A preocupação energética tem impulsionado a humanidade a buscar alternativas sustentáveis de energia. Neste contexto, os edifícios de escritórios têm um papel importante, em especial, devido ao elevado consumo de energia dos sistemas de condicionamento de ar. Para esses sistemas, a possibilidade de utilização de energia solar é uma alternativa tecnicamente possível e interessante de ser considerada, principalmente porque, quando a carga térmica do edifício é mais elevada, a radiação solar também é mais elevada. Dentre os sistemas de condicionamento de ar solar, o sistema térmico - que associa coletores solares térmicos com chiller de absorção - é o mais disseminado, na atualidade. Entretanto, dependendo do caso, outras tecnologias podem ser vantajosas. Uma opção, por exemplo, no caso de edifícios de escritórios, é o sistema elétrico - que associa painéis fotovoltaicos ao chiller convencional de compressão de vapor. Neste trabalho, para um edifício de escritórios de 20 pavimentos e 1000 m2 por pavimento, na cidade de São Paulo, no Brasil, duas alternativas de ar condicionado solar tiveram seus desempenhos energéticos analisados: o sistema térmico - com coletores solares térmicos somente na cobertura e o sistema elétrico - com painéis FV somente nas superfícies opacas das fachadas. Para isso, com o software EnergyPlus do Departamento de Energia dos Estados Unidos obteve-se as carga térmica atuantes no edifício e com a aplicação do método de cálculo de consumo de energia dos sistemas de ar condicionado solar, proposto pelo Projeto SOLAIR da União Européia, adaptado para a realidade da pesquisa, obteve-se o desempenho energético dos sistemas. Os resultados mostraram que, para o edifício de 20 pavimentos, o sistema elétrico tem o melhor desempenho energético, economizando 28% e 71% da energia elétrica que consumiria um sistema de ar condicionado convencional, em um dia de verão e de inverno, respectivamente. O sistema térmico, ao contrário, apresentou um desempenho energético ruim para o edifício estudado, consumindo, por exemplo, em um dia de verão, cerca de 4 vezes mais energia elétrica do que um sistema de ar condicionado convencional. Constatouse que isso ocorreu, pois a área coletora limitada à cobertura foi insuficiente para atender a demanda do chiller de absorção, que passou a operar com frações solares baixas, da ordem de 50% e 20%, de pico, no dia de inverno e de verão, respectivamente. Assim, constatou-se que para que o sistema térmico apresente um desempenho energético satisfatório é preciso que o edifício não seja tão alto. De fato, os resultados mostraram que somente se o edifício tivesse no máximo 2 pavimentos, o sistema térmico teria um desempenho energético melhor do que um sistema convencional. No caso de ser aplicado ao edifício térreo de 1000m2 de área, por exemplo, esse sistema economizaria aproximadamente 65% da energia elétrica do sistema convencional. Por fim, constatou-se também que o desempenho energético do sistema térmico seria elevado com a otimização da área e da tecnologia de coletores solares, com o aprimoramento do sistema de aquecimento auxiliar e com a redução da carga térmica do edifício por meio de técnicas passivas de climatização. / Energy concern has driven human kind to seek sustainable energy alternatives. In this context, office buildings have an important role, especially due to the high energy consumption of air conditioning systems. For these systems, the possibility of using solar energy is technically feasible and interesting to be considered, mainly because generally when the building thermal load is higher, the solar radiation is also higher. Among solar airconditioning systems, the thermal system - which combines solar collectors with absorption chiller - is the most widespread, nowadays. However, depending on the case, other technologies may take advantage. One option, for example, in the case of office buildings, is the electrical system - which combines photovoltaic panels with conventional vapor compression chiller. In this work, an office building of 20 floors with 1,000 m2 floor area, in Sao Paulo, Brazil, two technologies of solar air conditioning had their performance analyzed: the thermal system - presenting solar thermal collectors only on the roof and the electrical system with PV panels only on the opaque surfaces of the facades. For this, the software EnergyPlus of the United States Department of Energy obtained the building thermal load and the with the solar air conditioning energy consumption calculating method proposed by SOLAIR project of the European Union and adapted to this work, energy performance of systems was obtained. The results showed that for this building, the electrical system had the best energy performance, saving 28% and 71% of electricity that would consume a conventional air conditioning system in a summer day and a winter day, respectively. The thermal system, in contrast, showed a poor energy performance, consuming, for example, on a summer day, about four times more electricity than a conventional air conditioning system. It was found that this occurred because the collectors area limited to the roof of the building was insufficient to meet the absorption chiller demand, causing low solar fractions in the operation, of around 50% and 20% peak, in a winter day and in a summer day, respectively. Thus, in order of provide a satisfactory energy performance, the thermal system requires that the building not to be so tall. In fact, the results showed that only if the building had up to two floors, the system would perform better than a conventional system. In case of be installed in a building with the ground floor only, and floor area of 1000m2, for example, this system would save about 65% of the electricity comparing to a conventional system. Finally, it was found that this energy performance would be elevated as well with the optimization of solar collectors area and technology, with auxiliary heating system improvement and with the reduction of thermal load of the building by means of passive air conditioning techniques.

