Abstract

Natural light characterizes architecture in a complex manner, especially when considering its fluctuations and variations whenever we experience a transition or passage from a space to another. It also influences the comfort and the well-being of its occupants. This visual adaptation appears in a process that is translated into a spatio-temporal dynamics implying body movement from space to space. The literature review recognizes the lack of knowledge in the relation light-space-time. This research proposes to study this spatio-temporal relation existing between light and architectural space, to qualify an architectural promenade. It proposes to reconsider the design of transitional spaces by the spatio-temporal analysis of light, through in situ experimentation including filmic segments. The studied variables of this research take into account the qualitative and quantitative aspects of light such as luminance, time, contrast and brightness. It combines the use of a luminance-meter, a camcorder and the analysis of numerical images as a starting point for the assessment of spatio-temporal qualities of light. The resulting analysis, as well as the visualization of the dynamic experience of visual ambiances, will allow a classification of luminous transitional experiences. The architectural promenade is analyzed according to the diversity and relative intensity of luminous ambiances in relation to time, which allows the development of a descriptive analysis of visual perceptions through spatial transitions. This method of analysis and dynamic representation offers a potential to favour the design of spaces while encouraging and applying principles of luminous diversity in architecture.
