O objeto desta pesquisa é a alteração das condições de ventilação natural e de incidência solar provocadas pelo meio urbano. Objetiva-se comprovar a hipótese de que o maior adensamento urbano através da verticalização é compatível com o conforto térmico em edifícios residenciais multifamiliares em altura utilizando apenas a ventilação natural durante 80% das horas do ano. Obstáculos no entorno modificam o comportamento do vento, reduzindo ou incrementando o campo de pressões sobre as fachadas. Por outro lado, edifícios altos situados nas proximidades podem reduzir parcelas significativas da radiação solar sobre planos verticais. O estudo tem como foco o clima quente e úmido de Fortaleza (3° S) e analisa quatro diferentes configurações representativas da morfologia urbana presentes nesta cidade. A investigação vale-se de simulações computacionais em diferentes etapas e escalas de abordagem numa metodologia sequencial e complementar na qual cada fase fornece dados necessários ao estágio seguinte. Partiu-se da avaliação da ventilação urbana através de CFD para as duas direções de vento predominantes, que forneceram dados de Cp sobre as aberturas do edifício adotado. Em seguida, simulou-se o comportamento dos fluxos internos, determinando as taxas de renovação do ar e o campo de velocidades no interior do apartamento. O desempenho térmico anual de três ambientes de permanência prolongada foi calculado e os resultados analisados com base no total de horas dentro da zona de conforto utilizando o modelo adaptativo da ASHRAE (2004). A sensação de resfriamento a partir do movimento do ar foi considerada para a extensão dos limites da zona de conforto. A hipótese mostrou-se válida, uma vez que formas urbanas mais verticalizadas como os cenários 2 e 3 obstruíram parcelas significativas da radiação solar em pavimentos mais baixos comparados a conjuntos urbanos formados por edificações mais baixas. Mesmo diante de vazões de ar cerca de 40% mais baixas em alguns casos com vento sudeste, o cenário 2 apresentou maior quantidade de horas em conforto. O mesmo ocorreu com o cenário 3, cujos valores de vazões de ar com vento leste foram discretamente superiores àqueles obtidos nos cenários 1 e 4, porém alcançando maiores períodos em conforto térmico nos pavimentos mais baixos, reforçando a atuação conjunta da obstrução à radiação solar e a manutenção de condições para ventilar naturalmente as fachadas de edifícios. Ao considerar o efeito de resfriamento provocado pelo movimento do ar, foi possível atingir a condição de conforto térmico em 85% dos casos. Ainda, as baixas correlaçõesentre a vazão de ar e a taxa de ocupação do solo em cada cenário ou a altura média das edificações reforçam a premissa de que a variabilidade do vento e o dinamismo da forma urbana impedem a determinação imediata de quais configurações espaciais reduzirão ou potencializarão as condições de ventilação natural, indicando, também, a possibilidade de compatibilizar maiores níveis de densidade urbana e condições ambientais satisfatórias em edifícios. / The object of this research is the changes in natural ventilation conditions and sunlight caused by the urban environment. The aim is to prove the hypothesis that higher urban density levels thru vertical buildings is compatible with thermal comfort in naturally ventilated residential buildings during 80% of total year´s hours. Surrounding obstacles modify wind patterns, reducing or increasing the pressure field over façades. On the other hand, tall buildings located nearby might reduce significant solar radiation portions over vertical planes. This study focus the hot-humid climate of Fortaleza, Ceará, Brazil (3° S) and analyses four different representative urban forms within this city. The investigation uses computational simulations in different stages and approaching scales in a sequential and complementary methodology in which each phase supplies the necessary data to the next level. Starting point was to evaluate the urban ventilation using a CFD tool according to two dominant wind directions, which provided Cp data over buildings openings. Then, internal flows were simulated in order to determine air changes rates and velocity field in the apartment. Annual thermodynamic performance in threelong permanence rooms was calculated and the results were evaluated using ASHRAE (2004) adaptive model. Cooling effect due to air movement was considered to extend the limits of thermal comfort zone. The hypothesis proved to be valid since more vertical urban forms such as scenarios 2 and 3 obstructed significant solar radiation portions over lower floors compared to urban settlements with lower buildings. Even with airflow rates about 40% lower in some cases with southeast wind, scenario 2 had more hours within the comfort zone. The same occurred with scenario 3, in which airflow rates for east wind were slightly higher than that obtained in scenarios 1 and 4, but achieving greater comfort periods in lower floors, reinforcing the combined effect of obstructing solar radiation and maintaining the conditions to naturally ventilate building´s façades. Considering the cooling effect due to air movement made possible to achieve thermal comfort situations in 85% of the cases. Yet, lower correlations between airflow rates and land use in each scenario or average height of buildings reinforce the premise that wind variability and the dynamism of the urban form prevent the immediate determination of which spatial configuration may reduce or enhance natural ventilation conditions, also indicating that high-density urban levels are compatible with satisfactory environmental conditions within buildings.

