- Typologies have always played an important role in urban planning and design practice and formal studies have been central to the field of urban morphology. These studies have predominantly been of a historical-qualitative nature and do not support quantitative comparisons between urban areas and between different cities, nor offer the precise and comprehensive descriptions needed by those engaged in urban planning and design practice. To describe contemporary urban forms, which are more diffuse and often elude previous historic typologies, systematic quantitative methods can be useful but, until recently, these have played a limited role in typo-morphological studies. This paper contributes to recent developments in this field by integrating multi-variable geometric descriptions with inter-scalar relational descriptions of urban form. It presents typologies for three key elements of urban form (streets, plots and buildings) in five European cities, produced using statistical clustering methods. In a first instance, the resulting typologies contribute to a better understanding of the characteristics of streets, plots and buildings. In particular, the results offer insight into patterns between the types (i.e. which types are found in combination and which not) and provide a new large scale comparative analysis across five European cities. To conclude, a link between quantitative analysis and theory is established, by testing two well-known theoretical propositions in urban morphology: the concept of the burgage cycle and the theory of natural movement.

Quantitative comparison of cities : Distribution of street and building types based on density and centrality measures

- It has been argued that different urban configurations-planned vs. organic, treelike vs. grid like-perform differently when it comes to the intensity and distribution of pedestrian flows, built density and land uses. However, definitions of urban configurations are often rather abstract, ill-defined and at worse end in fixed stereotypes hiding underlying spatial complexity. Recent publications define morphological typologies based on quantitative variables (e.g. Barthelemy, 2015; Serra, 2013a; Gil et al., 2012; Berghauser Pont and Haupt, 2010) and solve some of these shortcomings. These approaches contribute to the discussion of types in two ways: firstly, they allow for the definition of types based on multiple variables in a precise and repeattable manner, enabling the study of large samples and the comparison between both cities and regions; secondly, they frame design choices in terms of types without being fixed and so open up for design explorations where the relation between the variables can be challenged to propose new types. This paper explores the typologies defined by Serra (2013a) and Berghauser Pont and Haupt (2010) further, as these target two of the most important morphological entities of urban form, namely the street network and the building structure. The purpose is to gain a better understanding of how types are composed and distributed within and across different cities. The method is based on GIS and statistical modeling of four cities to allow for a comparative analysis of four cities: Amsterdam, London, Stockholm and Gothenburg. For the street network, we process the Road-Centre-line maps to obtain a clean network model, then run segment angular analysis to calculate the space syntax measures of betweenness at different metric radii, defining the "centrality palimpsest" (Serra, 2013a). For the building structure, we process elevation data to obtain building height, then run accessible density analysis for all building density metrics (FSI, GSI, OSR, L) using the Place Syntax Tool (Berghauser Pont and Marcus, 2014). The street and building types are defined using cluster analysis (unsupervised classification), following a similar approach to Serra (2013a). The result is a typology of street ('paths') and building types ('places'), with different profiles of centrality and density across scales. The spatial distribution and frequency of these types across the four cities gives an objective summary of their spatial structure, identifying common as well as unique traits.

Combining environmental and social dimensions in the typomorphological study of urban resilience to heat stress
- 2022
-
Ingår i: Sustainable Cities and Society. - : Elsevier BV. - 2210-6707. ; 83
-
Tidskriftsartikel (refereegranskat)abstract
- Over the past years, cities have become more prone to extreme and frequent heatwaves. In this regard, urban form plays an important role and several typomorphological classifications have been developed to describe the urban form characteristics that can exacerbate heat stress and influence people's health and comfort negatively (i.e. the environmental dimension of heat-stress resilience). Nevertheless, evidence from past heatwave disasters indicates that other urban form characteristics, not included in existing typomorphological classifications, can significantly affect heat-stress resilience by influencing the conditions of social interaction and the state of social ties and solidarities in urban neighborhoods (i.e. the social dimension). Therefore, this paper proposes a broader approach combining the aforementioned environmental and social dimensions in the classification of urban form types; and demonstrates its application in a real-world case by developing a data-driven typomorphological classification that complements existing ones with the missing social dimension. The results showed the possibility of numerically identifying neighborhood types that, through distinct urban form characteristics, have different potentials for enhancing the social dimension of heat-stress resilience. This has direct planning and design relevance as the quantifiable characteristics of these types can be translated into guidelines/rules and incorporated into local regulations/codes.

