O pagamento por serviços ecossistêmicos como instrumento de gestão ambiental para o espaço urbano / Payment for Ecosystem Services as an environmental management tool for urban space.

Fernando Antonio Tolffo 14 October 2015 (has links)
Por suas dinâmicas sociais e territoriais complexas, as metrópoles estão sujeitas aos graves impactos causados por eventos climáticos extremos, reais ou esperados. Organismos internacionais multilaterais e extensa literatura acadêmica avalizam a importância do papel dos ecossistemas para a redução dos riscos e na mitigação das consequências dos desastres ambientais, tanto em áreas rurais como urbanas. Propõe-se a valoração das áreas verdes livres e dos parques urbanos como recurso que integre estratégias para o desenvolvimento da qualidade ambiental das cidades através dos serviços ecossistêmicos derivados da cobertura arbórea local, divisando-se a manutenção da saúde pública em um meio ambientalmente equilibrado. Foi aplicada ferramenta tecnológica representada pelo software i-Tree como método empregado para a identificação, quantificação e estimativas de valoração econômica dos serviços ecossistêmicos prestados pelas árvores contidas no Parque Ibirapuera, em São Paulo, que serviu como referência. É discutida a significância da inserção dos princípios e objetivos do instrumento do Pagamento por Serviços Ecossistêmicos no planejamento, ordenamento e gestão urbanos, integrando-o a políticas de melhoria da saúde ambiental nas cidades. / For their complex social and territorial dynamics, the cities are subject to the severe impacts of extreme weather events, actual or expected. Multilateral international organizations and extensive academic literature endorse the important role of ecosystems to reduce risks and mitigate the consequences of environmental disasters, both rural and urban areas. It is proposed to valuation the green areas and urban parks as a resource that integrates strategies for the development of environmental quality in cities through the ecosystem services derived from local tree cover, for the purpose of maintenance of public health. Was applied technological tool represented by i-Tree software as a method used to identify, quantify and estimate the economic value of ecosystem services provided by trees contained in Ibirapuera Park, in São Paulo, which served as a reference. Discussed the relevance of the integration of the principles and objectives of the instrument Payment for Ecosystem Services in urban planning and management, integrating it in policies to improve environmental health in cities.

Diretrizes para projetos de loteamentos urbanos considerando os métodos de avaliação ambiental. / Project guidelines for urban settlements considering environmental assessment methods.

