Abstract:
In the field of architectural façade design, the most advanced research seems to be directed towards the development of active, adaptive, and dynamic façade systems. These are highly performative, but, at the same time, relatively expensive requiring more maintenance than static façades. Sometimes, for economic reasons, a dynamic façade is not really feasible, but the designer still wants to pursue a dynamic effect. In these cases, designers use different strategies, e.g., relying on colour to get the desired effects. The goal is to create building façades that exploit colour technologies to obtain a chromatic effect of movement or dynamism even though they are to be built with static elements. The cultural references for this kind of design seem to be drawn from art, and, in particular, from Optical Art. The aim of this paper is to propose a classification of the chromatic strategies used by designers to achieve dynamic effects on static façades. Significant examples of buildings will be presented.
