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

Urbanization and creative lifestyles have driven the emergence of new collaborative spaces in urban areas, including creative spaces built atop traditional markets. This study evaluates the property productivity of The Hallway Space, a youth-culture-based creative space developed on the upper floor of Pasar Kosambi, Bandung, using the Property Productivity Analysis framework (Wilkinson & Reed, 2008), which includes physical, legal, and locational attributes. The research adopts a qualitative-descriptive approach through a case study strategy, utilizing data triangulation from primary sources (semi-structured interviews with the manager and tenants) and secondary sources (Google Maps online reviews analyzed through content analysis, text mining, and open coding). The findings indicate that The Hallway Space successfully creates social and visual added value, enhances place identity, and fosters community interaction, though it still faces challenges related to thermal comfort, navigation, and vertical accessibility. Most visitors perceive the space positively in terms of activities and social atmosphere, despite issues concerning signage and ventilation. This study highlights the importance of evaluating creative spaces not only from social and cultural aspects but also as productive and sustainable commercial properties, particularly in the context of adaptive reuse within traditional market environments.

Abstract

Streetscape plays a crucial role in shaping the visual identity of urban areas and supporting the function of public spaces as hubs for social interaction and creative economic activities. This study examines the physical transformation of streetscape elements in the “Old City” of Banjarmasin across three phases: pre-intervention (2015–2017), post-rejuvenation (2018–2020), and post-revitalization (2021–2023). Using Habraken’s theory of Form, the Physical Order with its levels of intervention—support, infill, and treatments—this research employs qualitative methods, including literature review and visual documentation through Google Maps and Google Street View. The analysis focuses on streetscape components such as roads, building elements, and street furniture. Findings reveal that before intervention, the streetscape appeared basic and lacked regional identity. The rejuvenation phase brought aesthetic improvements through paving blocks, guiding blocks, signage, and the addition of furniture. The revitalization phase introduced more profound changes, including adaptive reuse of old shophouses, murals, creative signage, and rearranged façades, which collectively strengthened the area’s visual identity. These transformations demonstrate a progression from support to infill and treatments, resulting in a dynamic, adaptive environment aligned with the socio-cultural needs of modern communities, particularly Generation Z. The study contributes theoretically to housing and settlement architecture and provides practical insights for sustainable urban rejuvenation and revitalization projects, highlighting the novelty of applying the levels of intervention framework to streetscape transformation.
