Dinâmicas do espaço: um contributo para a reflexão

No presente trabalho propôs-se a elaboração de um estudo teórico-prático tendo como intuito principal o questionamento acerca de um conjunto de pressupostos que levam o indivíduo a interpretar e a utilizar o espaço. Isto é, compreender a sua função. Partindo de uma hipótese teórica que coloca em causa tal compreensão como uma condição associada à experiência espacial – perceção e interação – vivida no quotidiano de cada indivíduo, pretendeu-se materializar a seguinte conjetura utilizando como suporte explicativo a conceção de um projeto concetual.

Acessibilidade em área comercial: um estudo do bairro do Alecrim, Natal/RN

Planejar o espaço urbano pensando na inclusão social de pessoas com deficiência significa considerar a acessibilidade como fator essencial para uma mobilidade urbana completa e segura. Esse ideal reflete-se no espaço comercial que, para ser convidativo e livre de barreiras (sejam elas físicas, tecnológicas ou atitudinais), precisa promover o direito de livre acesso a todos os cidadãos. Partindo deste entendimento, esse estudo tem como objetivo geral analisar as condições de acessibilidade da região denominada “Coração do Alecrim”, área de tradicional comércio popular em Natal. A pesquisa recorreu à abordagem multimétodos e aconteceu em três momentos: (i) avaliação técnica da área por meio da aplicação de check-list, elaborado com base na legislação específica e validado por painel de experts; (ii) elaboração de mapas com uso de Sistema de Informação Geográfica (S.I.G.), tendo como base o resultado da análise realizada na primeira etapa; (iii) aplicação de questionários e realização de entrevistas informais com usuários (visitantes, proprietários e comerciários), para coletar dados sobre sua percepção sobre o lugar, complementando a análise técnica efetuada. Resumindo as informações coletadas, foram elaboradas matrizes de descobertas, como uma junção de todas as etapas de análise. Na conclusão são apresentados pontos críticos de acessibilidade (detectados pela pesquisadora ou apontados pelos usuários) e indicadas algumas diretrizes para a intervenção no local, de modo a colaborar para futuros processos de planejamento urbano do bairro do Alecrim.

Espaço de todos ou de ninguém: análise morfológica de transformações espaciais dos Conjuntos Residenciais Parque Serrambi em Natal/ RN

This work analyses the effects of form over the emergence of new patterns of use and occupation in public spaces of housing estates designed in the 1980s and 1990s in Natal’s municipality (Brazil). We start from the premise that form acts on social process (HILLIER; HANSON, 1984), and verify how much the original spatial configuration of Parque Serrambi housing states contributed to the creation of new spatial patterns following the interventions of the people living there. The Serrambi states were built in Natal’s south based on an urbanization model following modernist’s principals and aimed to supply demands for popular dwellings. They were one of the last estates financed by the former National Dwelling Bank (BNH) and supervised by the Dwelling Cooperatives Orientation Institute (INOCOOP), materialized a spatial form different from the highrise dwelling experiences from the same period. The results were obtained through configurational analysis based on Space Syntax conceptual and methodological framework, in which space and society are viewed as interrelated. The analyses was based on represanting and quantifying spatial properties and identificatying social patterns related to the interventions. We identified that the original spatial configurations, associated to subtle changes in the states social patterns, analysed independently of non-morphological categories, gave way to the occupation patterns verrified in both Serrambi cases.

A influência do conforto luminoso na satisfação dos profissionais que atuam no ginásio do Centro de Reabilitação Infantil, Natal-RN

