SOLAR ORIENTATION AND THERMAL GAIN OF FACADES IN DIFFERENT TYPES OF WEATHER IN THE CITY OF PALMAS - TO: SUMMER AND WINTER EPISODES

Abstract

Considering the tendency to verticalization of buildings in Palmas, Tocantins, this article reports investigation of the influence of solar orientation and types of atmospheric weather on the thermal gain in facades of a residential building in the city. For this purpose, procedures for checking sunlight, shading, temperature and thermal gain were used in the main facades of this building, in line with the monitoring of the types of weather present in summer and winter episodes. The results show that the thermal gain on the facade, which influences the thermal comfort in the building and the consumption of electric energy, can vary according to the time of the year, the types of atmospheric weather and especially according to the existing cloudiness. The patterns show in this study are more complex and contradict the logic that the west facade is always the most unfavorable from the point of view of heat.