Iara Negreiros 08 April 2009 (has links)
A exemplo dos diversos métodos desenvolvidos mundialmente para avaliação de sustentabilidade no âmbito do edifício isolado e seus sistemas constituintes, surgem no horizonte novos sistemas de avaliação que consideram: o entorno, a vizinhança, o loteamento como um todo, enfatizando aspectos de desenvolvimento sustentável combinados às práticas dos chamados edifícios verdes, tais como o Leadership in Energy and Environmental Design for Neighborhood Developments Rating System (LEED-ND), desenvolvido nos Estados Unidos; o Approche Environnementale de lUrbanisme (AEU), desenvolvido na França; o Global Reporting Initiative (GRI) Sustainability Report Guidelines, desenvolvido pela ONU; entre outros. Enquanto aumenta a legitimidade do paradigma da sustentabilidade e sua pertinência para lidar com a especificidade do urbano, cresce a necessidade de selecionar critérios, estratégias e indicadores mensuráveis para ancorar a formulação, monitorar a implementação e avaliar os resultados das políticas urbanas em bases sustentáveis, de acordo com as diretrizes propostas pelas Agendas 21 Global e Brasileira. Por outro lado, o crescimento urbano das últimas décadas tem ocorrido de forma dispersa, por processos de deslocamento de atividades tipicamente urbanas para o campo, observado pela disposição das manchas urbanas nas imagens de satélites, que se dispõem como uma série de polos urbanos separados por vazios rurais. Inserido neste contexto da chamada urbanização dispersa, o parcelamento do solo através de loteamentos é uma das tipologias de expansão da área urbana que acarretará em significativas implicações na paisagem e, consequentemente, na atividade de gestão e planejamento urbanos. Portanto, com o objetivo geral de identificar, analisar e recomendar diretrizes para projetos de loteamentos urbanos, esta pesquisa realiza uma análise crítica qualitativa e comparativa dos diversos métodos de avaliação ambiental existentes nacional e internacionalmente, através de estudo de caso em um loteamento residencial, o Projeto Gênesis, em Santana do Parnaíba, município da Grande São Paulo. O resultado é um conjunto de diretrizes para auxiliar o processo de projeto de loteamentos urbanos considerando os requisitos e critérios dos métodos, contribuindo também para o aperfeiçoamento da legislação urbanística por parte dos agentes do poder público. / As many world-wide developed assessment methods for sustanability of isolated buildings and their constituting systems performance, new environmental assessment systems have recently been proposed, taking into account neighborhood, land sub-division and urbanistic issues. They integrate principles of smart growth, sustainable development and green building, such as Leadership in Energy and Environmental Design for Neighborhood Developments Rating System (LEED-ND), developed in the United States; Approche Environnementale de l\'Urbanisme (AEU), developed in France; Global Reporting Initiative (GRI) Sustainability Report Guidelines, developed by United Nations; and many others. With new sustainability paradigms and difficulties on dealing specifically with sustainable cities grows, there are needs on selecting criteria, strategies and measurable indicators in order to anchoring formulation, controlling implementation and evaluating results of the urban policies in sustainable basis, according to the proposed guidelines of Global and Brazilian Agendas 21. However, in the last decades, the urban growth has happened in a dispersed form, by displacement process of typically urban activities for the rural areas, observed by the urban spots disposal in satellites images, as many urban polar regions separated by rural or open lands. Inserted in this context called \"diffuse urbanization\", the land sub-division by plotting is a model of urban growth that would cause significative impacts in landscape and ecology and, consequently, in the activities of urban planning. Therefore, with the general purpose of identifying, analyzing and recommending guidelines, this paper brings qualitative and comparative critical analysis of the many locally and internationally environmental assessment methods for urban plotting, through a case study methodology for a residential plotting, the Gênesis Project, in Santana do Parnaíba, municipality of São Paulo metropolitan region. The results are a set of guidelines, that considers the requisites and criteria of each method, in order to help designers in urban plotting project process and to contribute the improvement of urban legislation by public agents.

