Bangkok's dramatic growth in the last three decades has brought with it a wide range of urban problems - economic, architectural, environmental, and social. One problem has been a demand for a new dwelling and work spaces. The Bangkok townhouse has served to meet both needs, but the forms it has taken thus far leaves needs improvement.This creative project proposes improvements to the Bangkok townhouses to make it more responsive to its environment as well as interior functions. The improvements focus on facades, reorganization of interior spaces, and physical townhouse elements. The study uses a typological and environmental study to understand and investigate examples of existing Bangkok townhouses. This includes case study analyses to suggest daylighting design strategies for design applications.This study proposes a facade design guideline and a set of physical arrangement suggestions for enhancing the daylight, ventilation, and accommodation capacity of the Bangkok townhouses. In addition, potential applications of the facade guidelines are illustrated. The facade and physical arrangement guidelines can be a fundamental concept for further development and improvement of the Bangkok and other townhouses in locations throughout Thailand. / Department of Architecture

Since taking hold in the mid 1960s, the modern atrium has become prevalent in many designs and buildings within contemporary architecture. The modern day atrium has endured to find its place amidst our current technologies and design aspirations by continuing to offer a capacity for assisting in urban strategies, providing strong economic returns on investment, conserving or recycling existing buildings, and for its potential to reduce energy consumption. Today, as concerns for energy and the environment rise to prominence within contemporary opinion, the reliance on more integrated conservational design strategies such as what the atrium offers in the matter of material and energy conservation is more relevant than ever. Yet simply including an atrium space within a building does not guarantee its effectiveness in realizing the potential for sustainable design. By selecting to survey a collection of recently completed academic buildings in Southern Ontario, the thesis aimed to examine what current reality exists in our use of the atrium with regards to its conservational characteristics. By examining the atrium’s ability to integrate sustainable design strategies in three areas: the adaptation into existing buildings and flexible program space; the use of effective daylighting; and the provisions to manage passive air handling; the thesis identified what conservational attributes are present and how often these functions are accomplished within the atrium designs of the selected study group of buildings. Overall it was found that the current trends of conservationism in atria of the studied academic buildings are constant, that is, they do not exhibit growth proportional to the increasing awareness of ‘green’ and sustainable thinking seen in today’s culture. Furthermore, the thesis closes with a concluding critique, providing a discussion surrounding the belief that though the atrium is a possible material and energy conservational tool, much of its success can be attributed to the meticulous planning and holistic approach involved in the execution of successfully resolved atria designs.

Successful integration of daylighting systems requires the ability to predict their performance for given climates. In this dissertation, a bottom-up approach is applied to evaluate the optical performance of a selection of daylighting systems. The evaluations are based on the optical properties of the included materials, and part of the dissertation focuses on developing new optical characterization methods. The work on characterization techniques uses an integrating sphere method to characterize the transmittance of light scattering samples more accurately. The method's principle is to reduce the discrepancy in light distribution between the reference and the sample scans by using an entry port beam diffuser. For samples exhibiting distinct light scattering patterns, the benefits of improved uniformity outweigh the errors introduced by the diffusing material. The method is applicable to any integrating sphere instrument, and its simplicity makes it suitable for standard measurements. In addition to normal-hemispherical properties, many daylighting applications require knowledge of the system's spatial light distribution. This dissertation presents a method combining experimental techniques and ray tracing simulations to assess the light distribution from a Venetian blind system. The method indicates that ray tracing based on simplified optical data is inadequate to predict the light distribution for slat materials exhibiting both specular and diffuse properties. Ray tracing is a promising complement to experimental methods used to characterize light guiding or light redirecting systems. Here, spectrophotometric measurements of a scaled mirror light pipe validate a ray tracing model. The model shows excellent agreement with experimental results for both direct and diffuse incident light. The spectral evaluation shows no dramatic color changes for the transmitted light. The ray tracing model is used to evaluate four daylighting systems for a selection of Swedish locations. The percentage of occupied time when the studied systems achieve full design illuminance is relatively low, but the systems provide a valuable contribution to the required illuminance. Additionally, this dissertation provides an overview of available energy efficient windows and illustrates the importance of including the solar energy transmittance when evaluating window energy performance. Overall, this dissertation presents optical characterization techniques for improved performance evaluations of daylighting systems.

