Literarily Capturing Key Factors Influencing the Long-Term Sustainability of Green Wall Maintenance in Malaysia

Green building and sustainability are current social concerns. The global construction industry is actively promoting the implementation of sustainable green development, with Malaysia being one of the countries that places significant emphasis on these initiatives. Green walls are a crucial building component that closely aligns with sustainability and energy efficiency. Buildings in Malaysia have begun to adopt this well-known. However, despite Malaysia's adoption of this technology in buildings, the Malaysian construction industry still considers it a novelty. Therefore, this study aims to capture the key factors influencing the long-term sustainability of green wall maintenance in Malaysia. A qualitative literacy search was used to collect the needed data and was grounded in a systematic literature review (SLR) approach. The PRISMA process is followed, and the outcome is produced. The findings highlight the key factors influencing the long-term sustainability of green wall maintenance in Malaysia, including plant selection, irrigation and water management, structural and system integrity, environmental factors, cost and budget management, and human factors and expertise. The outcome of the research can help propose a comprehensive maintenance strategy for green walls in Malaysia and lead to a reduction in operation and maintenance costs.