Partindo de uma reflexão sobre valor de significância, autenticidade e sustentabilidade do patrimônio cultural, estudos de conservação integrada são confrontados com o tema acessibilidade, respaldado, por sua vez, em marcos políticos institucionais, acordados por diferentes países em respeito aos direitos universais dos cidadãos. Acessibilidade é compreendida como autonomia, segurança e comodidade, nos espaços e edificações, bem como acesso aos equipamentos urbanos, com direito de ir e vir para o trabalho, lazer, habitação e mobilidade. Assim, o objetivo geral deste trabalho é avaliar dificuldades de compatibilização entre acessibilidade ao meio físico e conservação, investigando uma área histórica da cidade do Recife, o Largo do Carmo, e explorando depoimentos de segmentos sociais que lidam com essa temática. Os depoimentos foram obtidos por meio de questionários específicos elaborados para pessoas com deficiência, para arquitetos e para funcionários públicos do patrimônio cultural. As questões exploraram vivências ou experiências profissionais com o intuito de amplificar aspectos sutis e sensíveis da discussão proposta. O exame da acessibilidade urbanística do entorno do Carmo foi realizado com recursos e procedimentos disponíveis para evidenciar múltiplas dificuldades que afetam as pessoas com deficiência. Além de registros fotográficos, uso do clinômetro e trena, foram utilizados três mapas (UNIBASE) do local e fichas de avaliação que permitem a caracterização do ambiente pesquisado e o levantamento de informações sobre a circulação urbana, o acesso aos lotes e edificações, ao mobiliário urbano e aos transportes, fichas essas elaborada por José Antônio Lanchoti, em 2005. Para investigar a autenticidade dos imóveis históricos integrantes dessa área – a Igreja da Ordem Terceira do Carmo, a Basílica Nossa Senhora do Carmo e o Imóvel Especial de Preservação (IEP nº 59) – vários instrumentos averiguaram suas dimensões: artística, histórica, social e científica. Foram considerados: formas e desenho; substância e materiais; uso e função; tradições e técnicas; localização e espaço; e espírito e sentimento, itens indicados na carta de Veneza de 1964. Utiliza-se também a tabela de autenticidade (Nara-Grid) proposta por Koenraad van Balen, em 2008. Acessibilidade e autenticidade puderam, então, integrar uma Matriz, elaborada por Luís Oscar Ferreira, em 2011, e adaptada para o presente estudo. Ela foi o principal resultado obtido neste estudo, ou seja, um instrumento de intervenção de modo a orientar a adequação da acessibilidade do entorno do Carmo sem prejuízos de seu valor de significância e autenticidade. Além disso, os resultados obtidos a partir dos questionários sugerem a necessidade de cursos sobre acessibilidade para arquitetos que reclamaram de pouca (in)formação recebida na graduação, bem como sugerem oportunidades de debate sobre esse tema, de modo a envolver profissionais da área e pessoas com deficiência, ciosas de seus direitos. Estas podem contribuir com indicações necessárias para o acesso universal aos valores culturais. Conclui-se que é possível conciliar a acessibilidade com a conservação do patrimônio cultural sem prejudicar a autenticidade e quebra-se o simplismo de se considerar o patrimônio intocável, não sujeito à intervenção mínima. / Accessibility for people with disabilities to urban and architectural cultural heritage is the object of this work. From a reflection on significance value, authenticity and sustainability of cultural heritage, integrated conservation studies are confronted with the theme accessibility, based, in turn, on institutional policy frameworks in agreement with different countries as far as universal citizens' rights are concerned. Accessibility is understood as autonomy, safety and convenience, in spaces and buildings, as well as the access to urban facilities, with the right to come and go to work, leisure, housing and mobility. Thus, in general terms, the aim of this study is to evaluate difficulties in reconciling conservation and accessibility to physical means, investigating a historical area of the city of Recife - Carmo Plaza - and exploring testimony from social groups that deal with this issue. The testimonies were obtained through specific questionnaires designed for people with disabilities, for architects and civil servants of cultural heritage. The issues explored professional experiences in order to amplify subtle and sensitive aspects of the proposed discussion. The analysis of urban accessibility of the surrounding Carmo was carried out with resources and procedures available to show multiple difficulties that affect people with disabilities. In addition to photographic records, use of the clinometer and measuring tape, three maps of the location were used (UNIBASE), as well as assessment cards that allow the characterization of the researched environment; information was also collected on urban traffic, access to lots and buildings, urban furniture and transport. These cards were developed by José Antonio Lanchoti in 2005. To investigate the authenticity of historic buildings integrating this area – Ordem Terceira do Carmo Church, Nossa Senhora do Carmo Basilica and the Special Property of Preservation (IEP Nº. 59) – various instruments ascertained its dimensions: artistic, historic, social and scientific. Considered aspects were: shapes and design; substance and materials; use and function; traditions and techniques; location and space; and spirit and feeling, items shown in the letter of Venice in 1964. The authenticity table (Nara-Grid) proposed by Koenraad Van Balen in 2008 is also used. Accessibility and authenticity could then integrate a Matrix, designed by Luís Oscar Ferreira in 2011, and adapted for this study. It was the main result obtained in this study, i.e. an instrument of intervention in order to guide the adaptation of accessibility of the surrounding Carmo without loss of its significance and authenticity values. In addition, the results obtained from the questionnaires suggest the need for courses on accessibility for architects who complained about poor background received at undergraduation, and suggests opportunities for debate on this issue, involving professionals and people with disability, eager for their rights. These people can contribute with necessary information to universal access to cultural values. The conclusion is that it is possible to combine accessibility with the preservation of cultural heritage without damaging the authenticity breaking the simplism to consider the heritage untouchable, not subjected to minimal intervention.

