Interactive Buildings…Exploration of Smart Material


Smart Materials are materials that respond to environmental stimuli, such as temperature, light condition, moisture, pH, or electric and magnetic fields with particular changes in some variables. For that reason they are often also called responsive materials. Depending on changes in some external conditions, "smart" materials change their properties (mechanical, electrical, appearance), their structure or composition, or their functions. These materials can be used directly to make smart systems or structures or embedded in structures whose inherent properties can be changed to meet high value-added performance needs.
Application of responsive material in Architecture definitely makes it more responsive, interacting, interesting and adaptable.


L'Institut du Monde Arabe
Architect: Jean Nouvel
Paris, France
In this Islamic Cultural building, Jean Nouvel developed an interacting façade system that responses to the outdoor light condition thus enabling the building interior to get adapted to the surrounding. Behind metal sunscreen with active sun control diaphragms .The huge south-facing garden courtyard wall has been described as a 60m 'Venetian blind'. It is an ocular device of striking originality, made up of numerous and variously dimensioned metallic diaphragms set in pierced metal borders. These diaphragms operate like a camera lens to control the sun's penetration into the interior of the building. The changes to the irises are dramatically revealed internally while externally a subtle density pattern can be observed. Thus the whole effect is like a pierced screen, giving significance and an audacious brilliance to this remarkable building."

The architects developed a grid system that allowed the building facades to be treated in a continuously changing and dynamic way, while simultaneously maintaining an overall site coherence, instead of being traditionally composed as a regularly repeating flat surface. Three cladding materials; zinc (perforated and solid), sandstone and glass have been used within a modular basis established by the triangular pinwheel grid. This fractally incremental system uses a single triangle, the proportions of which are maintained across the single tile shape, the panel composed of five tiles, and the mega-panel construction module composed of five panels. The unique quality of the pinwheel grid lies in the possibility of surface figuration and framing shapes to be independent from the grid's smallest component unit, the triangle.
