A RELEVÂNCIA DA ESTRATÉGIA VENTILAÇÃO NATURAL PARA PAULO AFONSO/BA/BR

Abstract

A ventilação natural é recomendada como uma das principais estratégias bioclimáticas para se obter conforto térmico no nordeste do Brasil. O objetivo foi verificar a relevância dessa estratégia para Paulo Afonso/ BA/BR. Compararam-se cartas bioclimáticas geradas por dois softwares, com base em dados do INMET, para o ano climático de 2016, com o modelo de conforto térmico adaptativo. A ventilação natural mostrou- -se fundamental para um considerável intervalo de horas do dia ao longo do ano, mas em conjunto com outras estratégias. O Analysis Bio apresentou maior proximidade com o preconizado pelas normas ABNT que o Climate Consultant. As estratégias passivas apresentam papel promissor para as condições climáticas da Z7. O ar condicionado não é recomendado como estratégia ativa principal, contrariando as práticas e preferências locais.

Natural ventilation is recommended as one of the main bioclimatic strategies to obtain thermal comfort in northeastern Brazil. The objective was to verify the relevance of this strategy for Paulo Afonso/BA/BR. Bioclimatic maps generated by two software were compared, based on INMET data, for the 2016 climate year, with the adaptive thermal comfort model. Natural ventilation proved to be fundamental for a considerable range of hours of the day throughout the year, but in conjunction with other strategies. Analysis Bio was closer to what is recommended by ABNT standards than the Climate Consultant. Passive strategies have a promising role for the Z7 weather conditions. Air conditioning is not recommended as a main active strategy, contrary to local practices and preferences.