The suitability of the urban local climate zone classification scheme for surface temperature studies in distinct macroclimate regions
- 2021
-
Ingår i: Urban Climate. - : Elsevier BV. - 2212-0955. ; 37
-
Tidskriftsartikel (refereegranskat)abstract
- The Local Climate Zone (LCZ) classification scheme, initially designed to distinguish between standard built (urban) and non-built (land cover) types in terms of screen-level air temperature relevant for urban heat island (UHI) studies, has been widely used for land surface temperature (LST) and surface urban heat island (SUHI) studies. However, some concerns remain about the global suitability of the scheme for LST and SUHI studies in different macroclimate regions. By analyzing and comparing a large number of representative LCZ sites and multi-year remotely-sensed LST data, the aim of this work is twofold. Firstly, to study the suitability of the LCZ scheme, with a focus on the built types, for surface temperature studies in four distinct macroclimate regions, namely, the tropical, the arid, the temperate and the cold. Secondly, to understand the influence of the macroclimate region on the LST and SUHI characteristics of the standard LCZ built types. Results show that the urban LCZ standard scheme is applicable, with varying degrees, to all macroclimate regions other than the arid, where a LCZ subclassification might be essential. Also, it has been demonstrated that most LCZ built types exhibit significantly different LST and SUHI characteristics across the remaining macroclimate regions.

- Suburban space has traditionally been understood as a formless remnant of physical city expansion, without a dynamic or logic of its own. Suburban Urbanities challenges this view by defining the suburb as a temporally evolving feature of urban growth.Anchored in the architectural research discipline of space syntax, this book offers a comprehensive understanding of urban change, touching on the history of the suburb as well as its current development challenges, with a particular focus on suburban centres. Studies of the high street as a centre for social, economic and cultural exchange provide evidence for its critical role in sustaining local centres over time. Contributors from the architecture, urban design, geography, history and anthropology disciplines examine cases spanning Europe and around the Mediterranean.By linking large-scale city mapping, urban design scale expositions of high street activity and local-scale ethnographies, the book underscores the need to consider suburban space on its own terms as a specific and complex field of social practiceLaura Vaughan is Professor of Urban Form and Society at the Bartlett School of Architecture, University College London. In addition to her longstanding research into London’s suburban evolution, she has written on many other critical aspects of urbanism today.

Streets for co-presence? : Mapping potentials

Konferensbidrag (refereegranskat)abstract
- In times of increasing residential segregation in cities the potential for interplay between local inhabitants and non-‐locals in urban public space becomes increasingly important. By sharing space we gain information and knowledge from our fellow citizens (Granovetter, 1983), and are enabled to participate in processes that negotiate social structures, attitudes, norms and acceptable behaviours (Giddens, 1984; Zukin, 2005). From this point of departure streets as well as local squares and centres appear to have a key role providing an arena for interplay between different social groups and an arena for exchanging information and are seen as crucial for providing access to opportunities and various urban resources (Young, 1996). Many neighbourhoods, however, have proved to fail in this respect and in areas that today face problems related to social exclusion in Sweden the streets are often characterized by co-‐absence rather than co-‐presence and there is an evident ruptured interface between locals and non-‐locals (Legeby, 2013). We argue that patterns of co-‐presence to a large extent are influenced by urban form and by the morphological properties that also is related to what kind of non-‐residential activities are likely to emerge locally. This paper aims to highlight the critical role of public space and demonstrate how configurational properties may be analysed and described so that it becomes clear if and where urban design interventions can be used in order to create more favourable conditions and improve access to both various urban resources and to an urban life with a mix of locals and non-‐locals. In a project conducted in collaboration with the city of Gothenburg seven neighbourhoods are analysed according to the potential for co-‐presence in public urban space, and according to access to urban resources; two aspects identified as highly relevant from an urban segregation perspective. This paper uses a three pronged approach that combines configurational analysis, accessibility analysis and observations, and various diagrammatical representations of the results are presented. The findings establish that several of the neighbourhoods prove to hold unfavourable conditions as a result of their spatial configuration. Nevertheless, the study illustrates a way forward whereby public planning can be supported by socio-‐spatial analysis and more accurately operate by using urban design to reach more equal living conditions and overcome social exclusion.