The use of natural light is very beneficial in office buildings because energy consumption can be reduced, and working conditions can be enhanced, which positively affect workers' health and productivity. However, bringing natural light into deep plan office buildings is not possible with simple windows or skylights, and light transport systems are necessary to bring natural light into the deep cores of buildings. Light transport systems usually need sun-tracking devices to collect natural light that are complicated, expensive and require continual maintenance. Mirrored light pipes coupled with laser cut panels (LCP) are a passive and simpler daylight transport solution and are the focus of this PhD research. The primary aim has been to improve the technology and achieve the most efficient passive solution possible through the interactive use of theoretical modelling, experimental measurements and case studies. Applications of this technology were investigated in two case studies: 1) as horizontal light pipes for daylight illumination of a high rise building proposal in the tropics; and 2) as vertical light pipes for daylight illumination of a middle-rise deep plan building proposal in a subtropical environment. In both cases, quantitative system performance under best (clear sunny sky) and worst (overcast) case scenarios was undertaken via scale model testing and mathematical modelling. The major conclusion for both case studies was that mirrored light pipe technologies, when coupled with LCP, were effective in introducing sufficient ambient light levels inside buildings and over distances > 20 m from the façade or roof. Average lux levels achieved in the space were 150 to 350 lux for the horizontal light pipes and 50 to 300 lux for vertical light pipes. However, as a passive solution, this technology has two major limitations: 1) the dependence on sun azimuth and elevation angles, which result in variations in illuminance levels during the day and the year; and potentially 2) pipe size, as pipes with a large diameter (e.g. 2 m in diameter for 20 m long pipes) are required for optimal performance, such that the large pipes may limit integration in building design. Two other solutions were assessed to circumvent these limitations to the mirrored light pipe technology: 1) a passive collector that concentrate natural light by using a fluorescent panel to reduce the size of the pipe, and 2) an active collector comprising a LCP rotating 360 degrees in a 24 hour cycle to reduce system dependence on sun azimuth and elevation angles. The low light-to-light efficiency of the fluorescent panels made them inappropriate for collecting sufficient amounts of daylight necessary for daylighting of large buildings. In contrast, the rotating LCP is a very simple active system that by rotating constantly at 15 degrees per hour, reduces the deviation angle between the panel orientation and sun azimuth angle, and significantly increased the system performance. The performance was generally better (e.g. 2.5 times better for light collection under low sun elevation angles) than the passive light pipe system with fixed LCP. However, active systems raise other issues in terms of cost-benefit in constructing, operating and maintaining such systems. Passive mirrored light pipes coupled with LCPs or simple active systems with rotating LCPs have great potential as daylight solutions for deep plan buildings as they can contribute to lowering overall energy consumption, improve workplace health and become an architectural design element. Research is still required on the implementation of the technology into buildings, but the growing trend towards 'green buildings', sustainable design and government regulations or building codes will require more daylighting use in buildings, and will motivate designers to increasingly consider and incorporate such daylighting strategies into future building designs.

This PhD thesis evaluated the applicability of Climate-Based Daylight Modelling (CBDM) as it is presently done. The objectives stated in this thesis aimed at broadly assessing applicability by looking at multiple aspects: (i) the way CBDM is used by expert researchers and practitioners; (ii) how state-of-the-art simulation techniques compare to each other and how they are affected by uncertainty in input factors; (iii) how the simulated results compare with data measured in real occupied spaces. The answers obtained from a web-based questionnaire portrayed a variety of workflows used by different people to perform similar, if not the same, evaluations. At the same time, the inter-model comparison performed to compare the existing simulation techniques revealed significant differences in the way the sky and the sun are recreated by each technique. The results also demonstrated that some of the annual daylight metrics commonly required in building guidelines are sensitive to the choice of simulation tool, as well as other input parameters, such as climate data, orientation and material optical properties. All the analyses were carried out on four case study spaces, remodelled from existing classrooms that were the subject of a concurrent research study that monitored their interior luminous conditions. A large database of High Dynamic Range images was collected for that study, and the luminance data derived from these images could be used in this work to explore a new methodology to calibrate climate-based daylight models. The results collected and presented in this dissertation illustrate how, at the time of writing, there is not a single established common framework to follow when performing CBDM evaluations. Several different techniques coexist but each of them is characterised by a specific domain of applicability.

