Resumo
Este estudo apresenta uma perspectiva da ‘janela’, como o dispositivo mais
frequente de iluminação, na sua evolução e significado na arquitectura. A sua capacidade de
caracterizar tendências e estilos arquitectónicos, permanece desde as primeiras referências
históricas até aos elementos desenvolvidos e associados à iluminação natural dos dias de
hoje.
O interesse por este tema surgiu, principalmente, por ser o elemento arquitectónico
que desde sempre permitiu a entrada de luz natural nas construções. Foi sempre um dos
pontos de ligação e relação do interior com o exterior. Em determinadas situações tornou-se
num elemento tão discreto, que nos passou despercebido, além de ter sido ocasionalmente
desvalorizado.
A janela ou dispositivo de iluminação natural, quando utilizado correctamente pode
trazer muitos benefícios à arquitectura, assim como proporcionar conforto térmico sem
necessidade de gastos energéticos excessivos.
This study presents an overview of the ‘window’, as the most common lighting device, in its evolution and meaning in architecture. Its ability to characterize trends and architectural styles remains from the earliest historical references to the elements associated with the developed and natural light of today. The interest in this subject arose mainly because it is the architectural element that has always allowed the admission of natural light in buildings. It has always been one of the points of connection and relationship between the interior and exterior. In certain situations has become an element so discreet that became unnoticed, and has occasionally been devalued. The window or natural light device, when used correctly can bring many benefits to the architecture as well as provide thermal comfort without excessive energy expenditure.
