The main focus of this project is to investigate the energy consumption of the manufacturing lines in the car industry and look for the potential methods regarding energy saving. Special emphasis is put on the lighting technologies that can be used in the manufacturing processes. Two lighting technologies are tested in order to see which one has better performance and lower energy consumption. Fluorescent tube and LED tube are compared concerning illuminance, UV irradiance and power consumption. Economic evaluation is also conducted to exam the feasibilities replacing fluorescent tubes with LED tubes. Results of the study show that the LED tubes have much lower energy consumption than fluorescent tubes, produce more direct and „colder“ light, and have much lower UV irradiance. However, the payback period of LED is relatively long at current price situation. Since it is expected that the price of LED tubes will decrease in future, it is reasonable to predict that the LED technology will change the fluorescent one in many applications. The energy consumption has been estimated for two manufacturing lines which use different technologies to produce car underbodies. In order to identify the differences from the energy consumption point of view, some measurements are conducted, such as the consumption of electricity, compressed air, air for ventilation and cooling water. The measured results show a disproportion in the power consumption when the lines are in stand-by mode. This affects the energy consumption per produced unit significantly. The line that has a higher capacity and a lower power consumption in the stand-by mode has a lower energy consumption per produced unit when it is operating with lower production loading. So, in order to improve the energy efficiency, it is necessary that it works at as high volume as possible and to have the stand-by power consumption as low as possible.

According to the regulation announced by Bureau of Standard, Metrology & Inspection (BSMI) of Ministry of Economic Affairs (MOEA), lamp fixtures must follow safety and electromagnetic compatibility (EMC) standards. However, the self-ballasted fluorescent lamps in the fixture should only be approved by the safety test but not regulated by EMC standard. Obviously, fixtures without light bulbs do not generate any electromagnetic noise. Electromagnetic interference (EMI) comes from the fluorescent light bulb embedded with an electronic ballast which included an inverter with high-frequency switching. A variety of tests demonstrate evidently that a fixture with different self-ballasted compact fluorescent lamps may possibly violate the EMC standard, revealing the absurdity of the regulation. In fact, self-ballasted fluorescent lamps use mostly self-excited electronic ballasts. The operating frequencies for this kind of electronic ballasts can not be precisely controlled due to the influence of many factors. They are not operated at a specified frequency but in a frequency range. This means that the generated EMI spectrum is hardly predicted, especially when a fixture is fitted by light bulbs from several manufacturers. This research inducts the worst cases from numerous measurements on a fixture with 1 piece to 8 pieces of light bulbs, and then attempts to design an EMI filter for all cases. As a result, a lamp fixture with the filter at the line input terminal can suppress the EMI. As long as the consumer buys the lamp fixture which are installed with the EMI filter together with any bulb in use, EMI noise can comply with standard limits.

Espumas vítreas são materiais heterofásicos empregados para isolamento acústico e térmico e, comparadas a outros materiais, são leves e resistentes. As espumas vítreas podem ser preparadas a partir de vidros de embalagens, de tubos de raios catódicos e de outros resíduos como cinzas volantes. Resíduos de lâmpadas fluorescentes, classificados pela NBR 10.004-04 como perigosos devido à presença de mercúrio, têm características para serem utilizados na obtenção de espumas vítreas. A descontaminação deste resíduo torna possível seu envio para aterros controlados, no entanto faz-se necessário o desenvolvimento de processos que contemplem a utilização destes em produtos de interesse econômico, considerando o aspecto ambiental envolvido. Desta forma, este trabalho tem como objetivo preparar corpos cerâmicos a partir de vidro de lâmpadas fluorescentes descontaminado de mercúrio, com carbonato de cálcio como agente espumante, buscando o desenvolvimento e a caracterização de espumas vítreas. As variáveis processuais investigadas foram: percentual de agente espumante (2, 3, 4 e 8%); pressão de conformação (20, 30 e 40 MPa); temperatura de queima (700, 750, 800 e 850°C); taxa de aquecimento (2,5, 5,0 e 7,5 °C∙min-1) e granulometria do vidro (11,0, 29,0 e 91,0 μm). Foram monitoradas as seguintes propriedades: massa específica, porosidade, resistência mecânica e condutividade térmica. Destacam-se como resultados a combinação dos fatores temperatura de queima e percentual de agente espumante na determinação da expansão volumétrica, enquanto que a variável pressão de conformação não possui influência representativa. O melhor resultado obtido para temperatura de queima foi em 800°C no qual o teor de 3% de CaCO3 apresentou expansão de cerca de 600%. Diminuições na granulometria e aumentos na taxa de aquecimento induzem a diminuições na expansão. Os resultados mostram que todas as espumas vítreas obtidas neste estudo possuem massa específica (0,187– 0,282 g∙cm-3) compatíveis com produtos comerciais.

