ОРГАНИЗАЦИЯ АРХИТЕКТУРНОЙ СРЕДЫ ОБЩЕСТВЕННЫХ ПРОСТРАНСТВ В УСЛОВИЯХ СЛОЖНОГО РЕЛЬЕФА

The mountain landscape distinguishes the location of urban routes, the functional-spatial structure and layout of public areas from the design of an urban environment on flat terrain. This study examines the issues of rational use of urban areas in conditions of complex terrain using the example of the territory of the largest city of Chongqing, located in the central part of China. The research is based on an integrated approach, methods of urban planning analysis and functional-spatial modeling. Various aspects of the transformation of complex natural landscapes to expand public urban spaces and form their identity are analyzed using the example of public spaces in the structure of high-density residential development in Chongqing. The study identified the characteristic problems of the planning organization of public areas on difficult terrain (insufficient insolation, lack of green areas, non-standard location of transport infrastructure, irrational organization of pedestrian traffic, lack of public access to public areas, isolation and incoherence of public spaces, etc.). Functional planning models for the organization of public recreational spaces are proposed, which are promising for use both in areas of existing high-density development and for the development of undeveloped territories in the mountainous regions of China. Prospective directions for the development of public spaces in the Baixiangju residential area in Chongqing have been identified.

Perceived Safety Influencing Active Travel to School-A Built Environment Perspective.

Despite the many research studies on active school travel (AST), the number of children walking/cycling to school is decreasing as there is a lack of implementable research evidence. This review through database searches from 2000 to 2020 aims to identify research gaps and explore new perspectives. The articles are selected and screened methodically for systematic presentation of the review. An existing active school travel framework is used to structure and discuss this review paper on mediating factors influencing children's active travel to school, that is the perceived traffic safety, neighborhood safety, and distance to school. Perception of traffic safety could be ameliorated through lateral separation from the traffic, and this could be a new area of research. The neighborhood safety perception may require more research to validate the previous findings. Schools should be located within high-density residential development so that many children can walk to school.

Sustainability Assessment of Mosque: A Case Study of Design Proposal in Bandar Bertam Jaya, Penang

Mosque is a significant building typology for Muslims. Careful consideration on location and capacity should be practiced to increasing accessibility and promote comfort to worshippers. Due to high-density residential development, location of the nearest mosque and sense of unity among Muslims in the area, a local community was proposing a new mosque in Bandar Bertam Jaya, Penang to Majlis Agama Islam Negeri Pulau Pinang. A self-sustained mosque with phased development was proposed by Arkitek ICB Sdn. Bhd. With VELUX Daylighting Simulation and basic ventilation principle, the aim of the research is to study the sustainability of the design comprising daylighting and ventilation aspects respectively and how the proposal can give an impact to energy and resource management. The findings including Average Daylight Factor (ADF), opening sizes, wind speed and direction will also be reflected to Malaysian Standard MS 1525 and MS 2680 to value the sustainability aspect performed by the mosque. The findings of the research can be a reference to the architecture firm and the local community on the performance and sustainability of the proposal.

Generating Residential Layout Based on AI in the View of Wind Environment

There is a contradiction between the high-density residential area development form and comfortable outdoor physical environment. The existing studies on wind environment of high-rise residential areas only provide the guidance for the simple general layouts, which cannot cope with the fact that most high-rise residential areas are mixed of point buildings and board buildings, and it would cost a lot of time and resources to carry out computer simulation of each layout. This paper presents a new tool, which uses the automatic optimization function of genetic algorithm and the prediction function of fully convolutional neural network to integrates three functions: the automatic generation of high-rise residential layout, the simulation of wind environment and the comparison for optimization, to learn plan scheduling and obtain the optimal solution for high-rise residential layout under specific plot ratio and plot conditions, provides guidance for today’s fast-paced architectural design.

