Abstract

Pandemic-driven confinement has intensified Indoor Air Quality (IAQ) concerns in a tropical low-cost housing, where restricted ventilation creates hazardous environments. This research develops a solar-powered green wall prototype integrated with a closed-loop IoT control system to restore environmental fitrah (natural balance) and foster Sakinah (tranquility). By utilizing real-time sensor feedback (PM2.5, CO2, TVOCs) to trigger automated ventilation and irrigation, the system technically bridges spiritual well-being with mechanical stability, defining Sakinah as the psychological outcome of a sustained, sensor-regulated biological equilibrium. Prototype testing achieved an empirical 30.2% reduction in energy consumption (37.38kWh/month) compared to non-regulated models, with operational costs under MYR20. These outcomes prove that active bio-filtration is technically superior to passive greenery in high-humidity climates. The findings offer a scalable framework for retrofitting Malaysian PPR flats and provide a blueprint for integrating active bio-filtration standards into the Uniform Building By-Laws (UBBL), ensuring health equity and environmental resilience in high-density urban zones.