The following properties were monitored: density, porosity, mechanical strength and thermal conductivity. The results highlighted were the combination of burning temperature and percentage of foaming agent in determining the volumetric expansion, while the variable conformation pressure has unrepresentative influence. The best result obtained for burning temperature was at 800 °C in which the content of 3 % of CaCO3 showed expansion around 600 %.

Este estudo, de maneira cronológica, ilustra a evolução da iluminação nas edificações, considerando seus avanços em diferentes períodos da história. Também apresenta dados analíticos sobre a luz e como a fisiologia do olho humano percebe tais fatores. Devido a sua eficiência luminosa, as lâmpadas fluorescentes têm sido constantemente utilizadas em ambientes que necessitam de grande quantidade de fluxo luminoso e baixo consumo de energia elétrica. Desta forma, este estudo explica o princípio de funcionamento das lâmpadas de descarga de baixa pressão, tanto as fluorescentes tubulares quanto as lâmpadas de catodo frio. Embora pertencentes ao mesmo grupo de lâmpadas, há diferenças entre suas características técnicas - o que, por ventura, pode indicar maior ou menor eficiência em sua aplicação. Tais diferenças são fundamentais para que se possa descrevê-las e compará-las quanto a viabilidade econômica de sua aplicação. Assim, o objetivo deste estudo é apresentar o comparativo de dois tipos de lâmpadas de descarga de baixa pressão - as lâmpadas fluorescentes tubulares e as lâmpadas de catodo frio - quanto a sua eficiência e os benefícios da eventual substituição (retrofit), sem que seja prejudicada a qualidade da iluminação para a realização das tarefas pelos usuários das edificações. Com base nos comparativos técnico (das características peculiares destas lâmpadas) e financeiro (investimento, custos de operação e de manutenção dos sistemas de iluminação), foi possível calcular os índices econômicos como Payback, VPL (Valor Presente Líquido) e TIR (Taxa Interna de Retorno), e dessa forma, oferecer argumentos para tomada de decisão do investidor. E, devido ao seu maior tempo de vida útil e baixo consumo de energia elétrica, como resultado, verifica-se a viabilidade econômica para o catodo frio, com emissão do fluxo luminoso equivalente, indicando o retorno sobre o investimento inicial em 3,5 anos, com taxas de retorno de 34,30%, se considerado o período de vida útil da lâmpada / Abstract: The constant search for efficiency in lighting projects on buildings has involved professionals in the construction, engineering and architecture to look for reliable information that best suit the numerous artificial light sources available. This study, chronologically, illustrates the evolution of lighting in buildings, considering its advances in different periods of history. It also presents analytical data on the light and how the physiology of the human eye perceives these factors. Because of its luminous efficiency, fluorescent lamps have been constantly used in environments that require large amount of luminous flux and low power consumption. Thus, this study explains the operation's principle of low pressure discharge lamps, both as tubular fluorescent lamps and cold cathode. Although belonging to the same lamps' group, there are differences between its technical characteristics - which, perchance, may indicate a greater or lesser efficiency in your application. Such differences are fundamental so that you can describe and compare them as economic feasibility of its application. The objective of this study is to present a comparison of two types of low pressure discharge lamps - fluorescent lamps and cold cathode lamps - as its efficiency and benefits of possible replacement (retrofit), without hampering lighting quality for the building users' tasks. Based on technical (the peculiar characteristics of these lamps) and financial comparative (investment, operating costs and lighting systems maintenance), it was possible to calculate economic index as Payback, NPV (Net Present Value) and IRR (Internal Rate of Return), and thus, provide arguments for investor's decision making. And, due to their longer life span and low power consumption, as a result, there is economic feasibility for the cold cathode, with equivalent lumen emission, indicating the return on the initial investment in 3.5 years with rates of return of 34.30%, considered the lamp life span / Mestrado / Arquitetura, Tecnologia e Cidade / Mestre em Arquitetura, Tecnologia e Cidade
