Natal qual é a sua cara?: análise do perfil edilício da avenida Eng. Roberto Freire (Natal/RN) à luz da acessibilidade

This study focuses on the building ensemble of Avenida Roberto Freire, a main road in Natal, Brazil, as a material expression of the confluence of various factors among which the following may be emphasized: high level of accessibility due to urban spatial re-structuring and the growth of the real estate market, in view of the increasing number of consumers, who arrived in Natal within the last decades. The intense urban modification process that has been going on in Natal since at least the 1980s, has engendered the formation of long axial lines which express the expansion dynamics and some of the forces subjacent to it. Avenida Roberto Freire has been an iconic example of an urban thoroughfare where architecture becomes primarily a communication support that can be perceived by fast moving passers-by, what brings it close to the venturian concept of strip (Venturi at al, 1972). The building types that line the road not only respond to the dynamics in process but also contribute to intensify it, as they house a variety of uses which attract people and generate more movement. The dynamics is further strengthened by the action of the real estate business which benefits from the increase of highly accessible locations, and from the private and public investments and incentives to tourism that aim to insert this city into the globalized world. Although the intention of reconstituting part of the history of density increase on this avenue in a diachronical perspective was attempted within the limits of the available references and documentation, the central contribution of this study is to understand the relations between topological accessibility and the typological nature of the building ensemble. By observing the synchronic morphological frame resulting from the spatial configuration analysis pertinent to this avenue (cf. Hillier and Hanson,1984) and the inventory and classification of the building ensemble there existing, this study aims to understand how architecture responds to accessibility in view of the real estate pressure, boosted by a cosmopolitanizing process brought about by the continuous flow of foreign and Brazilian arrivals as visitors, temporary or permanent residents

Implicaciones de la accesibilidad configuracional en la movilidad peatonal. El caso de Madrid = The implications of configurational accessibility in pedestrian mobility. The case of Madrid

