Avaliação de elementos climáticos para fins de edificações em Campina Grande-PB.

Abstract

The knowledge of the climatic conditions of a city is the mainstay for the conception of construction projects: to inhabiting confortably built spaces depends on architectural formulations, that should be, besides satisfying the users's needs, fitted to the locality environmental characteristics. With these considerations in mind, it should also imply in the construction planning of low energy consumption buildings. Using meteorological data from determined day times - 9:00 h, 15:00 h and 21:00 h - of the period between 1995 and 1999, registered in the Embrapa station of Campina Grande city, Paraiba, Brazil, this research had as objective to offer subsidies for a better planning of constructions, through the behavior analysis of climatic elements, aiming the higro-thermal human comfort, as well as a better building energy performance. Besides the studies of the temperature, relative air humidity and ventilation, it was also investigated the effects of the real insolation and the maximum insolation reason (n/N) on the averages of the daily temperatures, for the recognition of a comfort zone for this climatic variable. The research observed that in the January afternoons thermal discomfort because of high temperatures occurred. In July, despite no high temperatures, there was higro-thermal discomfort from 18:30 h to 9:00 h for low temperatures and high relative air humidity levels in these periods of the days.