Syfte: I takt med urbaniseringen ökar bostadsbristen avsevärt. Som en lösning har förtätning blivit en samhällstrend för att främja ett ekologiskt och socialt hållbart samhälle. Samtidigt som förtätning minskar segregation och ökar tryggheten i bostadsområden, medför det svårigheter och utmaningar vid bostadsprojektering där dagsljus utgör en stor del av det. I samband med detta har forskning visat att dagsljustillgång utgör positiva effekter hos människors fysiska och psykiska hälsa vilket gör detta till en viktig aspekt. Dock konstateras det att en stor del av svenska hushåll inte uppfyller dagsljuskraven. Som följd av bristande kunskap och engagemang hävdas kommuner inte vilja ta sig an problemet. I dagsläget regleras ingen koppling mellan dagsljus och förtätning i detaljplaneringen vilket ökar betydelsen för en tydligare definiering av dagsljuskrav. För en stadstillväxt är det viktigt att uppmärksamma detta problem och öka medvetenheten hos de involverade aktörerna för att möjliggöra täthet bland bostäder utan att dessa äventyrar varandras dagsljustillgång. Syftet med studien är att undersöka hur väl dagsljus och förtätning kan samexistera i täta bostadsområden. Metod: Studien tillämpar en kombination av kvalitativ- och kvantitativt inriktad forskning där frågeställningarna besvaras genom litteraturstudier, intervjuer och fallstudie. Resultat: Förtätning har en avsevärd effekt på dagsljustillgången där bostäder i bottenplan ofta är de mest utsatta. Olika kvartersstrukturer bidrar till varierade dagsljusförhållanden där detta bör planeras i tidigt skede. Värderingar kring dagsljusplanering skiljer sig mellan byggherre, arkitekt och kommun där varje aktörs åsikter präglas av yrkesroll. För att dagsljustillgången inte äventyras i täta kvartersområden bör stor vikt läggas på avskärmningsvinkel och bröstningshöjd där avskärmningsvinkeln får maximalt uppgå till 50°. Konsekvenser: Det är viktigt att samtliga involverade aktörer delar likvärdigt förhållningssätt till dagsljusplanering. Planering av dagsljus är möjligt i detaljplaneringen och bör ske för att undvika senare problematik. Om samexistens av dagsljus och förtätning ska se bör dagsljuskraven sänkas eller bedömas på bostadsnivå. Om detta inte är möjligt, bör en täthetsgräns införas för att täthet kan ske korrekt utan att äventyra dagsljuset. Begränsningar: Resultatet i studien är tillämpbart för studiens specifika fall, dock kan det implementeras i ett kvartersområde med liknande förutsättningar och därmed generaliseras. / Purpose: As urbanization increases, the need for household grows significantly. As a solution, dense urban environment has become a social trend for promoting an ecologically and socially sustainable society and a strategy for the housing shortage. As densification reduces segregation and increases security in residential areas, it entails difficulties and challenges in housing planning. Daylight constitutes a large part of it. Meanwhile, research has shown that daylight access has positive effects on humans’ physical and mental health. However, a large part of Swedish households does not meet the required daylight levels. It is argued that municipalities do not want to address the problem because the lack of knowledge and engagement. At present, the connection between density and daylight is not regulated in the detail planning which increases the importance of a distinct definition of daylight requirements. In order to allow city growth, it is important to address the problem and raise awareness among the involved actors. It is important in order to enable density among homes without these endangering each other's daylight access. The purpose with this study is to investigate how well daylight and densification can coexist in dense residential areas. Method: The study uses a combination of qualitative and quantitative research. Data is collected through literature studies, interviews and a case study. Findings: Densification has a considerable effect on the daylight access, specifically on the ground floor dwellings. Different typologies contribute to varied light conditions and should be planned at an early stage. Approach to daylight planning differ between the developer, architect and municipality where the opinions of each actor are characterized by the position. In order to not jeopardize the daylight access in dense neighborhood areas, great emphasis should be placed on obstruction angle and sill height of the windows with an obstruction angle no more than 50°. Implications: It is important that all the actors involved share an equal approach to daylight planning. Daylight planning is possible in the detailed planning and should be done to avoid later problems. If the coexistence of daylight and densification is to be seen, daylight requirements should be lowered or demanded at the residential level. If this is not possible, a density limit should be introduced so that densification can take place correctly without jeopardizing the daylight. Limitations: The result of the study is applicable to the specific case of the study, however, it can be implemented in a neighborhood area with similar conditions and thus be generalized.

