Résumé:
The constant change in user preferences, along with the arrival of new products and services in the field of civil construction, resulted in the need to develop new types of personalized construction systems. In this context, industrialized construction systems emerged, especially the Light Steel Frame system, which in turn has as main characteristics the speed in the construction processes, rational use of materials, in addition to the commitment to sustainability. Given this scenario of the appearance of new constructive methods, it was necessary to establish normative criteria for the performance and comfort offered by the buildings conceived from them. The presente work aims to evaluate a low-cost hypothetical single-family residence, in terms of performance and thermal comfort, according to ABNT
NBR 15575 standard of 2013. Following the prescription of the standard, thermal evaluation was performed through a computational thermal simulation, using the EnergyPlus software. The same takes into account the geometric definition of the residence and its routines of use and occupation, in addition to the materials used in its construction elements and the climatology of the region in which it is located. Thus, it was possible to verify the main thermal variables, which influence the thermal comfort of users, and consequently on the thermal performance of the prolonged permanence zones of the residence, in view of the typical summer days. According to the analysis of the data obtained from these variables, and comparing them with the normative criteria, it is understood that the thermal performance of the building is classified as superior (S). It is also thought that the use of equipment and the routines of
occupation of the residence are factors of relevance for the thermal variation of the internal temperature of the rooms of the residence. Finally, it is believed that the use of computational simulations is the most viable way to analyze the thermal performance of a building in its design phase. Therefore, knowing this performance allows us to perform an energetic study, which in turn can enable the design of projects that provide thermal comfort in a natural way to building users.