Transformation of the City from the Bottom-Up : Supporting the Cohesion of Sustainability Initiatives

Gilad, Shai, Husson, Margot, Wygle, Mary January 2014 (has links)
The increasing pressures on the global eco-system have reached a critical stage. Cities are the center of most pressures on the biosphere and the contribution to unsustainability. Examined critically, the Sustainable Initiatives addressing urban challenges tend to act independently from each other. This situation is called the Silo-Effect, which is the state of isolation of Sustainability Initiatives in the city arena. The Silo-Effect results in a situation where the Initiatives‘ use of time, energy, and resources is not optimal, therefore creating less effective impact towards urban sustainability. The purpose of this research is to suggest solutions to the Silo-Effect by asking the question, What are the components needed to support the cohesion of Sustainable Initiatives across silos in the city? The methodology of grounded theory inspired the data collection and analysis process of thirteen interviews with professionals from the field. Results confirmed the existence of the Silo-Effect and revealed the main components supporting Cohesion Across Silos. Emerging insights include the need to 1) create Supportive Structures that will maximize the abundant social, human, cultural and economic capitals of practitioners, provide a shared space, and support collaboration, coordination and communications efforts between Initiatives, 2) create new models of local governance and funding systems that support cohesion, and 3) focus experimentation on the neighborhood scale to minimize complexity.

La forme urbaine durable : multifonctionalité et adaptation : redéfinir les espaces urbains en tant que zones partagées multifonctionnelles / Sustainable urban form : multifunctionality and adaptation : redefining urban spaces as multifunctional shared areas

Ghafouri, Atieh 29 June 2016 (has links)
Plus de la moitié de la population mondiale vit dans les villes et cette proportion ne cesse d’augmenter. Afin de rendre nos villes existantes plus durables, de générer de nouvelles formes d’installation et d'apporter des modifications en plus, l'utilisation des installations actuelles devraient être plus efficace ainsi. Un espace urbain, à différentes échelles –un immeuble, un îlot, un quartier ou une ville entière- a une fonction définie, qui est limitée à certaines heures de la journée, les jours du mois ou les mois de l'année. Par exemple, les places de stationnement d'un immeuble possèdent de nombreux espaces libres pendant les heures de travail, tandis que l'aire de stationnement d'un bureau a des zones libres en dehors des heures ouvrables et aussi les jours fériés. Ces espaces pourraient être ravivés avec d'autres fonctions pendant leurs heures de ralenti. D'autre part, les espaces avec des usages privés ou semi-privés pourraient également être attribués à une représentation publique. Par exemple, les cours des écoles peuvent être ouvertes au public pendant les vacances scolaires et temporairement utilisées comme un espace communal partagé. L'objectif de cette thèse est d’étudier les possibilités de faire revivre les espaces publics et semi-publics pour d'autres fonctions que leur fonction principale, pendant leurs heures creuses, afin d’en faire des espaces partagés multifonctionnels. Pour cet objectif, l’identification et la compréhension du fonctionnement de ces espaces, leurs fonctions actuelles et potentielles, et enfin leurs utilisations possibles sont d'une importance primordiale. Il est impératif de déterminer l’ensemble des possibilités d’usage, mais aussi les limites de tels espaces, d’envisager les restrictions juridiques, réglementaires et/ou culturelles, au regard des besoins des utilisateurs potentiels ou des acteurs locaux. Environ 80 cas ont été analysés qui sont spontanément utilisé comme un espace multifonctionnel ou qui ont le potentiel d'être l'un d'entre eux. 30 critères ont été sélectionnés pour l'étude et l'analyse des espaces urbains multifonctionnels. Le résultat final est un ensemble de critères recommandés à prendre en considération pour changer un espace monofonctionnel à l'un multifonctionnel. Ces critères nous conduisaient à l'information qui doit être recueillie dans le but de créer une base de données SIG. Nous concluons par une discussion sur les capacités des SIG pour atteindre les objectifs dans ce domaine et de la façon d'améliorer ses fonctions. / More than half of the world population lives in cities and this proportion is increasing. In order to welcome new populations avoiding urban sprawl, to make our existing cities more sustainable, besides generating new facilities and making changes, the use of current facilities should be more efficient as well. To satisfy these goals, new opportunities have to be found to strengthen the urban sustainability. The multifunctionality of urban spaces might be an efficient concept to (re)design cities and to propose new urban planning rules. The aim of our research is studying the possibilities of reviving public, semi-public and private spaces, for functions other than their main destination and during their idle hours, to consider them as multi-functional shared urban spaces. Different types of relation between function(s) of space and time have been studied. It has been tried to clarify the definition of “multifunctional space” in architecture and urban design based on definitions of the concepts in agriculture and landscape. About 80 cases have been analyzed which are spontaneously used as a multifunctional space or which have the potential to be one. 30 criteria have been selected for studying and analyzing multifunctional urban spaces. The final result is the criteria recommended to take into account while transforming a mono-functional space to a multifunctional one. These criteria would lead us to the information that must be gathered in order to create a GIS data-base customized for this purpose. This research is concluded with a discussion of the capacities of GIS software in the way to improve the operation of an urban space through the multifunctionality.