Reinterpreting the issues of urban density development in Hong Kong, this thesis studies the spatial-temporal production processes of Sham Shui Po as a high density social space. Lefebvre’s theory of ‘the production of space’ is applied for a qualitative-based theoretical-empirical analysis. This study criticizes past literature on urban density issues in Hong Kong, dominated by discourses built upon absolute space approach, for their reductionist methodologies and findings simplifying man-space relations and concealing in-depth socio-political implications. The analysis is centred on three dialectically related elements: spatial practices, conceived spaces (objective, abstract knowledge of space), and lived spaces (subjective values on space). Deciphering the geographical-historical interactions of the spatial trialectics over Sham Shui Po in general and at individual level, particularly residential and street-commercial spaces, this thesis suggests that Sham Shui Po is deeply influenced by the spatial abstractions of formal density control comprising planning knowledge, legal establishment, capitalist processes, and informal control on spatial practices. They have together rendered Sham Shui Po a space technically and functionally organized in terms of the development of residential and street spaces, resulting in massive property development, widespread space subdivision for high density dwellings, and unique street life with dynamic and transient concentration of corporeality and materiality. It is also found that recently inhabitants are subject to a dissipation of spatial resistance for alternative dwelling practices due to oppressions from continuously enhanced conceived spaces re-imposing on them and their living spaces. Individuals influenced by consequentially renewed social identities can also be found trapped into high density spaces physically and institutionally, as their spatial practices have been separated, confined and simplified within both interior-residential and exterior-street spaces. Sham Shui Po reveals itself as different spatial mismatches when inhabitants’ lived spaces for securing their spaces of everyday life are without proper response. Deepening the spatial traps and mismatches, the research area is as well undergoing redevelopment processes in reproducing other forms of high density physical fabric, at the expense of original socio-spatialities, through spatial default and historical disconnection

To do this, an investigation is made, starting with the industrial revolution, of historical antecedents which left a mark on 18th, 19th and 20th century cities in the form of designs and plans. / Esta dissertação analisa as propostas de densidades urbanas dos dez projetos premiados no Concurso Bairro Novo, organizado em 2004. Para tanto, são investigados os antecedentes históricos ocorridos a partir da revolução industrial, que marcam, sob a forma de projetos e planos as cidades dos séculos XVIII, XIX e XX.

