Summary
Summer tests on a small two-storey test building in Kut, Iraq, pair a south-facing solar chimney for passive ventilation with an earth-to-air heat exchanger and a direct evaporative cooler. The cooling setup lowered indoor temperatures by roughly 12–18 °C while raising humidity, and the chimney drove air change rates above 10 per hour around midday, falling to lower but acceptable levels by evening.