This study addresses the environmental quality in therapeutic spaces for children's rehabilitation. The assumption that space is active and interfere in interpersonal relationships, highlights the importance of natural light to the hospital architecture, to foster the creation of environments that encourage and assist in the recovery of patients in the rehabilitation process. Therefore, interferes with health humanization through positive actions in the physiological and emotional effects of natural light, as facilitators of the health recovery process. In Brazil hospital openings systems projects are built exclusively to follow requirements of the local construction code which do not consider the landscape, but only ventilation and heat stroke; and the luminance levels are treated just as recommendations for artificial lighting. The National Policy for Healthcare Humanization presents the environmental comfort as a priority. However, it does not guidelines for achieving it. In this context this research aims to evaluate the lighting comfort in infant therapeutic areas from the professional satisfaction, in order to identify human preferences on the variables: technical and constructive aspects, relationship with the exterior, internal visual interface and quality elements. With this purpose it was adopted as research strategy the Post-Occupancy Evaluation (Technical Functional) through a multi method approach, which included a case study in the rehabilitation gym of Children Rehabilitation Center, at Natal, Rio Grande do Norte, and a reference study at SARAH Rehabilitation Center, Fortaleza Unit at Ceará, both in Brazil northeast. The results indicate that the definition of openings systems should consider external and internal factors to the building, as the natural landscape, the immediate surroundings and activities to be performed. The POE found out the preference of the professional visual privacy in detriment to other analyzed aspects. Thus, it is expected that this study can contribute to the discussion of luminous quality and generate inputs for future projects or renovations in the Children's Rehabilitation Centers, which should not be projected as hospitals

Integração da simulação termoenergética com o processo de projeto: a análise de 6 casos

This work consists of the integrated design process analyses with thermal energetic simulation during the early design stages, based on six practical cases. It aims to schematize the integration process, identifying the thermal energetic analyses contributions at each design phase and identifying the highest impact parameters on building performance. The simulations were run in the DesignBuilder energy tool, which has the same EnergyPlus engine, validated. This tool was chosen due to the flexible and user friendly graphic interface for modeling and output assessment, including the parametric simulation to compare design alternatives. The six case studies energy tools are three architectural and three retrofit projects, and the author the simulations as a consultant or as a designer. The case studies were selected based on the commitment of the designers in order to achieve performance goals, and their availability to share the process since the early pre-design analyses, allowing schematizing the whole process, and supporting the design decisions with quantifications, including energy targets. The thermoenergetic performance analyses integration is feasible since the early stages, except when only a short time is available to run the simulations. The simulation contributions are more important during the sketch and detail phases. The predesign phase can be assisted by means of reliable bioclimatic guidelines. It was verified that every case study had two dominant design variables on the general performance. These variables differ according the building characteristics and always coincide with the local bioclimatic strategies. The adaptation of alternatives to the design increases as earlier it occurs. The use of simulation is very useful: to prove and convince the architects; to quantify the cost benefits and payback period to the retrofit designer; and to the simulator confirm the desirable result and report the performance to the client

O projeto arquitetônico e a antecipação do projeto de segurança contra incêndio: interferência mútua, interação necessária

The great demand for Federal Institutions of High Education (IFES) design, triggered by the favourable political moment, boosts the public works market and brings with it the stigma of seeking the lowest cost and meet the federal Law 8.666/93 (Bids). In this context, this research makes an analysis of compliance with Fire Safety’s normative requirements in IFES’s architectural designs, taking this point as an evaluation of quality of designs. For the study, were used, IFES’s designs, specifically from UFERSA – Universidade Federal Rural do Semiárido and UFRN – Universidade Federal do Rio Grande do Norte, selected by the relationship use x public served and yet, in the replication of these buildings’ construction. The research was developed through the identification of the Fire Safety applicable legislation to the designs in question, with the determination of the demanded conditions that are architect’s autonomy or that affect the architectural design. Tabulated the requirements, through data collection and measures gathered in the blueprints, was made a comparison and verification of the compliance with these. The results of this evaluation reveal that the minimum requirements was not fulfilled and that IFES’s architectural designs, taken as object in this study, certainly will suffer restrictions in their regularization process with the Fire Department. It is concluded that is necessary an improvement in the IFES’s designs to meet the minimum fire safety regulations and improvement in quality. Moreover, the results direct to the understanding that level of knowledge about Fire Safety received in undergraduate by architects is insufficient for appropriate elaboration of architectural designs in this area.