- Resumen La hipótesis que anima esta tesis doctoral es que algunas de las características del entorno urbano, en particular las que describen la accesibilidad de su red de espacio público, podrían estar relacionadas con la proporción de viajes a pie o reparto modal, que tiene cada zona o barrio de Madrid. Uno de los puntos de partida de dicha hipótesis que el entorno urbano tiene una mayor influencia sobre los viaje a pie que en sobre otros modos de transporte, por ejemplo que en los viajes de bicicleta o en transporte público; y es que parece razonable suponer que estos últimos van a estar más condicionadas por ejemplo por la disponibilidad de vías ciclistas, en el primer caso, o por la existencia de un servicio fiable y de calidad, en el segundo. Otra de las motivaciones del trabajo es que la investigación en este campo de la accesibilidad del espacio público, en concreto la denominada “Space Syntax���, ha probado en repetidas ocasiones la influencia de la red de espacio público en cómo se distribuye la intensidad del tráfico peatonal por la trama urbana, pero no se han encontrado referencias de la influencia de dicho elemento sobre el reparto modal. De acuerdo con la hipótesis y con otros trabajos anteriores se propone una metodología basada en el análisis empírico y cuantitativo. Su objetivo es comprobar si la red de espacio público, independientemente de otras variables como los usos del suelo, incluso de las variables de ajenas entorno no construido, como las socioeconómicas, está o no relacionada estadísticamente con la proporción de peatones viajes en las zonas urbanas. Las técnicas estadísticas se utilizan para comprobar sistemáticamente la asociación de las variables del entorno urbano, denominadas variables independientes, con el porcentaje de viajes a pie, la variable dependiente. En términos generales, la metodología es similar a la usada en otros trabajos en este campo como los de CERVERÓ y KOCKLEMAN (1997), CERVERÓ y DUNCAN (2003), o para los que se utilizan principalmente en la revisión general de TRB (2005) o, más recientemente, en ZEGRAS (2006) o CHATMAN (2009). Otras opciones metodológicas, como los métodos de preferencias declaradas (ver LOUVIERE, HENSHER y SWAIT, 2000) o el análisis basado en agentes (PENN & TURNER, 2004) fueron descartados, debido a una serie de razones, demasiado extensas para ser descritas aquí. El caso de estudio utilizado es la zona metropolitana de Madrid, abarcándola hasta la M-50, es decir en su mayor parte, con un tamaño aproximado de 31x34 Km y una población de 4.132.820 habitantes (aproximadamente el 80% de la población de la región). Las principales fuentes de datos son la Encuesta Domiciliaria de Movilidad de 2004 (EDM04), del Consorcio Regional de Transportes de Madrid que es la última disponible (muestra: > 35.000 familias,> 95.000 personas), y un modelo espacial del área metropolitana, integrando el modelo para calcular los índices de Space Syntax y un Sistema de Información Geográfica (SIG). La unidad de análisis, en este caso las unidades espaciales, son las zonas de transporte (con una población media de 7.063 personas) y los barrios (con una población media de 26.466 personas). Las variables del entorno urbano son claramente el centro del estudio. Un total de 20 índices (de 21) se seleccionan de entre los más relevantes encontrados en la revisión de la producción científica en este campo siendo que, al mismo tiempo, fueran accesibles. Nueve de ellos se utilizan para describir las características de los usos del suelo, mientras que otros once se usan para describir la red de espacios públicos. Estos últimos incluyen las variables de accesibilidad configuracional, que son, como se desprende de su título, el centro del estudio propuesto. La accesibilidad configuracional es un tipo especial de accesibilidad que se basa en la configuración de la trama urbana, según esta fue definida por HILLIER (1996), el autor de referencia dentro de esta línea de investigación de Space Syntax. Además se incluyen otras variables de la red de espacio público más habituales en los estudios de movilidad, y que aquí se denominan características geométricas de los elementos de la red, tales como su longitud, tipo de intersección, conectividad, etc. Por último se incluye además una variable socioeconómica, es decir ajena al entorno urbano, para evaluar la influencia de los factores externos, pues son varios los que pueden tener un impacto en la decisión de caminar (edad, género, nivel de estudios, ingresos, tasa de motorización, etc.). La asociación entre las variables se han establecido usando análisis de correlación (bivariante) y modelos de análisis multivariante. Las primeras se calculan entre por pares entre cada una de las 21 variables independientes y la dependiente, el porcentaje de viajes a pie. En cuanto a los segundos, se han realizado tres tipos de estudios: modelo multivariante general lineal, modelo multivariante general curvilíneo y análisis discriminante. Todos ellos son capaces de generar modelos de asociación entre diversas variables, pudiéndose de esta manera evaluar con bastante precisión en qué medida cada modelo reproduce el comportamiento de la variable dependiente, y además, el peso o influencia de cada variable en el modelo respecto a las otras. Los resultados fundamentales del estudio se expresan en dos modelos finales alternativos, que demuestran tener una significativa asociación con el porcentaje de viajes a pie (R2 = 0,6789, p <0,0001), al explicar las dos terceras partes de su variabilidad. En ellos, y en general en todo el estudio realizado, se da una influencia constante de tres índices en particular, que quedan como los principales. Dos de ellos, de acuerdo con muchos de los estudios previos, corresponden a la densidad y la mezcla de usos del suelo. Pero lo más novedoso de los resultados obtenidos es que el tercero es una medida de la accesibilidad de la red de espacio público, algo de lo que no había referencias hasta ahora. Pero, ¿cuál es la definición precisa y el peso relativo de cada uno en el modelo, es decir, en la variable independiente? El de mayor peso en la mayor parte de los análisis realizados es el índice de densidad total (n º residentes + n º puestos de trabajo + n º alumnos / Ha). Es decir, una densidad no sólo de población, sino que incluye algunas de las actividades más importantes que pueden darse una zona para generar movilidad a pie. El segundo que mayor peso adquiere, llegando a ser el primero en alguno de los análisis estadísticos efecturados, es el índice de accesibuilidad configuracional denominado integración de radio 5. Se trata de una medida de la accesibilidad de la zona, de su centralidad, a la escala de, más un menor, un distrito o comarca. En cuanto al tercero, obtiene una importancia