description Despite the many advantages of integrating bioclimatic concepts into architectural design, studies show that for most architects their actual application is difficult. This indicates the existence of a gap between academic knowledge and design practice, especially concerning natural ventilation. Many of the natural ventilation strategies are presented employing visionary designs that do not represent their performance indoors. The objective of this research is to verify the materialization of basic principles of natural ventilation through a simplified method, aiming to facilitate the understanding of these phenomena by students during the teaching of natural ventilation in universities and, later, its application in the architectural design. The methodology was divided into three stages. 1. Construction of a flexible and simplified physical model for use in natural ventilation teaching; 2. Experimental tests in the proposed model, regarding the impact of the location of the openings on the performance of the indoor airflow in buildings; 3. Computational simulations based on computational fluid dynamics (CFD) of the same scenarios evaluated by the simplified method, in order to prove the efficiency of the proposed model for educational use in. The experimental and numerical results verified compatibility between the two tools, showing that it is possible to use this simplified model for understanding basic principles of natural ventilation such as, for example, the definition of the location of openings.

Apesar das inúmeras vantagens da integração dos conceitos bioclimáticos ao projeto arquitetônico, estudos demonstram que para a maioria dos arquitetos existe uma dificuldade em sua real aplicação. Isso indica a existência de uma lacuna entre o conhecimento acadêmico e a prática de projeto, principalmente no que se refere à ventilação natural. Muitas das estratégias de ventilação natural são apresentadas por meio de desenhos visionários que não representam claramente o seu desempenho nos ambientes internos. O objetivo dessa pesquisa é comprovar a materialização de princípios básicos de ventilação natural por meio de um método simplificado, visando facilitar o entendimento desses fenômenos pelos alunos durante o ensino da ventilação natural e, posteriormente, sua aplicação no projeto arquitetônico. O estudo comparativo dividiu-se em três etapas a fim de comprovar a eficiência do modelo proposto para uso no processo de ensino: (i) construção de um modelo físico flexível e simplificado para uso no ensino da ventilação natural; (ii) ensaios experimentais no modelo proposto, com relação ao impacto da localização das aberturas no desempenho do fluxo de ar interno nas edificações; (iii) simulações computacionais com base na Dinâmica dos Fluídos Computacional (CFD) dos mesmos cenários avaliados pelo método simplificado. A comparação dos resultados experimentais e numéricos demonstrou uma compatibilidade entre as duas ferramentas utilizadas, mostrando que é possível o uso desse modelo simplificado para o ensino de princípios básicos da ventilação natural como, por exemplo, a definição da localização das aberturas.
