AVALIAÇÃODONÍVEL DE CONFORTO PORMEDIÇÃOIN LOCO EM RESIDÊNCIAS UNIFAMILIARES SEGUNDOA ASHRAE 55/2017

Abstract

The major environmental changes on the planet in recent years, bring the challenge of building highperformance thermo-energy buildings to the civil construction market, associated the need for thermal comfort for users in the built environment. The objective is to evaluate the thermal performance of single-family homes, by measuring the variables involved according to the thermal comfort requirements of the user by the adaptive method established in ASHRAE Standard 55 of 2017. The results of the analysis of the comfort conditions of four buildings with different orientations and surrounding conditions highlighted the relevance of natural ventilation for the design of dwellings, especially in the bioclimatic zone 8, where it was necessary in some cases an air speeds above 0.6 m/s to adapt the operative temperature to thermal comfort. Given the importance of this strategy, it is worth continuing to improve thermal performance methods that consider natural ventilation. Since the new version of NBR 15575-1 now includes the simulation of natural ventilation, it is convenient to develop new studies on the sensitivity of the results of the evaluations in view of the use of this strategy, aiming at better thermal performance and also favoring user comfort .
