The curtain wall was a promise: a building that could wear any climate like a suit. Fifty years on, the suit has become the uniform of every city centre on earth.
Glass does not know where it is. It reflects its neighbours, blinds its occupants, and cools itself by cooking the street. A wall that ignores the sun has surrendered the oldest job in architecture.
We are not arguing for nostalgia — only for walls that know what season it is.
