AIST Stories No1

From AIST to the Innovative World10Potential as a construction material that controls humidity as if it were breathingRealizing a comfortable living space without using electricityMany of you may have experienced the chilly sensation of entering the main hall of a wooden temple or a storehouse with mud walls even in summer. Buildings such as houses were originally built to conform with the climate in a region in order that they were pleasant to live in or appropriate to store goods in. In Japan with its high humidity, various techniques have traditionally been implemented in order that people could endure hot and humid summers in a cooler manner. These included improving the ventilation by adopting a wooden structure or using mud walls to block off the sunlight.However, almost all of the structures of today are highly airtight, modern houses. Be it a household or an office, with living spaces being sealed by aluminum sashes, our lives are led while temperature and humidity are controlled using air-conditioners.In addition to climate change that has become a significant issue over the past 20 years, energy conservation and power saving have also become important issues since the occurrence of the nuclear accident that accompanied the Chief Senior Researcher, Materials Research Institute for Sustainable Development, AIST Chubu CenterMasaki MaedaThe traditional wisdom of a Japanese house is recreated using AIST technology!Humidity-controlling tiles: Spotlight on an eco-construction materialLeading the wayAIST!Our life and society will change in this way!Rooms could be maintained at an optimum humidity if humidity-controlling materials come to be widely utilized in residential construction. In summer, the air in the room would not be moisture-laden and sticky, and air-conditioner use could be reduced. In winter, on the other hand, an appropriate level of moisture could be maintained, which would be good for health and beauty. One can anticipate very substantial energy savings no matter what type of residence the material is used in.
