The objective of this project is aesthetically realizing the dynamic and complex pattern of envelope, and technically enabling the elevation updated. This curtain wall system generally consists of two parts : one is the honey comb shape of glass panels and another is the dynamic shape of shading which fits to the panels. The irregular pattern of shading can be rotated 6 ti mes and each rotation generates different pattern while the general curtain wall consists of neat rectangular panels with repetitive pattern. Thus, this creates complexity of dynamic envelope by rotating just one prototype of shading.
