Parametric design is a computer aided approach where set of parameters in a relationship, using algorithms form an expression. It helps in bridging the gap between ‘design intent’ and ‘design response’ (Rynne & Gaughran 2007, Schnabel 2007). The relation between various elements in a complex structure or geometry could be manipulated, and its effects could be studied easily. in architecture and urban design it has been used in different ways: from considering energy efficiency to testing structural strength of challenging geometries; from different complex functional relations between spaces to management of construction project with changes in spatial parameters such as height of the building (Jabi 2013, Stavric & Marina 2011). While this tool caters these different varied applications, parametric architecture, in particular, is apparently characterized by their stylistic formal expressions, which have become widely popular. These computer generated forms most of the times provide the user new, out-of-the-box spatial experiences. The resulting forms of parametric architecture, which are physical structures, have a unique bearing on its visual perception by the viewer or user. However, not much research has been done to understand this relationship of how or to what extent the visual perception of parametric architecture is affected by the change of the parameters. Is there a way to measure and realize the effects of this type of formal expression of parametric architecture as far as visual perception is concerned. And it has already been discussed that this visual perception impacts human cognition, decision making and emotions. The relationship between visual perception and parametric design is quite fuzzy till date. Continue Reading …
