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

    • 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.

  • Quantitative comparison of cities : Distribution of street and building types based on density and centrality measures
  • 2017
  • Ingår i: Proceedings - 11th International Space Syntax Symposium, SSS 2017. - : Instituto Superior Tecnico, Departamento de Engenharia Civil, Arquitetura e Georrecursos. - 9789729899447 ; 2, s. 44.1-44.18

    • 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.

  • The spatial distribution and frequency of street, plot and building types across five European cities
  • 2019
  • Ingår i: Environment and Planning B-Urban Analytics and City Science. - : SAGE Publications. - 2399-8083 .- 2399-8091. ; 46:7, s. 1226-1242

    • 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.

  • 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.
