Amsterwarm:

Amsterwarm biedt met de ontwikkeling van een gebiedstypologie inzicht in het stedelijk warmte-eiland effect in de stad Amsterdam.  De typologie maakt duidelijk in hoeverre de stad Amsterdam zelf bijdraagt aan het stedelijk warmte-eiland effect, in hoeverre buurten en woningen hun bewoners blootstellen aan het warmte-eiland effect, en in hoeverre de bewoners van de stad kwetsbaar zijn voor de gevolgen ervan.  De typologie is gebaseerd op het ruimtegebruik fysieke kenmerken van Amsterdam, op de leefbaarheid en de woningkwaliteit, en op de samenstelling van de bevolking in de verschillende delen van de stad.  De typologie geeft concrete handreikingen voor het soort actie die de stad Amsterdam kan ondernemen met oog op het welzijn en het comfort van haar bevolking, en met oog op het beperken van het energiegebruik om gebouwen te koelen tijdens warm weer.  De gebiedstypologie maakt het mogelijk om uitspraken te doen over specifieke maatregelen/prioriteiten voor verschillende delen van de stad Amsterdam.  Amsterwarm verkent tevens hoe sterk het warmte-eiland Amsterdam is

Understanding European Regional Diversity - Lessons learned from Case Studies

The content of this report is a deliverable to the FP 7 project RUFUS (Rural future Networks) concerning the case studies made within the project. As a deliverable in a EU framework project it reports extensively on the methods and empirical data collected in the project’s case studies. The work has as an overarching motive to translate research findings into implications that are relevant for policy makers in the EU. The conclusions from the case studies are therefore of two types – the findings made and the implications they might give for policy making within the field of rural development

Comparing the Landscape Fragmentation and Accessibility of Green Spaces in Territories-in-Between across Europe

To improve the positive effects provided by green spaces on human well-being in dispersed urban areas is a key challenge for sustainable spatial development in Europe. This article presents a methodology that allows for the comparison of the potential of green spaces in Territories-in-Between across Europe, in a way that crosses the fields of urban ecology and urbanism. The article adds to the existing knowledge and understanding of the relation between the spatial organisation of systems of green spaces and their accessibility to biodiversity and human well-being. Firstly, it adapts the fragmentation index in a way that it can be applied to the specific spatial characteristics of Territories-in-Between. Secondly, it combines the fragmentation index with an indicator for accessibility of green spaces, in order to integrate aspects of ecology, human well-being and the spatial heterogeneity of the relation between them. The methodology is applied to ten areas across western Europe in order to inform decision and policy makers including urban planners, designers and environmental agencies to be able to assess the potential of system of green spaces for biological diversity and human well-being in an integrated manner.Environmental Technology and Desig

Challenges for circular urban development

A shift towards a more Circular Economy is, in many policies, seen as crucial to achieving a more sustainable andinclusive built environment that meets future demands.In the last decade, the European Commission’s researchfunding has supported numerous initiatives aiming to reducewaste generation through shifts towards Circular Economyapproaches. Many cities and regions followed and startedto develop circular economy strategies, action plans andcircularity monitors. The difficulties and challenges of implementing a seemingly simple concept are mainly to narrow,slow down and close materials streams and thereby reduceour dependency on raw material input. Europe’s geopoliticaldependency on resource-rich countries has become very apparent during the last years. In this article, we identify someof those challenges and propose potential ways forward.Real Estate ManagementEnvironmental Technology and Desig

Investigating functional mix in Europe's dispersed urban areas

A large proportion of European inhabitants live in dispersed urban settlements, much of which is labelled as sprawl, defined by monofunctional, low-density areas. However, there is increasing evidence that this may be an overly simplistic way of describing territories-in-between (TiB). This paper defines and maps functional mix in six dispersed urban areas across Europe, applying a method that goes beyond existing land-use-based mixed-use indicators but considers functional mixing on the parcel level. The paper uses data on the location of economic activities and the residential population. It concludes that, in eight cases from four European countries, mixed-use is widespread and that more than 65% of inhabited areas are mixed. Moreover, the paper relates functional mixing to specific settlement characteristics: permeability, grain size, centrality and accessibility, and connectivity. This demonstrates that functional mixing is not the result of local urban morphology or planning instruments, but of the multi-scalar qualities of a location. Therefore, there is a requirement to coordinate planning and design through different scales if mixed-use areas are to be seen as one strategy for achieving greater sustainability in the spatial development of dispersed areas.Environmental Technology and DesignUrban Desig

A literature review and categorisation of sustainability-aimed urban metabolism indicators: a context, indicator, mechanism, outcome analysis