Le comportement humain est modélisé de manière sommaire dans les logiciels de simulation énergétique des bâtiments. Or son impact est considérable et il est à l'origine d'écarts importants entre résultats de simulation et mesures in situ. Les occupants influencent les consommations d'énergie des bâtiments par leur présence et leurs activités, les ouvertures/fermetures de fenêtres, la gestion des dispositifs d'occultation, l'utilisation de l'éclairage artificiel et des appareils électriques, la gestion des consignes de chauffage et les puisages d'eau chaude sanitaire. La thèse propose une modélisation de l'occupation incluant l'ensemble de ces aspects suivant une approche stochastique statistique, pour les bâtiments résidentiels et de bureaux. La construction des modèles fait appel à un grand nombre de données issues de campagnes de mesures, d'enquêtes sociologiques et de la littérature scientifique. Le modèle d'occupation proposé est couplé à l'outil de simulation thermique dynamique Pléiades+COMFIE. En propageant les incertitudes des facteurs du modèle d'occupation et du modèle thermique (enveloppe, climat, systèmes), un intervalle de confiance des résultats de simulation peut être estimé, ouvrant ainsi la voie à un processus de garantie de performance énergétique. / Human behaviour is modelled in a simplistic manner in building energy simulation programs. However, it has a considerable impact and is identified as a major explanatory factor of the discrepancy between simulation results and in situ measurements. Occupants influence buildings energy consumption through their presence and activities, the opening/closing of windows, the actions on blinds, the use of artificial lighting and electrical appliances, the choices of temperature setpoints, and the water consumptions. The thesis proposes a model of occupants' behaviour including all these aspects, according to a stochastic approach, for residential and office buildings. Models' development is based on numerous data from measurements campaigns, sociological surveys and from the scientific literature. The proposed model for occupants' behaviour is coupled to the simulation tool Pléiades+COMFIE. By propagating the uncertainties of factors from the occupants' behaviour model and the thermal model (envelope, climate, systems), the simulation results confidence interval can be estimated, opening the way to an energy performance guarantee process.