Impacts of light rail transit development on neighborhood health: A scoping review through a social determinants of health lens

IntroductionLight rail transit (LRT) has become a popular intervention for addressing the social and economic complexities associated with urban growth. LRT development can exert influence on neighborhood characteristics, such as property values, employment opportunities, and service access. Many of these changes can impact the health of nearby residents by influencing their exposure to the social determinants of health (SDOH). This study maps the literature on LRT development through an SDOH lens and comments on gaps and implications for neighborhood health and transit planning. MethodsThe Arksey and O'Malley scoping review methodology was used to examine existing literature on neighborhood-level impacts of LRT development related to the SDOH. Peer-reviewed articles were included if they focused on an LRT project in an urban center in Canada or the United States, reported on a neighborhood-level impact related to the SDOH, and were published in English between 2004 and 2019. Standardized information was extracted from each included article and thematic analysis was applied to generate impact themes. ResultsA search of three databases yielded 767 non-duplicate records and 29 studies were included in the review. Six impact themes were identified: property values, neighborhood demography, economy, development, transit, and neighborhood perceptions. LRT development was associated with residential property value increases, high-density residential development, new business openings, and increases in neighborhood household income. Articles had limited recognition of the role of LRT development in creating health disparities. ConclusionsThis review demonstrates that transit development can influence the living conditions and resource availability of surrounding areas. Since many of the impacts identified in this study can further social stratification or have differential effects by socioeconomic status, LRT development can be conceptualized as a driver of health inequities. In order to design more effective and equitable transit policy, future research should position transit development as an SDOH.

ІСТОРИЧНІ ПЕРЕДУМОВИ ФОРМУВАННЯ ВИСОКОЩІЛЬНОЇ МАЛОПОВЕРХОВОЇ ЖИТЛОВОЇ ЗАБУДОВИ

The article discusses key issues related to the historical prerequisites for the formation of a high-density low-rise residential development. This is a complex and long process, the stages of which took place at different times and in different countries of the world. Today, such a building is very promising for modern rapidly growing cities, so it is important to track the history of its formation and the features of such planning decisions at different times. Such architecture can become a new vector in the development of modern cities, because low-rise residential buildings are much more comfortable than high-rise buildings. The article gives examples of low-rise city houses in different histories and in different countries. The aim of this work is to review the historical background of the formation of modern high-density low-rise buildings. The following historical examples of low-rise high-density buildings are considered: early single-family residential buildings of the ancient settlements of Mesopotamia and Egypt, residential buildings in Ancient Greece and Rome, blocked residential buildings for workers in the 19th century. In the UK, townhouses of the 1920s and 30s. In the USA, etc. The article shows the planning decisions and the appearance of low-rise high-density residential buildings. The main features of such houses are quarterly development, large-scale man, blocked development and the presence of a small house area.

Assessing the efficiency of indoor and outdoor access-related infrastructure

How does urban density affect the efficiency of access infrastructure? A novel approach considers both ‘outdoor’ and ‘indoor’ access infrastructure. A hypothesis is developed and tested to determine if spatial costs shift from ‘outdoors’ to ‘indoors’ in rising building densities. Taking into account the significance of theoretical research and its impact on decision-making practices on development, a case study in a Chinese city is conducted to assess the spatial costs of building-internal and building-external access for different types of residential neighbourhoods, thereby exploring the relationship between the number of floors and accessibility costs in terms of area consumption. Three different types of residential neighbourhood representing diverse density situations are analysed and evaluated. Although based on a single case study, the results provide valid arguments to substantiate the shift hypothesis. The findings challenge the existing planning notions regarding gains in infrastructural efficiency and instead show reduced efficiencies can occur in high-density development when indoor access is taken into account. Under comparable factors of access quality, compact settlements may even display lower efficiencies than less compact areas. These considerations indicate the need for a more critical and wider view of the efficiency gains provided by dense settlement forms. Policy relevance When building densities increase, the burden of spatial costs for access infrastructure (mobility, traffic access, vertical circulation and parking) shifts from ‘outdoors’ to ‘indoors’, potentially increasing in overall terms. This challenges current ideas in urban planning that higher density leads to gains in infrastructural efficiency. Economic and resource efficiency are clearly reduced when indoor access is taken into account. Indeed, under comparable factors of access quality, compact settlements may have lower efficiencies than less compact areas. These new insights indicate the need for a more critical and wider reappraisal of the efficiency gains provided by dense settlement forms, particularly high-density and high-rise residential development. Developers, planners and designers will need to develop new processes and guidance for evaluating efficiencies of urban settlement and their sustainability.

Biologically active area in low-rise high-denisty housing development with an example of Bialystok

The biologically active area is one of the most important elements of residential development. Its size is determined by the percentage factor established in local spatial development plans and laws regulations. The publication was set minimum values ​​for this ratio for single-family and multi-family housing, and the outcomes were compared with a new type of housing, currently popular in Poland, low-rise high-density residential development. The studies were done on the example of the city of Bialystok, where there are many buildings of this new type of housing.

