The “Cube” has been evolved in design process.It is transformed from its own form to another. In order to follow one of the required design elements, the form is orientedtoward sun angles to maximize the absorption of the solar energy. The Sun will beutilized to generate electric power through the installed photovoltaic panels on tilted roof area. So, the entire electric consumption of the building will be covered through this system except retail and coffee area at level 1. The energy will be gathered to the battery installed at level 4 and level 5, and it will be closely connected to the Photovoltaic Panels installed on the samelevels. In addition, inclined facade walls represent sustainable ideas of the material uses. It uses dual layered composite panels. Thewall unit iscombined with light weight precast composite panel at exterior, MDF panels at interior, and low-E dual glass in-between. It will limit the sun lights during day time and minimize heat transmittance to the interior space. Furthermore, exterior walls are transformed by its functional requirement for the use of rooms providing balconies and glass openings, and air ventilation openings at building core. Thus, the “Cube” is connected to another cube (Cube Annex). This is a transitional form to link the bridge podium (existing building design form) to the main ‘Cube’. This linkage not only amplifies the dynamic form of the Cube, but maintains the existing building design in harmony with the new icon as well.