Squares for co-presence : The influence of urban form on the intensity and diversity of people co-present in 12 squares in Gothenburg

Konferensbidrag (refereegranskat)abstract
- Increasing residential segregation in cities gives public spaces a more important role in solidarity processes, bringing people together, supporting movement, co-presence and co-awareness. Local squares thus have the greatest significance providing an arena for social interplay as people become co-present. Earlier studies showed that high spatial integration plays an important role for the mix of locals and non-locals besides aspects relating to population density and land use. The purpose of this paper is to reach a better understanding whether also more local properties that characterize a square influence co-presence. Further, more squares are added to represent a broader spectrum of neighbourhoods which will help us understand whether network integration is important in all types of neighbourhoods. Thirdly, this study will help to inform whether earlier findings by Legeby in Stockholm, Södertälje and Gothenburg can be confirmed which allows us to generalize these findings. The amount of people co-present in squares and the share of non-local visitors are studied as two indicators (or aspects) of co-presence. The empirical data was collected through observation including snapshots and interviews. The number of people present in the public squares was noted and the interviews were used to measure the share of non-locals. The spatial analysis includes besides integration and betweenness, an analysis of density (both population and building density) and land uses accessible from the squares within various radii. Also, geometric characteristics such as size, shape and enclosure of the squares are included in the study. The result shows different patterns of co-presence in the 12 studied squares, especially if we distinguish squares in the most central area of Gothenburg with squares located at a longer distance from the city centre. Some findings confirm earlier findings and allow us to generalize the findings as other findings seem not to be relevant in all cities. Further, pure geometric properties of squares do not show strong correlations with co-presence. We can thus conclude that the local design intervention of squares cannot promote co-presence very well without the support of urban structure.

Development of a measure of permeability between private and public space
- 2018
-
Ingår i: Urban Science. - : MDPI AG. - 2413-8851. ; 2:3
-
Tidskriftsartikel (refereegranskat)abstract
- This article focuses on the development of a measure for frontage permeability, which we argue is needed to complement existing metrics used to describe urban environments and assess, amongst others, social performativity. Built density and street network centrality are two characteristics often discussed in relation to urban vitality. However, high densities and high centrality do not always result in higher urban vitality, which can be partially explained by a typical densification model often used in Brazil and in some other Latin-American cities with high-rise residential buildings. To understand the relation between urban form and social performativity, the metrics for density and network centrality are thus not sufficient and we propose to add two other urban form properties: frontage permeability and plot size. The hypothesis is that the mentioned densification model combines higher density with larger plots and lower permeability. Many scholars have shown that higher density is often associated with increased urban vitality, but larger plots are said to have the opposite effect and in Latin American cities, it is observed that lower vitality is found where buildings have less permeable frontages. This research aims at studying the combined effect of density, permeability, and plot size on urban vitality or, more generally, social performativity. However, there is no well-developed method to measure frontage permeability. Therefore, this article first presents a method to measure frontage permeability, both in qualitative and quantitative terms. This measure is then combined with existing measures of density and plot size to analyse how these three urban form metrics relate to each other. In a forthcoming paper, pedestrian observation data will be added to the analysis, to be able to give more insight in the relation between the three urban form metrics and urban vitality using pedestrian counts as proxy. We will show that the developed measure seems to be coherent and effective in describing permeability. Further, the preliminary results confirm the hypothesis that the Brazilian densification model with high-rise residential buildings generates a decrease in frontage permeability, although it does not appear to significantly change plot sizes.