L'appropriation du modèle de quartiers durables sous climat tropical : mise en place d'une grille d’indicateurs de durabilité urbaine appliquée au quartier de Ravine Blanche sur l'île de La Réunion / The urban sustainability in tropical neighbourhood. Creation an application of an indicators grid. The case of the renovation of Ravine Blanche on Reunion Island

Savidan, Lise 21 March 2013 (has links)
La durabilité urbaine est un sujet de préoccupation contemporain qui a émergé à la fin du 20ème siècle suite à la prise de conscience internationale d'un contexte environnemental et social se dégradant. Les éco-quartiers ou quartiers durables sont une solution proposée pour proposer à une échelle adéquate de nouveaux principes d'aménagements adaptés aux nouveaux enjeux de société.Cette thèse aborde la question de la durabilité urbaine dans les territoires tropicaux, à l'échelle des quartiers. Dans une première partie le débat sur le concept général de durabilité urbaine issu d'Europe du Nord est posé. Il permet de replacer les conditions d'émergence de l'urbanisme durable vis-à-vis de son prédécesseur l'urbanisme moderne. Les principes généraux du concept sont décrits et les sujets qui rassemblent ou séparent la communauté scientifique à ce sujet sont présentés. Dans une seconde partie, le parti de se focaliser sur un éco-quartier adapté au climat local et favorisant le développement de la végétation et d'un mode de vie en extérieur est pris. Des pistes de solutions de conceptions urbaines tropicales sont proposées. Nous créons un outil d'évaluation de durabilité urbaine des éco-quartiers dans ce contexte tropical. Composé de 50 indicateurs séparés en trois axes majeurs considérant les spécificités du terrain tropical, il permet de dresser un portrait global du niveau de durabilité urbaine vis-à-vis de trois niveaux de durabilité : de Base, Performant, Très Performant. Une troisième partie de la thèse, permet d'appliquer cette grille sur le quartier de Ravine Blanche, situé sous un climat tropical humide à La Réunion (Océan Indien), ceci, vis-à-vis des critères de durabilité urbaine. Il s'avère que le quartier passe d'un niveau Non Durable à un niveau de durabilité de Base après rénovation urbaine. Cette thèse permet d'observer l'avancée de la prise en compte du concept de durabilité urbaine dans un territoire tropical humide avec des épisodes de sécheresse. Elle propose aux monteurs de projets souhaitant intégrer le concept de durabilité urbaine, des pistes validées par des principes scientifiques et/ou émanant de praticiens expérimentant depuis plusieurs années les principes de conceptions urbaines et architecturales douces adaptées aux territoires tropicaux. / The urban sustainability is a contemporary preoccupation, because of the international environnemental & social events which take place at the end of the 20th century. Sustainable neighbourhoods are solutions proposed to take in account the new societal stakes into the urban sphere. The intervention scales seems to be adequate to test new conceptions solutions. This phd tried to describe how the concept is adapted into tropical field. In a first part we propose to describe the general concept of sustainability, its emergence conditions, its majors principles and the subjects that gathered or drove apart the scientific community. In a second part we present some specificities of tropical cities, we propose conceptions principles adapted to the climate. We create a tool to evaluate urban sustainability in tropical neigbourhoods. Composed of fifty urban indicators separated into three majors axis, this tool allows to evaluate the durability nivel of urban projects at a quarter scale. We propose three nivel of performance to evaluate durability: Basis, Performant, Very Performant. In a third part of the document, we apply the tool on Ravine Blanche quarter, located into a humide tropical climate, in Reunion island (Indian Ocean). According to the results, thanks to sustainable project of renovation applied on the quarter, Ravine Blanche reaches a Basis level of durability.This phd, allows to evaluate in tropical territories how the concepters take in account the sustainability, comparing to the general concept. It proposes to the urban concepters adapted solutions to deal with the hot climate.