Daylighting properly employed provides quality to the building. It must be present in every environment, even indirectly, because it complements the psycho-physiological human needs. The light well is a device that can contribute in certain proportions with the interior lighting of a building. Its application requires a careful design as physical principles of light and different for each location under study. This paper aims to contribute to improving the use of daylighting in architectural projects through understanding of parameters and variables that influence the light well s performance in a residential building in the context of Maceió-AL. This evaluation is looking for quantify the reduction of daylighting, as a function of the light well s depth that reaches the bathroom on each floor; the evaluation includes also the distribution of illuminance in a work plan provided for a different size window, a light well s inverted section, as well as, compared to the same environment without a well; analyzing the influence of the reflectance of internal surfaces of the well and the bathroom in the overall average illuminance of the point under study and verify the contribution of the sky and the sun in the most frequent skies in Maceió, in obtaining the illuminance at the same given point for each month of the year and evaluate the influence of azimuth due to seasonality with the purpose of indicate the most appropriate directionrough the deep well. Simulations were performed to indicate the efficiency of the lighting device only for the ninth floor to the existing window size. By increasing the width of the window, we can reach the minimum illuminance values down to the sixth floor, according to the data generated by Troplux 3.12 software. It is also noted the differentiation of the internal illuminance due to the window s orientation and the significant variation of lighting, when studying the contribution of the sky s and sun s light, for the different standardized types of skies and suitable to climate of Maceió. Finally, Finally we can say that the efficiency of the device is only showed on window installed in the top floor with a vertical distance of 1.5 m and 2m horizontal to the point studied. With a window which has an area 2.5 times larger, the light penetrated three floors until the sixth floor to a vertical distance of 10.4 m and 2m horizontal, and that presented higher expectations. The south had the highest illuminance for the option of the existing window, even when a variation of the specular surfaces of the well. Then, the direction north also had good results, then east and finally west. / Fundação de Amparo a Pesquisa do Estado de Alagoas / A iluminação natural corretamente empregada proporciona qualidade à edificação. Deve estar presente em todo ambiente, mesmo que indiretamente, por complementar as necessidades psico-fisiológicas do homem. O poço de luz é um dispositivo de projeto que pode contribuir dentro de certas proporções com a iluminação interna de uma construção. Seu emprego requer um desenho minucioso conforme os princípios físicos da luz e diferente para cada localidade em estudo. O presente trabalho tem como objetivo contribuir para a melhoria do uso da iluminação natural no projeto de arquitetura através da compreensão dos parâmetros e variáveis que influenciam no desempenho de um poço de luz em um edifício residencial no contexto de Maceió-AL. A avaliação busca quantificar a redução da iluminação natural, em função da profundidade do poço de luz, que chega ao banheiro de cada pavimento; avaliar a distribuição das iluminâncias no plano de trabalho proporcionada por um tamanho diferente de janela, uma seção invertida do poço de luz e também comparando ao mesmo ambiente sem o poço; analisar a influência da refletância das superfícies internas do poço e do banheiro na iluminância global média do ponto em estudo; verificar a contribuição do céu e a do sol, nos céus mais freqüentes em Maceió, na obtenção das iluminâncias num mesmo ponto dado para todos os meses do ano e avaliar a influência do azimute em função da sazonalidade com o objetivo de indicar a orientação mais adequada para a obtenção da iluminação através do poço de luz. Foram realizadas simulações que, apontam a eficiência do sistema de iluminação apenas para o nono andar da geometria existente. Ao aumentar a largura da janela, podem-se alcançar mínimos valores de iluminância até o sexto andar, de acordo com processamento no programa Troplux 3.12. Constata-se também a diferenciação da iluminância interna em função da orientação da janela e a variação significativa da contribuição da luz do céu e do sol, para os tipos de céu comuns em Maceió. Enfim, para a janela existente, a eficiência do dispositivo foi apenas para o andar mais alto com uma distância vertical de 1,5m e horizontal de 2m até o ponto estudado. Com a janela grande, de área 2,5 vezes maior, a luz penetrou três pavimentos até o sexto andar a uma distancia vertical de 10,4m e horizontal de 2m, apresentando valores esperadamente mais altos. A orientação sul obteve maiores iluminâncias para a opção da janela existente, até quando se variou a especularidade das superfícies do poço. Em seguida, a orientação norte também apresentou bons resultados, posteriormente a leste e por último a oeste.