A multi-scale approach in the planning and design of water sensitive environments

Ingår i: Proceedings 8th International Conference NOVATECH Lyon.
-
Konferensbidrag (refereegranskat)abstract
- A spatial analytical framework to support landscape planning and urban design practices was introduced in this study aiming to integrate different scales of analysis and their effect when retrofitting Water Sensitive Urban Design (WSUD) in the existing urban environment. The multi-scale analyses are performed using a geographic information system (GIS) platform to capture landscape patterns (spatial structure and composition) and processes (e.g. water cycle). The macro-scale analysis at the urban catchment level allows the development of planning strategies and performance objectives for the urbanized landscape, whilst the meso-scale, comprising the ecological (green) corridors, connects core areas conveying surface flows across the sub-catchments. At the neighbourhood scale, urban form parameters measured the territorial depth (permeability) between public and private land and the suitability of each site to retrofit Water Sensitive Urban Design. The feasibility to improve or extend the existing green-blue landscape matrix is assessed, and its implications discussed, by using a sequence of landscape metrics, land suitability and network analysis techniques. The study focused on modelling opportunities for the introduction of landscape features designed to improve surface stormwater management and, at the same time, provide multiple ecosystem services.

- One of the current dominant strategies proposed for sustainable urban development is densification. UN Habitat prescribes a density of over 150 inhabitants per hectare to realize the UN Sustainable Development Goals. While some authors advocate the very reasonable benefits of density, others emphasize the potential drawbacks. The main goal of this paper is to provide a systematic review of international research on urban density and its potential benefits and drawbacks for sustainable urban development. 1208 articles were selected from Web of Science and after the screening of abstracts, 330 papers were found eligible to be included in the quantitative synthesis. Results show that the effects of densification that dominate literature are transport related studies (41%), followed by studies focusing on economics (14%), social effects (12%) and human health (11%). Least studied effects are resource efficiency (1%), service (3%) and urban environment (4%). Positive correlations with higher density are reported for transport and economics, while ecology, social impact and health show mainly negative correlations with higher density. The findings reported are generic as similar trends are found in North America, Asia and Europe and only minor differences in outcome are found in studies using different measures of density, unit or scale of analysis.

Bokkapitel (övrigt vetenskapligt/konstnärligt)abstract
- The focus of space-morphology, a specific branch in urban morphology, is to ‘uncover the fundamental characteristics of urban geometries’ (Moudon in Ordering space: types in architecture and design. Van Nostrand Reinhold, New York, p. 289–311, 1992) and ‘enrich the description of built form in ways that express aspects of performance and function’ (Peponis in Investigative modeling and spatial analysis: a commentary of directions. p. 2, 2014). Two research directions are important when discussing space-morphology, both developed in the UK during the 1970s. First, the work at the Centre of Land Use and Built Form at Cambridge University directed by Leslie Martin and Lionel March and their seminal work ‘the grid as generator’ (Martin and March in Urban space and structures. Cambridge University Press, Cambridge, 1972). Recently, this direction received renewed attention with publications such as ‘Streets & Patterns’ by Marshall (Urban Des Int 17:257–271, 2005) and ‘Space, density and urban form’ by Berghauser Pont and Haupt (Spacematrix: space, density and urban form. NAi Publishers, Rotterdam, 2010). Second, the Unit for Architectural Studies at University College London, directed by Bill Hillier, that developed in what we today know as the Space Syntax laboratory. Besides the description of these two directions in what we call space-morphology, this chapter will discuss how these two directions can be combined and how this can benefit the other schools of urban morphology, not least when it comes to identifying typologies. Typologies, being specific combinations of spatial properties, perform and function in specific ways and can be an effective way to inform urban design and planning practice when they intervene in cities and change these types or add new ones. Such an evidence-based approach puts new demands on the education of architects, urban planners and designers.

