SIMULATION MODEL OF GREEN OPEN SPACE ON MICROCLIMATE PERFORMANCE IN TROPICAL COASTAL AREA

This research aimed to simulate scenario of green open space to mitigate heating within microclimate performance. It also optimized the composition of the built environment's surface to reduce urban heating. A numerical model was simulated using ENVI-met, and spatial analysis was conducted with ArcGIS software. Three different scenarios were established to propose solutions for heating reduction. Simulation showed that a balanced composition between buildings and vegetation resulted in air temperature decrease of 2.45°C to 3.31°C compared to no-greenery simulation. Meanwhile, when compared to the existing situation, hybrid greenery achieved a 3.50°C air temperature decrease. This research offered valuable insights into the urban environment by prioritizing landscape design, focusing on buildings and the composition of green open space in surrounding areas
