Mixed-Use Developments And Urban Megaprojects In The Global South : A Systematic Review And Interpretation Of A Blurred Intersection, Federico Puggioni, Nij Tontisirin

NAKHARA (Journal of Environmental Design and Planning)

This article examines the intersection of two distinct strains of urban studies: mixed-use development and urban megaprojects, through a systematic review of literature. One strain focuses on integrating diverse uses and functions within a single space, known as 'mixed-use'. The other originates from the technical complexities of megaprojects adapted to architecture and urban design. The article seeks to address a gap in the literature by clarifying the conceptual yet geographical overlaps between these two strains, which often have broad, blurred boundaries; it proposes a novel framework for defining and interpreting the related literature at this conceptual intersection.

A First Model Foundation Design Of Wood Pillar In Banjarmasin Swampland, Nursyarif Agusniansyah, Gusti Novi Sarbini, Akbar Rahman, Muhammad Tharziansyah

ASEAN Journal on Science and Technology for Development

Banjarmasin's swampland presents distinct characteristics that make it suitable for constructing homes, but it also requires special attention, especially concerning the foundation. The soil in this area often has extremely low carrying capacity, which poses a significant challenge for construction. Mistakes in choosing construction materials, coupled with mismatched building loads and inadequate foundation functions, often result in foundation failures—a common cause of building collapses. As the complexity and functionality of buildings increase, the need for more thoughtful house design becomes more crucial. The commonly used wooden pile foundation, while popular, has limited load-bearing capacity, necessitating modifications to enhance its strength. …

Influence Of Sociocultural Aspects And Home Modification On Fall Risks Mitigation Among The Elderly In Thailand, Sumavalee Chindapol

NAKHARA (Journal of Environmental Design and Planning)

This study investigates the impact of sociocultural dimensions on home modifications aimed at mitigating fall risks among elderly individuals residing in community settings. Personal measurements and questionnaire interviews were conducted across five regions in Thailand. Additionally, fall risk assessments were performed on the households of the elderly participants. These assessments incorporated both personal health factors and environmental risks associated with falls, resulting in quantifiable scores. The factors included health conditions, body size, sociocultural factors such as family conditions, physical-cultural aspects of elevated houses, bathroom and bedroom. The research revealed that these factors are significantly associated with fall risk (ρ <0.01), except body dimensions. Differences in body size among elderly individuals in different regions were significantly related to incidences of fall risk (ρ <0.05 in Chiang Mai female, Khonkaen male, Rangsit female, and Songkhla female). The contribution of this research is that different regions have varying body limitations and living culture. It was concluded that elderly females in Chiang Mai are at the highest risk of falling due to body shrinkage, residing in vernacular houses with hazards, and living alone. Overall, universal design may not be directly applicable for home modification in each region.  Consequently, the study suggested that home modifications alone may not offer a comprehensive solution for mitigating fall risks as sociocultural factors related to living conditions also play a significant role in shaping these outcomes.

Indonesia Kaya Park, located in Mugassari, Semarang City, is an urban park and public space managed by the Djarum Foundation. Despite numerous studies evaluating its accessibility and biophilic elements, the condition of traffic noise nor potential interventions have been considered. The research question aims to understand the traffic noise condition of Indonesia Kaya Park and identify necessary interventions. The study used a mixed methodology, …

Evaluating And Optimizing Acoustical Reverberation Time And Material Cost For Classrooms Using Building Information Modeling (Bim) And Generative Design (Gd) Tools, Chavanont Khosakitchalert, Taki Eddine Seghier

NAKHARA (Journal of Environmental Design and Planning)

Reverberation time (RT) measures how long sound takes to decay in a space, affecting speech intelligibility and sound quality. Calculating RT using Sabine’s formula is time-consuming and error-prone due to manual extraction of room volume and material surface areas. Balancing RT and cost further complicates material selection. This paper automates RT calculation and optimization using Building Information Modeling (BIM) and generative design (GD). Sound absorption coefficients are input into a BIM model’s material properties, and visual programming (VP) extracts room geometries, materials, and absorption coefficients to compute RT and material costs. A multi-objective optimization algorithm in Autodesk GD identifies the …

The Sociopolitical Manifestation Of Built Environment In Rural Thailand : Holistic Development For An Aging Society?, Sirima Thongsawang, Ampa Kaewkumkong

NAKHARA (Journal of Environmental Design and Planning)

Changes in demographic structures in an aging society have diminished farming employment and incomes of old residents of Talat Mai subdistrict, Angthong Province, Thailand. Under decentralization, the local government assumes primary development responsibility in managing the basic needs of citizens. This case study demonstrates how the local government uses the built environment—Wiset Chai Chan Historical Park Royalty Monument —as an instrument for community development to enhance life quality for old residents. This study examines ways in which the park's construction as a built environment are shaped and consequences due to community development as an aging society. Data was gathered by …

A Framework For Ordinary Urban Heritage Mapmaking : The Case Of Trok In Rattanakosin, Bangkok’S Historic Center, Prin Jhearmaneechotechai

NAKHARA (Journal of Environmental Design and Planning)

This research offers an alternative mapmaking framework for Ordinary Urban Heritage (OUH), specifically applied to the Trok (local alleys) of Bangkok's Rattanakosin district. Departing from conventional approaches that might map Trok solely as pedestrian urban patterns, this framework uniquely explores Trok as dynamic urban spaces that enable the manifestation of diverse everyday heritages, including temporary commercial activities, people’s way of living, and sacred spaces, thereby revealing a richer understanding of OUH. The framework's development is grounded in the analysis of existing mapping practices, historical maps, and non-participatory surveys, incorporating five key OUH selection criteria sensitive to these dynamic manifestations: (1) …

NAKHARA (Journal of Environmental Design and Planning)

Amid rapid urbanization and modernization, traditional Huizhou dwellings face significant challenges in balancing the preservation of architectural authenticity with the practical needs of adaptive reuse. This study investigates the tensions between maintaining cultural and structural integrity and meeting evolving lifestyle and functional demands. Adopting a resident-centered perspective, the research employs a quantitative survey method, collecting 390 valid responses from two UNESCO-listed villages. A structural equation model (SEM) is used to examine the influence of conservation status, government policy, value recognition, and authenticity on residents’ perceptions of adaptive reuse. While findings indicate strong resident support for preserving traditional architectural styles and …

Tradition And Modernity : The Adaptation Of Outdoor Spaces In Traditional Balinese Dwelling, Kristanti Paramita, Aswin Indraprastha, Agus Hariyadi, Yandi Andri Yatmo, Paramita Atmodiwirjo, Rini Suryantini

NAKHARA (Journal of Environmental Design and Planning)

This study investigates the dialectical relation between tradition and current everyday domestic practices in traditional Balinese dwellings that manifest through the spatial adaptation of their outdoor spaces. Traditional Balinese dwellings consist of a compound collection of partly open pavilions surrounded by open spaces, following the symbolic classification of Balinese cosmology, Sanga Mandala. Dwelling adaptation becomes necessary to enable the support of the changing household needs throughout time, aiming to capture a process that emerges in the current traditional dwellings bounded by a particular cultural order. This study focuses on the spatial adaptation strategies of the outdoor spaces as a …