Gröna tak och hållbar urban utveckling : en fallstudie av stadsutvecklingsprojektet Norra Djurgårdsstaden i Stockholm

Andersson, Sara, Sundström, Lovisa January 2020 (has links)
Mänskligheten står inför en framtid med klimatförändringar och utmaningar i form av återkommande värmeböljor, ökad nederbörd, urbanisering samt minskad biologisk mångfald. Det blir allt mer attraktivt att bosätta sig i städer och i kombination med befolkningsökningen sker det en snabb global urbanisering. Detta leder till hög exploateringshastighet i våra städer då andelen hårdgjorda ytor ökar och andelen gröna ytor minskar. Vid byggandet av fastigheter tillkommer en stor mängd outnyttjade ytor, ofta i form av mörka tak. Dessa är inte bara outnyttjade ytor på dyr tomtmark utan skapar ytterligare problem kopplade till urbanisering i form av bland annat minskat albedo. Närhet till grönska gör att människor mår både fysiskt och psykiskt bättre vilket avspeglar sig i en högre betalningsvilja för bostäder i närhet till grönska. Privatpersoner samt fastighetsägare vill gärna profilera sig som hållbara då hållbarhet på senare tid kommit att bli en identitetsskapande “statusmarkör”. Hållbara bostäder kan därmed vara en säljande faktor. Grönska på taken är i sig inget nytt påfund men har senaste åren fått en renässans i Sverige då det visat sig kunna ge fördelar såsom tillgång till grönska för de boende, dagvattenhantering, minskad värmeöeffekt och bättre luftkvalitet. Syftet med studien har varit att undersöka hur ett av Europas mest omfattande stadsutvecklingsprojekt, Norra Djurgårdsstaden i Stockholm, arbetar med hållbar urban utveckling genom gröna tak. De gröna taken kan generera en mängd ekonomiska, ekologiska och sociala fördelar i städer. I studien används urban hållbarhetsteori samt ett egenkonstruerat analysramverk baserat på avsnittet tidigare forskning och teori. Genom en kvalitativ innehållsanalys samt semistrukturerade intervjuer har det framkommit i denna studie att den sociala dimensionen av hållbar stadsutveckling utifrån gröna tak i Norra Djurgårdsstaden överskuggas av de två andra aspekterna; ekonomiskt och ekologiskt. Detta trots att hållbarhetsarbetet med Norra Djurgårdsstaden tagit med alla tre aspekter inom hållbar utveckling; ekonomiskt, ekologiskt och socialt i beaktande när det kommer till planering av stadsdelen. / Humanity is today facing a future with climate change and challenges in the form of periodic heatwaves, increased rainfall and reduced biodiversity. The urbanization processes are driven by expanded population growth and it’s becoming more attractive to live in the cities. This causes the dimension of hard surfaces to increase and consequently the proportion of green spaces sinks. In the construction of housing, a large amount of unused space is added in form of dark areas on roofs. These are not only unused areas on expensive land but create additional problems linked to urbanization in the form of decreased albedo. Furthermore, citizens' willingness to pay has been shown to rise with closeness to green surfaces which can provide recreational and health benefits. Private individuals and property owners would like to profile themselves as sustainable, as the term “sustainability” recently has become an identity-created “status marker”. Sustainable housing can therefore also be a selling factor. Green roofs are not a new invention but have had a renaissance over the years as it has proven to provide the availability to green surfaces for the citizens, stormwater management, heat island effect, and provide healthier air quality. The aim of the study was to examine how the district Norra Djurgårdsstaden in Stockholm, Sweden works with sustainable urban development through green roofs. In this study we have used urban sustainability theory as the green roofs can generate a wealth of economic, ecological and social benefits in urban areas. We have also used our own constructed analysis framework based on previous research and urban sustainability theory. By doing a qualitative content analysis, as well as semi-structured interviews, it has appeared that the social dimension of urban sustainable development in Norra Djurgårdsstaden is overshadowed by the two other aspects; the economic and the ecological. Although the sustainability work in Norra Djurgårdsstaden has taken all three aspects; economic, ecological and social into account when it comes to planning of the district, the social aspect is often neglected.