Light is one of the most important elements for seizure of the architectural space and can be considered the most valuable resource by the architect, responsible for biological effects, psychological and human visual system. You can also reduce the use of artificial lighting systems, contributing to the growing global awareness of the depletion of natural resources of the planet. However, its use in architecture should be made based on criteria in order to optimize its benefits. Thus, the light shelf can be used as a daylighting control element, which reduces the direct incidence of sunlight, can more evenly distribute light within the room. Using computer simulation software TropLux proceeded to the simulation of a basic room with no light shelf and weather data for the city of Maceio. From there, nine other rooms were created with light shelf and each received a different reflectance configuration of 0.9, 0.7 and 0.5, ranging from diffuse, specular and mixed. the values were compared between the standard room and the other as well as between the points of the same depth between the different rooms in order to establish which setting has allowed a better light performance. As a result, we arrived at the conclusion that the use of light shelf to fully diffuse surface, provided a greater uniformity in the distribution of natural lighting within the environment in comparison to the use of mixed or specular surfaces. The light shelves with reflectance of 0.5 in comparison to others, showed better uniformity of illuminance. / A luz é um dos mais importantes elementos para apreensão do espaço arquitetônico e pode ser considerado o recurso mais valioso pelo arquiteto, sendo responsável por efeitos biológicos, psicológicos e visual do homem. Pode ainda reduzir o uso de sistemas artificiais de iluminação, contribuindo com a crescente conscientização mundial do esgotamento de recursos naturais do planeta. Entretanto, seu uso na arquitetura deve ser feito a partir de critérios, de modo a otimizar seus benefícios. Nesse sentido, a prateleira de luz pode ser usada como um elemento de controle da iluminação natural que permite reduzir a incidência de radiação solar direta, podendo distribuir mais uniformemente a luz dentro do ambiente. Utilizando o software de simulação computacional TropLux, procedeu‐se a simulação de uma sala base sem prateleira de luz e com dados climáticos para a cidade de Maceió. A partir daí, foram criadas outras nove salas com prateleira de luz e cada uma delas recebeu uma configuração diferente com refletância de 0,9, 0,7 e 0,5, variando entre difusa, especular e mista. Foram comparados os valores entre a sala padrão e as demais, bem como entre os pontos de mesma profundidade entre as diferentes salas a fim de estabelecer qual configuração permitiu um melhor desempenho luminoso. Como resultados, chegou‐se à conclusão que a utilização da prateleira de luz com superfície totalmente difusa, proporcionou uma maior uniformidade na distribuição da iluminação natural no interior do ambiente em comparação à utilização de superfícies especulares ou mistas. As prateleiras de luz com refletância de 0,5 em comparação as demais, foram as que melhor distribuíram e uniformizaram a luz natural.

Natural elements as arboreous vegetation can cause considerable obstruction resulting in changes in the amount of daylighting available at indoor environments. On the hand, vegetation can cast shadows and improve the quality of the light passing through the openings, reducing the intensity of the direct sunlight and glare from the sky. However, the vegetation is a difficult element to be incorporated in daylighting design. Regarding computer simulation, for example, all the elements involved in the reproduction of the light should be modeled in three dimensions. Ideally, variables such as height, canopy geometry, quantity, size and spacing of leaves, size of the trunk, branches and twigs, reflectance index, opacity index, among others, should be reproduced in a threedimensional model. However, the modeling is unfeasible, not only because of the complexity of all the variables involved in the process, but also because it overloads the model. Taking these aspects into considerations and based on previous studies on the subject, this research takes the daylighting intercepted by arboreous vegetation as its object of study. Accordingly, the overall goal is to characterize a method for representation and modeling of arboreous vegetation in computer simulation for daylighting. To reach this aim, the hemispherical photography method was used to determine the tree canopies gap fraction. These data helped to develop three different configurations of 3D virtual models of canopies, which were used to simulate the effect of the daylight interception by the tree. Using graphical and statistical methods, we assessed the degree of adjustment of these models with real trees. The results obtained with the MBE and RMSE statistical indicators and considering the variability of light and the scatter levels represented by the median showed that all three models tested in this study may be representative appropriate for real trees. However, it is noteworthy that, possibly, the type of representative model of each tree species is intrinsically linked to the characteristics of each tree. / São diversos os fatores que influenciam a disponibilidade da luz natural, dentre eles destacase a obstrução causada pelo entorno edificado