bastante menor que los anteriores, y es que representa la mezcla de usos. En concreto es una medida del equilibrio entre los comercios especializados de venta al por menor y el número de residentes (n º de tiendas especializadas en alimentación, bebidas y tabaco / n º de habitantes). Por lo tanto, estos resultados confirman buena parte de los de estudios anteriores, especialmente los relativas a los usos del suelo, pero al mismo tiempo, apuntan a que la red de espacio público podría tener una influir mayor de la comprobada hasta ahora en la proporción de peatones sobre el resto de modos de transportes. Las razones de por qué esto puede ser así, se discuten ampliamente en las conclusiones. Finalmente se puede precisar que dicha conclusión principal se refiere a viajes de una sola etapa (no multimodales) que se dan en los barrios y zonas del área metropolitana de Madrid. Por supuesto, esta conclusión tiene en la actualidad, una validez limitada, ya que es el resultado de un solo caso — Abstract The research hypothesis for this Ph.D. Thesis is that some characteristics of the built environment, particularly those describing the accessibility of the public space network, could be associated with the proportion of pedestrians in all trips (modal split), found in the different parts of a city. The underlying idea is that walking trips are more sensitive to built environment than those by other transport modes, such as for example those by bicycle or by public transport, which could be more conditioned by, e.g. infrastructure availability or service frequency and quality. On the other hand, it has to be noted that the previously research on this field, in particular within Space Syntax���s where this study can be referred, have tested similar hypothesis using pedestrian volumes as the dependent variable, but never against modal split. According to such hypothesis, research methodology is based primarily on empirical quantitative analysis, and it is meant to be able to assess whether public space network, no matter other built environment and non-built environment variables, could have a relationship with the proportion of pedestrian trips in urban areas. Statistical techniques are used to check the association of independent variables with the percentage of walking in all trips, the dependent one. Broadly speaking this methodology is similar to that of previous studies in the field such as CERVERO&KOCKLEMAN (1997), CERVERO & DUNCAN (2003), or to those used mainly in the general review of T.R.B. (2005) or, more recently in ZEGRAS (2006) or CHATMAN (2009). Other methodological options such as stated choice methods (see LOUVIERE, HENSHER & SWAIT, 2000) or agent based analysis (PENN & TURNER, 2004), were discarded, due to a number of reasons, too long to be described here. The case study is not the entire Madrid’s metropolitan area, but almost (4.132.820 inhabitants, about 80% of region´s population). Main data sources are the Regional Mobility Home Based Survey 2004 (EDM04), which is the last available (sample: >35.000 families, > 95.000 individuals), and a spatial model of the metropolitan area, developed using Space Syntax and G.I.S. techniques. The analysis unit, in this case spatial units, are both transport zones (mean population = 7.063) and neighborhoods (mean population = 26.466). The variables of the built environment are clearly the core of the study. A total of 20 (out of 21) are selected from among those found in the literature while, at the same time, being accessible. Nine out of them are used to describe land use characteristics while another eleven describe the network of public spaces. Latter ones include configurational accessibility or Space Syntax variables. This is a particular sort of accessibility related with the concept of configuration, by HILLIER (1996), one of the main authors of Space Syntax, But it also include more customary variables used in mobility research to describe the urban design or spatial structure (here public space network), which here are called geometric characteristics of the such as its length, type of intersection, conectivity, density, etc. Finally a single socioeconomic variable was included in order to assess the influence non built environment factors that also may have an impact on walking (age, income, motorization rate, etc.). The association among variables is worked out using bi-variate correlation analysis and multivariate-analysis. Correlations are calculated among the 21 independent variables and the dependent one, the percentage of walking trips. Then, three types of multi-variate studies are run: general linear, curvilinear and discriminant multi-variate analysis. The latter are fully capable of generating complex association models among several variables, assessing quite precisely to what extent each model reproduces the behavior of the dependent variable, and also the weight or influence of each variable in the model. This study’s results show a consistent influence of three particular indexes in the two final alternative models of the multi-variate study (best, R2=0,6789, p<0,0000). Not surprisingly, two of them correspond to density and mix of land uses. But perhaps more interesting is that the third one is a measure of the accessibility of the public space network, a variable less important in the literature up to now. Additional precisions about them and their relative weight could also be of some interest. The density index is not only about population but includes most important activities in an area (nº residents + nº jobs+ nº students/Ha). The configurational index (radius 5 integration) is a measure of the accessibility of the area, i.e. centrality, at the scale of, more a less, a district. Regarding the mix of land uses index, this one is a measure of the balance between retail, in fact local basic retail, and the number of residents (nº of convenience shops / nº of residents). Referring to their weights, configurational index (radius 5 integration) gets the higher standardized coefficient of the final equation. However, in the final equations, there are a higher number of indexes coming from the density or land use mix categories than from public space network enter. Therefore, these findings seem to support part of the field’s knowledge, especially those concerning land uses, but at the same time they seem to bring in the idea that the configuration of the urban grid could have an influence in the proportion of walkers (as a part of total trips on any transport mode) that do single journey trips in the neighborhoods of Madrid, Spain. Of course this conclusion has, at present, a limited validity since it’s the result of a single case. The reasons of why this can be so, are discussed in the last part of the thesis.