서울, 자카르타, 마닐라, 방콕 대도시권의 도시확산 비교 분석

This study starts from the issue that the urbanization in developing countries has accelerated urban sprawl through Western-style low-density residential development represented by single-family detached housing. It therefore aims to empirically verify that Korean-style high-density residential development characterized by multi-family housing (‘apartment’), by contrast, has contributed to compact urban development, restricting urban sprawl. International comparison among Seoul, Jakarta, Manila, and Bangkok metropolitan regions shows that the Seoul metropolitan region has the highest proportion of the population living in the central region, compared with the peripheral region. By estimating population density functions, it further demonstrates that the Seoul metropolitan region has the largest gradient, which means the steepest decrease in population density as the distance from the metropolitan center increases. These results confirm that the Seoul metropolitan region is characterized by the most compact urban development owing to the high-density housing development, while the metropolitan regions in the Southeast Asia, particularly Manila and Bangkok metropolitan regions, suffer from the sprawled urban development pattern coupled with the low-density housing development.

Exploring Outdoor Solar Potential in High-Density Living: Analyzing Direct Sunlight Duration for Urban Agriculture in Seoul’s Residential Complexes

Urban agriculture has become a favored activity in many cities around the world. This study explores how urban agriculture’s potential can be maximized in Seoul, South Korea, a city characterized by high-density residential complexes. It selects six existing residential complexes with representative site typologies and diverse density levels. The study’s aim is to assess the impact of various typology and density settings on percentages of ground-level surface with direct sunlight above certain thresholds during warmer seasons when crops can grow. DIVA-for-Rhino is used for simulation. The findings suggest that parallel typologies and lower density levels offer the best performance, while other combinations show mixed results. This study could benefit citizens and policymakers to facilitate urban agriculture practices around the world by suggesting feasible solutions for high-density residential developments.

Reassessing NIMBY: The demographics, politics, and geography of opposition to high-density residential infill

ABSTRACTPlanners often attempt to accommodate growth in already developed areas. Opposition to high-density (i.e., at a higher unit density than surrounding development) residential infill in developed areas is, however, a long-established force in land use politics. We hypothesize that opposition to this development, as well as 6 specific concerns with this development’s impacts, are likely associated with a variety of ideological, demographic, geographical, and political characteristics and that these associations can tell planners much about the character of this opposition. We use a web survey of verified voters in local elections (n = 772) in medium- to medium-high-density ZIP codes to find relationships between these characteristics and respondents’ feelings toward a hypothetical high-density residential infill development. Our findings expose the varied character of responses to this development: respondents of some characteristics—for example, those who strongly value their communities’ attractiveness, vitality, walkability, and bikability—are more likely to have specific concerns while remaining open to the development, indicating the possibility of constructive conversations with these groups. On the other hand, the concerns of other groups, notably those of conservatives, may result from unfamiliarity or even prejudice.

An empirical analysis of Hong Kong's planning control decisions for residential development

Hong Kong's planning control system, despite its critical importance in the land development process, has usually been overlooked in housing policy debates. In particular, the system's innate flexibilities give rise to questions as to whether the Town Planning Board's (TPB) planning control decisions are under the influence of 1) interests of large property developers; 2) government housing policy objectives; and 3) market conditions. In this light, this paper examines the TPB's decisions on applications for housing development in three residential statutory zones since January 1990: R(A) zone (i.e. a zone designated primarily for high-density residential development), R(B) zone (i.e. a zone established primarily for medium-density residential development), and R(C) zone (i.e. a zone intended primarily for low-density residential development). A total of 390 cases are studied. The findings show that the TPB's planning control decisions are subject to market conditions for R(A) zone, and skewed towards the interests of large property developers for R(C) zone. Yet, the decisions for all three zones are not in line with the government's housing policy objectives. Besides, the TPB, while being more receptive towards more intensified residential developments in R(B) zone, is usually against them in R(C) zone. Also found for R(C) zone is that, the TPB is more likely to approve development in urban areas and in new towns, and that it has taken a more pro-development stance since Hong Kong's handover to China. Interestingly, in this zone, while requests for higher site coverage are treated more favourably, the same cannot be said about requests for higher allowable plot ratio or the relaxation of building heights. Policy implications are then discussed.