ou natural. Elementos naturais, como a vegetação arbórea, podem provocar uma obstrução considerável, que se traduz na alteração da quantidade de luz natural disponível no interior dos ambientes. Por outro lado, a vegetação pode proporcionar sombras e melhorar a qualidade da luz que incide através das aberturas, reduzindo a intensidade da componente direta do sol, bem como o brilho vindo do céu. Contudo, a vegetação é um elemento de difícil inserção no projeto da iluminação natural. Considerando por exemplo, a prática da simulação computacional, todos os elementos intervenientes na reprodução da luz devem ser modelados tridimensionalmente. Idealmente, variáveis como a altura, a geometria da copa, a quantidade, dimensão e espaçamento das folhas, dimensão do tronco, ramos e galhos, índice de refletância, índice de opacidade, entre outras, devem ser reproduzidos no modelo tridimensional. Entretanto, essa modelagem é impraticável, não somente devido à complexidade de todas as variáveis envolvidas no processo, como também, na sobrecarga do modelo. A partir destas considerações e com base em estudos anteriores sobre o tema, esta pesquisa toma como objeto de estudo a iluminação natural interceptada pela vegetação arbórea. Neste sentido, o objetivo geral é caracterizar um método para a representação e modelagem da vegetação arbórea na simulação computacional da luz natural. Para tanto, através do método de fotografia hemisférica, foi possível obter dados de fração de lacuna de copas arbóreas. Estes dados ajudaram a desenvolver três diferentes configurações de modelos tridimensionais virtuais de copas, os quais foram usados para simular o efeito da intercepção da árvore na luz do dia. Por meio de métodos gráficos e estatísticos, avaliou-se o grau de ajuste desses modelos com as árvores reais. Os resultados obtidos com os indicadores estatísticos MBE e RMSE e considerando ainda a variabilidade da luz e os níveis de dispersão, representado pela mediana, demonstraram que todos os três modelos testados nesta pesquisa podem ser representantes adequados das árvores reais. Contudo, ressalta-se que, possivelmente, o tipo de modelo representante de cada espécie arbórea esteja intrinsicamente ligado às características próprias de cada árvore.

Under this view, the scope of this paper discusses the influence of variables around and of the building on the illuminance and glare of its indoor environments. From a case study in Manaíra, a district in the city of João Pessoa PB, the aspects which were evaluated as independent variables were: the degree of obstruction of the surroundings, the properties of the external vertical surfaces - reflectance and solar protection elements, the height of the floor and orientation. The dependent variables related to daylighting in indoor environments were: the illuminance distribution, the percentage of the illuminated area inserted into the useful range of illuminance and the occurrence of glare. Through computer simulation, by using the Daysim software, the use of dynamic metric allowed the extraction of data of the Useful Daylight Illuminance (UDI 300-3000lux), besides values in temporal and spatial scale in the period of a year corresponding to the weather file of the city mentioned. In addition, the ratios of Daylight Glare Probability (DGP) were found through the Evalglare program. It was possible, by the use of graphic and statistical methods, to find differences between the 120 models of indoor environments inserted in three different urban settings and to compare the research variables which showed the strongest influence. It was noticed that the sun protection devices in facades contributed most significantly to the useful frequency range of illuminance compared to scenarios without shading, being it paramount to the increase of lighting levels and the reduction of visual discomfort. Additionally, it was noticed that the most clogged pavements, like the ground, were the most uniform. However, there was a level of illuminance below the range of sufficiency (UDI <3000lux). Regarding the variables of the building, the facades which are oriented Northwest and Northeast have better performance, featuring environments with minor variations of illuminance, satisfactory percentage of illuminated area above 75% of UDI, as well as larger bands of unnoticeable glare. Differently, the Southwest facade recorded the worst results in respect of lighting levels and the Southeast facade is the most prone to the increase of glare probability, especially in embedded environments of scenarios with maximum reflection of the facades and in situations without interference from the surroundings and with the contribution of direct light. / Com o adensamento dos centros urbanos e a verticalização, a malha urbana vem sendo modificada a ponto de afetar significativamente a disponibilidade da luz natural nas edificações. Sob esta ótica, o escopo do presente trabalho aborda a influência das variáveis de entorno e do edifício sobre as iluminâncias e ofuscamento nos ambientes internos. A partir de um estudo de caso no Bairro de Manaíra na cidade de João Pessoa-PB, foram avaliadas como variáveis independentes: o grau de obstrução do entorno, as propriedades das superfícies verticais externas refletância e elementos de proteção solar, a altura do pavimento e a orientação. As variáveis dependentes, relacionadas com a iluminação natural nos ambientes internos, foram: a distribuição das iluminâncias, o