Green Roofs in Uppsala : Potential food yield and thermal insulating effects of a green roof on a building

Sinha Roy, Sagnik January 2020 (has links)
Climate change has caused severe vulnerabilities for the global food production system and alternative agriculture methods are needed as a solution. Urban agriculture (UA) can be a sustainable solution, making the global food system more resilient and increasing the global food security. Using available empty rooftops to implement green roofs for food production can be a solution to challenges faced by urban agriculture, such as unavailability of land and proper amount of sunlight. The aim of this thesis is to explore the potential of green roofs in Uppsala city, looking into the food production capacity and the energy conservation benefits for buildings having a green roof. With the help of GIS software, 745 flat roofs with a total available area of 877408 m2, were considered feasible for implementing green roofs. Upon calculations based on yields obtained from other studies, the results revealed that the annual vegetable production on potential green roofs in Uppsala city is 23550 T of tomato, 48 T of cabbage and 96 T of chilli. On comparing the tomato production with the amount of tomato consumed annually by the population of Uppsala city, the data reveals that less than 10 % of the estimated production can meet the annual demand.Upon investigating the thermal insulation effects of green sedum roof on a building in Uppsala city, the thesis reveals that annually, 824 kWh or .824 MWh can be saved, providing a monetary benefit of SEK 543. The results point out that, on implementation of green sedum roofs on 100 buildings, about 82 MWh amount of energy can be conserved, thus reducing the overall consumption of fuels such as peat and oil and reducing the emissions of green house gases. Green roofs in comparison with conventional roofs can also act as a heat sink to keep the building cooler during warmer summers, thus reducing the demand for artificial cooling.

Vallastaden; the Up-Side-Down of Urban Planning? : A Qualitative Case Study of Capacity Development on an Urban Scale

Nilsson, Malin January 2023 (has links)
The work towards global sustainable development is growing increasingly complex. Cities and the local urban scale have been acknowledged as important arenas towards sustainability; as they are actors contributing to high climate impacts and contain nebulous circumstances surrounding social orders due to rapid urbanisation. In response to the elaborate difficulties of achieving urban sustainability, Marc Wolfram (2016) conceptualised a framework for urban transformative capacity aimed at analysing and creating capacity for development. By applying relational ontology to a case study of Vallastaden, a newly built neighbourhood in Linköping Sweden this thesis has deepened the understanding of transformative capacity on a local scale. This was accomplished by scrutinising the planning and built environment of Vallastaden in the case study by applying semi-structured interviews, qualitative content analysis and a survey as data collecting methodologies.  The findings of the case study show that Vallastaden has been planned with care by focusing on the human scale and putting emphasis on building meaningful places and aiming to create social sustainability through many shared premises in the neighbourhood. The following six out of ten components of the framework for urban transformative capacity were made visible in the empirical data; (1) transformative leadership, (2) inclusive and multi-form governance, (3) empowered communities of practice, (4) system awareness and memory, (5) reflexivity and social learning and (6) urban sustainability foresight. Furthermore, the most prominent findings display the relations between the agency component (1-3), that the project of Vallastaden contributes to capacity development through social learning and a heterogeneous interdependence of relations between the shared premises and residents.