Sveriges demografiska utveckling visar på att fler och fler flyttar in till storstäderna. Efterfrågan på bostäder leder till ett behov av att förtäta staden i närheten av kommunikationer. Problematiken speglar sig i utmaningen från olika sorters buller. Obebyggda tomter gränsar till trafikerade vägar, stadsmiljö och kollektivtrafik. På grund av detta krävs det att ny bebyggelse regleras genom lagar, riktlinjer, rekommendationer samt tekniska lösningar, utformning och placering för att begränsa skada på människors hälsa och liv. Människor påverkas negativt av buller i form av sjukdomar och psykologiska effekter.Syftet med studien var att få en inblick i fastighetsägarens, kommuner och länsstyrelsens perspektiv på problematiken rörande buller och byggnationer. Detta för att få ökad förståelse om hur buller hindrar stadsförtätning och utveckling i större städer, eller om det finns möjlighet att utveckla staden med hjälp av andra lösningar. Studien använde sig av en kvalitativ forskningsmetod där semistrukturerade intervjuer genomfördes genom fastighetsägare och kommuner.Studien visade att fastighetsägarna anser att buller är en stor del av planeringen och behöver tas hänsyn till genom hela projektet. Det styr även hur de blir begränsade i sitt byggande både inom tekniska åtgärder samt utformning av byggnadsverket. Det mest styrande är dock vilken byggrätt det planeras att bli, där bostäder är den mest begränsade. Motiven för att ändå bygga i en storstad är att marknaden finns där och intäkter kan överkomma kostnaderna. Kommunerna är eniga om att fastigheter där bolag vill bygga oftast är karakteriserade av buller vilket utgör problemet för förtätningen. Det begränsar exploatören i utformning för att minska bullerpåverkan. De menar på att det är viktigt att försäkra sig om en god inomhusmiljö där en god planlösning inte kan ersättas med tekniska lösningar. Även att det är viktigt att läka ihop stadsmiljön för att få en blandad stad. Begränsningarna blir att olika mål kommer i strid, ett där de har en bostadsbrist att förse, bland annat, och ett annat att inte bygga i en bullerexponerad miljö. För framtiden är alla respondenter i studien eniga om att skapa förutsättningar för en hållbar stadsstruktur för att minimera utbredning av staden för att ta del av den infrastruktur som redan existerar är viktigt.Slutsatsen som kunde dras är att en god boendemiljö kräver god planering, samspel och rekommendationer som håller av för människors hälsa och liv i samband med människors behov. Framfarten av befolkningsökningen och behovet av att stadsförtäta kräver i vissa fall avsteg från de riktvärden som existerar idag, även möjligheten att tekniska lösningar i viss mån accepteras. Lagarna är utformade utifrån människors liv och hälsa vilket inte alltid speglar sig i verkligheten. Rekommendationerna samt regler för buller behöver tydliggöras efter den tolkning som görs av Länsstyrelsen rörande riktvärden. Det bör också kunna göras avsteg från riktvärdena efter förutsättningen för platsen. Närheten till stadens aktiviteter samt infrastruktur är den viktiga faktorn i samspel med ofara för hälsa och liv. Fastighetsägare behöver ta i beaktning de tekniska lösningar samt utformningarna på byggnader för att lösa problemet kring bullerfrågan i samspel med kommunens planering samt länsstyrelsens tillsyn. / Sweden's demographic development shows that more and more people are moving into the big cities. The demand for housing leads to a need to densify the city close to communications. The problem is reflected in the challenge of different types of noise. Undeveloped sites are adjacent to busy roads, urban environments and public transport. Because of this, new buildings need to be regulated by laws, guidelines, recommendations and technical solutions, design and location to limit damage to human health and life. People are negatively affected by noise in terms of diseases and psychological effects.The purpose of the study was to gain an insight into the perspectives of property owners, municipalities and county administrative boards on the problem of noise and construction. This in order to gain a better understanding of whether noise hinders urban densification and development in larger cities, or whether there are opportunities to develop the city using other solutions. The study used a qualitative research method where semi-structured interviews were conducted through property owners and municipalities.The study showed that the property owners consider noise to be a major part of the planning process that needs to be taken into account throughout the project. It also governs how they are limited in their construction both in technical measures and the design of the building. However, the most controlling factor is the planned building rights, where housing is the most limited. The motives for building in a large city are that the market is there and revenues can exceed costs. The municipalities agreed that properties where companies want to build are often characterized by noise, which is a problem for densification. This limits the developer in the design to reduce the noise impact. It is important to ensure a good indoor environment where a good floor plan cannot be replaced by technical solutions. It is also important to heal the urban environment in order to achieve a mixed city. The limitations are that different goals come into conflict, one where they have a housing shortage to provide, among other things, and another to not build in a noise-exposed environment. For the future, everyone in the study agreed that creating conditions for a sustainable urban structure to minimize the spread of the city to take advantage of the infrastructure that already exists is important.The conclusion that could be drawn is that a good living environment requires good planning, interaction and recommendations that safeguard human health and life in connection with human needs. The progress of population growth and the need for urban densification requires in some cases deviations from the guideline values that exist today, even the possibility of technical solutions being accepted to some extent. The laws are designed to protect human life and health, which is not always reflected in reality. The recommendations and rules for noise need to be clarified according to the interpretation made by länsstyrelsen regarding target values. It should also be possible to deviate from the guideline values according to the conditions of the location. Proximity to the city's activities and infrastructure is the important factor in the interaction with the danger to health and life. Property owners need to take into account the technical solutions and designs of buildings to solve the problem of noise in interaction with the municipality's planning and länsstyrelsens supervision.

