This paper describes a methodology to assess the energy performance of residential buildings starting from the semantic 3D city model of Vienna. Space heating, domestic hot water and electricity demand are taken into account. The paper deals with aspects related to urban data modelling, with particular attention to the energy-related topics, and with issues related to interactive data exploration/visualisation and management from a plugin-free web-browser, e.g. based on Cesium, a WebGL virtual globe and map engine. While providing references to existing previous works, only some general and introductory information is given about the data collection, harmonisation and integration process necessary to create the CityGML-based 3D city model, which serves as the central information hub for the different applications developed and described more in detail in this paper. The work aims, among the rest, at developing urban decision making and operational optimisation software tools to minimise non-renewable energy use in cities. The results obtained so far, as well as some comments about their quality and limitations, are presented, together with the discussion regarding the next steps and some planned improvements.

Freight transport of goods is an indispensable part of everyday life. Without it there would be no delivery of products such as food, water, construction material, technology, furniture, clothes and society, as we know it today, would collapse.  However, there are more and less sustainable ways of transporting goods. Today, the number of freight transport vehicles in cities is increasing steadily which contributes to traffic congestion, unsafety, insecurity, air pollution, noise pollution and climate change. Moreover, as the e-commerce flows are increasing, the importance of sustainable last-mile deliveries increases as well.   The research methods used were literature study and interviews. Firstly, the literature study was realized before two pre-knowledge interviews were conducted. Finally, ten semi structured interviews were conducted with experts, strategists, logisticians,  project managers and consultants.   The data suggests that sustainable urban freight transport can be accomplished with UCCs in combination with cargo bikes to reduce cars in the city. This can be done with the help of four ideas - collaboration, incentives, research and developed bicycle infrastructure.  UCCs are not a new concept but there are few centers that endure due to several factors; flawed business models, lack of expertise or research, subvention dependency and stakeholders’ various engagement and involvement levels. Also, a certain percent of freight that is transported by trucks can be substituted by cargo bicycles but in order to enhance the development of utilizing cargo bicycles as a last-mile delivery option, research and knowledge gap need to be addressed. The conclusion indicates that collaboration between stakeholders, specifically between the private and public sector, is integral. The results also highlight that off-peak deliveries and sustainable last-mile deliveries are feasible solutions. There are knowledge gaps in how UCCs and cargo bikes operate which are potential opportunities for areas of improvement and development. Lastly, policies and regulations set by the local authorities play an integral role to guide the freight industry development towards a more sustainable freight transport. / Godstransport av varor är avgörande i vardagen. Utan fungerande godstransporter skulle det inte finnas leveranser av produkter såsom mat, vatten, byggmaterial, teknik, möbler och kläder, och samhället, som vi är vana vid idag, skulle kollapsa.  Det finns emellertid mer och mindre hållbara sätt att transportera varor på. Idag ökar antalet godstransportfordon i stadskärnor stadigt vilket bidrar till trafikträngsel, osäkerhet, otrygghet, luftföroreningar, buller och klimatförändringar. Dessutom ökar e-handelns flöde i rask fart vilket leder till att betydelsen av hållbara last-mile leveranser ökar likaså. Forskningsmetoderna som användes var en litteraturstudie och intervjuer. Först genomfördes litteraturstudien, följt av två intervjuer för att få en förståelse och en gedigen bakgrund i ämnet. Slutligen genomfördes tio semistrukturerade intervjuer med experter, strateger, logistiker, projektledare och konsulter för att få en fördjupad kunskap om bl.a. problem och utvecklingsmöjligheter inom ämnesområdet.  Resultaten antyder att godstransporter kan utföras med hjälp av samlastningscentraler (UCC) i kombination med lastcyklar för att minska antalet bilar i staden. Effektiva samlastningscentraler ställer krav på väl utvecklat samarbete, incitament, forskning och cykelinfrastruktur. UCC är inget nytt koncept, men det finns få center som överlever på grund av flera faktorer: bristfälliga affärsmodeller, brist på expertis eller forskning, subventionsberoende samt olika nivåer av engagemang och deltagande från intressenter. En viss andel av godstransporterna som utförs med lastbilar kan ersättas av lastcyklar. För att främja utvecklingen av användningen av lastcyklar som last-mile lösning krävs dock forskning och ökad kunskap.  Slutsatsen pekar på att samarbete mellan intressenter, särskilt mellan privata och offentliga sektorer, är avgörande. Resultaten belyser också att off-peak leveranser lågtrafikperioder och hållbara last-mile lösningar är genomförbara alternativ. Det finns kunskapsluckor när det gäller drift av UCC och lastcyklar, vilket kan ses som en möjlighet till förbättring och utveckling. Slutligen spelar lokala myndigheters policys och regler en viktig roll för att styra godstransportindustrins utveckling mot en mer hållbar transport av gods.

