Estudo do desempenho térmico de parede de painel monolítico de EPS de uma residência unifamiliar do município de Dourados-MS

Abstract

Currently, individuals and organizations have increased their search for comfort and well-being, and a crucial factor is the temperature of the environment. To ensure human comfort, spaces must provide adequate thermal conditions, which are specified in the technical standard NBR 15575 (ABNT, 2021), which defines the minimum performance requirements for buildings, since the response of a building to external environmental variations and interior is influenced by the choice of materials and their thermal properties. Expanded polystyrene (EPS) has been widely used in civil construction due to its ability to thermally and acoustically insulate. Furthermore, its resistance capacity and its reaction to weather conditions make this material a relevant choice to improve the thermal efficiency of buildings. This study aimed to evaluate the in loco thermal performance of EPS as a sealing wall material in a residence in the city of Dourados, also comparing the thermal properties of the walls of EPS panels used with ceramic blocks. The methodology employed was comparative, and was divided into three stages: data collection, temperature measurement and calculation of the thermal properties of the materials. Performing the calculations of thermal resistance, thermal transmittances and thermal capacities of the materials, according to the procedures stipulated by NBR 15220-2 (ABNT, 2005), it was found that the seals have good thermal conditions. It is important to highlight that EPS was the material that performed better in relation to the other prototypes, meeting all the requirements established by the standard.