Envelopes with low thermal performance are common characteristics in European historic buildings resulting in insufficient thermal comfort and higher energy use compared to modern buildings. There are different types of applications for the European historic buildings such as historic churches, historic museums, historic theatres, etc. In historic buildings refurbished to offices, it is vital to improve thermal comfort for the staff. Improving thermal comfort should not increase, preferably reduce, energy use in the building. The overall aim in this research is to explore how to improve thermal comfort in historic buildings without increasing, preferably reducing, energy use with the application of non-intrusive methods. This is done in form of a case study in Sweden. Thermal comfort issues in the case study building are determined through a field study. The methods include field measurements with thermal comfort equipment, data logging on BMS, and evaluating the occupant’s perception of a summer and a winter period indoor environment using a standardized questionnaire. According to questionnaire and thermal comfort measurements results, it is revealed that the summer period has the most dissatisfied occupants, while winter thermal comfort is satisfactory – but not exceptionally good. Accordingly, natural heat sinks could be used in form of NV, as a non/intrusive method, in order to improve thermal comfort in the building. For the historic building equipped with mechanical ventilation, NV strategy has the potential to both improve thermal comfort and reduce the total electricity use for cooling (i.e. electricity use in the cooling machine + the electricity use in the ventilation unit’s fans). It could decrease the percentage of exceedance hours in offices by up to 33% and reduce the total electricity use for cooling by up to 40%. The optimal (maximum) NV rate (i.e. the potential of NV strategy) is dependent on the thermal mass capacity of the building, the available NV cooling potential (dependent on the ambient air temperature), COP value of the cooling machine, the SFP model of the fans (low SFP value for high NV rate is optimal), and the offices’ door scheme (open or closed doors).

Spatial structures shape human behaviour, or in the words of Bill Hillier – human behaviour does not simply happen in space, it takes on specific spatial forms. How staff interacts in a cellular office differs significantly from the patterns emerging in an open-plan environment. Therefore the dissertation ‘The Space-Organisation Relationship’ analyses how exactly spatial configuration shapes collective behaviours in knowledge-intensive workplace environments. From an extensive literature review it becomes clear that only few insights exist on the relationship between spatial structures and organisational behaviour, despite several decades of intensive research. It is argued that the discourse suffers from disciplinary boundaries; a lack of rigorous research designs; as well as incoherent and outdates studies. Founded on this diagnosis, the dissertation puts up two contrary hypotheses to explain the current state of knowledge: on the one hand it could be argued that hardly any coherent results were found due to the incoherent use of methods and metrics. If this was true it would mean that different organisations would react comparably to similar spatial configurations, if the same methods were used. On the other hand it could be hypothesised that it was inherently impossible to achieve coherent results even with the use of consistent methods, since each space-organisation relationship was unique. To investigate these ideas further, the dissertation employs a combination of qualitative and quantitative methods, embedded within an explorative research design. Both a comparative analysis of different cases and an in-depth study to understand specific organisational behaviours were aimed at by conducting three intensive case studies of knowledge-intensive workplaces: 1) A University, 2) A Research Institute, 3) A Media Company, all of them accommodated in varying spatial structures. Based on a multi-layered analysis of empirical evidence, the dissertation concludes that the relationship between spatial configuration and organisational behaviours can be described by two principles. Firstly, evidence of generic function was found for example between spatial configuration, the placement of attractors, and collective movement flows. These influences are based on general anthropological behaviours and act independently of specific organisational cultures; yet they are rarely found. Secondly, the majority of evidence, especially on more complex organisational constructs such as knowledge flow, organisational cultures and identity suggests that the space-organisation relationship is shaped by the interplay of spatial as well as transpatial solidarities. This means that relationships between people may be formed by either spatial or social proximity. Transpatial relations can overcome distances and are grounded in social solidarities; as such they are not motivated by spatial structures, even though they often mirror spatial order. In essence organisations may react uniquely to comparable spatial configurations. Those two principles – generic function as well as spatial and transpatial solidarities – come in many different forms and jointly shape the character of the space-organisation relationship. This means both hypotheses are true to a degree and apply to different aspects of the space-organisation relationship.:Acknowledgements Table of Contents 1. Introduction – Space and Organisation 2.

