COLOUR AND LIGHTING TECHNOLOGIES FOR MEDIA FAÇADE

Inside the research “Colour and light in architecture” at IUAV University, one of the main topics is to study the role of chromatic and luminous technologies in media-architecture.
The contemporary environment and architecture seems to replace any architectural project not identified by information and electronic technologies in order to realise dynamic and advertising architectural surfaces. The use of some software and digital displays in the architectural façade is completely changing the meant and the perception of the architecture in many point of view: architectural, urbanistic, sociological, etc.
In this architectural outline, which role will be able to have the urban-screen? Which will be the materials and the technologies involved on the realization of colour? And, especially, which capacities/competence will be necessaries, besides those of the architect, for this new trade?
Another important question is relative to the used materials and the visibility of the architectures: which kind are the colours for the realisation of these urban screens: colours of the additive or subtractive sintesys – RGB, CMYK? And, which type of image is it transmitted high/low resolution, 2D/3D? The scope of this paper is report some research goals in relation of the realization of media surfaces and, therefore, to analyze the variability of their perception and visibility related to the environmental effects, of the technologies and materials.
