The paper examines, within the framework of the standard von Thünen type model with no congestion, the market equilibrium urban form under a regime of commuters who use both the auto and the transit modes, but with no transfers, for their journey to work. There is an extension, however, in that households are assumed to be operating under both an income constraint and a time constraint. The rent and density gradients are obtained in closed forms. Comparative statics are performed, and some policies regarding parking fees, pricing, and investment in the two modes are tested. It is shown that the city may consist of three rings, where the residential location of the user of one mode is split by the residences of the users of the second mode.

The purpose of this paper is to investigate the contribution of urban morphology to the formation of microclimatic conditions prevailing within urban outdoor spaces. We studied the compact form of a city and examined, at a detailed, street plan level, elements related to air temperature, urban ventilation, and the individual’s thermal comfort. All elements examined are directly affected by both the urban form and the availability of open and green spaces. The field study took place in a typical compact urban fabric of an old city center, the city center of Thessaloniki, where we investigated the relationship between urban morphology and microclimate. Urban morphology was gauged by examining the detailed street plan, along with the local building patterns. We used a simulation method based on the ENVI-met© software. The findings of the field study highlight the fact that the street layout, the urban canyon, and the open and green spaces in a compact urban form contribute decisively both to the creation of the microclimatic conditions and to the influence of the bioclimatic parameters.

This short note considers the migration of the skyscraper from New York and Chicago to Asia and its absence in the emerging megacities of the Global South. Following 9/11, many commentators assumed that the skyscraper was finished, but this was clearly not the case, with super-tall construction now accelerating. However, the distributions of contemporary skyscrapers show us that there are shifts in global power and also in urban form.

In casting a new look at city; this study interprets the urban form in respect of the role played by human perception of space. The main aim of this research at a macro level is to attain a strong theorical basis through a multi-dimensional approach to the city. The method of analyzing and carrying out a critique of it at an applied level will clarify the impact, which cultural factors have in the formation of urban form. This preliminary recognition and idealism is based on a hermeneutic and deductive method that is particular to the intellectual sciences In the process of devising theories, studying the urban planning texts related to the subject of study and the conclusion from the field study which is carried out in the Isfahan Naghshe Jahan square in the Safavy period played a key role in the research in addition to the goals and questions.

The study of physical and social divisions in divided societies has long been an area of study, such as the continued usage of 'peace walls' in Belfast, hostile architecture to prevent anti-social behaviour and rough sleeping, and the securitisation of private spaces. In the context of a new drive to create a smart district, this paper looks at the relationship between smart urbanism and planning, and at the spatial and social divisions between a new 'gentrifying' and well-educated community in the Dublin Docklands and established communities in the area. The Dublin Docklands redevelopment marks a significant break from a pattern of suburbanisation and inner-city decline and repurposes part of the former port area as a city centre extension. The paper accounts for the reshaping of the Dublin Docklands as a ‘smart district’ in collaboration with the city authorities, based on over thirty semi-structured interviews and participant-observation at consultation events. It argues that reductive definitions of smart cities as networking technologies be reworked into broader considerations on urban technologies and the future of cities, with greater emphasis on the relationship between technologies branded as ‘smart’ and the material and digital manifestation of boundaries in urban form.

A series of new districts appeared in São Paulo between 1915 and 1940, all inspired in the garden-city concept created by Ebenezer Howard. The City of São Paulo Improvements and Freehold Land Company Limited established some of them in the southwest sector of the city, near downtown: Jardim América (1915), Butantã (1921), Alto da Lapa (1921), Pacaembu (1925), and Alto de Pinheiros (1931). Other developers carried out land subdivisions inspired in the same garden-districts concepts, but in more distant areas. The following garden-districts were built in the southern area of the city: Chácara Flora (1928), Interlagos (1938), and Granja Julieta (1956). Unlike central garden-districts, the history of the outlying garden-districts was seldom or only partly studied. Given this scenario, this study aims to fill a historiographical gap on Interlagos garden-district, which was born as “Interlagos Satellite Spa Town”. Its form is such an important example of landscaping and cultural heritage that the district was listed as protected by the city heritage agency in Resolution nº 18, November 23, 2004, in view of the morphological and historical features of the original land subdivision. This study relies on an urban morphology cognitive study which, according to Rego and Meneguetti (2011), aims to expand the knowledge on the origins and explanations of that urban form. The study presents unpublished data on the district formation, taken mainly from a survey carried out in newspapers from the 1930s and 1940s.