percentual de área iluminada inseridas na faixa útil de iluminâncias e a ocorrência de ofuscamento. Por meio de simulação computacional, utilizando o software Daysim, o uso da métrica dinâmica permitiu extrair dados de iluminâncias natural útil (INU 300-3000lux), além de valores em escala temporal e espacial no período de um ano correspondente ao arquivo climático da cidade já mencionada. Em complemento, foram encontrados os índices da probabilidade de ofuscamento da luz natural (POLN) através do aplicativo Evalglare. Com métodos gráfico e estatístico, foi possível verificar diferenças entre os 120 modelos de ambientes internos inserido em três cenários urbanos distintos e comparar as variáveis de pesquisa que apresentaram maior influência. Percebeu-se que os dispositivos de proteção solar nas fachadas contribuíram mais significativamente para frequência das iluminâncias na faixa útil quando comparadas com os cenários sem sombreamento, sendo primordial para aumento dos níveis de iluminação e redução dos desconfortos visuais. Adicionalmente, notou-se que os pavimentos mais obstruídos, a exemplo do Térreo, foram os mais uniformes, porém com iluminâncias abaixo da faixa suficiente (INU <300lux). Quanto às variáveis do edifício, as fachadas orientadas para Noroeste e Nordeste apresentaram melhor desempenho, apresentando ambientes com menores variações das iluminâncias, percentuais satisfatórios de área iluminada acima de 75% de INU bem como maiores faixas de ofuscamento imperceptível. Diferentemente, a fachada Sudoeste registrou o pior resultado em relação aos níveis de iluminação e a Sudeste a mais propensa ao aumento da probabilidade de ofuscamento, sobretudo nos ambientes inseridos nos cenários com reflexão máxima das fachadas e em situações sem interferência do entorno, com a contribuição da luz direta.

Cuidados com a apropriação da iluminação natural e com sistemas de iluminação artificial cumprem importante papel na eficiência energética dos edifícios, no bemestar e na saúde dos seus ocupantes. O Brasil possui atualmente, em fase inicial de implantação, um programa de etiquetagem voluntária de edifícios, que deverá se tornar obrigatório em futuro próximo, com vistas à regulamentação e classificação de edificações eficientes em suas características de envoltória, iluminação e condicionamento de ar. Esta pesquisa diagnosticou os sistemas de iluminação natural e artificial das bibliotecas da UNICAMP, instaladas na Cidade Universitária Zeferino Vaz, para fazer recomendações em conformidade com as necessidades específicas do espaço e as orientações do programa de etiquetagem voluntária. Foram feitos levantamento cadastral, medições in loco com o auxílio da técnica das imagens HDR, aplicação de questionários e propostas de intervenção com o auxílio de simulações computacionais. A revisão bibliográfica situou o estado-da-arte relativo aos aspectos do objeto de estudo. Na Fase I, o levantamento cadastral permitiu levantar as condições atuais de todas as bibliotecas do campus. Na Fase II, as medições em nove bibliotecas permitiram conhecer aspectos quantitativos das iluminâncias e de distribuição de luminâncias no campo visual. A aplicação e a tabulação dos questionários permitiram colher as impressões dos usuários. Na Fase III, o exercício de projeto em uma das bibliotecas, com o auxílio das simulações computacionais, serviu para avaliar propostas de intervenção nos sistemas de iluminação natural e artificial.

Attention to both daylighting and artificial lighting systems plays a key role in the energy efficiency of buildings, the well-being and health of its users. Nowadays Brazil has a voluntary certification program for buildings, on initial deployment, which will become obligatory in the near future, aiming at the regulation and classification of building energetic efficiency, including lighting and air conditioning. So, this research made a diagnosis of daylighting and artificial lighting joint the libraries of the State University of Campinas (UNICAMP), at the University Campus Zeferino Vaz, to make recommendations in accordance with the specific needs of such spaces and following the guidelines of the referred voluntary certification program. The survey included cadastral registers, measurements in situ with the aid of the technique of HDR images, questionnaires and the development of a project with the help of computer simulations. The literature review showed the state of the art concerning the aspects of the subject studied. In Phase I, the cadastral survey allowed to find out the current conditions of all libraries on the campus. In phase II, measurements in nine libraries helped to understand the quantitative aspects of illuminance and luminance distribution in the visual field. The application and tabulation of the questionnaires allowed obtaining the users impressions about such spaces. In phase III, the development of a project in one of the libraries, with the aid of computational simulations, permitted the evaluation of some proposals for the refurbishment of the daylighting and artificial systems. The choice of samples for Phases II and III reckoned the heterogeneity of the spaces of the campus. The results of this survey will be formally conveyed to the managers of the university, for their deliberations about its implementations as part of the strategies concerning the improvement of supporting infrastructure. / Mestrado / Arquitetura e Construção / Mestre em Engenharia Civil
