Operating within a dense urban context, a public building recognizes the activities that are contained within its boundaries... further tying the place to a larger urban spatial sequence. / Master of Architecture

Neste trabalho é realizada a avaliação do desempenho solar e luminoso de chapas metálicas com diferentes padrões de perfurações empregados para proteção solar na envoltória das edificações. Foram ensaiadas experimentalmente as transmitâncias solar e luminosa em diversos ângulos de incidência de chapas metálicas, chapas expandidas e telhas metálicas, com ou sem pintura, planas ou com conformação espacial. Avaliou-se a relação entre a transmitância e % de perfuração da amostra para incidência da radiação em variadas alturas e azimutes solares, comparou-se o comportamento solar e luminoso de cada amostra e entre amostras com características semelhantes. As normas ASTM E972 Standard Test Method for Solar Photometric Transmittance of Sheet Materials Using Sunlight e ASTM E1084 Standard Test Method for Solar Transmittance (Terrestrial) of Sheet Materials Using Sunlight foram adotadas para medições de campo das amostras. Os resultados mostram que, para todas as amostras, as transmitâncias solar (TS) e luminosa (TL) na perpendicular se assemelham a % de perfuração da amostra; para ângulos diferentes da normal há uma redução conforme a altura solar diminui e que quanto maior for o furo em relação à espessura, menor será a redução. TS/TL decresce conforme a altura solar diminui, exceto para as telhas. Em relação à variação de azimute, para chapas perfuradas sem acabamento ou pintadas, os valores de TS e TL se mantêm praticamente iguais, enquanto que para chapas expandidas e telhas os valores variam. Para as amostras pintadas, TS e TL das amostras com cores claras são maiores do que das amostras com cores médias que por sua vez são maiores do que as amostras com cores escuras. A partir destes resultados e da elaboração da ficha de aplicação dos resultados para variados ângulos, no âmbito do projeto de arquitetura, contribui-se para o emprego apropriado deste tipo de material, além de complementar informações técnicas pouco disponíveis no mercado. Além disso, os dados medidos em campo podem servir de validação para modelagem computacional para uma variação maior de ângulos, e na avaliação de ambientes projetados ou construídos, os dados coletados, em especial os ângulos diferentes da incidência normal, podem ser usados em simulação energética ao longo do ano. / This research focuses on the evaluation of solar and optical performance of metal sheets with different patterns of perforations used as shading devices in the building\'s envelope. Solar and light transmittance were experimentally tested at normal and off-normal incident angles of samples of perforated metal sheet, expanded metal sheets and perforated tile, with or without painting, flat or volumetric shape. The relationship between % perforation of sample and transmittance for off normal angle incidence (height and azimuth) was evaluated. Solar and optical results were correlated for each sample. Samples with similar characteristics such as perforation, painting, hole dimension were compared. ASTM E 972 Standard Test Method for Solar Photometric Transmittance of Sheet Materials Using Sunlight and ASTM E 1084 Standard Test Method for Solar Transmittance (Terrestrial) of Sheet Materials Using Sunlight were adopted for field measurements of the samples. The results show that for all samples, the solar transmittance (TS) and light (TL) perpendicular to the sample is similar to % perforation; for off normal angles there is a reduction as the solar altitude decreases and that the higher the hole relative to thickness, the smaller the reduction. TS / TL decreases as solar height decreases, except for the tiles. Regarding the change in azimuth for perforated sheets with or without painting, the values of TL and TS remains practically the same, whereas for expanded metal and tiles values vary. For the painted samples, TS and TL bright color of the samples are higher than the intermediate color samples which are in turn higher than the samples of dark colors. From the results achieved and with the development of the application table to diferente incident angles, within the architecture field, these results provide information for the appropriate use of such material, plus some additional technical information available in the market. Furthermore, the data measured in the field can serve as validation for computational modeling to a wider range of angles, and also it could be used in buildings\' energy simulations.

The aim of my master´s thesis is a new sports center project in Havlíčkův Brod in neighborhood of sports complex Na Losích on plot no. 561/1, 564/17. The land is slightly sloping and their total area is 12574 square meters. The building of the sports center is designed as a two-storey, with a cellar, with a dominant part of the multipurpose sports hall. The vertical supports construction consists of a reinforced concrete monolithic combined system. In the sports hall, the supports construction consists of a skeletal structure made of steel rolled elements in combination with reinforced concrete monolithic columns. Vertical peripheral construction are equipped with thermal insulation system with perforated sheet metal. The foundation building construction is designed as a monolithic foundation slab serves as a white bath. The horizontal supports construction are designed from prestressed SPIROLL slabs. The roof construction is designed as a single-layer vegetation flat roof. The roof supports construction of the sports hall is designed from steel-truss girder with supporting trapezoidal sheet. The designed sports center has 3 functional parts. It is a multifunction sports hall with facilities for athletes on the underground floor. The second functional part on the first floor is a sports bar connected with the main entrance hall and a bleacher with a capacity of 400 persons, which is located in the sports hall. The third part consists of a separate section on the first floor for athletes using the adjacent outdoor playground and the main part is located on the second floor, which serves as a facilities for TJ Jiskra club management, then there is a VIP zone, a clubroom and a small exercise room with facilities.