Das Interaktionsverhalten von Mitarbeitern in einem Zellenbüro beispielsweise unterscheidet sich grundlegend von den Mustern, die sich in einem Großraumbüro entwickeln. Die vorliegende Dissertation „The Space-Organisation Relationship“ beschäftigt sich daher mit der Frage, wie sich die Verbindung zwischen Raumkonfiguration und kollektivem Verhalten einer Organisation in wissensintensiven Arbeitsprozessen gestaltet. Aus der Literatur wird ersichtlich, dass trotz einiger Jahrzehnte intensiver Forschung nur wenige gesicherte Erkenntnisse existieren zur Frage, wie sich Raumstrukturen auf organisationales Verhalten auswirken. Der Diskurs zeigt deutliche Schwächen durch disziplinäre Grenzen, einen Mangel an wissenschaftlich fundierten Studien, sowie inkohärente und teils veraltete Ergebnisse. Um den aktuellen Kenntnisstand zum Verhältnis von Raum und Organisation zu erklären, stellt die Arbeit zwei entgegengesetzte Hypothesen auf: zum einen wird angenommen, dass der Mangel an vergleichenden Studien sowie methodische Schwächen verantwortlich sind für die uneindeutige Beweislage. Sollte dies der Fall sein, müssten in vergleichenden Studien mit gleichem Methodenansatz übereinstimmende Ergebnisse zu finden sein. Dies würde nahe legen, dass jede Organisation als Kollektiv gleich oder zumindest ähnlich auf vergleichbare Raumstrukturen reagiere. Zum anderen wird die entgegengesetzte Hypothese aufgestellt, dass der Charakter und die inhärente Komplexität des Wissensgebietes exakte Aussagen per se unmöglich mache. Dies könnte verifiziert werden, wenn unterschiedliche Organisationen unterschiedlich auf vergleichbare Raumstrukturen reagieren würden, obwohl dieselben wissenschaftlich fundierten Methoden angewendet wurden. Um dies zu überprüfen benutzt die vorliegende Dissertation eine Kombination aus quantitativen und qualitativen Methoden, eingebettet in einen explorativen Forschungsaufbau, um sowohl vergleichende Analysen zwischen Organisationen durchführen, als auch tiefergehende Interpretationen zu spezifischem organisationalem Verhalten anstellen zu können. Die Arbeit stützt sich auf drei intensive Fallstudien unterschiedlicher wissensintensiver Tätigkeiten – einer Universität, einem Forschungsinstitut, und einem Medienunternehmen, die in jeweils unterschiedlichen räumlichen Strukturen agieren (Zellenbüros, Gruppenbüros, Kombibüros, Großraumbüros). Aufbauend auf der vielschichtigen Analyse empirischer Ergebnisse kommt die Dissertation zur Erkenntnis, dass sich das Verhältnis zwischen Raumkonfiguration und organisationalem Verhalten durch zwei Prinzipien beschreiben lässt. Einerseits sind so genannte generische Einflüsse festzustellen, zum Beispiel zwischen Raumkonfiguration, der Platzierung von Ressourcen und Bewegungsmustern. Diese generischen Einflüsse gehen auf grundlegende menschliche Verhaltensmuster zurück und agieren im Wesentlichen unabhängig von spezifischen Organisationskulturen. Allerdings sind sie selten, und nur wenige Faktoren können als generisch angenommen werden. Andererseits ist die überwiegende Mehrheit der Raum-Organisations-Beziehungen bestimmt vom Wechsel zwischen räumlicher und so genannter trans-räumlicher Solidarität, das heißt Beziehungen zwischen Individuen können sich entweder auf räumliche oder soziale Nähe stützen. Trans-räumliche Beziehungen, die sich aufgrund von sozialer Nähe entfalten können beispielsweise Entfernungen überwinden, und sind daher in erster Linie nicht räumlich motiviert, auch wenn sie sich oft in räumlichen Ordnungen widerspiegeln. Diese beiden Prinzipien – generische Einflüsse sowie räumliche und trans-räumliche Funktionsweisen – treten in vielschichtigen Formen auf und bestimmen den Charakter des Verhältnisses zwischen Raum und Organisation. Damit treffen beide der aufgestellten Hypothesen auf unterschiedliche Aspekte und Teilbereiche des Raum-Organisations-Zusammenhangs zu.:Acknowledgements Table of Contents 1.