Jerash: The landscape, urban space, and architecture

The peculiarities of Roman architecture, town planning, and landscape architecture are visible in many of the empire's remaining cities. However, evaluation of the landscapes; and analysis of the urban fabric, spatial compositions, and the concepts and characteristics of its open spaces are missing for Jerash (Gerasa in antiquity) in Jordan. Those missing elements will be discussed in this work, as an example of an urban arrangement that survived through different civilizations in history.^ To address the characteristics of the exterior spaces in Jerash, a study of the major concepts of planning in Classical Antiquity will be conducted, followed by a comparative analysis of the quality of space and architectural composition in Jerash. Through intensive investigation of data available for the area under study, the historical method used in this paper illustrates the uniqueness of the site's urban morphology and architectural disposition.^ An analysis will be performed to compare the design composition of the landscape, urban fabric, and open space of Jerash as a provincial Roman city with its existing excavated remains. Such an analysis will provide new information about the roles these factors and their relationships played in determining the design layout of the city. Information, such as the relationship between void and solid, space shaping, the ground and ceiling, the composition of city elements, the ancient landscapes, and the relationship between the land and architecture, will be acquired.^ A computer simulation for a portion of the city will be developed to enable researchers, students and citizens interested in Jordan's past to visualize more clearly what the city looked like in its prime. Such a simulation could result in the revival of the old city of Jerash and help promote its tourism. ^

Visitabilidade-vivenciabilidade em assentamentos informais : um estudo da acessibilidade de percursos urbanos no Conjunto Santa Terezinha em Fortaleza-CE

