to invest. Finally, they considered environmental factors, including government regulations, building codes, market demand, and the general awareness of sustainability issues. The goal was to see how these different pieces fit together to either encourage or block the use of these materials.

The results provided a clear hierarchy of what matters most to these professionals. The strongest driver for adopting engineered wood products was the technology itself. When construction experts felt confident in the structural performance, durability, and fire resistance of the materials, they were much more likely to use them. This finding suggests that the primary hurdle is not a lack of interest in sustainability, but rather a need for assurance that these materials can perform as well as, or better than, the concrete and steel they currently rely on. While the overall confidence in the technology was positive, the data showed that concerns about fire safety and durability in Nigeria's humid climate remained specific points of hesitation that needed to be addressed with clear evidence and certification.

Organizational readiness came in as the second most important factor. The study found that even if the technology is excellent, a construction firm will not adopt it unless its leadership is on board and its staff are trained. Interestingly, the survey revealed that while many firms had technically skilled employees ready to work with these materials, the commitment from top management was often lower. This gap suggests that the potential for change exists within the workforce, but it is being held back by a lack of strategic prioritization from company leaders. The third factor, the external environment, including government policies and market conditions, also played a significant role, though it was less influential than the technology and the organization itself. This indicates that while supportive regulations are helpful, the immediate decision to use engineered wood is driven more by internal confidence and capability than by external pressure.

Once the researchers confirmed that these factors lead to adoption, they measured what happens after the decision is made. They found that using engineered wood products significantly improves sustainability across three key areas: the environment, the economy, and society. The most powerful impact was on environmental sustainability. The professionals surveyed strongly agreed that switching to these wood-based materials leads to a reduction in carbon emissions, better use of resources, and less waste. This aligns with global evidence that wood buildings store carbon and require less energy to produce than concrete or steel. The study also found positive effects on social sustainability, with experts believing that these materials improve the comfort of building occupants and create local jobs through the development of a domestic timber industry.

The economic benefits were also present but were perceived as less certain than the environmental ones. While the professionals saw potential for cost savings and increased productivity, the economic case was viewed as more complex and dependent on local conditions. This reflects the reality that in a developing market, the cost of importing these materials or setting up local manufacturing can be a barrier. The researchers noted that the economic advantage is not yet as clear-cut as the environmental one, suggesting that while the materials are a good investment for the planet and the community, the financial return requires further development of local supply chains and manufacturing capacity.

Based on these findings, the researchers proposed a practical framework to help accelerate the adoption of engineered wood products in Nigeria. They suggest that the most effective approach is to focus first on building technical confidence. This means providing specialized training for architects and engineers on how to design with wood, particularly regarding fire safety and durability in tropical climates. It also involves updating national building codes to explicitly include specifications for engineered wood, giving professionals the legal and technical reassurance they need. Furthermore, the study calls for a stronger push from industry leaders to make sustainability a strategic priority, ensuring that management supports the transition to these new materials.

The framework also highlights the importance of developing a local supply chain. By supporting local manufacturing of engineered wood products, Nigeria can reduce its reliance on imports, lower costs, and create jobs. This would address the economic concerns identified in the study and make the materials more accessible. Finally, the researchers emphasize the need for visible demonstration projects. Seeing these materials successfully used in real buildings within the local context would help overcome skepticism and prove that they work in the Nigerian environment.

This study offers a roadmap for transforming the construction industry in Nigeria and similar regions. It moves beyond the general idea that "wood is good" to show exactly what needs to happen for that potential to be realized. The path forward is not a single leap but a series of coordinated steps: proving the technology works in local conditions, ensuring companies are ready to use it, and creating a supportive policy environment. By addressing these specific areas, the construction sector can move toward a more sustainable future, using materials that are not only strong enough to build the cities of tomorrow but are also kind to the planet that supports them.
