Abstract

Main climatic thermal problems in urban park in hot humid tropic area are how to minimize high solar radiation and to optimize the wind. Trees have potentials in ameliorating urban park microclimate. Trees configuration is one of determining factors to get benefit of vegetation potential in hot humid urban park.Microclimate simulation of 3 (three) different tree configurations in selected urban park model is carried out with three-dimensional numerical model, ENVI-Met V.3.1 which simulates the microclimatic changes within urban environments in a high spatial and temporal resolution. The simulation results show that an east – west orientation tree line configuration model has a higher temperature reduction compared with the base case model.Keywords: Urban park, hot humid tropic, tree configuration model

Abstract

Urban overheating and limited daylight access are persistent challenges in rapidly densifying tropical cities. This study examines the influence of urban canyon geometry—including building width-to-length ratio, corridor width, and lateral spacing—on surface temperature dynamics and daylight performance. Using Autodesk Forma, 27 building massing configurations were simulated under standardized conditions with a fixed building height of 30 meters and a footprint of 900 m². Surface temperatures were measured at corridor and rear façade points at 10:00 a.m. and 2:00 p.m., while daylight performance was assessed using sun hours and daylight potential indicators. The results indicate that compact building forms with minimal spacing exacerbate heat accumulation and restrict daylight access, whereas configurations with greater spatial permeability enhance both thermal and lighting performance. The optimal configuration featured an elongated building ratio of 1:3, a narrow corridor width of 15 meters, and wide lateral spacing of 30 meters, achieving corridor surface temperatures as low as 33°C and daylight performance values of up to 66%. Beyond its analytical findings, this study highlights the practical applicability of Autodesk Forma as an accessible and user-friendly tool for early-stage massing studies. Compared to more complex simulation platforms such as ENVI-met or CFD, Autodesk Forma enables architects and designers to conduct simple yet effective climate-responsive analyses during the initial phases of building and site design, thereby supporting sustainable urban development in tropical contexts.

Abstract

Urban Heat Island (UHI) poses a growing environmental and public health challenge, particularly in densely populated urban areas with limited green infrastructure. High-density settlements often experience extreme thermal stress due to compact building forms, poor ventilation, and heat-retaining materials, yet lack detailed spatial data to guide mitigation efforts. This study employed UAV-mounted thermal imaging to map and analyze surface temperature distribution across two contrasting residential zones. Results showed that Zone 1, characterized by tightly packed housing and metal roofing, experienced the most severe UHI effect, with 87.64% of its area exceeding 35°C by 15:00. In contrast, Zone 2, with slightly more vegetation and open layout, recorded 83.87% above 35°C at the same time. These findings highlight the significant impact of urban morphology and land cover on thermal performance. This research contributes a high-resolution, drone-based methodology for assessing micro-scale UHI patterns, offering a practical tool for climate-responsive urban planning.