This research approaches the issue of accessibility in informal settlements, seeking for the challenges and limits defined by informal urban settings, about the application of accessibility parameters. Take the empirical universe as the Conjunto Santa Terezinha, located in Fortaleza- Ce. Initially, the study presents a reflection about the housing issue in Brazil and the informal settlementes in view of the Right to the City. In this sense, the main references are, the works of Suzanne Pasternak (2008), Nabil Bonduki (1998) and Erminia Maricato (1996-97), among others. Follows with the discussion of the concepts and classifications of this type of settlement, making a content analysis of legislation and regulations relating to accessibility and proposed the discussion of the accessible route as the right strategy for the city. In another step, the methodology of 'walking together' created by Dischinger (2000) was applied in a passage previously chosen, which the researcher follows the disabled person during the journey through city making records like photos and video. The comments and perceptions are compared to the spatial analysis of urban morphology, made from the method of Del Rio (1990) and Panerai (2006), and the parameters of NBR 9050. Knowledge of the area is enriched by the methodology of the production of space made by Henri Lefebvre in his book 'The production of space' (1974) with these categories: space conceived, perceived and lived. Another key reference of this author it s the book 'The Right to the City' (991), which allowed in-depth reflections on the social function of town. In conclusion, the study finds that to guarantee a minimum access conditions in informal sittlements it´s necessary to know the specifics of their morphology, their relations and urban practices in view of the visitability- experiencebility, describing it as complementary concepts

‘This square is our home!’: the organisation of urban space in the spanish 15M movement

Why should a progressive planner/urbanist pay attention to the Spanish 15M movement? From a disciplinary standpoint, its most complex and interesting aspect, which could hypothetically be transferred to other contexts (as in fact happened in the Occupy Wall Street and Occupy London movements), is its 'spatiality'. This article analyses the spatial practices of the so called #spanishrevolution, one of the 2011 social movements that showed the possibility for a new collective appropriation and self-management (autogestion) of urban public space. Although the political goals of the movement were vague at the time of its inception, the practices and spatial imaginaries deployed by it have become consolidated and proven to be yet another of its more successful facets in promoting the spreading and organisation of the protest, making it a phenomenon that calls for reflection on the part of urban thinkers and planners.

Comparison of different space indexing methods for ecological evaluation of urban openspaces

Nowadays we meet many different evaluation methods regarding the ecological performance of green surfaces and parks. All these methods are extremely valuable in determining how well a green surface performs from ecological aspect and to what extent the environment were damaged if these sites would be built or would be developed any other way causing reduction of green surfaces. The goal of the article is to clarify the differences between two evaluation methods (GSI – Green Space Intensity, BARC – Biological Activity Rate Calculation) suitable for urban green infrastructure analysis and to see if any significant difference can be observed evaluating the same site by these methods. Our research sites are in Budapest and their sizes vary between 2,5-8 acres. The most important aspects of site analysis are the following: size and boundaries of the park, existence or lack of water features, the characteristics of their surfaces and the complexity of vegetation. We summarize the data of the site analysis in tables, make a summarizing diagram for visual representation and draw conclusions from the results. As a final step, we evaluate how these two evaluation systems relate to urban open space developments.

O redesenho urbano como gerador de espaços colectivos

Dissertação para obtenção do grau de Mestre em Arquitectura, apresentada na Universidade de Lisboa - Faculdade de Arquitectura.

A configuração urbana do território do Vale do Neiva, Viana do Castelo

A dissertação tem como foco a pesquisa sobre a configuração urbana do estudo de caso, a Unidade Territorial de Vale do Neiva em Viana do Castelo. É um território que contem potencial locativo capaz de promover internamente a fixação industrial, as actividades terciárias e a capacidade em fixar e atrair população. Por outro lado, apresenta dinâmicas e valências económicas em contexto concelhio e regional. A análise configuracional abordada na investigação, através do recurso a técnicas e métodos da Sintaxe Espacial, apura características morfológicas do território permitindo a melhor compreensão do funcionamento e da relação entre forma urbana e relações sociais que a envolvem. Foi abordada a dimensão económica-espacial, nomeadamente, no que diz respeito aos seus componentes e interdependências, visando compreender como se processa a apropriação espacial na malha urbana. A correlação desta abordagem com a metodologia da Sintaxe Espacial possibilitou aumentar conhecimento sobre níveis de acessibilidade das actividade presentes no território. Permitem, adicionalmente, a obtenção de análises mais estruturadas que poderão apoiar decisões tecnicamente mais robustas. Por fim, foi diagnosticado o impacto de algumas acções previstas no Plano Director Municipal de Viana do Castelo, designadamente, as que recaem sobre a rede viária da Unidade Territorial do Vale do Neiva. A análise assentou na simulação e previsão dos efeitos das transformações sobre a configuração urbana. Informa, fundamentadamente, sobre estratégias de planeamento e gestão urbana previstas.

