This study aims to look at how atmospheres impact library rooms at the public library of Umeå and the public library of Östersund. The theoretical framework is based on Tuan’s theory of ”Space” and ”Place” as well as earlier research on atmosphere in library environments. The empirical material is a selection of observations and surveys made at the two libraries, in the facts department and the daily newspapers room. The method that is used is autoetnographical analysis made with thick description.  This study argues that atmospheres can change rapidly in different library rooms at different times, which impacts the library user in many ways. This purpose is achieved by using five atmospheric themes; light, sound, architecture, furnishings and human impact. The result indicates that library users were impacted by these five atmospheric themes albeit in different ways, depending on the room, the time and the subjective experience of the library user. This knowledge is useful for future library operations, due to the fact that atmosphere impacts the experience of a public library. The study articulates that The International Federation of Library Associations (IFLA) should include the importance of atmosphere in the IFLA manifesto.

The use of light has always been a vehicle of symbolic meaning and spiritual experience in religious spaces. Depending on culture and religion this use differs, but in any case, the connection between the built form, the architecture and the history makes the relationship with light a compelling issue that is worth exploring. This thesis aims to study the role that light played in the designing of St: Eskilskyrkan church in Sweden, and the way it affected the perception of the architecture and its materials. In order to answer this question, a methodology based on both qualitative and quantitative methods, was generated. Evaluation and discussion of literature review, interviews, survey on perception of light, a comparison between two similar buildings, daylight analysis using lighting software and testing lighting design tools are the key elements to create the guidelines for the lighting design proposal that will be generated in the last part of the thesis. This proposal aims to redevelop the existing illumination of the interior of the church, emphasizing on functionality, on the built form and the enhancement of spiritual experience.

This dissertation investigates the effect of the geometry of external shading devices upon light distribution, air flow pattern and thermal comfort, with direct application to the tropical hot-humid climates. A series of 30 different configurations of shading devices were evaluated under four different testing conditions, including overcast and clear sky for daylighting, and perpendicular and oblique winds for natural ventilation. The total of 120 tests on identical size scale models, was undertaken at the V.P.I. & S.U. Environmental Systems Lab via a low-speed wind tunnel (for air flow pattern) and an artificial skydome and real sky (for light distribution), with the use of conventional measurement devices. This research has made progress toward the goal of providing a framework to collect performance data and to display it in a graphical format, so that direct comparison can be made. This simultaneous reporting proved to be important since it facilitates a determination of whether natural lighting is being obtained at the expense of ventilation or whether the lighting has been sacrificed for ventilation, as related to human comfort. It demonstrates that no shading devices, either horizontal, vertical or combination, behave identically under identical conditions. Through the analytical model, this research has described a procedure by which designers can identify and select, from the performance data, the most effective use of shading devices based on their optimal characteristics. It provides the information about achieveable levels of performance of the given shading configuration and a prescriptive way on how that performance can be achieved. It also serves as a basis for a more systematic approach, and demonstrates that the amount of experimental work required to investigate the wide range of shading possibilities, while certainly formidable, is not excessive. / Ph.

Este trabalho foi realizado com objetivo de verificar se a aplicação destes sistemas, restritos a sistemas de iluminação lateral, no território nacional trariam de fato alguma vantagem para as edificações, no sentido de otimizar a iluminação natural obtida em ambientes profundos, em território brasileiro. As medições foram realizadas sob condição de céu real na cidade de Campinas, SP. A dissertação é composta por três etapas. A primeira, traz uma revisão dos princípios básicos necessários para o estudo das tecnologias utilizadas. Em seguida são apresentados alguns dispositivos de iluminação natural no cenário internacional, identificando suas características e os princípios físicos que determinam seu funcionamento. Na segunda etapa, mediante utilização de planilhas eletrônicas, determinou-se, para cada painel, a posição e o desenho mais adequados à latitude de Campinas para fachada norte. De acordo com estas especificações foram solicitados, no exterior, os painéis aos fabricantes. Na terceira fase, com um sistema de medição de iluminâncias, criado especialmente para esta tarefa, foram registradas as iluminâncias obtidas no interior de quatro protótipos, construídos na Universidade Estadual de Campinas (UNICAMP) utilizando-se os 12 diferentes painéis doados por universidades e empresas estrangeiras. Os painéis de iluminação natural foram acoplados à abertura dos protótipos, localizada na fachada norte. As iluminâncias obtidas com cada painel foram registradas de 8:00 as 18:00, de março a julho. Para que todos os painéis fossem medidos com condições de sol semelhantes foi realizado um rodízio de forma que a cada quatro dias todos os painéis foram acoplados aos protótipos e suas iluminâncias medidas ao longo do dia. Os dados são tratados de forma a obter valores médios mensais das iluminâncias, em função da profundidade do ambiente, onde foram realizadas as medições para dias claros, encobertos e parcialmente encobertos. A partir da comparação dos dados obtidos experimentalmente procurou-se estabelecer quais dos dispositivos estudados, iluminam o ambiente de forma otimizada em relação a um vidro comum de 3mm, criando uma iluminação mais homogênea ou conseguindo iluminâncias maiores no fundo do ambiente. O estudo mostrou que todos os dispositivos poderiam facilmente ser adaptados ao clima luminoso de Campinas, para fachada norte, no entanto cada um destes dispositivos tem as suas limitações e vantagens. Por fim uma solução ótima para alcançar um aproveitamento otimizado da luz natural dentro dos espaços, de acordo com os dispositivos estudados é sugerido na conclusão do trabalho / Abstract: The importance of this research relies on the quantitative evaluation of different daylighting devices, available in the international market, by means of acquiring the iIIuminance through models. This work was accomplished with objective of verifying the application of these systems, restricted to lateral iIIumination in national territory, if they would bring in fact some advantage for buildings, in the sense of optimizing the daylighting obtained in deep rooms, in Brazilian territory. The measurement has been made under real sky condition in the city of Campinas, SP. This thesis is composed of three stages. The first, brings a revision of the basic principies necessary for the study of the technologies used. Soon afterwards these daylighting devices in the international scene are presented, identifying their characteristics and the physical principies that determine its operation. In the second stage, by use of electronic spreadsheets, it was determined for each panel, the position and the most appropriate drawing for the latitude of Campinas for a North façade. In agreement with these specifications the panels were requested abroad from their manufacturers. In the third phase, with an iIIuminance measurement system, especially created for this task, the iIIuminance inside four prototypes were acquired, built in the State University of Campinas (UNICAMP), using the 12 different panels donated by universities and foreign companies. The daylinghting panels were coupled to the opening of the prototypes, located in the north façade. The illuminance obtained with each of these panels was registered from 8:00 to 18:00, from March to July. So that all of the panels were measured with the similar sun conditions so that every four days all of the panels were coupled to the prototypes and their iIIuminance measured during the day. The data are treated to get monthly average values of the illuminances, as a function of the depth of the environment, where the measurements were accomplished for clear, partially cloudy and cloudy days. From the comparison of these data we establish which of the studied devices can achieve a better performance if compared with a standard clear glass panel, and which can obtain a homogeneous iIIumination or greater iIIuminances along the deep of the room. The study showed that all the devices could easily be adapted to the luminous climate of Campinas, for the north façade, however each one of these devices has their limitations and advantages. Finally a new solution is suggested to reach an optimized exploitation of daylight in interior spaces, in agreement with the results obtained in the conclusion of this work / Mestrado / Edificações / Mestre em Engenharia Civil

