“Light and Colour” can be approached from deferent perspectives such as science, art or philosophy, entering an endless internal discussion in each one of them as well as among each other. “Coloured Glazing” of nowadays buildings facades is also an issue of interest for contemporary Architecture. This study is discussing the relation in general, of colour -as inseparable component of light –with architectural design, while maintaining focused on Coloured Glazing and its impact on human habitation. Today the term “Glass Building” is common in architectural praxis, describing the type of building with facades exclusively composed by glass panes. Major progress in glass technology has given to architects, a building material combining tectonic, economic and ecological advantages, development triggered mainly by the 70s oil crisis and the emerged need for sustainable energy consumption. The effect of coloured glazing on visual perception indoors, is the main axis of the research undertaken by this study, on the basis of daylight colour interpretation and its influences on habitation and labour. Our world is constantly changing. Differened perspectives are producing a variety of new “realities” colourful and shiny, mainly introduced by architects. The questions arising now are concentrated in spacial qualities indoors. Nevertheless Architecture is the only “art” obligated to functionality and cost effectiveness, thus based on human scale and anthropometry.
Subsequently, several “Glass” buildings were isolated in Athens and colour films were installed on a window in an office at University of Thessaly, in order to suit the corresponding statistic research. The study’s results, were supported from statistic analysis of subjects glass colour preferences depicted on answer sheets in situ.
The relevance between CCT (Corresponding Colour Temperature) of daylight indoors -throw glass panes- and the subjects preference, was, once again, strongly designated.
Yet, the ultimate objective achieved by present study’s conclusions is to step forward the proposal of colour design, as an inherent element in overall architectural design procedure, from the point of making strategic conceptual decisions up to sculpturing the details.
