建築立面系統本身就是矩陣的太陽能板，因應外部陽光環境而調整自身360度角以獲取熱能最大化，在此同時也能為室內做高效的遮陽，向光特性如同向日葵的生物行為。

Architectural facade system comprised by an array of solar panel units. In order to gain the maximum solar energy, their orientation could be adjusted according to solar path by rotating in 360 degrees. Simultaneously, it also provide an efficient solar shading at the interior. This phototropism is similar to the creature behavior such as sunflower.