Tidskriftsartikel (refereegranskat)abstract
- A better understanding of the relationship between the built environment and urban processes is central in guiding urban processes in more sustainable trajectories. Of particular importance to this endeavour is the idea of urban types. However, on closer scrutiny, while such types may capture the symbolic dimension of urban form, they frequently do not capture its performance or functional dimension. This prohibits precise policy formulation on the topic. This paper first presents a methodology for generating urban types relevant to urban practice (using analytical and statistical methods) and, second, an empirical test of the differences in performance concerning their influence on the presence of people in public space (an essential driver of many other urban processes). For this reason, a large (and to our knowledge unique) pedestrian survey of three European metropolitan areas was conducted and used to test the performance of the urban types developed. The results prove that the methodology for developing the types is robust, as it picks up generally recognised spatial patterns in all three cities. Further, the types were able to explain the intensity of pedestrian flow, its spatial distribution and fluctuations of intensity in space and time. These are vital steps forward and provide more useable typologies in urban planning and design practice.

Förtätning av stationsnära områden för god tillgänglighet. Utveckling av en analys - och utvärderingsmetod
- 2022
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- Det finns en vilja att förtäta i närheten av stationer för att öka användningen av kollektivtrafik och därmed minska klimatpåverkan kopplad till transpor- ter. Förtätning bidrar bland annat till att skapa levande stationssamhällen, med blandade funktioner, god tillgäng- lighet och miljöer som är trygga och vistelsevänliga där olika grupper och behov möts. Potentialerna är många men så även utmaningarna. Förtätning av stationsnära områden kan också leda till oönskade konsekven- ser för social, ekonomisk och ekologisk hållbarhet. Den här rap- porten kan förhoppningsvis ge ökad förståelse för förtätning i relation till regional tillgänglighet samt för positiva och negativa konsekvenser av förtätning i stationsnära områden. Den kan också skapa insikter om hur olika alternativ för utveckling av stations- nära områden kan värderas utifrån Agenda 2030, särskilt Mål 11: Hållbara städer och samhällen. Rapporten är framtagen inom projektet Urbana stationssamhäll- en – förtätning av stationsnära områden för god tillgänglighet (2020–2022) som finansierats av Trafikverket och bedrivits i sam- verkan mellan Urban Futures vid GMV (projektägare), Arkitektur och samhällsbyggnadsteknik vid Chalmers tekniska högskola, Gö- teborgsregionen (GR), Samhällsplanering vid Högskolan Dalarna och Samhällsplanering och miljö vid KTH.

Increasing cities' capacity to manage noise and air quality using urban morphology

Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- According to the World Health Organization, the top two in disease burden are air pollution and environmental noise. In cities, road traffic is the largest contributor to both noise and air pollution and the corresponding Swedish Environmental objectives are to date estimated to not be reached by 2020. Future reductions concerning both air quality and noise are considered insufficient whereby additional measures are needed. Air quality is linked to urban form such that compact cities were shown to result in increasing concentrations of air pollution. Further, urban form influences the meteorology due to changed surface roughness on the larger scale (urban scale), and even more in a local- and microscale at ground level in street canyons. This will affect wind patterns influencing the dispersion possibility of air pollutants. For investigating local effects of urban morphology on noise and air distribution simultaneously, the Spacematrix method has been shown to be useful, as described in Berghauser Pont and Haupt (2010). Building types can be composed of a combination of density variables enabling to quantify a type and manipulate each variable separately. The aim of this paper is to identify critical spatial parameters influencing noise and air pollution and translate them into measures of spatial form including size of the urban block, and distribution, positioning and height of the buildings within that block.

- Although density has been an important concept for urban design and planning ever since the 19th century, it is an imprecise concept with varying definitions and measurements. This is annoying as the concept is central to strategies for sustainable urban development which have gained wide support since the 1990s. This paper gives a brief review of the most frequently used urban density measures and their shortcomings. In this paper, we will further show that a multivariable definition of density as proposed in the Spacemate method is needed to capture important morphological qualities that otherwise are lost in abstract numbers. The paper also addresses the Modifiable Area Unit Problem inherent to all measures of urban density, and proposes to solve this by introducing accessibility in the density measure. Defining distance is obviously a critical part of the accessibility measure and it is therefore proposed to use the axial map developed in space syntax, to measure distance. The axial map is a geometric representation of urban space based on graph theory, constructed from the point of view of a cognitive subject, i.e. an experiencing and acting human being. By doing so this paper arrives at a measure of accessible density that even can be understood as a measure of perceived density.

