APPLICABILITY OF GREEN FAÇADES WITHIN HIGH-RISE BUILDINGS IN URBAN BUILT ENVIRONMENTS

Challenges related to urban sustainability can be creatively solved by adding more green infrastructure in the form of vertical vegetation. The constructed environment of urban areas presents a few economic, environmental, and social difficulties. Environmental problems such as noise, water, and air pollution caused by the construction industry is one of the difficulties. Consequently, building green façades is one strategy for addressing climate change issues. This research examines how green façades can be used in high rise buildings in urban settings. The study has the following goals: (i) To determine the potential benefits of green facades for tall buildings in urban built environments and (ii) to investigate major challenges to using green facades in high-rise structures in Malaysia. This research adopts a quantitative research methodology, distributing 116 questionnaires through Google Forms to architectural firms in the state of Selangor. 46 responses were received. Frequency analysis determined that green façades significantly influenced economic factors, specifically in increasing property value. Additionally, they contribute to environmental aspects such as urban environment and sustainability, shading potential, and thermal insulation. Socially, green facades are perceived as a means to provide a better environment for society. However, practitioners in the field have encountered challenges, particularly in the maintenance of buildings and the construction costs associated with implementing green façades in urban built environments. Consequently, recommendations for future research have been proposed considering these findings.