Leveraging VGI Integrated with 3D Spatial Technology to Support Urban Intensification in Melbourne, Australia

High density residential development in metropolitan Melbourne, where contradictory imperatives of neighbourhood character and urban intensification play important roles, remains an uncertain practice. One key issue for plan implementation is the lack of consistency between authorities, developers and the community in interpreting the standards, design guidelines, and state/local strategies, especially those relating to neighbourhood character. There is currently no mechanism to incorporate community perceptions and place experiences as subjective aspects of neighbourhood character in development assessments. There is also little use of micro-scale and multi-dimensional spatial analysis to integrate these subjective aspects with objective measures (e.g. building volume and height; streetscape) to communicate effectively—and in a limited timeframe—with all stakeholders. This paper explores the potential of two emerging geospatial technologies that can be leveraged to respond to these problems. Evidence in the literature suggests that volunteered geographic information (VGI) can provide community input around subjective aspects of the urban environment. In addition, a deluge of three-dimensional (3D) spatial information (e.g. 3D city models) is increasingly available for micro-level (building- or property-level) assessment of the physical aspects of the urban environment. This paper formulates and discusses a conceptual framework to link these two spatial technological advancements in a virtual geographic environment (VGE) that accounts for micro-scale 3D spatial analysis incorporating both subjective and objective aspects of neighbourhood character relevant in implementing compact city strategies.

Influencing urban development through government demonstration projects

Government-backed high-density infill residential developments are used as a planning policy tool for engaging the building industry and promoting sustainable urban development. There is limited research into the influence such buildings have on the building industry and urban development outcomes. This paper presents analysis from interviews with 14 leading building-industry stakeholders about a demonstration mixed-use building developed by the Victorian state government in Melbourne, Australia. The development included innovative elements addressing environmental sustainability, governance, mixed tenure, mixed use and modular construction. The analysis found that stakeholders were acutely aware of the development, with some innovative elements – such as the modular construction – being monitored by stakeholders informally; other elements – such as environmental sustainability – were of nominal interest. Translation of informal learnings to stakeholder's own companies was lagging. While it is evident that the development has played a role in influencing the building industry to some extent, more effort is required to communicate practical outcomes and learnings in a formal way if sustainable urban development is to be facilitated through the demonstration development planning approach.

The challenge of developing higher density, affordable housing in the inner city of Cape Town

Purpose– The purpose of this paper is to provide an overview of the economics of providing well-located housing in the inner city of Cape Town. The paper emphasises the need to maintain an appropriate balance between the viability and affordability of the product offered to the market and overcoming the value versus cost challenges. While developers have limited influence over value, they do have influence over cost structures through the development approach that is chosen. Moreover, local authorities influence the viability of projects through standards and regulations. The conclusion drawn from the research has considerable implications for the formulation of market-driven housing policy interventions.Design/methodology/approach– In addition to the review of urban economics theory and the literature on the drivers and costs of inner-city, higher-density residential development, a series of interviews with inner-city residential developers was conducted to access current property development cost data and to identify the parameters that determine the viability of inner-city, high-density residential development.Findings– Cape Town, like other South African cities, suffers from being inefficient and inequitable largely due to its low density and sprawling nature. As a result, most planning- and housing-related policy interventions advocate the provision the higher-density, more affordable residential housing in well-located areas such as the inner city. However, to date, these policies have, on the whole, been unsuccessful in achieving these outcomes. This paper argues that this is because these policies largely do not take urban economics into account and fail to address the value versus cost tension that needs to be overcome to allow for the provision of such accommodation. Based on the viability calculations provided, the research illustrates the main cost drivers associated with higher-density, inner-city residential development and makes certain recommendations as to how these cost barriers can be reduced.Research limitations/implications– Financing arrangements and taxation implications have not been accounted for as these are often specific to the developer and thus cannot be generalised.Practical implications– The solutions put forward by the paper offer lower-income households the ability to successfully compete with higher-income households and other land uses for well-located space in Cape Town’s inner city.Social implications– The findings of this research illustrate the type of interventions that the public and private sectors can consider to improve the viability and affordability of affordable housing units in city centres located in emerging countries.Originality/value– While traditional urban economic concepts are drawn upon, the paper contributes to addressing the challenge of providing higher-density, more affordable accommodation in South African inner cities. It does this by applying these well-known concepts to the inner city of Cape Town and draws on current data and developer views to accurately diagnose the problem and, in turn, to offer pragmatic solutions.

