Expressão arquitetônica e Estratégias Bioclimáticas: a infuência do clima na configuração da casa e na construção do repertório arquitetônico em Pilar-AL.

Abstract

The human intuitive search for shelter was the reason for their survival. In this process, the climate takes an outliner role, making the architectonic production unique, which finds in the house its greatest adaptive strategies repository. Even though, throughout history, this repertoire has been forgotten. Concerned about life and its maintenance, the bioclimatic approach constitutes a way to redeem and develop solutions that reinstate architecture and environment. Thereby, it reflects in the architectural design the climate and site consciousness, and embraces, in an interdependent way, the environment and life which singularizes it. The present work investigated the existence of a possible architecture and climate dialogue, born with the primary intention of dwelling in the tropics, through the embodying of bioclimatic strategies by the vernacular architecture of Pilar-AL. The methodology was based in a multiple case study and was developed based on the context and selection of six houses; survey and iconographic material production; measurement of air temperature and relative humidity data; creation of bioclimatic diagrams; simulation of wind and shading behavior; collected data processing and systematization of the results, in which comparisons between architectonic examples obeyed a qualitative approach. The results suggest an efficient bioclimatic response of the studied houses against the considered thermal comfort range in the evaluated period, shading and ventilation. The answers confirm the coherent use of verandas, crafted window design, porous internal partitions, wind permeable roofs, thick external walls protected from sun incidence and light inner walls. Therefore, it was possible to recognize, considering the work‟s limitations, an architectonic repertoire adapted to its climatic context and the importance of the constructive heritage to the cultural enrichment and the strength of the bioclimatic approach in architecture.
