Thick walls and small windows: cool upon entering

A mud wall over fifty centimeters thick. The window is very small and positioned high, installed on the outer side of the wall, creating a deep window recess indoors, framed by glazed tiles or smoothed plaster. The window has a carved cast iron grille or a wooden screen. The wall itself stores coolness, feeling cool to the touch in the morning. Light enters through the small window, reflects once within the deep recess before entering the room, thus the interior is dim. Avoid: opening large floor-to-ceiling windows, making the wall thin so the window recess lacks depth, making the interior bright and uniformly lit, using modern aluminum windows and glass.

一面超過五十公分厚的土牆。窗開得很小而且位置偏高,裝在牆的外側,因此室內有一段很深的窗洞,四周包著釉磚或抹平的灰泥;窗上有雕花的鑄鐵格柵或木格屏。牆本身蓄冷,早上摸起來是涼的。光從小窗進來後在深窗洞裡反射一次才進到房間,因此室內是暗的。避免:開大面積的落地窗、把牆做薄讓窗洞沒有深度、讓室內明亮均勻、使用現代的鋁窗與玻璃。