[en] ACTIVE MOBILITY: CONDITION OF URBAN SUSTAINABILITY IN THE HISTORIC STREETS OF SÃO JOSÉ – RECIFE / [pt] MOBILIDADE ATIVA: CONDICIONANTE DA SUSTENTABILIDADE URBANA NAS VIAS HISTÓRICAS DO BAIRRO DE SÃO JOSÉ – RECIFE

MARIA CYNTHIA DE ARAUJO URBANO 18 May 2023 (has links)
[pt] A mobilidade urbana faz parte de um complexo sistema de infraestrutura, provocando problemas insustentáveis tais como congestionamento, poluição sonora, poluição atmosférica em áreas densamente urbanizadas, como centros urbanos, e resulta em prejuízos no conforto ambiental urbano. Na busca de uma sustentabilidade urbana, ações favoráveis são necessárias à mobilidade urbana e o conceito de mobilidade ativa surge a favor da priorização do deslocamento das pessoas através de meios de transportes não motorizados. Nesse contexto, leva ao objetivo da dissertação, que no atual cenário da mobilidade urbana nas vias do bairro de São José, na cidade do Recife, é identificar medidas para melhorar as condições de acessibilidade e de conforto ambiental urbano para o incentivo da mobilidade ativa. Tais vias pertencem ao Sítio Histórico da cidade, no conjunto de Zonas Especiais de Patrimônio Histórico-Cultural (ZEPH). Através do levantamento de campo, a metodologia aplicada tende a identificar as ameaças e oportunidades para incentivar a mobilidade ativa observando as condições de acessibilidade nos quesitos de rota acessível, as condições de conforto ambiental urbano referentes aos índices de ruídos, emissões de material particulado e conforto térmico, expondo os dados qualitativos e quantitativos obtidos. A pesquisa busca apresentar a mobilidade ativa como uma ação sustentável favorável à redução dos impactos socioeconômicos, ambientais e nas possíveis melhorias da acessibilidade para caminhabilidade nas vias históricas do bairro de São José, priorizando o pedestre e incentivando a mudança de comportamento do seu deslocamento diário, além de usufruir o bairro como ambiente patrimonial e cultural. / [en] Urban mobility is part of a complex infrastructure system, causing unsustainable problems such as congestion, noise pollution, air pollution in densely urbanized areas, such as urban centers, and results in damage to urban environmental comfort. In the search for urban sustainability, favorable actions are necessary for urban mobility and the concept of active mobility emerges in favor of prioritizing the displacement of people through non-motorized means of transport. In this context, it leads to the aim of the dissertation, which in the current scenario of urban mobility on the streets of the São José neighborhood, in the city of Recife, is to identify measures to improve accessibility conditions and urban environmental comfort to encourage active mobility. Such roads belong to the Historic Site of the city, in the set of Special Zones of Historical-Cultural Heritage (ZEPH). Through the field survey, the applied methodology tends to identify the threats and opportunities to encourage active mobility, observing the conditions of accessibility in terms of an accessible route, the conditions of urban environmental comfort related to noise rates, emissions of particulate matter and comfort thermal, exposing the qualitative and quantitative data obtained. The research seeks to present active mobility as a sustainable action that favors the reduction of socioeconomic and environmental impacts and possible improvements in accessibility for walkability in the historic streets of the São José neighborhood, prioritizing pedestrians and encouraging a change in their daily commute behavior, in addition to enjoying the neighborhood as a heritage and cultural environment.
