Skylight Band: Light Descends from the Ridge

A continuous skylight strip along the ridge. It follows the highest ridge line of the curved roof, with a width of only sixty to ninety centimeters, extending through the entire main space; light falls directly from above, sliding down the curved ceiling on both sides, forming a continuous gradient from bright to dark on the curved surface. The curvature of the surface is readable because of this light. The position of the light strip moves on the ground throughout the day. Avoid: using point-like skylights, placing the skylight on a flat roof, making the sides of the skylight flat instead of curved, adding grilles and shading below the skylight to diffuse the light.

一道沿著屋脊開的連續天窗。它順著曲面屋頂最高的那條稜線走,寬度只有六十到九十公分,長度貫穿整個主空間;光從正上方落下,沿著兩側彎曲的天花往下滑,在曲面上形成一道從亮到暗的連續漸層。曲面因為這道光而讀得出曲率。一天之中光帶的位置在地面上移動。避免:使用點狀的天窗、把天窗做在平屋頂上、讓天窗的兩側是平面而不是曲面、在天窗下方加格柵與遮陽把光打散。
