Determinação de envoltória em Light Steel Framing para Edificações unifamiliares em clima quente e seco. 2020. 27f. Trabalho de Conclusão de Curso (Graduação em Engenharia Civil) - Centro de Tecnologia, Universidade Federal do Rio Grande do Norte, Natal, 2020.https://repositorio.ufrn.br/handle/123456789/40509The construction sector is one of the employment sources that generates the most savings in Brazil, resulting in the development of cities, urbanization and the growing number of high-end buildings and enterprises. Aiming to reduce expenses with the high consumption of materials and the use of non-productive techniques, more efficient construction methods appear, such as Light Steel Framing (LSF), which is characterized by the use of metal structures with cold-rolled profiles using plates industrialized products, such as cement boards and Oriented Strand Board (OSB), filled with thermal and acoustic insulating materials. Combined with modernization in construction, the concept of sustainability becomes relevant mainly regarding the energy consumption of buildings, taking care to use passive thermal conditioning strategies according to the climate in which the typologies are inserted, promoting the best thermal performance and comfort to users. Thus, the present work aims to determine an adequate envelope in Light Steel Framing for the hot and dry climate, characteristic of the Bioclimatic Zone 07 (ZB7), in single-family buildings, from the thermophysical properties of the materials put in computer simulation, as guides NBR 15220: 2005 and NBR 15575: 2013. The empirical results were obtained in the EnergyPlus software and the unprecedented results in the QuickField program, being able to compare the values with the limits established in the standards under study, determining the type of wall and cover in LSF for the hot and dry climate through the calculation thermal transmittance (U), thermal capacity (C) and thermal delay (ϕ). For the roof, the properties respected the normative limits, while in the simulated wall, the thermal capacity diverged from the permissible values.Light Steel FramingZona Bioclimática 07Eficiência energéticaClima quente e secoPropriedades termofísicasbachelorThesisEngenharias, Engenharia Civil, Construção Civil, Materiais e Componentes de Construção