INTEGRATED URBAN ENVIRONMENT EFFECT ANALYSIS OF INFRASTRUCTURAL TRANSFORMATIONS
- 2022
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- The report presents the method developed within the research project ‘Stadsmiljöanalys- Analys av tätbebyggda miljöer i infrastrukturprojekt’, funded by Trafikverket (Swedish Transport Authority). This project sets up an integrated methodology for analysing and estimating the local impact of road and rail infrastructure projects in urban environments, either by way of new infrastructure or by way of retrofits, focusing on socioeconomic, environmental, and cultural-historical effects. While the focus is on national transport infrastructure investments, the method addresses local effects. This stems from the acknowledgement that each infrastructure investments results in a redistribution of accessibility where increasing accessibility on a regional and interurban scale might create encroachments on a local scale including the reduction of the usability of areas near to the infrastructure due to emissions and noise, risk of accidents, negative impacts on wildlife as well as barrier effects. It is these encroachments this method aims to highlight with the aim to reduce negative trade-offs of new or transformed transport infrastructure and recognize both local opportunities and sensitivities. In this project the direct effects of infrastructure projects in relation to the three perspectives (socioeconomic, environmental, and cultural-historical are described and measured in a precise manner through a series of spatial analyses. The cumulative, indirect, effects and broader consequences are also assessed, in relation to the sustainable development goals. The overall assessment methodology is based on a before-and-after analysis workflow, systematically comparing the existing situation (how it is, how it functions, how it affects people) to the future scenarios proposed by planning. The methodology is showcased using two infrastructural transformations projects in Söderköping and Mölndal, Sweden, as case studies. The overarching goal of the research project is to contribute to an improved integration between infrastructure and local urban areas and communities in projects initiated and developed by the Swedish Transport Authority, Trafikverket. The presented methodology builds on the ILKA (Integrerad landskapskaraktärsanalys) method, currently used by the Swedish Transport Authority. While ILKA focuses mainly on the inventory of the current landscape on a regional scale, this project widens the scope to also address urban areas and to include, besides the ecological descriptions, also socio-economic and cultural-historical analysis that are currently less emphasized. Such an integrated method can improve the ability of the Swedish Transport Authority to develop projects that contribute to sustainable urban development and, furthermore, create a unified work procedure in the organization.

Konferensbidrag (refereegranskat)abstract
- Interest in urban green areas has rapidly increased in recent years as the world becomes increasingly urbanized (see e.g., McDonald, 2008, UN-habitat, 2016). This brings new demands for a deeper understanding of the morphology of green areas in cities that provide us with a range of important ecosystem services (ESS) such as evaporative cooling, water purification, micro climate regulation, recreation and even pollination (MA 2005; Andersson et al., 2007). If we also are to support or even enhance such services, we need to make this knowledge accessible for professionals in urban planning and design. In both regards we see the need to bring the fields of landscape ecology and urban morphology closer to each other. This papers addresses this, taking the ESS pollination as point of departure. It has been acknowledged that besides the amount of green, also connectivity between green areas is important for most of these ESS (Alberti, 2008; Kindleman et al., 2008). The critical issue remains how connections are represented. In this paper we propose an alternative approach inspired by space syntax where we introduce a method to capture urban form and their impact on movement behaviour of bumble bees. A first attempt to do so was discussed by Marcus et al. (2014) but instead of drawing connections using space syntax, we here propose to define the resistance to movement using visibility graph analysis (VGA). The level of visual integration can then be calculated based on the number of visual steps it takes to get from one point to any other point within the system. For species that navigate by sight this can be a rather simple and effective way to measure the cost or resistance to move through an urban landscape. To test the method, observation data on bumble bees collected in 16 sites in Stockholm (Ahrné et al., 2009) are used.

- Inom stadsbyggnad har högre täthet blivit lösningen på det mesta. Utan tvekan finns det tydliga fördelar såsom ökat underlag för handel och kollektivtrafik, sparad mark utanför städerna, och innovationsfördelar (Ahlfedt et al. 2017). Detta har lett till riktlinjer för hållbar stadsutveckling som FN Habitat (2014) sprider där en hög täthet är en av fem föreslagna stadsbyggnads-principer.

