Desempenho térmico das residências universitárias da UFCG do Centro de Ciências e Tecnologia Agroalimentar (CCTA), campus pombal-PB.

Abstract

The interaction between a building and the thermal environment that surrounds it defines the thermal performance of a building. Currently, much has been discussed about the importance of evaluating the thermal behavior of buildings, since the adequacy of a project to the climatic reality where it will be implemented, alleviates the appearance of thermal discomfort by its users. In learning environments, for example, thermal discomfort can directly interfere with student productivity and performance. As a result, as they were intended for student housing, it became significant to evaluate the thermal performance of the University Residences at the Center for Agro-Food Science and Technology (CCTA) at the Federal University of Campina Grande (UFCG), Campus PombalPB. The residences in question are located in a region with a hot climate and low humidity and are not artificially cooled. Unfavorable conditions for thermal performance in housing units can interfere with the learning of students who live there. The evaluation of the performance of the buildings was carried out using the computational simulation procedure proposed by NBR 15575/2013. Although a new version of this standard was published in 2021, the lack of time made it impossible to carry out the assessment of residences based on it. By carrying out the simulations, it was found that the thermal performance of the University Residences meets the minimum level. In order to provide alternatives for thermal improvements in the building, new simulations with ventilation and shading strategies were carried out. The simulation that presented the best results was the one that combined increased shading on the windows of long-term stay environments (APP) with a reduction in solar absorbance on the west wall of the residences, in which the thermal performance ceased to be minimal and reached the intermediate level. The insertion of shutters on the APP windows (shading strategy) and white painting on the west wall (solar absorbance reduction strategy) were the alternatives proposed to improve the thermal performance of the CCTA University Residences.
