When glass applied to the building exterior, the most common applications were curtain wall. However, glass is seen less simply thesedays. One aspect of this is the transformation of curtain walls from two-dimensional surfaces to three-dimensional.
folding glass facade
One example are folded glass facades, which take once-modular components of glass and steel and make them appear more malleable. Barkow Leibinger Architects‘ Trutec Building in Seoul, Korea synthesizes the modular and the folded by taking a regular rectangular grid and infilling the cells with a prismatic pattern of triangular and trapezoidal glass panes. It creates an irregular but relatively consistent pattern across the main facade.
The pattern of the dynamic glazing refracts light and image, which abstracts both the building’s surface and the views out of the building.
lighting dichroic discs
UN Studio designed colored bubbled wrap like shell for the trendy department store in Seoul Korea. The exterior skin is actually formed of 4,330 overlapping glass discs, 33 inches in diameter and a half-inch thick, withe LED lights behind it. The LED lights can change the color of each of the discs and create vivid play of colors and graphics to be displayed. The color of the facade changes from green to amber, depending on the position of the sun and the viewing position. At night the discs are individually backlit and controlled by a computer program to create color schemes so that the building makes a complete transformation during the day and evening.
“The subtle daytime looks of the building during day, changes to something completely expressive and outgoing during the night”, says lighting designer Rogier Van der Heide.
Eckelt Glas gmbh
The architectural challenge of spherically curved, frameless glazing has previously been unachievable worldwide. Following pre-qualification negotiations by the owner and architects with ECKELT GLAS, the glass units were modeled using computer software and a number of specially constructed prototypes, providing verification of the complex geometrical forms. Architect Herzog de Meuron and ECKELT GLAS eventually arrived at a successful modification of the VARIO system, which incorporates aesthetic as well as technical requirements such as earthquake safety, fire-protection etc. There were a total of 224 “bubbles” specially finished for PRADA store in Tokyo, Japan.
