Utterly Disappearing Services

A futuristic interior where no equipment is visible. The air conditioning outlet is a narrow groove of the same color as the surface; the return air is hidden behind a suspended volume; the fire sprinkler head is a concealed type flush with the ceiling; speakers are embedded beneath the surface; switches are sensor panels of the same color and curvature as the wall. No circular holes or grilles can be found on the entire curved surface.
Avoid: using square air outlets and louvers, exposed sprinkler heads and detectors, visible speakers and sensors, opening circular holes on curved surfaces for equipment installation.

一個看不到任何設備的未來主義室內。空調的出風是一道與表面同色的細窄溝縫;回風藏在懸浮量體的背面;消防撒水頭是與天花齊平的隱藏式;喇叭埋在表面之下;開關是一片與牆同色同曲率的感應面板。整個曲面上找不到一個圓孔與格柵。避免:使用方形的出風口與百葉、讓撒水頭與偵測器外露、加入可見的喇叭與感應器、在曲面上開圓孔安裝設備。
