Another elegant solution is the wind catcher , or badgir , also originating from Persia. These tower-like structures rise above the roofline of a building and are designed to capture prevailing winds. Internal vertical partitions direct air downwards, often passing it over a pool of water or a qanat (an underground water channel) to provide additional evaporative cooling. Even when there is no wind, the temperature differential between the top and bottom of the tower can create a natural updraft, drawing hot air out of the building. Modern computational fluid dynamics simulations have confirmed that well-designed wind catchers can reduce indoor temperatures by up to 12°C compared to the outside.
Despite their efficacy, natural cooling methods have limitations. They require careful building orientation, local climate analysis, and often, larger land areas than modern high-rise construction permits. Nevertheless, a hybrid approach is emerging: ‘active’ cooling systems that work with passive designs, rather than against them. For instance, a building with high thermal mass can be mechanically ventilated at night to ‘charge’ the coolth, then sealed during the day. As the world seeks to decarbonise, these time-tested strategies are no longer a curiosity — they are a necessity.

In hot, dry climates, buildings made from materials with high ___________ absorb heat by day and release it at night. The Persians invented 7 ___________, which are tall structures that direct wind downwards, sometimes over water for extra cooling. In humid regions, houses on 8 ___________ allow air to flow underneath, and courtyards help regulate temperature. A more recent discovery is radiative cooling, where special white paints reflect sunlight and emit heat through 9 ___________ radiation at night.