Simulação de desempenho luminoso para salas de aula em Natal-RN

The city of Natal has a significant daylight availability, although it use isn’t systematically explored in schools architecture. In this context, this research aims to determine procedures for the analysis of the daylight performance in school design in Natal-RN. The method of analysis is divided in Visible Sky Factor (VSF), simulating and analyzing the results. The annual variation of the daylight behavior requires the adoption of dynamic simulation as data procedure. The classrooms were modelled in SketchUp, simulated in Daysim program and the results were assessed by means of spreadsheets in Microsoft Excel. The classrooms dimensions are 7.20mx 7.20m, with windows-to-wall-ratio (WWR) of 20%, 40% and 50%, and with different shading devices, such as standard horizontal overhang, sloped overhang, standard horizontal overhang with side view protection, standard horizontal overhang with a dropped edge, standard horizontal overhang with three horizontal louvers, double standard horizontal overhang, double standard horizontal overhang with three horizontal louvers, plus the use of shelf light in half the models with WWR of 40% and 50%. The data was organized in spreadsheets, with two intervals of UDI: between 300lux and 2000 lux and between 300lux and 3000lux. The simulation was performed with the weather file of 2009 to the city of NatalRN. The graphical outputs are illuminance curves, isolines of UDI among 300lux and 2000 lux and tables with index of occurrences of glare and to an UDI among 300lux 3000lux. The best UDI300-2000lux performance was evidenced to: Phase 1 (models with WWR of 20%), Phase 2 (models with WWR of 40% and 50% with light shelf). The best UDI300-3000lux performance was evidenced to: Phase 1 (models with WWR of 20% and 40% with light shelf) and Phase 2 (models with WWR of 40% and 50% with light shelf). The outputs prove that the daylight quality mainly depends on the shading system efficacy to avoid the glare occurrence, which determines the daylight discomfort. The bioclimatic recommendations of big openings with partial shading (with an opening with direct sunlight) resulted in illuminances level higher than the acceptable upper threshold. The improvement of the shading system percentage (from 73% to 91%) in medium-size of openings (WWR 40% and 50%) reduced or eliminate the glare occurrence without compromising the daylight zone depth (7.20m). The passive zone was determined for classrooms with satisfactory daylight performance, it was calculated the daylight zone depth rule-of-thumb with the ratio between daylight zone depth and the height of the window for different size of openings. The ratio ranged from 1.54 to 2.57 for WWR of 20%, 40% and 50% respectively. There was a reduction or elimination of glare in the passive area with light shelf, or with awning window shading.

Estratégias para obtenção de adequada iluminação natural em escolas: uma análise de sistemas de aberturas para Natal/RN

The purpose of this research is to analyze different daylighting systems in schools in the city of Natal/RN. Although with the abundantly daylight available locally, there are a scarce and diffuse architectural recommendations relating sky conditions, dimensions of daylight systems, shading, fraction of sky visibility, required illuminance, glare, period of occupation and depth of the lit area. This research explores different selected apertures systems to explore the potential of natural light for each system. The method has divided into three phases: The first phase is the modeling which involves the construction of three-dimensional model of a classroom in Sketchup software 2014, which is featured in follow recommendations presented in the literature to obtain a good quality of environmental comfort in school settings. The second phase is the dynamic performance computer simulation of the light through the Daysim software. The input data are the climate file of 2009 the city of Natal / RN, the classroom volumetry in 3ds format with the assignment of optical properties of each surface, the sensor mapping file and the user load file . The results produced in the simulation are organized in a spreadsheet prepared by Carvalho (2014) to determine the occurrence of useful daylight illuminance (UDI) in the range of 300 to 3000lux and build graphics illuminance curves and contours of UDI to identify the uniformity of distribution light, the need of the minimum level of illuminance and the occurrence of glare.