Master of Regional and Community Planning / Department of Landscape Architecture/Regional and Community Planning / Jason Brody / Today, achieving higher residential densities is an integral part of most discussions on concepts such as sustainability, placemaking, smart growth and new urbanism. It is argued that high density environments can potentially improve quality of life through a range of social benefits. In attempting to achieve these benefits, often times, developments that provide more than a certain number of dwelling units are considered desirable and successful high-density developments. However, understanding high residential density merely in terms of an increase in the number of dwelling units over an area of development might not help realize meaningful social benefits; in fact it could result in problems such as parking constraints, increased vehicular traffic, crowding, and eventually abandonment. This implies a dilemma of understanding high density environments holistically. Using literature review and design exploration as two key research methods, this project aims at resolving this dilemma by presenting a holistic understanding of desirable high-density environments. The research works on the idea that high densities are a matter of design and performance. Through synthesis of literature review and explorative design findings, this research focuses on the qualitative aspects of high density environments that make them meaningful and desirable. Through synthesis of literature review and design findings, the research finds that desirable high density environments should (a) Be Physically Compact; (b) Support Urbanity; and (c) Offer Livability and Sense of Place. These three qualitative aspects of high density environments are critical in determining how well such environments perform. The research further proposes eight meaningful goals and seventeen specific guidelines to achieve aforementioned three qualities that influence the performance of high density developments. In addition to these principles and guidelines, opportunities and challenges posed by explorative design exercises also allows identifying certain supplementary guidelines necessary to strengthen the framework. Together, these findings result in a theoretical framework that may be used as an effective design and evaluation tool in considering high density environments. This framework is named “Density Dynamics” to signify various morphological and socio-economic dynamics involved in a holistic understanding of high density environments.

Esta pesquisa teve como ponto de partida o viés do adensamento em áreas urbanas consolidadas - dotadas de infraestrutura, serviços urbanos e ofertas de emprego - servindo de alternativa à expansão periférica, apresentando-se como potencial para a produção habitacional e para o adensamento construtivo. E assim, uma questão se fez pertinente: construir com o coeficiente de aproveitamento (C.A.) máximo permitido pela legislação urbana (Plano Diretor Estratégico do município de São Paulo), numa dada área da cidade, é uma garantia do atendimento da qualidade ambiental de seus edifícios? A pesquisa foi estruturada na busca por responder a esta questão. Seu objeto é a implantação dos edifícios residenciais na cidade de São Paulo, dentro do contexto de C.A. máximo permitido pela legislação. Como objetivo tem-se o estabelecimento de procedimentos para avaliação de desempenho térmico, acústico e luminoso das unidades habitacionais dos edifícios implantados na quadra de estudo, em área central da cidade de São Paulo. O método é essencialmente analítico com base na ferramenta de simulação computacional TAO: uma metodologia para implantação de edificação - ênfase no desempenho térmico, acústico, luminoso e energético (ALUCCI, 2007), para a entrada de dados e modelagem da quadra de estudo.