Konferensbidrag (refereegranskat)abstract
- Typologies play a role in urban studies since a long time, but definitions are often rather abstract, ill-defined and at worst end in fixed stereotypes hiding underlying spatial complexity. Traditional typologies are focussing on separate elements, which allow for understanding crucial differences of one spatial feature in greater detail, but lack the capacity to capture the interrelation between elements. Further, they often focus on one scale level and therefore lack to acknowledge for interscalarity. Recent publications define morphological typologies based on quantitative variables, building on the seminal book ´Urban Space and Structures´ by Martin and March, published in 1972, but using more advanced spatial analysis and statistics. These approaches contribute to the discussion of types in two ways: firstly, they define types in a precise and repeatable manner allowing for city-scale comparisons; secondly, they acknowledge cross-scale dynamics important for e.g. living qualities and economic processes where not only the local conditions are important, but also the qualities in proximity. This paper focuses on the comparison of building types in three Swedish cities, using the multi-variable and multi-scalar density definition. A statistical clustering method is used to classify cases according to their measured similarity across the scales. The results show that working with types is a fruitful way to reveal the individual identity of these types, compare cities and highlight some differences in the way the three cities are structured.

Sustainable Urban Form
- 2012

Ingår i: High-Rise and the Sustainable City. - 9789085940494 ; , s. 76-91

Bokkapitel (övrigt vetenskapligt/konstnärligt)abstract
- The search for more sustainable urban patterns is at the core of this article. Often, this discussion does not go further than a discussion concerning compact cities versus sprawl. Starting from the importance of higher densities, this article explores the subject of density in relation to urban form much deeper by looking into a variety of performances. Issues that will be discussed are, amongst others, the role of density in terms of daylight access, urbanity (or urban vitality) and CO2 emissions. We will see that performances often contradict each other and finding the most sustainable solutions is a question of optimizing all of them simultaneously. The Spacematrix method (Berghauser Pont and Haupt 2010) will be used as a starting point to do so.

Systematic review and comparison of densification effects and planning motivations
- 2021

Ingår i: Buildings and Cities. - : Ubiquity Press, Ltd.. - 2632-6655. ; 2:1, s. 378-401

Tidskriftsartikel (refereegranskat)abstract
- Do higher urban densities contribute to more sustainable cities and communities? This paper examines the effectiveness of higher density (as a means) for achieving sustainable urban development (the goal) following three lines of enquiry. First, a systematic review of the scientific literature (n = 229 peer-reviewed empirical studies) is presented on the effects of urban density. Second, the motivations for increasing urban density are studied in a systematic review of Swedish planning practices based on the comprehensive urban plans in 59 municipalities. Third, these two studies are compared to find matches and mismatches between evidence and practice. Although positive effects exist for public infrastructure, transport and economics, there are also considerable negative environmental, social and health impacts. This creates a challenging task for urban planners to assess the trade-offs involving densification and accommodate current urbanisation rates. Some topics are found to be over-represented in research (transport effects), seldom discussed in practice (environmental impact), and misaligned when comparing motives and evidence (social impact). Furthermore, for some topics, urban density thresholds are found that are important because they may explain some of the divergences in the results between studies. PRACTICE RELEVANCE The transfer of knowledge from research to planning practice is a serious concern as planning strategies are not aligned with scientific evidence. Planning practice in Sweden is more positive about the contribution of higher density to sustainable urban development than the results of empirical studies warrant. The largest deviation is found in relation to the social impacts of higher density where the planning arguments are not aligned with the evidence. Several reported negative effects of densification (e.g. water management, recreational infrastructure, biodiversity) are not sufficiently accounted for in Sweden’s planning policy and strategy. The narrow planning focus on decarbonising cities and densification needs to be broadened to ensure cities are resilient against the effects of climate change and include mitigation strategies to reduce negative social, environmental and health impacts. The findings can be used to develop evidence-based planning strategies. Other countries can apply this process to assess their planning strategies.