Um percurso sobre o patrimônio e a morfologia urbana do centro de Fortaleza-CE

The incursion into the historical area from Fortaleza´s downtown presents reminiscences of a heritage collection that can be recognized as city built heritage, in architectural and urban aspects. The neighborhood has in its urban tracing a synthesis of the various phases from the Brazilian architecture materialized in its tracing and built goods. This composition mainly covers the eclectic production, passing the time of art déco, including the period of modern production. This paper aims to identify the existing heritage collection. This study aims to identify the existing net assets, the temporality and spatiality that allow to recreate the neighborhood´s form urbain history. Based on the theoretical and methodological support of the urban morphology urban of authors such as Aldo Rossi (1966), Gordon Cullen (1971), José Lamas (1990), Kevin Lynch (1960), and Philippe Panerai (1999) was allowed on a predefined route, to build part of urban memory of Fortaleza. The historical and morphological study runs through a sequenced analysis developed on the articulated subsets, formed by the network neighborhood squares: Praça José de Alencar, Praça Capistrano de Abreu (Lagoinha), Praça Clóvis Beviláquia, Praça do Carmo, Praça Murilo Borges (BNB), Praça Coração de Jesus, Parque das Crianças, Praça do Riacho Pajeú, Praça dos Voluntários (Polícia), Praça do Ferreira, Praça Waldemar Falcão (Correios), Praça General Tibúrcio (Leões), Praça Figueira de Melo, Bosque Dom Delgado (Pajeú), Praça Cristo Redentor, Praça Caio Prado (Sé), Praça dos Mártires (Passeio Público), e Praça Castro Carreira (Estação). Separated the neighborhood based on this square system because it is perceived that there is in these public spaces a path which includes a portion of the urban history of Fortaleza. In addition to this there is a higher concentration of goods in its area in relation to others sectors of the neighborhood, where the loss of the characterization is an imperative of the urban set. In order to find this network of public spaces contained in the study area were proposed two routes based on the city limits of 1875 established by Adolfo Herbster (Fortaleza´s city plan).The path starts by known boulevards (Imperador, Duque de Caxias and Dom Manuel avenues) and the seafront. The study is grounded in the literature review, document and empirical theme, consisting of an overlay of maps, drawings and photographic collection that ratify this net assets as both architectural urban nowadays. Among the results, it was observed that before a current context of loss of locus of the concept of historical-cultural agglomerated, the squares express the strongholds of equity ambience that perhaps stand in urban morphology of the capital from Ceará.

Projeto de mobilidade urbana: estudo sobre processos de integração com habitação de interesse social nas obras do PAC da COPA 2014 em Natal/RN

The public political investments of urban mobility financed by PAC of Cup 2014 have developed discussions and questions by the civil society in Brazil expecting positive results to the urban infrastructure referring to the possible human rights violation and, specially, rights of habitation related to the removing/expropriation noticed. Natal, capital of Rio Grande do Norte, is into this context, due to the urban mobility project linking North Zone of the city to the Arena das Dunas stadium, financed by the PAC of Cup 2014, named West Structural Corridor, that crosses a field of social interest and proposes almost 400 expropriations. This research analyzes how strategies and mechanisms of integration were presented between the mobility project of West Structural Corridor and the Social Interest Habitation affected by this project. We have as hypothesis those projects financed by PAC of Cup 2014/Urban Mobility to Natal/RN present many problems related to the integration of social interest to the housing project, however the National Politics of Urban Development has planned this integration. As a result we detach 3 strategies in the elaboration process about the integration of those politics: (i) integration between municipal secretaries involved in this project; (ii) urban integration of the city; and (iii) integration of public rules or public politics integrated. For each strategy were presented the main mechanisms used to establish the integration of the project. Those mechanisms, however, in this process of establishment/implementation of the empirical research, presented many contradictions and conflicts that compose problems to the integration between the mobility project and the housing area affected.

Representações arquitetônicas na concepção projetual: um estudo com arquitetos e urbanistas do Rio Grande do Norte

The architect materializes his ideas using architectural representations that acts differently during the design process, as instrument that expresses his creatives ideas, as communication between the designer and the client, or as project documentation for its execution (DURAND, 2003). In this paper, it’s been discussed the connexion between the architectural representations and the design process, in a professional context, focusing on representation as an aid to conception. The general aim is to understand the role of architectural representations in the design process by identifying ways of appropriation of their types and resources. The investigation was developed through the theoretical and conceptual studies about the mentioned themes, and the empirical and qualitative research, with architects from the state of Rio Grande do Norte, Brazil, which was developed in two stages: the first one, by filling an electronic form, and the second one, by case studies through execution of design exercises. The results of indirect research showed that the majority of architects and urbanists believes that the way it use the types and representation resources may interfere in design concept. And, after the completion of the case studies, was showed that, motivated by different design conditions, most designers has used the representations differently, which is reflected in different design conceptions.