Syftet med denna studie var att undersöka klimat- och kostnadseffektiva lösningar för att minska kontorsbyggnaders påverkan på miljön. Byggnader står för en betydande del av Sveriges klimatpåverkan och kostnader, det finns därav behov av att hitta sätt att reducera den påverkan. Teorin som låg till grund för studien var livscykelanalys och livscykelkostnad, som tar hänsyn till klimatpåverkan och kostnader genom hela byggnadens livscykel. Metoden som användes var litteraturstudie, där tidigare forskning och studier analyserades. Diskussion fördes även med sakkunniga personer inom ämnet för att identifiera lösningar för att minska klimatpåverkan och kostnader i byggnader. En hypotetisk fallstudiebyggnad skapades där klimat- och kostnadseffektiva åtgärder implementerades. Genom att titta på byggnadsdelarna stomme, klimatskal, isolering och dess inverkan på energianvändning i en kontorsbyggnad identifierades olika åtgärder som kunde minska klimatpåverkan och kostnader. Dessa inkluderar användning av återvunnet material och minskad energiförbrukning genom förbättrade isoleringsegenskaper. Ytterligare undersöktes val av material och teknik vilket anses hållbara och energieffektiva. Resultatet visar att byggnadsmaterialen har störst påverkan på klimat och kostnaden under Produkt- och Byggproduktionsskedet, medan energiförbrukningen har störst påverkan under skedet Driftenergi i Användningsskedet. De klimatåtgärder som framstår som mest framstående och optimala lösningar för vår fallstudiebyggnad inkluderar användningen av kostnadseffektiva solceller på taket (Åtgärd 7), isolering av ytterväggarna med PIR-isolering (Åtgärd 5), tilläggsisolering av ytterväggarna med EPS-isolering (Åtgärd 3) samt minskat materialspill på byggarbetsplatsen med 25%. Dessa lösningar visar sig inte bara ha en betydligt lägre klimatpåverkan, utan även en mer fördelaktig kostnadseffektivitet över hela livscykeln för fallstudiebyggnaden. / The purpose of this study was to investigate climate and cost-effective solutions to reduce the environmental impact of office buildings. Buildings account for a significant portion of Sweden's climate impact and costs, and there is a need to find ways to reduce this impact. The theoretical framework underlying the report was life cycle analysis and life cycle cost, which consider the climate impact and costs throughout the building's life cycle. The method used was a document study, where previous research and studies were analyzed. A hypothetical case study building was created, where climate- and cost-effective measures were implemented. By examining the building components such as the structure, envelope, insulation, and their impact on energy consumption in an office building, various measures were identified to reduce climate impact and costs. Additionally, the selection of sustainable and energy-efficient materials and technologies was investigated. The results show that building materials have the greatest impact on the environment and cost during the Production and Installation stages, while energy consumption has the greatest impact during the Operational energy use module in the Use stage. The climate measures that stand out as optimal solutions include the use of cost-effective solar panels on the roof (Measure 7), insulating the outer walls with PIR insulation (Measure 5), additional insulation of the outer walls with EPS insulation (Measure 3), and reducing material waste at the construction site by 25%. These solutions not only demonstrate significantly lower climate impact but also exhibit a more advantageous cost-effectiveness over the entire lifecycle.

