ⓘ Circulating Air Fan [article] by Kris De Decker - The steadfast rotating fan has been employed to keep people cool since the eighteenth century, and it remains highly effective, requiring much less energy and providing more comfort than air-conditioning. Cooling people by increasing local airflow is at least ten times more energy efficient than refrigerating the air in a given space, and it also adds the benefit of a personally controlled thermal environment. If used in combination with air-conditioning, fans can lower energy use by 30-70%, even in incredibly hot climates or during heat waves.

ⓘ Gloria, the Medieval Heating System Still Used in Spain [article] - The firebox is located outside the house, often in a courtyard but sometimes on the street. The chimney is on the other side of the heated room. The warm exhaust gases from the combustion heat are led through one or more ducts that run under the floor of the heated room(s), and then rise through the chimney. The floor and the walls slowly radiate this heat into the room. In summer, a natural air current in the gloria cools the room(s). The expression “estar en la gloria” (to be inside the gloria), meaning that someone feels happy and comfortable, refers to this medieval heating system.
ⓘ Heat Storage Hypocausts [article] are underground furnaces on top of which granite stones are piled, to then release hot air through vents in the floor. By this means, a room can be kept warm for days with just one firing of the hypocaust’s furnace.
ⓘ Ondol [article] in Korean traditional architecture is underfloor heating that uses direct heat transfer from wood smoke to heat the underside of a thick masonry floor. The Agungi(아궁이) is the traditional fire place located at the kitchen area, and that is where the Ondol gets its source of heat.
ⓘ crimean ovens [article] are basically a firebox or oven on the outside of a tent, with a shallow, brick-lined, sheet-metal-covered trough running down the center of the tent’s interior, and ending in a chimney on the opposite exterior side of the tent. The tents are placed on ground with slight inclines, allowing the hot air to naturally rise and escape out the flue.