A releitura de um documento: o processo de tombamento do centro histórico de Natal (RN)

During over seven decades of institutionalizing the national heritage protection legal instrument it can be noticed the many ways of the instrument application, according to the approaches that were assigned to the spaces with heritage values and the dynamic of the elaborated thoughts within this theme. For the application of the instrument effectively, there is a long process that is carried out. This process begins with the study elaboration that aims to subsidize and justify the motivation of property protection, as well as the proposal of buffer zones and national protection areas delimitations, completing the process with the denial of the request or with the publication of the definitive national protection area at the Official Gazette. Starting with the relation between the existing heritage values identification into the historical centres and the definition of its protection areas that the area management will be done, based as well into the management intervention norms established for the protection area perimeter. From this context, the present essay has as porpoise to discuss the approach used for the identification and selection of a historical centre liable for national protection and the repercussion of this identification into the national protection area the was established, using a case study of the national protection of the historical centre of the city of Natal. Starting from the assumption that there are inconsistences and distortions about the text speech of the written document and the spatial delimitation of this document, motivated by an area that privileges the edifications rather than the urban space. Beginning with the urban history methodology, we are based on the precepts of Rossi (2011), Lamas (2010) and Cullen (2009) for that space reading, along with what Sant’Anna (2004) defines as “city-document” to make a new reading of this “heritage value space” verifying if the proposed protection area reflects what is defined as motivation for the national protection area process during the recognizing process. Therefore, it is concluded that it is essential that the buffer zones and the national protection areas are aligned with the text presented at the national protection area instruction, so the norms and criteria definition management process are established. We highlight that a site management and the identified values protection become very difficult without a specific law that beacon the decisions that should be taken.

O processo de elaboração do plano de preservação do conjunto urbanístico de Brasília: uma representação conceitual da política de preservação urbana no DF

This research aims to provide a reflection on the preservation practices of Brasilia as Cultural Heritage in four analytical/political dimensions: conceptual, urban, political-institutional and legal. In order to do that, the preparation process for the Plan for the Preservation of Brasilia Urban Set (PPCUB) was taken as research object. This preservation plan is representative of the context which determines the relation between goals and preservation practices in the social production process of urban space. Designed by Lucio Costa in 1957, Brasilia received the Cultural Heritage title 27 years later, in 1987. It was recognized a World Heritage Site by the United Nations Educational, Scientific and Cultural (UNESCO) in the same year as it "represents a unique artistic piece of work, a masterpiece of creative genius"; and "an outstanding example of a type of construction or architectural compound that illustrates a significant stage in history" (SILVA, 2003). Brasilia’s urban conception, also recognised in the district and federal levels, gives prominence to the 'urban scales' – monumental, residential, gregarious and bucolic – as the main aspects to be preserved. Despite being an undoubted representative, Brasilia seemingly displays a contradiction. On the one hand, the essential value of the city’s urban design is acknowledged as cultural heritage at international, national and district levels. On the other hand, numerous ways of urban interventions disregard the principles of that conception. In 2012, the international Monitoring Report raised some issues which highlight the following main needs: primary need for clear definition of the urban scales’ characteristics and boundaries; definition of a legal framework that conciliates national and district laws of occupation and use of land; creation of inter-sectors executive authority with both decision-making and financial autonomy; and promotion of heritage educational programs. This report also proposes "to cancel the current process of approval conducted by PPCUB and establish a formal consultation process through a committee made up by GDF and IPHAN, which will enable the active participation of University of Brasilia, the Architects Association, ICOMOS and local organizations" (SEDHAB, 2010). Already in its drafting process, the international recommendations evidence that preserving Brasilia’s urban design conception is not among the goals to be achieved. Thus, this research highlights that the intentional nature of PPCUB’s plans does little towards realizing the current proposals.

