Daylight is dynamic and dependent upon weather conditions; unfolding with both subtle and dramatic variations in qualities of light. Through a building’s apertures, daylight creates a connection between the space inside and the world outside. The aperture or window itself constitutes the frame that simultaneously separates, and connects us to our surroundings.
One can say that the world outside projects itself into the interior space, essentially as diffused illuminating reflections. As figuratively abstract and blurred phenomena, these diffused luminous reflections rouse us into interactions with the world.
In contrast to fluctuating daylight, a specific distinctive feature of artificial light has been – until very recently – its constancy in colour and intensity. However, by virtue of the technological convertibility of LEDs in concert with digital control systems, LEDs are capable of dynamically producing variations in colour and intensity in ways that correspond to our experiences of the daylight. Daylight and artificial lighting are thus positioned in a new relationship to one another.
Metaphorically, one can think of the adaptive software as ‘digital weather’ – as a self-generating and shifting cloud, with which to determine dynamic compositions of colour temperatures and luminous intensities.
The presentation will demonstrate a fully functional adaptive lighting design system, which enables sketching from user experience in full-scale participatory lighting design encounters.