What gives to keep that price point? High-density residential developments

High-density living is now widely accepted in the built environment. At the apartment entry price-point, space and place appear to be the key considerations, with limited attention to a building’s social, physical and environmental features. To examine this, the researchers interviewed leading Melbourne property developers and consultants to identify the challenges of incorporating innovation relative to governance, design, and construction and building operations into the competitive high-density property development market. Responses demonstrate that post-occupancy analysis can be a tool to better inform property stakeholders. When presented to prospective purchasers, this information could shift the key consideration from an entry price point to the features of a well-designed apartment and so redirect the current ‘minimalist’ approach adopted by some new property development entrants to improving occupier living experience and ongoing maintenance costs.

Household Waste Management in High-Rise Residential Building in Dhaka, Bangladesh: Users? Perspective

The Dhaka City Corporation (DCC) is primarily responsible for collecting and managing waste in Dhaka, Bangladesh. A significant amount of waste in Dhaka is not collected due to lack of infrastructure, funds and collection vehicles. Despites Dhaka’s limited waste management service, community based door-to-door waste collection from households to local waste bins is considered as a success. Informal waste recycling systems is also highly effective in waste recycling and job creations for the poor. Even though both horizontal and vertical expansion is prevalent in Dhaka, there has been an increasing trend in vertical expansion of the city in recent years as horizontal expansion is not possible due to barriers such as the built up urban core and low lying flood plains. Very limited number of studies has been conducted on waste management system in high-rise residential buildings in Dhaka. Therefore, this study focuses on the waste management scenario of high-rise residential buildings in Dhaka. The study is particularly interested in the socio-demographic, cultural and environmental features in high-rise residential buildings. The study identified key areas in waste management systems in high-rise residential buildings which is the avenue for future studies for integrating waste management strategies in high density residential development in Dhaka. Based on the findings, the study recommends a further examination of the integration of waste management infrastructure in the high-rise residential building development in Dhaka.

The Moderating Influence of Property Legislation on Planning Policy and Urban Form

This paper investigates the role that property titling legislation has had on the form of high-density residential development. A conceptual framework is developed for theorising the role of property legislation in moderating the impact of urban land use policy. It is argued that the impact of legislation on urban form is much more significant and direct than is often implied or suggested in reviews of planning policy. It is argued that property legislation has a greater role than simply supporting the implementation of urban planning policy. Property legislation has a moderating influence on policy and provides a barrier to the implementation of urban policy. To support this argument, the paper considers the development and implications of Western Australia’s strata titling legislation for the form of high-density development in that state’s capital city.

Simulating the impacts of future land use and climate changes on surface water quality in the Des Plaines River watershed, Chicago Metropolitan Statistical Area, Illinois

Modeling the effects of past and current land use composition and climatic patterns on surface water quality provides valuable information for environmental and land planning. This study predicts the future impacts of urban land use and climate changes on surface water quality within Des Plaines River watershed, Illinois, between 2010 and 2030. Land Change Modeler (LCM) was used to characterize three future land use/planning scenarios. Each scenario encourages low density residential growth, normal urban growth, and commercial growth, respectively. Future climate patterns examined include the Intergovernmental Panel on Climate Change (IPCC) Special Report on Emission Scenario (SRES) B1 and A1B groups. The Soil and Water Assessment Tool (SWAT) was employed to estimate total suspended solids and phosphorus concentration generated at a 10 year interval. The predicted results indicate that for a large portion of the watershed, the concentration of total suspended solids (TSS) would be higher under B1 and A1B climate scenarios during late winter and early spring compared to the same period in 2010; while the summer period largely demonstrates a reverse trend. Model results further suggest that by 2020, phosphorus concentration would be higher during the summer under B1 climate scenario compared to 2010, and is expected to wane by 2030. The projected phosphorus concentrations during the late winter and early spring periods vary across climate and land use scenarios. The analysis also denotes that middle and high density residential development can reduce excess TSS concentration, while the establishment of dense commercial and industrial development might help ameliorate high phosphorus levels. The combined land use and climate change analysis revealed land use development schemes that can be adopted to mitigate potential future water quality impairment. This research provides important insights into possible adverse consequences on surface water quality and resources under certain climate change and land use scenarios.
