Bioclimatic buildings strategies for the climate of Araras city, São Paulo - Brazil

Abstract

The concept of bioclimatic architecture or passive solar architecture can be defined as an architecture that includes the climate as an important variable in the design process. Through the use of bioclimatic strategies the environment comfort can be obtained naturally for users of buildings, which depending on the climate, the construction techniques and the type of use. Considering these aspects, the main objective of this work is to identify bioclimatic strategies for buildings for the climate of Araras city, countryside of São Paulo State - Brazil, based on climatic characterization of the city and in the study of design guidelines indicated by the Brazilian Code NBR 15220-3, the Brazilian Bioclimatic Zoning. According to the code, the climate of Araras is inserted in Bioclimatic Zone 4. For this climate the main indicated strategies for winter are the use of solar passive heating and massive internal walls in buildings. For summer, the use of evaporative cooling and ventilation are indicated. Based on this information were established initial guidelines for thermal comfort and energy efficiency for projects of buildings in the climate of Araras-SP.
