Estudio comparativo de envolventes y su relación con el confort térmico de un edificio de oficinas por medio de técnicas de optimización basadas en simulación. El caso del edifício A47, oficina de postgrados de la Universidad Nacional de Loja

Abstract

Abstract:The sustainable design of buildings seeks to minimize, counteract and even cancel the environmental impact generated in terms of the use, consumption and disposal of the resources involved in its construction and start up without sacrificing the thermal comfort of its users. Being the envelope the means of contact between the interior and exterior environments various studies have proposed to use thermal comfort without sacrificing the consumption of resources. In particular the envelope performance has also been studied based on the use of materials that, according to their mechanical nature, allow the envelope of a building top performance The objective of this research was to evaluate through optimization techniques based on simulation of alternative envelope scenarios for the thermal comfort of the A47 building, focused on the modification of wall and window materials Taking as a model the analysis of the development of Fanger for thermal comfort, the comfort zone required for the study case was established, temperature range that allowed, through trial-error, to conclude that the optimal solution is found in the enclosure insulation as well such as incorporating static shadow devices. The results are generally consistent with the background but are only extendable to the month of May. Precisely, this study is complementary testing the thermal behavior of the building the rest of the year (in its absence in periods of extreme weather) and also expanding the analysis to all the spaces that make up the case in question.
