Description
Rapid urbanization in Bengaluru has aggravated the Urban Heat Island (UHI) effect and decreased green space in high-rise developments. This phenomenon creates elevated "heat hotspots"that increase cooling energy demand and impact public health, social equity, and economic sustainability. To mitigate these issues, balcony greening and other Vertical Greening Systems (VGS) are considered nature-based solutions. This research paper integrates a comprehensive literature review of VGS performance with a pilot study examining Bengaluru residents' perceptions. The pilot study comprises a cross-sectional survey of 55 participants (95% CI: 13.2%). Existing literature demonstrates VGS effectiveness in reducing surface temperature by 2-4C and ambient temperature by 1-3C, thereby reducing cooling energy requirements by 15-23%. Survey results indicate high acceptance (80.9%, 95% CI: 68.5-89.7%), with 87.5% (95% CI: 76.0-94.1%) recognizing VGS benefits for cooling and psychological stress reduction. However, maintenance burden (54.5%), structural concerns (25.5%), and native flora scarcity (73.2%) were identified as significant barriers. Chi-square analysis revealed statistically significant associations between acceptance levels and perceived benefits (?2 = 18.42, p < 0.001), indicating strong adoption potential when barriers are addressed. This research paper offers critical insights into tropical high-rise vertical greening perceptions, informing climate-resilient urban development policies for Bengaluru and similar megacities.