El pulso urbano-industrial de O Porriño

En el planteamiento de la presente disertación, se tienen en consideración las premisas sobre los orígenes de la ciudad, su influencia industrial y su resolución a través de la Teoría de la Lógica Social del Espacio como herramienta de trabajo para los análisis sobre los planes urbanos propuestos para el municipio a estudio, su historia y para la elaboración de propuestas de interacción futuras. Inicialmente, la propuesta surge de la importancia de las vías de comunicación, como elemento creador urbano, es decir, de una determinada infraestructura, la calle-carretera como el “eje” de consolidación de la ciudad, donde se realizan la mayoría de recorridos o flujos en este caso, ejemplificado en la villa de Porriño. El urbanismo pos-moderno, hasta finales de 1970 e inicios de 1980, no abordaba una articulación entre social y técnica, una ciencia de lucha de clases. En este contexto, en 1984, Bill Hillier y Julienne Hanson escriben “La Lógica Social del Espacio” donde argumentan que los movimientos o flujos obedecen a una lógica racional, según la cual, cualquier desplazamiento es llevado a cabo por el menor recorrido y, por tanto, el urbanismo influye en esos flujos. La configuración urbana genera condiciones de accesibilidad y da origen a una diferenciación espacial jerarquizada con conceptos como la conectividad, integración y segregación en un espacio influenciado y construido por la dinámica social. De este modo, la Teoría de la Sintaxis Espacial describe la configuración del trazado urbano y las relaciones entre el espacio público y privado a través de medidas cuantitativas, las cuales permiten entender aspectos importantes del sistema urbano como la accesibilidad y la distribución y usos del suelo consolidado. Por tanto, en la teoría existe una correlación establecida entre las propiedades de los elementos presentados, espacio y sociedad, de modo que cada elemento incumbe al otro y no existiría sin su presencia, siendo fundamental para la definición de la forma. Esta herramienta, Space Syntax, busca la integración del espacio en la ciudad, mediante un análisis y una evaluación a diversas escalas en la red urbana, con una correcta distribución de los espacios, sus usos y las vías de transporte o comunicación necesarios para llegar a los diferentes lugares de la ciudad. La realización de la investigación se centrará en el análisis de la infraestructura viaria en el municipio de Porriño y sus regiones colindantes a lo largo del período histórico analizado, centrándose en tres momentos históricos, 1956, 1986 y la actualidad 2015, debido a los vuelos fotogramétricos de dichas etapas. Así, se obtendrán las respectivas mediciones correspondientes a través del programa informático Depthmap, las cuales se contrarrestarán y compararán entre sí en cada etapa analizada y entre los propios años examinados, para lograr obtener las consideraciones establecidas a lo largo del estudio en cuanto a la influencia comunicativa de los flujos de interacción social en el entorno urbano definido y la respectiva lucha de los sectores industriales y residenciales. En conclusión, se pretende la justificación del origen de la ciudad a través de la comparación sus vías, las cuales fueron fomentadas por el comercio e industria para su creación, dotando así a la industria del dominio del espacio para satisfacer sus necesidades, creando y ampliando su área de intervención, la cual puede ser analizada y tratada no sólo independientemente, sino en el conjunto urbano en el que se sitúa, Porriño.

