Conforto térmico de residência no semiárido paraibano: estudo de caso.

Abstract

Brazil is a country of continental dimensions with cultural characteristics, climate, availability of natural resources, among others. In this sense, it is very important to search for an identification of regional characteristics, placing the need to find a suitable building model for each bio-climatic region. This study aims to analyze the thermal comfort of a residence, designed by researchers at UFCG observing the climate needs of the northeastern semi-arid and built within the concept of sustainability. For the evaluation of thermal comfort data were collected air temperature, black globe and masonry surface, in addition to the relative humidity and wind speed. The samples were collected during the summer period 2016, climatically most adverse situation for the semi-arid region. The house was built in the rural municipality of Cabaceiras (PB). The data were collected under different treatments of handling the ventilation openings (windows, flags and cobogós). For obtaining and storage of climate variables weather stations have been constructed from a plate prototyping, “arduíno”, connected to obtaining climate variables sensors. Several Indexes of Thermal Comfort were used to characterize the indoor as well as an evaluation of thermal performance of the building edification.Comfort Index values were calculated using only thermal climatic variables (such as the Discomfort Index , Temperature and Humidity Index and Bulb Index Moist and Black Globe) and indices were calculated using climatic variables associated with individual parameters (such as the Middle Vote Estimate, People Percentage Unmet Temperature Equivalent Physiologic). The study points to the fact that it offers environmental comfort for most of the day, with slight discomfort in cold part of the morning time and a slight discomfort from hot temperature of the afternoon shift.
