Abstract

Coastal urban areas, one of which is the PIK 2, Tangerang Regency, Indonesia, as the study case, have distinctive climate characteristics: changes in land and sea breezes during different seasons and high humidity and wind speed levels, which affect thermal comfort. The optimal building mass needs to be studied to achieve ideal thermal comfort conditions, which can effectively respond to climate characteristics different from those of other urban areas. This paper investigates the existing urban thermal environment and models the impact of building orientation, form, and H/W ratio simulated in ENVI-met. Based on the study findings, it has been determined that positioning a building diagonally towards the sea at a 45-degree angle effectively reduces excessive wind speeds, resulting in a favorable PMV score. Additionally, incorporating a sky bridge into the building form design provides adequate shading and contributes to achieving optimal thermal comfort in coastal-climate urban areas. Moreover, the optimal H/W ratio is 0.5, which can reduce wind speed without significantly lowering the temperature, thereby maintaining thermal comfort.

Abstract

Climate change poses a challenge for many urban areas worldwide. Inner cities face significant climate change impacts; one such inner city is the Andir Area in Bandung. Andir Area faces climate change issues due to its limited green space coverage of 18.15%, which impacts flood risks and high carbon emissions. However, the Andir Area also has the potential for heterogeneity and societal tolerance. With its potential and challenges, Andir Area can be developed as a climate village prototype, prompting the need for research exploring design strategies to mitigate climate change based on harnessing community heterogeneity. Collaborative planning, such as design charrettes, is one approach that leverages the heterogeneity of a community. This research method is a collaborative experimental study and utilizes design charrettes as an alternative approach to designing a heterogeneous and climate-resilient area. The research findings indicate that the quality of the Andir Area can be enhanced by integrating climate change mitigation with community heterogeneity through participatory design charrettes. The benefit of this research lies in providing insights to reduce the impact of climate change in the Andir Area through community participation. Overall, this article offers valuable perspectives on designing areas that can adapt to the challenges of climate change while preserving social-cultural heterogeneity, acculturation, and tolerance.
