Rainwater and Dirt: How Surfaces Stay Clean

A detailed cross-section illustration of the exterior wall finish of a futuristic minimalist building, showing how the white surface remains clean for many years: the roof edge slopes slightly inward to prevent rainwater from flowing down the exterior wall; an invisible drip edge is hidden on the underside of the cantilevered volume; and a recessed drainage channel is located above the window joint. The exterior still appears complete and seamless white. Presented as a clean architectural cross-section line drawing with light color fills. Avoid: rainwater directly flowing down the white wall from the roof, exposed metal drip edges and flashings, too many dimension annotations and text in the image, or using a realistic construction photo style.

一張未來感極簡建築的外牆收邊剖面細部示意,呈現白色表面如何長年保持乾淨:屋頂邊緣微微向內洩水,讓雨水不沿外牆流下;懸挑量體的底面藏著一道隱形滴水槽;窗縫上方有內凹的排水溝。外觀看起來仍然是完整無縫的白。以乾淨的建築剖面線稿加上淡色塗層呈現。避免:讓屋頂的雨水直接沿著白牆流下、出現外露的金屬滴水板與泛水、畫面加入過多尺寸標註與文字、使用寫實的施工照片風格。
