Proposta de cobogó para fachadas com foco no controle de passagem de água da chuva

Abstract

The breeze block is a very present and important element in the iconography of Brazilian culture and, by allowing the passage of natural light and ventilation, its use contributes to more effective energy management in buildings, a topic that is so often discussed in times of the rise of sustainability. With this in mind, this work aimed to develop a breeze block for use on facades that would reduce the entry of rainwater from the outside into the interior of buildings. To this end, a bibliographical research was first used as a basis for contextualizing the work. To develop the project, the design methodology of Löbach (2001) was used, which is divided into the phases of Preparation, Generation of Ideas, Evaluation of Alternatives and Implementation of the Solution. Thus, the study of the historical development of the product was carried out, and analyses of its function, configuration, structure, market and materials and manufacturing processes were performed. As a result, the Cobogó Ondas was obtained, a breeze block with upper protection and a slope at the base to allow water drainage. Its pattern was inspired by the beaches of northeastern Brazil, famous for their unique beauty. Furthermore, a simple rainwater simulation test was performed with a 1:2 scale model, which demonstrated that the product is capable of meeting the project's objectives. From the initial test result, 9 1:6 scale models were made in resin in order to demonstrate how it would be used in a real context and environment. Finally, it was concluded that the project's objective was successfully met and that the breeze block is as relevant today as it was when it was created.