O pátio jesuítico no Palácio Anchieta: narrativas tipomorfológicas e paisagísticas na cidade de Vitória (ES)

A hipótese defendida nesta pesquisa se baseia na possibilidade de a arquitetura jesuítica implantada em terras brasileiras (século XVI) dialogar e agenciar, num mesmo corpo edificado, e de modo inter-relacionado, aspectos relativos à morfologia urbana, tipologia e paisagem. Lama explica que, como disciplina, a morfologia urbana agrega para si não somente o ambiente construído, mas os meios pelos quais este foi construído em sua interação com a forma urbana, ou seja, os “fenômenos sociais, econômicos e outros motores da urbanização” (LAMAS, 1992). Entender a forma urbana é entender seus elementos constituintes, “quer em ordem à leitura ou análise do espaço, quer em ordem à sua concepção ou produção” (LAMAS, 1992). Estudar a forma urbana significa compreender o lugar onde se insere a cidade e seus elementos constituintes, seus espaços e a inter-relação entre eles e seu contexto, em um espectro abrangente do que se denomina cidade, e urbano. A tipologia arquitetônica e a morfologia urbana estão interligadas no cerne de suas análises, considerando que ambas, segundo Pereira, estudam “duas ordens de fatos homogêneos” (PEREIRA, 2012); estudam elementos constituintes da cidade – arquitetônicos e espaciais – que se sobrepõem ou se complementam de acordo com a escala de análise utilizada. A arquitetura jesuítica do Brasil colonial modela de modo determinante a construção de distintos núcleos urbanos originários na costa brasileira no século XVI. Isso, por meio da implantação de tipologia edilícia que acompanha a doutrina jesuítica de localização e escolha do sítio para suas construções, preconizando segurança, visibilidade do entorno e facilidade de acesso por rios ou pelo mar. Essas construções, realizadas em áreas elevadas, marcaram, por conseguinte, no tempo e no espaço, a paisagem dos primeiros núcleos urbanos brasileiros. A pesquisa analisou um dos exemplares históricos da arquitetura jesuítica no Estado do Espírito Santo, especificamente na cidade de Vitória, capital e núcleo urbano original da colonização portuguesa neste Estado. A instalação dos jesuítas na antiga Vila da Vitória, no séc. XVI, através de sua igreja dedicada a São Tiago e de seu colégio anexo, marca a presença tipológica de uma arquitetura religiosa que influencia a própria morfologia da cidade – caracterizando esta arquitetura como um tipomorfológico - e, por reflexo, participa da construção de sua paisagem urbana secular. Entende-se que o antigo complexo jesuítico de São Tiago e atual Palácio Anchieta, sede governamental e prédio cultural capixaba, é uma arquitetura que permeia estas três grandes narrativas arquitetônicas e urbanas: a tipologia, a morfologia e a paisagem.

A dimensão urbana da arquitetura : ambientes de transição

The present work aims to discuss the urban dimension of architecture and to investigate the role of the architectural spaces in the quality of life in between buildings and their environments. It investigates the transitional spaces between building and thoroughfare; building, thoroughfare and built environments located on the ground level of the buildings, and the potential they have to modify (individually or in groups) the environment where they are. For that, the research studies aspects of the architecture that urban buildings (individually or in groups) have and the inference of the morphology, building type and urban environment quality within the extended context of the Brazilian contemporary city. The analysis of the relation between building, thoroughfare and adjacent surroundings will be performed by the lights of, the evolution they have suffered since European urban spatial interventions that took place in the 19th Century; the morphological rupture on the traditional modern city of the 20th Century; the Brazilian experience focused on edifices, by showing analysis of a group of buildings, in their majority, iconic examples of Brazilian architecture from the 1930s onwards; and finally by an extensive investigation on the micro areas that have been selected in the Camburi region, in the city of Vitória-ES, focused on the characteristics of their architectural complex. As a preliminary conclusion, it can be stated that architecture cannot determine the quality in urban life and in its environments by itself, but because of its architectural and urban configuration of space, it may contribute to quality of environment in its surroundings