Public urban green spaces are crucial parts of cities due to the many connections existing between urban greenery and well-being. Additionally, public urban green space represents a wide range of spatial concepts, such as parks, urban forests, commons, in-between-spaces, and gardens. This study explores challenges for contemporary public urban green space in an increasingly urban world, with high demands on urban growth, and simultaneously the need for more sustainable societies and cities. The aim is to problematize the complex reality for contemporary public urban green space from an urban planning perspective in times of urban densification strategies, global competitiveness between cities and trends of ‘re-naturing’.   The scope of this thesis is based on four high profile case studies. The Green Walkable City in Stockholm and The Green Living Spaces in Birmingham constitute planning strategies with a holistic approach to urban green space, including a strong focus on well-being. The High Line in New York and Parklets in San Francisco represent urban green space concepts, influential both at the local level and in the larger urban planning debate. The results point to a need to acknowledge the complexity inherent to urban green space provision, design, and management. This study contributes with insights of direct connections between narratives of nature, materialized urban greenery projects and conceptualizations of functionality of nature in urban planning projects. From the post-industrial, pristine flirting, crafted wilderness of the High Line; a symbolic but cosmetic scrambling with planters and narratives of parks of parklets; dualistic argumentations of natural values connected to quality over quantity of nature in a densifying and growing Stockholm; to pragmatic yet emotional and ambitious conceptualizations of human nature in biohilic urbanism and green space planning in Birmingham. Gentrification, publicness and production of public space and densification strategies are central themes in urban studies – and public urban green space can play an active role in these processes. / <p>QC 20160518</p>

No. of bitstreams: 1 JoaoStefaniak.pdf: 1510883 bytes, checksum: 309f2fee3412498233d25d9f2b41c7f6 (MD5) Previous issue date: 2011-09-30 / Despite being ensured in the constitutional and infra-constitutional juridical ordainment, the human and fundamental right to housing is far from being fulfilled, since the urban development policy adopted by the Capitalist State is based on its main function that is guaranteeing the production and reproduction of the process of capital accumulation. The urban tools proposed by the City Statute to face property speculation and urban segregation and, consequently induce the reform of the excluding land distribution in Brazilian cities, have not been used by most cities even after ten years of its approval. Housing programs tend to meet the demands of the middle class while the population lower class has no access to banking credit. This scenery reveals contradiction that constitutes the framework of this research: the lack of effectiveness of the right to housing in the city despite its existence in the urban legislation. From the conceptualization of decent housing and the right to housing, this paper highlights the protagonist role of the Capitalist State and the urban social movement regarding housing as a social issue, it also analyses the interlink between housing, the right to housing and the similar categories city and the right to a sustainable city. Taking into consideration the uneven and combined development of the capitalist urbanization process – will focus on the urban phenomenon called slums which constituted the city, necessary object of regularization and land urbanization. The city of Ponta Grossa was chosen for the practical observation of the hypothesis formulated, and its urban municipal legislation as well as the local urban social movement were analyzed. It was concluded that the contradiction between urban norm and urban policy employed by the municipality, which implies the lack of universality of the right to decent housing, is associated to the current phase of capitalist development, characterized by the system structural crisis. This reality is partially hidden by the ideological mirage articulated by the Capitalist State, and a task is posed to the urban social movement: the construction of the social city utopia and a sustainable environment on the ruins of such a mirage. / Apesar de consagrado no ordenamento jurídico constitucional e infra-constitucional o direito humano e fundamental à moradia está longe de ser efetivado, a política de desenvolvimento urbano adotado pelo Estado-capitalista é fundamentada na sua função precípua de garantir a produção e reprodução do processo de acumulação do capital. Os instrumentos urbanísticos estabelecidos para combater a especulação imobiliária e a segregação urbana e, conseqüentemente, induzir a reforma da excludente estrutura fundiária das cidades brasileiras, após dez anos da aprovação do Estatuto da Cidade não foram colocados em prática pela maioria dos Municípios. Os programas habitacionais continuam direcionados a atender as demandas da classe média, pois a camada mais pobre da população não tem acesso ao crédito bancário. Este quadro revela uma contradição que constitui o fio condutor desta pesquisa: a ausência de efetividade do direito à cidade apesar da sua previsão minuciosa na legislação urbanística. Parte-se da conceituação de moradia digna e direito à moradia, destacando o papel protagonista do Estado-capitalista e do movimento social urbano na questão social da habitação, passando pela imbricação de moradia e direito à moradia com as similares categorias cidade e direito à cidade sustentável. Levando em conta o desenvolvimento desigual e combinado do processo de urbanização capitalista - vai enfocar o fenômeno urbano da favela que constituiu a cidade, objeto necessário da regularização e urbanização fundiária. Definida a cidade de Ponta Grossa como lócus para a constatação prática das hipóteses enunciadas, é realizado a análise da legislação urbanística municipal e da atuação do movimento social urbano local. Em sede de síntese conclui-se que a contradição entre a norma urbanística e a política urbana aplicada pelo Município, que implica na ausência de universalização do direito à moradia digna está associada à atual fase de desenvolvimento capitalista, caracterizada pela crise estrutural do sistema. Esta realidade é acobertada pela miragem ideológica articulada pelo Estado-capitalista, sendo que a tarefa posta para o movimento social urbano é a construção da utopia da cidade social e ambientalmente sustentável nos escombros desta miragem.
