Internal lighting: Making indoor lights become the facade's light

Nighttime office building, with no lighting fixtures installed on the exterior walls. The entire nighttime expression of the building comes solely from the light emanating from the interior. The ceiling lights and task lights on each floor within the glass curtain wall form regular horizontal light bands; some floors are fully lit, some are half-lit, and some are completely dark, creating an irregular checkerboard of light and shadow. Silhouettes of interior beams, columns, ceilings, and furniture are vaguely visible through the glass. The building's mass appears volumetric in the night due to these internal lights, rather than being a surface illuminated from the outside. The ground floor lobby is the brightest, serving as the visual focal point of the entire building. The color temperature is the neutral white of interior lighting, approximately 4000K. Avoid: installing any floodlights or light strips on the exterior walls, allowing the glass to reflect external light sources, depicting all floors as equally bright, adding colored light.

夜間的辦公建築,外牆完全沒有安裝任何照明燈具,整棟建築的夜間表情全部來自室內透出的光。玻璃帷幕內每一層的天花燈具與工作燈形成規律的水平光帶,有些樓層全亮、有些只亮一半、有些全暗,形成不規則的明暗棋盤。室內的樑柱、天花板與家具剪影透過玻璃隱約可見。建築量體在夜色中因為這些內光而顯出體積,而不是被外部打亮的表面。地面層的大廳最亮,是整棟建築的視覺重心。色溫是室內燈具的中性白,約 4000K。避免:在外牆加裝任何投光燈與燈條、讓玻璃反射外部光源、把所有樓層畫成一樣亮、加入彩色光。
