Through the extensive use of parametric technology and the study of animal physiologies, the facade design uses the intrinsic properties of Iguana respiration as its conceptual background. The breathing process of this reptile ultimately informed each component’s design and function from heat storage to the release of cool air, thereby developing a skin which responds to the climatic conditions of Torino. Within each component is a subset of information which controls aperture, allowing or inhibiting direct solar radiation into the interior of the apartment building. Environmental analysis and a component aggregation process results in a reticulated system of controlled geometries which improve the living conditions in a typical building construction.
