Shaded draft loggia
Born in Egypt (Cairo), Arab world.
How it works
A covered sitting area at ground level, screened by a lattice between a sunlit courtyard and a cooler shaded garden. The temperature difference between the two spaces pulls a steady draft through the seat, so it stays breezy even when there is no wind.
In a modern home
A shaded, screened transition room or deep loggia set between a warm and a cool outdoor space to induce a passive draft through a living area.