O registro de procedimentos metodológicos em projetos de intervenção arquitetônica no patrimônio edificado: o caso de Natal-RN

In the midst of growing preservationist awareness, regarding methods of architectural intervention of buildings with a recognized heritage value, there are numerous approaches on how the original heritage value can be protected. However, can these intervention projects be differentiated? Is it possible to identify how they differ (if in fact they do) from an architectural project not related to preservation? Although there are numerous theoretical studies regarding methods utilized in architectonical projects, there appear to be a lack of studies focused on an architectural intervention exclusively focused on areas or edifications that have a recognized heritage value, thereby requiring a reflection on which methodological procedures in an architectonical project serve the purpose of the preservation of the historical aspects. This discussion is of even greater importance because, at the national level, some recent discussions on this type of architectural design seem arbitrary and lack methodological rigor. Therefore, this research attempts to focus equally on the theoretical-methodological practices of preservation as well as the architectural project methods. In an attempt to address these aspects, the focus of this research centers on the case studies of the intervention projects of the maritime passenger terminal of Natal (Terminal Marítimo de Passageriros de Natal), the old government hall (Palacio do Governo - EDTAM) and the old central hotel (Hotel Central) which are situated in the area known as the historic downtown of the city of Natal, within the federal heritage protection polygon. The analyses of these is intended to identify what methodological procedures were recorded in the final product (in the graphical representation of the architectural design and other documents) delivered to IPHAN / RN, the body responsible for review and approval of these architectural projects, noting whether such procedures appear, in some way, in the final product, and if an understanding of the complexity of preservation is evident. The analyses of these projects corroborate the hypothesis that there are unique characteristics, which must be addressed in the intervention project for preservation when compared to new project design. The main characteristic to be addressed is related to the very nature of the project. It is inherent in the dialectical relationship between the need to preserve (the identified heritage values) and the need to modernize (making adaptations to contemporary life). This relationship, denominated in this dissertation as "radical restraint", must, or at least should, guide the actions in the project as well as the technical analyses of the preservationist organization. However, this radical restriction appears more evident in the guidelines put forth by legislators than in the decisions of designers. These legislators require the presentation of documents, aimed at identifying and contextualizing intervention (Ordinance No. 420 of December 22, 2010), that grant (or should grant) assistance in the decision making process. It was evident in the analyses of these documents that there existed a disconnect between the documents produced and the decisions made in the project. This fact can be seen in the total absence of dialogue about theoretical-methodological preservationist principles, which, in our view, is an essential element of the methodological procedures of the intervention project needed to guide the legislative and project design discussions.

Atmosferas arquitetônicas: projeto e percepção na obra de Peter Zumthor

This thesis will discuss the topic architectural atmospheres, based on Peter Zumthor's works and narrative. The subject "architectural atmospheres" is defined in the study as the "complex and general condition, realized by the user during the experience of a place". Atmospheres are composed of the overlap of all physical qualities that compound a space and its perception, conditioned by individual issues of the user. The atmosphere is realized through all human body receivers, in a multi-sensorial process, and affects qualitatively the spacial experience of the places created by architecture. The study has three chapters. The first chapter is a reflection on the issues that architectural atmospheres present. It passes through the concept and definition of the subject and includes a compilation of design principles that act on the architectural atmosphere composition in a variety of projects by a range of professionals. In the second chapter, the procedures adopted by Peter Zumthor in his design process that focus on atmosphere composition are studied. In the third and last chapter, Brother Claus Chapel (Wachendorf, German) and Kolumba Museum (Colon, German) projects, both by Peter Zumthor, are analyzed, in order to comprehend the complex role of elements that constitute the architectural atmosphere of each of these places. The methodology used throughout the thesis consists of bibliography and documental analysis, based on books, plans and material searched on Internet. Furthermore, the project analysis counted with the personal experience of the author of this thesis upon visiting the studied buildings. Finally, in conclusion, it is realized that when architecture is made in order to touch the user, expressed by its built objects, it can be provide a vast conceptual and theoretical basis that valorizes and enriches the experience of its use. It (the architectural atmosphere) is related to an approach that uses the same elements of any other construction, but distinguishes itself by the connections that it implies with humans and its environment. In the face of new patterns unveiled for contemporary architecture, this study contribution is based around the opportunity to understand this particular relationship between user and architectural object, identified as a phenomenological approach of architecture, as well as to update the subject bibliography, still scarce among Brazilian universities.