The project is one building and the floor of the Piazza del Duomo, in Milan, Italy. The piazza is an ideal case history of the development of an urban fabric, and of the consciousness of urbanism itself. / Master of Architecture

I guess my concern is for building. This thesis became a search for form. It did not start that way. The start was a search for reasons, for methods, for a way. It was, however, the pursuit of an understanding of the essence of an object that proved the most rewarding. How l design has come from investigating WHAT I design. The thesis has not left me with answers, but with questions. And what are those questions? The thing: The thing as OBJECT: it seems to boil down to - how is it made? The thing as EVENT: it seems to boil down to - what is it like to be there? The thing as DESIGNED: it seems to boil down to what do I want its nature to be? What will inform my forms? / Master of Architecture

A pesquisa das contribuições dos arquitetos estrangeiros (Jacques Pilon, Franz Heep, Lucjan Korngold e Giancarlo Palanti) nos projetos de edifícios de escritórios na cidade de São Paulo, no período de 1930-1960, partiu de um procedimento metodológico que utilizou dois elementos principais: a revisão da historiografia recente e a identificação das obras através do cruzamento das informações de novas fontes primárias do Acervo de Projetos da Biblioteca da FAUUSP. O primeiro capítulo objetiva a compreensão das contribuições dos edifícios de escritórios na verticalização do centro de São Paulo, através da identificação das obras pioneiras e de seus paralelos com a arquitetura norte americana, das contribuições específicas daqueles arquitetos estrangeiros no contexto das grandes transformações urbanas ocorridas no período e dos desafios técnicos no desenvolvimento do concreto armado. O segundo capítulo apresenta a contribuição dos arquitetos estrangeiros diretamente nos projetos, identificando uma morfologia através da análise da implantação e volumetria, do pavimento térreo e dos acessos, da circulação e das instalações, do pavimento tipo, da estrutura e dos vedos: massa, caixilhos, grelhas, brises e pele de vidro. O terceiro capítulo esboça a prática e as relações profissionais desses arquitetos e de seus colaboradores, estrangeiros ou não, bem como o ensino de projeto dentro dos seus escritórios e o papel do detalhamento na produção e formação desses colaboradores. / ALMEIDA, Moracy Amaral e. Pilon, Heep, Korngold e Palanti: office buildings (1930-1960). Thesis, Faculty of Architecture and Urbanism, University of São Paulo, São Paulo, 2015. ABSTRACT The research on foreign architects (Jacques Pilon, Franz Heep, Lucjan Korngold and Giancarlo Palanti) contributions to the office buildings projects in the city of São Paulo, from 1930 to 1960, came from a methodological procedure. It used two main elements: the review of the recent historiography and the identification of works by crossing the information of new primary sources of FAUUSP Library Archives . The first chapter\'s objective is to understand the contribution of the office buildings to the verticalization center of São Paulo, through the identification of the pioneers architects and their works in comparison to the North American architecture, the specific contributions of those foreign architects during a large urban transformation and the technical challenges in the development process of reinforced concrete. The second chapter presents the contribution of foreign architects directly to the projects, identifying a morphology by analyzing the site plans and volumetry, the ground floor and access paths, circulation and installations, pavement type, structure and envelopment: mass, frames, grilles, louvers and curtain wall. The third chapter outlines the practice and professional relationships of these architects and their collaborators, foreigners or not, as well the design teaching at their offices and the relevance of the detail in the development and training of these team.

Pilon, Heep, Korngold e Palanti: office buildings (1930-1960). Thesis, Faculty of Architecture and Urbanism, University of São Paulo, São Paulo, 2015. ABSTRACT The research on foreign architects (Jacques Pilon, Franz Heep, Lucjan Korngold and Giancarlo Palanti) contributions to the office buildings projects in the city of São Paulo, from 1930 to 1960, came from a methodological procedure. It used two main elements: the review of the recent historiography and the identification of works by crossing the information of new primary sources of FAUUSP Library Archives . The first chapter\'s objective is to understand the contribution of the office buildings to the verticalization center of São Paulo, through the identification of the pioneers architects and their works in comparison to the North American architecture, the specific contributions of those foreign architects during a large urban transformation and the technical challenges in the development process of reinforced concrete. The second chapter presents the contribution of foreign architects directly to the projects, identifying a morphology by analyzing the site plans and volumetry, the ground floor and access paths, circulation and installations, pavement type, structure and envelopment: mass, frames, grilles, louvers and curtain wall. The third chapter outlines the practice and professional relationships of these architects and their collaborators, foreigners or not, as well the design teaching at their offices and the relevance of the detail in the development and training of these team.

