Barriers to Undertaking Green Building Projects in Developing Countries: A Turkish Perspective
Introduction
Green Building Projects in Developing Countries face a unique set of challenges that differ significantly from those in developed economies. While the global construction industry is increasingly pivoting toward sustainability to combat climate change, nations with emerging economies often struggle to implement these green practices at scale.
A recent study by Emre Caner Akcay, published in Buildings (2023), provides a granular analysis of these obstacles through the lens of Turkey, a nation that serves as a critical case study for other developing regions.
This article synthesizes the key findings, methodology, and policy recommendations from this research, offering vital insights for housing professionals, policymakers, and researchers interested in the future of sustainable construction.
The Global Context and Turkish Landscape
The construction sector is a primary contributor to global environmental degradation, accounting for approximately 35% of total energy consumption and 38% of CO2 emissions worldwide.
In response, Green Buildings (GBs) have been identified as an essential strategy for achieving sustainable development goals. GBs are defined as structures that minimize negative environmental impacts through resource-efficient construction processes, offering benefits such as reduced energy use, lower waste output, and improved indoor air quality.
Turkey, classified as a developing country with the world's 23rd largest economy, places significant importance on GBs. The construction sector contributes nearly 9% to Turkey's Gross Domestic Product (GDP) and roughly 30% when indirect effects are included.
Despite having 518 certified green buildings—ranking sixth globally—Turkey remains far from its government sustainability targets. Understanding the specific impediments to Green Building Projects in Developing Countries is, therefore, not just an academic exercise but a practical necessity for economic and environmental progress.
Methodology: Quantifying the Obstacles
To accurately identify the hurdles facing the industry, the study employed a robust quantitative approach. The research began with an extensive literature review that identified 17 potential barriers to undertaking GB projects. These barriers ranged from financial constraints to regulatory gaps.
A questionnaire survey was administered to 116 construction practitioners in Turkey, including civil engineers, architects, and mechanical/electrical engineers working in both public agencies and private companies. The respondents rated the severity of each barrier on a five-point Likert scale.
The data was analyzed using descriptive statistics to rank the barriers and inferential statistics, specifically exploratory factor analysis, to group them into broader categories. This methodological rigor ensures that the findings regarding Green Building Projects in Developing Countries are statistically valid and representative of professional consensus.
Key Barriers to Green Building Projects in Developing Countries
The study revealed that ten out of the 17 identified barriers were significantly critical, with a mean score above the threshold of 3.50. The results highlight that the challenges are multifaceted, involving economic, educational, and structural issues.
Higher Construction Cost
The most critical barrier identified was the higher construction cost. Respondents indicated that the initial investment for GBs is perceived as significantly higher than for conventional buildings. In Turkey, this issue is exacerbated by the fact that many green materials and technologies are imported.
Consequently, project costs are highly sensitive to fluctuations in the Turkish currency exchange rate, leading to frequent cost overruns and making developers hesitant to commit to Green Building Projects in Developing Countries.
Lack of Knowledge and Expertise
The second most significant barrier was a lack of knowledge about GBs. The green building industry in Turkey is relatively young, with only about a decade of history. Many stakeholders, including designers and contractors, lack the specialized expertise required to implement green technologies effectively.
This knowledge gap creates a cycle of reluctance, as professionals are unwilling to adopt methods, they do not fully understand. This finding is consistent with broader trends observed in Green Building Projects in Developing Countries, where educational infrastructure often lags behind technological advancements.
Regulatory and Rating System Gaps
The lack of an authorized, locally adapted GB rating system ranked third. While international systems like LEED (Leadership in Energy and Environmental Design) are used, they present challenges.
For instance, LEED requirements are in English, creating language barriers for local teams, and the criteria may not always align with local climatic or economic conditions.
The absence of a standardized, government-backed rating system creates uncertainty for investors and practitioners alike.
Supply Chain and Market Demand Issues
Unavailability of GB materials and inadequate market demand were also top-tier barriers. The scarcity of local suppliers for green materials forces reliance on imports, further driving up costs and lead times.