Urban metabolism has been advanced as an approach to quantifying energy and resource use and supply in the modern urban system. It is a multidisciplinary approach focused on providing insight into the behaviour of cities for drafting effective proposals for a more humane and ecologically responsible future.Urban metabolism indicators could play an important role in promoting the science and practice of urban metabolism for sustainability. This paper presents a systematic review of literature centred on defining sustainabilityaimed urban metabolism indicators to improve the integration of urban metabolism and urban sustainability. Furthermore, this paper concentrates on two indicator sets (emergy synthesis and material flow analysis [MFA]), examining the relationship between these indicators and the three dimensions of sustainability (environment, economy, and society) in the literature. The paper thus buildsa bridge between urban metabolism and urban sustainability in the hope that urban metabolism indicators can be used to measure and assess urban sustainability

A bottom-up ontology-based approach to monitor circular economy: Aligning user expectations, tools, data and theory

With circular economy being high on governmental agendas, there is an increasing request from governing bodies for circularity measurements. Yet, currently existing macro-level monitoring frameworks are widely criticized for not being able to inform the decision-making. The criticism includes, among others, a lack of consensus on terminologies and definitions among scholars, politicians, and practitioners, a lack of supporting data and tools and, consequently, a lack of transparency and trustworthiness. To address those needs, a bottom-up approach to build a shared terminology is suggested as a starting point for monitoring development. The government, data providers, and tool developers are involved in the process of formal ontology development and alignment. The experiment builds upon a use case of the Amsterdam Circular Economy Monitor (2020). First, four ontology development approaches are used to create a theory-centered, a user-centered, a tool-centered, and a data-centered ontology. The ontologies are later compared, merged, and aligned to arrive at one single ontology which forms the basis of the circular economy monitor. The notes taken during the process have revealed that next to a material flow model, typical of socioeconomic metabolism analysis, policy makers are concerned with actors (i.e., institutions, companies, or groups of people) who participate in the analyzed processes and services. Furthermore, a number of terms used by the decision-makers lack clear definitions and references to be directly associated with the available data. Finally, a structured terminology alignment process between monitor users, developers, and data providers helps in exposing terminology conflicts and ambiguities.</p

Hotterdam: Mapping the social, morphological, and land-use dimensions of the Rotterdam urban heat island

Climate scientists forecast that heat waves will occur more often in the Netherlands in the coming decades. The Hotterdam study accordingly measured urban heat and modelled the surface energy balance in the Dutch city of Rotterdam. It identified in detail the city’s social, morphological, and land-use dimensions using a geographic information system (GIS), 3D models, and satellite images. It used hierarchical and multivariate regression analyses to determine the links between temperatures and the surface energy balance on the one hand, and social, morphological, and land-use aspects on the other. The Hotterdam study did establish a link between the urban heat island effect in Rotterdam and the health of its population. It also statistically explained the high rate of mortality among seniors seventy-five and over during the summer of 2006. The spatial concentration of senior citizens, the average age of the buildings they live in, and the sum of the sensible heat flux and storage heat flux play a large role. Imperviousness, the leaf area index, the building envelope, surface water, and shade are the dimensions that best explained the Rotterdam urban heat island. We mapped these aspects in two heat-maps that help in setting priorities for implementing climate adaptation measures.100% ResearchOLD Urban DesignEnvironmental Technology and Desig

Haagse Hitte: Het Haagse warmte-eiland in kaart gebracht

De afgelopen jaren zijn verschillende studies verricht naar het warmte-eiland effect in Nederland. Een studie van TNO (TNO, 2012) heeft voor wat betreft Den Haag de toon gezet. Den Haag zou van alle Nederlandse steden het sterkste warmte-eiland effect kennen. Die beeldvorming heeft gezorgd voor een maatschappelijke en politieke bezorgdheid die het vertrekpunt vormt voor dit Haagse Hitte onderzoek van de TU Delft, mede mogelijk gemaakt door de gemeente Den Haag. Bij het onderzoek hebben we ons de volgende vragen gesteld:- Is het warmte-eiland effect in Den Haag inderdaad fors sterker dan in naburige steden?- Welke stadsdelen van de gemeente Den Haag zijn het sterkst getroffen door het zomerse hitte-eiland effect?- Wordt het warmte-eiland effect in Den Haag veroorzaakt door het ruimtegebruik? En zo ja, welk ruimtegebruik legt hier het meeste gewicht in de schaal?- In juli 2006 trad er als gevolg van de extreme hitte een verhoogde sterfte op in Den Haag. Is de ruimtelijke spreiding van de sterfte gedurende die maand mede te verklaren aan de hand van het warmte-eiland effect?- Is er voldoende aanleiding voor de stad Den Haag om actie te ondernemen ten aanzien van het stadsklimaat? En zo ja, moeten dan bepaalde delen van de stad eerder aangepakt worden dan andere? Welke adaptieve maatregelen moeten we daar nemen om het warmte-eiland effect verminderen?100% ResearchOLD Urban DesignEnvironmental Technology and Desig