O legado das construções clássicas e históricas no Brasil tem sido alvo de demolição, abandono e imperícia. A cidade de Curitiba não foge do contexto, com o intuito de entender a realidade, esta pesquisa tem como objetivo apresentar os principais conceitos e práticas sustentáveis da atualidade, identificando de que maneira e em quais áreas da restauração e conservação da herança cultural podem ser aplicados além de mostrar casos na cidade. Para atender tal objetivo, foram delineados objetivos específicos, como: a sistematização dos conceitos de sustentabilidade e de restauração no contexto atual; analisar diferentes formas de aplicação da tecnologia sustentável na prática de revitalização do patrimônio histórico; entender as principais áreas de interesse nos edifícios a serem preservados; avaliar os elementos arquitetônicos fundamentais para entender a ação sustentável no patrimônio histórico e analisar os parâmetros fundamentais de sustentabilidade em três obras restauradas em Curitiba que são: as Ferragens Hauer, a Vila Sophia e o Hospital Psiquiátrico Nossa Senhora da Luz. Essa pesquisa se justifica, pela necessidade de entender como acontece a relação das políticas, técnicas e ações sustentáveis com a preservação do patrimônio, buscando compreender como isso se reflete no contexto brasileiro. A metodologia utilizada foi exploratória e descritiva. Para analisar as obras de Curitiba utilizou-se a metodologia de Cornejos (2011) que propõe diretrizes para integrar conceitos de sustentabilidade na reutilização adaptativa de edifícios históricos, preservando a dotação cultural da edificação. Os parâmetros analisados envolveram: categoria útil que analisa os aspectos materiais da obra; localização, que analisa os aspectos econômicos; a adaptação vai analisar o aspecto funcional; eficiência energética, que abrange o aspecto tecnológico; senso de lugar, que analisa o aspecto social; padrão de qualidade que se refere ao aspecto legal e o contexto que envolve o aspecto político. Conclui-se que o Brasil precisa de uma aplicação definitiva nas áreas de educação, comunicação, promoção e divulgação do contexto cultural dos seus bens patrimoniais. Para as futuras gerações é importante entender que os conceitos e o desenvolvimento das ideias sustentáveis devem passar obrigatoriamente pela ação direta na restauração do patrimônio cultural. As obras analisadas de Curitiba mostram que a cidade está dando os primeiros passos em direção à preservação e restauro de obras arquitetônicas, revelando a preocupação em deixar uma herança de respeito e valorização a essas construções para as futuras gerações. / The legacy of classical and historical constructions in Brazil has been the target of vandalism, graffiti and total destruction. The city of Curitiba does not escape the rule and, for that reason, the interest for this research appeared, which aims to present the main sustainable concepts and practices of the present, identifying in which way, in what areas of the restoration and conservation of the Cultural heritage, in order to discuss examples in Curitiba. To meet this objective, specific objectives were outlined, such as: the systematization of sustainability and restoration concepts in the current context; Analyze different forms of application of sustainable technology in the practice of revitalizing historical heritage; Understand the main areas of interest in buildings to be preserved; To evaluate the fundamental architectural elements to understand the sustainable action in the historical patrimony and to analyze the fundamental parameters of sustainability in three restored works in Curitiba: Hauer Ferragens, Vila Sophia and Nossa Senhora da Luz Psychiatric Hospital. Justifies, because nowadays, the need to understand how the relation of sustainable policies, techniques and actions with the preservation of the patrimony, seeking to understand how this is reflected in the Brazilian context, becomes clearer day by day. The methodology used was exploratory and descriptive. In order to analyze the works of Curitiba, the methodology of Cornejos (2011) was used to propose guidelines for integrating sustainability concepts into the adaptive reuse of historic buildings, preserving the cultural endowment of the building. The analyzed parameters involved: useful category that analyzes the material aspects of the work; Location, which analyzes the economic aspects; The adaptation will analyze the functional aspect; Energy efficiency, which covers the technological aspect; Sense of place, which analyzes the social aspect; Quality standard that refers to the legal aspect and the context that involves the political aspect. It is concluded that Brazil needs a definitive application in the areas of education, communication, promotion and dissemination of the cultural context of its patrimonial assets. For future generations it is important to understand that the concepts and development of sustainable ideas must pass through direct action in the restoration of cultural heritage. The analyzed works of Curitiba show that the city is taking the first steps towards the preservation and restoration of architectural works, revealing the concern to leave an inheritance of respect to these constructions for future generations.