Additionally, there is insufficient demand from building owners and users, largely due to a lack of awareness regarding the long-term benefits of GBs. Without a strong market pull, developers have little incentive to overcome the higher upfront costs associated with Green Building Projects in Developing Countries.
Categorized Analysis of Barriers
Through factor analysis, the study grouped the 17 barriers into five distinct factors. This categorization helps policymakers target interventions more effectively.
Cost- and Demand-Related Barriers
This factor explained the largest portion of variance (22.73%). It includes higher construction, design, and operation costs, alongside inadequate market demand. The high perceived cost is the primary deterrent, despite evidence that long-term operational savings can offset initial investments.
The lack of demand is closely tied to this, as potential users are often unaware of the economic benefits, such as reduced maintenance costs and higher property values.
Market-Related Barriers
Accounting for 15.49% of the variance, this factor includes the lack of training for professionals, scarcity of completed GB projects, unavailability of GB materials, and inadequate green material suppliers.
The "chicken-and-egg" problem is evident here: without completed projects, there are no examples to inspire demand; without demand, there is no incentive to train professionals or develop local supply chains. This structural deficit is a common theme in Green Building Projects in Developing Countries.
People-Related Barriers
This factor (13.95% variance) encompasses the lack of knowledge about GBs, the lack of expert professionals, and inadequate environmental awareness. It highlights the human capital deficit.
The study suggests that technology transfer and educational initiatives are crucial to overcoming these barriers. Integrating universities, industries, and governments could help build a knowledge-based society capable of supporting sustainable construction.
Government-Related Barriers
Explaining 12.56% of the variance, this factor includes the lack of government incentives, the lack of regulations, and the absence of an authorized rating system. The study emphasizes that voluntary adoption is insufficient.
Mandatory regulations and financial incentives, such as tax exemptions or subsidies for using domestic green materials, are necessary to drive change. The success of similar incentives in Turkey's renewable energy sector serves as a model for what could be achieved in the building sector.
Time-Related Barriers
The least critical factor (10.18% variance) included longer construction and design times. While GBs do require more time for planning and execution, respondents viewed this as a manageable issue compared to cost and knowledge gaps.
This suggests that if financial and educational barriers are addressed, time constraints can be mitigated through better project management.
Strategic Recommendations for Policymakers
Based on the findings, the study offers several strategic recommendations for promoting Green Building Projects in Developing Countries:
- Financial Incentives: Governments should introduce tangible financial incentives, such as tax breaks, low-interest loans, or density bonuses, to offset the higher initial costs of GBs.
- Local Production: Policies should encourage the local manufacturing of green building materials. This would reduce dependency on imports, stabilize costs, and create jobs.
- Education and Training: Comprehensive training programs for architects, engineers, and contractors are essential. Universities should integrate GB principles into their curricula, and professional bodies should offer certification courses.
- Authorized Rating System: Developing a national GB rating system that reflects local conditions and is available in the local language would streamline the certification process and increase adoption.
- Awareness Campaigns: Public awareness campaigns should highlight the long-term economic and health benefits of GBs to stimulate market demand. Demonstrating successful case studies can help convince skeptical developers and homeowners.
Conclusion
The transition to sustainable construction is imperative for mitigating climate change, yet Green Building Projects in Developing Countries face distinct hurdles that require tailored solutions.
The Turkish perspective offered by Akcay's study reveals that while cost is the most immediate barrier, it is deeply intertwined with issues of knowledge, supply chain maturity, and regulatory framework.
By addressing these barriers through a combination of financial incentives, educational initiatives, and localized policy reforms, developing nations can accelerate the adoption of green building practices.
The findings from Turkey are not isolated; they resonate with experiences in other emerging economies, suggesting that the strategies proposed here have broad applicability.
For researchers and housing professionals, this study provides a clear roadmap for understanding and overcoming the complexities of Green Building Projects in Developing Countries, ultimately contributing to a more sustainable and resilient built environment.