Como produto da tese tem-se: (I) critérios ambientais que orientarão as escolhas dos arquitetos quanto às distintas alternativas de implantação da edificação no terreno, (II) a flexibilização das decisões de projeto, considerando a realidade local e contemplando, principalmente, as intenções e o partido adotado pelo arquiteto, (III) ao optar por qualquer alternativa de implantação, é possível estimar o desempenho da edificação para todos os critérios de desempenho, (IV) resultados distintos do 1° e do último pavimento tipo, o que aponta a necessidade de projeto de pavimento tipo diferentes, o que ordenará o desenho do edifício, (V) metodologia para avaliação de desempenho térmico, acústico e luminoso do edifício, (VI) proposta de ocupação de quadra e avaliação de desempenho térmico, acústico e luminoso das edificações. / This research took as a starting point the densification of consolidated urban areas - with infrastructure, urban services and jobs - as an alternative to peripheral expansion, posing as potential for housing production and the constructive consolidation. So a question became relevant: Does the use of maximum Floor Area Ratio (FAR) allowed by the urban legislation (Strategic Master Plan of São Paulo) in a given area of the city ensure compliance with environmental quality of its buildings? The research was structured aiming to answer this question. The object of investigation is the implementation of the residential buildings in the city of São Paulo within the maximum FAR allowed by law. The objective has been to establish procedures for assessing thermal, acoustic and luminous performance of housing units in buildings of the study block, in the central area of São Paulo. The method is essentially analytical, based on computational simulation tool TAO: methodology for building\'s site planning to optimize thermal, acoustics, lighting and energy performance (ALUCCI, 2007), for the input of data and modeling study block. The work included collection of primary data through a field survey. As the product of the research we have: (I) environmental criteria to guide the choice of architects among different alternative for site plans, (II) the flexibility of design decisions, considering the local reality and contemplating mainly the approach adopted by the architect, (III) Once the site plan is defined it is possible to estimate the performance of the building for various criteria, (IV) different results of the 1st and last floor type, which points the need for different types of design for the ground floor, (V) methodology for evaluating thermal performance, acoustic and light of buildings, (VI) block site plan proposal and evaluation of its thermal, acoustic and luminous performance.

Neste trabalho foi avaliado o conceito de densidade urbana adotado pelo processo de certificação AQUA (Alta Qualidade Ambiental) Bairros e Loteamentos emitido pela Fundação Vanzolini. Para analisar a aplicação prática dos critérios de desempenho exigidos foi realizado um estudo de caso do primeiro bairro brasileiro certificado pela fundação Vanzolini, o Jardim das Perdizes na cidade de São Paulo. Para análise crítica foram adotados conceitos de sustentabilidade urbana aplicada ao critério de densidade urbana como adensamento de cidade, compactação de edifícios e uso do solo. O estudo foi feito com base no \"Referencial Técnico de Certificação\" - Processo AQUA - (Bairros e Loteamentos/ Set 2011) Versão 0. Trata-se da primeira versão publicada pela Fundação Vanzolini. O referencial foi baseado numa adaptação da certificação original existente na França, o Démarche HQE(TM) Aménagement, da fundação francesa Certivéa. A escolha desse referencial deve-se ao fato do processo de certificação AQUA se propor a adequar-se a realidade brasileira, com base em normas do país e contexto local. A metodologia do trabalho consistiu em analisar os critérios apresentados pelo referencial de certificação servindo como indicador de metas a serem atingidas para obtenção de um planejamento urbano sustentável no que se refere ao tema de densidade urbana. A partir do conhecimento da ferramenta de certificação AQUA Bairros e loteamentos e com base em bibliografia referencial foram analisadas criticamente as metas propostas e sua compatibilidade com o meio urbano em estudo, o estudo de caso Jardim das Perdizes. / This study evaluated the concept of urban density adopted by AQUA (Alta Qualidade Ambiental - High Environmental Quality ) certification process Neighborhoods and Allotments issued by Vanzolini.

As the product of the research we have: (I) environmental criteria to guide the choice of architects among different alternative for site plans, (II) the flexibility of design decisions, considering the local reality and contemplating mainly the approach adopted by the architect, (III) Once the site plan is defined it is possible to estimate the performance of the building for various criteria, (IV) different results of the 1st and last floor type, which points the need for different types of design for the ground floor, (V) methodology for evaluating thermal performance, acoustic and light of buildings, (VI) block site plan proposal and evaluation of its thermal, acoustic and luminous performance.
