Over the centuries, architects have distanced themselves from the accumulated architectural knowledge, which often provided constructive solutions highly connected to the climatic context and cultural characteristics. With utmost expression from the 20th century on, building designers have assumed a somewhat negligent attitude towards the architectural project, essentially relying on active mechanical systems, to achieve indoor environmental comfort conditions. This paper overviews the current knowledge of solar control elements adopted and developed by Brazilian architecture, tracing its origin to the influence of Arab and Moorish architecture, with the objective of valuing passive solutions. Arab influence in Brazilian architecture began in the 17th century when Portuguese settlers felt the need to adapt the colonial buildings to the climatic constraints, particularly with regard to excessive solar radiation, leading to indoor thermal discomfort and excess natural light. Arab influence in Brazilian architecture remains present until the current day with the same objectives; however, it has been reinterpreted and appropriated by the Brazilian architectural school. Among the most used construction elements during the colonial period were the muxarabis, rótulas, and gelosias. Throughout the 20th century, these elements were culturally appropriated and served as inspiration for the development of the cobogó and the pioneering use of brise-soleis in Brazilian architecture. These elements have spread throughout global architecture, accompanied by the adoption of computer-controlled dynamic solar protection systems. Therefore, it is important to promote traditional solutions and encourage new architects to adopt passive approaches, aiming for energy efficiency and reducing environmental impacts.

En las últimas décadas, debido a las alteraciones climáticas y la posible escasez de energía, muchos son los investigadores en los campos de la arquitectura e ingeniería civil que encuentran alternativas y estrategias pasivas que puedan mitigar esos efectos y establecer una relación entre arquitectura y clima. En este contexto, los elementos perforados, específicamente el cobogó, en el caso de gran parte de Brasil son una alternativa arquitectónica que puede ser usada para minimizar las condiciones climáticas adversas, pues pueden proporcionar ventilación natural permanente, así como protección solar, e iluminación natural. Delante de estos aspectos, se presenta una revisión bibliográfica sobre el origen, evolución e importancia de los elementos perforados (cobogós) y algunos aspectos que lo relacionan como elemento arquitectónico que auxilia en la adaptación al clima, influenciando en las condiciones de confort ambiental y eficiencia energética. Se utilizó el método de investigación bibliográfica – documental, con base en la búsqueda de fuente de datos académicos. Fueron analizados documentos en español, portugués e inglés, publicados de 2014 a 2016. Posteriormente fue aplicado el Teorema de Gauss e por fin, realizado el análisis de títulos y resúmenes de los documentos más relevantes sobre el tema. Se observó la importancia de los elementos vazados para la arquitectura, y la necesidad de la realización de nuevos estudios para evaluación de desempeño de este dispositivo, además de cuestiones estéticas muy abordadas.

O estilo denominado Urban Jungle consiste em incluir plantas e elementos ligados à natureza concentrados nos ambientes, além de elementos mais rústicos. A pesquisa em questão teve como objetivo o monitoramento de temperatura e umidade relativa do Andar 43 (urban jungle), localizado no edifício Mirante do Vale em São Paulo, de forma a avaliar a influência da vegetação no microclima interior. Para tal, foram levantadas informações in loco e realizadas medições com Data Logger Hobo UX100-023 e análise comparativa. Os resultados indicaram uma diminuição de temperatura de até 3°C e de até 30,6% de umidade relativ,a com o auxílio da vegetação.