O presente trabalho procura sistematizar o estudo sobre aproveitamento máximo da luz natural por meio do uso de um elemento da arquitetura passiva, a prateleira de luz (lightshelf), visando à redução do consumo de energia elétrica em iluminação artificial de salas de aula. Este tipo de elemento de proteção solar, colocado na parte superior da janela, favorece a distribuição e o controle da luz diurna e da luminância excessiva, proporcionando uma melhor percepção visual, quando houver quantidade e qualidade de luz suficiente. A partir do modelo reduzido de uma sala de aula pré-determinada do Centro Federal de Educação Tecnológica do Paraná, Unidade de Curitiba, foram testadas experimentalmente várias situações com as prateleiras de luz. A metodologia utilizada abrange as seguintes etapas: medições dos níveis de iluminamento com luxímetros digitais, em pontos pré-fixados no interior do modelo em escala reduzida da sala de aula; simulação das condições de exposição ao Sol, considerando diversos períodos do dia e épocas do ano por meio do uso de Relógio de Sol; análise de situações diversas do uso das prateleiras de luz; tabulação e análise dos resultados. Estas medições foram realizadas em três fases: (1) um pré-teste, com a finalidade de testar a maquete e o método proposto; (2) medições com as prateleiras de luz planas, cujos resultados foram comparados com algumas situações simuladas pelo computador, realizadas com a ajuda dos softwares ECOTECT e RADIANCE; (3) foram propostos novos tipos de prateleiras - côncava, convexa, côncava/convexa, e prateleiras planas com inclinação de 25°. As melhores configurações para estes novos tipos de prateleiras foram estudadas com o auxílio do software AUTOCAD 2002. Como resultado, observou-se que a prateleira de luz pode proporcionar iluminação natural mais uniforme, diminuindo o ofuscamento existente próximo às janelas, contribuindo para o melhoramento do balanço do brilho do espaço. Observou-se também que, com os tipos de prateleiras estudados no AUTOCAD 2002, houve um aumento da iluminação nos pontos mais distantes da janela. De acordo com os resultados obtidos, pode-se comprovar que o Sol pode ser usado como fonte de luz, desde que seja controlado por sistemas de iluminação natural bem projetados. / The purpose of the present dissertation is to organize systematically the study of adequate use of daylight by means of an element of passive architecture, the lightshelf, aiming at reducing electric energy consumption for artificial lighting in classrooms. This kind of solar shading element, placed at the upper part of a window, provides daylight control and its distribution, promoting a better visual perception, once there is sufficient daylight, qualitatively and quantitatively. Using a scale-model of a chosen classroom of the Centro Federal de Educação Tecnológica do Paraná, Curitiba, different situations were tested with a lightshelf. The used method comprehends following steps: illuminance measurements with digital luxmeters, in prefixed points inside the scale-model; simulation of solar exposition conditions, considering different periods of the day and of the year using sundials; analysis of different situations of lightshelves; data tabulation and analysis. These measurements were carried out in three phases: (1) a pre-test, aiming at testing the procedure; (2) measurements with horizontal lightshelves, comparing results with computer simulations with ECOTECT and RADIANCE; (3) innovative lightshelf types were proposed – concave, convex, concave/convex, and horizontal lightshelves with 25° tilt. Best configurations were studied graphically, with AUTOCAD 2002. As a result, it was noticed that the lightshelf might provide daylight more uniformly, reducing glare close to the window. Also, it was observed that with the innovative lightshelves, from the AUTOCAD study, there was even a daylight increase in the most distant points from the windows. According to the results, it can be proved that the direct sunlight may be used as a light source, once it is controlled by well-projected daylight systems.