The first half of the 20th century was a turning point in the history of India with provincial rulers making significant development that had positive contribution and lasting influence on India’s growth. They served as architects, influencing not only the socio-cultural and economic growth but also the development of urban built form. Sayajirao Gaekwad III was the Maharaja of Baroda State from 1875 to 1939, and is notably remembered for his reforms. His pursuit for education led to establishment of Maharaja Sayajirao University and the Central Library that are unique examples of Architecture and structural systems. He brought many known architects from around the world to Baroda including Major Charles Mant, Robert Chrisholm and Charles Frederick Stevens. The proposals of the urban planner Patrick Geddes led to vital changes in the urban form of the core city area. New materials and technology introduced by these architects such as use of Belgium glass in the flooring of the central library for introducing natural light were revolutionary for that period. Sayajirao’s vision for water works, legal systems, market enterprises have all been translated into unique architectural heritage of the 20th century which signifies innovations that had a lasting influence on the city’s social, economic, administrative structure as well as built form of the city and its architecture. This paper demonstrates how the reformist ideas and vision of an erstwhile provincial ruler lead to significant architecture at the turn of the century in Princely state of Vadodara.

Since the publication of the book ‘Spacematrix. Space, density and urban form’ (Berghauser Pont and Haupt, 2010), the Spacematrix method has been linked back to its theoretical foundations by Steadman (2013), is further developed using the measure of accessible density to arrive at a density measure that more closely relates to the environment as experienced by people moving through the city (Berghauser Pont and Marcus, 2014) which then is used to arrive at a multi-scalar density typology (Berghauser Pont et al. 2017). This paper will take yet another step in the development of the Spacematrix method by including the measure of network density in the classification which until now was not used to its full potential. Important for successful classification is the ability to ascertain the fundamental characteristics on which the classification is to be based where the work of Berghauser Pont and Haupt (2010) will be followed addressing three key variables: Floor Space Index (FSI), Ground Space Index (GSI) and Network density (N) where especially the last was not fully included in the earlier work. Besides a typology based on these three variables, this paper will also result in a robust statistical method that can later be used on larger samples for city-scale comparisons. Two statistical methods are tested: hierarchical clustering and centroid-based clustering and besides a general discussion about their strong and weak points, the paper shows that the hierarchical method is more convincing in distinguishing differences in both building type and street pattern that is especially captured with Network density (N). As this method is not useful for large datasets we propose a combination of the two clustering methods as the way forward.

Abstract This study discusses the interplays between urban form and energy performance using a case study in Singapore. We investigate educational urban quarters in the tropical climate of Singapore using simulation-based parametric geometric modelling. Three input variables of urban form were examined: street network orientation, street canyon width, and building depth. In total, 280 scenarios were generated using a quasi-Monte Carlo Saltelli sampler and Grasshopper. For each scenario, the City Energy Analyst, an open-source urban building energy simulation program, calculated solar energy penetration. To assess the variables’ importance, we applied Sobol’ sensitivity analysis. Results suggest that the street width and building depth were the most influential parameters.

In the context of the European city, the regeneration of former industrial sites is a unique opportunity to actively steer urban development. These plots of land gain strategic importance in actively triggering development on the city scale. Ideally, these interventions radiate beyond the individual site and contribute to the strengthening of the location as a whole. International competition between locations is rising and prosperous development a precondition for wealth and wellbeing. This approach to the regeneration of inner city plots makes high demands on all those involved. Our framework suggests a stronger focus of the conceptualization and analysis of idiosyncratic resources, to enable innovative approaches in planning. On the one hand, we are discussing spatially restrained urban plots, which have the capacity and need to be reset. On the other hand, each plot is a knot in the web of relations on a multiplicity of scales. The material city is nested into a set of interrelated scale levels – the plot, the quarter, the city, the region, potentially even the polycentric megacity region. The immaterial relations however span a multicity of scale levels. The challenge is to combine these two perspectives for their mutual benefit. The underlying processes are constitutive to urban space diversity, as urban form shapes urban life and vice versa.
