ANÁLISE DA EFICIÊNCIA ENERGÉTICA E CONFORTO TÉRMICO EM DOIS EDIFÍCIOS PÚBLICOS UNIVERSITÁRIOS

Abstract

The concern with the performance of the buildings, whether by the fulfillment of technical norms, or, more recently, by the implementation of measures that promote the comfort provided to the users, enhanced the interest in studying the influence of the constructive and environmental parameters. In this sense, the analysis of built environments, even with the same constructive techniques, but with divergences in relation to the users’ occupation, as well as to external factors, becomes relevant for the search of new solutions that meet the current and future needs of sustainability and efficiency for the buildings. This analysis is one of the objectives of this article, which aims to study in several aspects the energy efficiency of two public university buildings, in accordance with the Technical Regulation of Quality for the Energy Efficiency Level of Commercial and Public Buildings (RTQ-C - 2017). In addition, this study has the objective of analyzing the thermal performance of two rooms of the FEM (Faculty of Mechanical Engineering) of the University of Campinas, with opposite orientations, considering the perception of the users. The proposed methodology allows obtaining more plausible results for the study in concordance with the existing limitations, since it depends on the reliability of the answers provided by the occupants of the environments, as well as the data readings of the equipment allocated for the evaluation. Results were obtained through graphical analysis. The applied questionnaires show that the presence of better technology equipment, as well as external factors such as incident solar radiation on the building, associated to thermal preferences of users are floating factors and that the joint point relies on the typology of the built environment, which can attenuate the inefficiency of the other parameters.
