Abstract(s)
O modo como os edifícios são projetados, tem influência no seu desempenho térmico e no consumo energético ao longo da sua vida útil. As envolventes opacas e os vãos envidraçados assumem um papel de grande relevância para a gestão de recursos energéticos, sendo que, são nestes elementos que incidem maiores trocas de calor, bem como a ventilação. Neste sentido é importante os materiais a serem aplicados nas envolventes opacas e a orientação dos vãos envidraçados de modo a garantir o conforto térmico exigido no interior dos edifícios. No âmbito do presente estágio foram realizados projetos térmicos de três edifícios de diferentes tipologias, arquitetura e áreas de envidraçados, verificando primeiramente o cumprimento dos critérios impostos pelo regulamento, através do cálculo dos coeficientes máximos e verificando as necessidades nominais de arrefecimento e aquecimento, através da folha de cálculo da ITECONS. Após este estudo é analisada a influência da orientação solar dos vãos envidraçados no desempenho e conforto energético no interior do edifício. Os edifícios são analisados em todas as rotações de modo a avaliar os resultados em todos os cenários possíveis. Este estudo evidenciou que a orientação solar tem influência no desempenho energético dos edifícios e deverá ser considerada na fase de projeto, de modo a que os edifícios retirem o melhor aproveitamento da sua orientação.
The way buildings are designed has an influence on their thermal performance and energy consumption over their useful life. The opaque surroundings and the glazed spaces assume a role of great relevance for the management of energy resources, and these are the elements that affect the greatest heat exchanges, as well as ventilation. In this sense, it is important the materials to be applied in the opaque surroundings and the orientation of the glazed spans in order to guarantee the thermal comfort required inside the buildings. Within the scope of this stage, thermal projects were carried out for three buildings of different types, architecture and glazed areas, first verifying compliance with the criteria imposed by the regulation, by calculating the maximum coefficients and verifying the nominal cooling and heating needs, through ITECONS spreadsheet. After this study, the influence of the solar orientation of the glazed spans on the energy performance and comfort inside the building is analyzed. Buildings are analyzed at every rotation in order to evaluate the results in all possible scenarios. This study showed that solar orientation has an influence on the energy performance of buildings and should be considered in the design phase, so that buildings get the best out of their orientation.
