Global warming and the low-carbon era: We need a new heating system!
The staggering volume of carbon dioxide emitted by the use of fossil fuels has brought about global warming, which in turn has triggered abnormal weather conditions and other social and environmental problems. Amidst this crisis, Korea's unique ondol culture has grabbed the full attention of the global community as the source of clean green energy for the future.
Ondol heating systems found around the world
The ondol technology is being widely introduced in various buildings overseas, referred to by its new name "radiant heating and cooling system."
For example, an ondol-style heating system is currently being used at the Reichstag building in Berlin, Germany, to heat a floor surface of 7500㎡.
Fondation Louis Vuitton in Paris, France, has also embraced the ondol technology.
Meanwhile, in Northern Europe, an increasing number of buildings and structures that are sensitive to temperature and humidity, such as airplane hangars, childrens' hospitals, and indoor stadiums, are opting for ondol.
Strengths of the traditional ondol that can end the era of global warming
The ondol is a Korean invention that has even been listed in the Oxford English Dictionary.
Unlike the Western heating system, which works by injecting warm air, and Japan's tatami culture that merely blocks out the cold, the ondol breathes warmth into rooms and retains it. Its strengths can be clearly seen in Semiwon, the world's first greenhouse to use the ondol technology that preceded Europe's first heated greenhouse in Heidelberg, Germany, by no less than 170 years.
A green technology that boasts high energy efficiency thanks to its eco-friendly and scientific heating method
The ondol system is designed in such a way that even when no fire is burning, the heat stored by the floor can be used to warm the rest of the room, making it highly energy-efficient.
It also has an excellent "bake-out" effect, which is known to improve the quality of indoor air.
Meet many other stories of the ondol, the source of eco-friendly and scientific heated energy.
