During the cold months of autumn and winter, the most important thing is to keep warm. Some houses use electric heating. Others use roaring fires lit in the fireplace. A group of students from Japan creating something new and innovative. Their house uses straw to create heating.
Japanese students at Waseda University have designed and produced an innovative house made of straw that produces its own heat. It uses the process of agricultural fermentation. This process takes place as dried straw is composted in acrylic cases inside the house. In order to do so, the low-odor Japanese “bokashi” method is used. The fermentation process naturally heats up the house by generating 30° Celsius heat for up to four weeks.
During the summer months, the straw is stored inside transparent window shelves. These shelves are used in order to serve as “heat shield panels.” That means they release cool moisture as the straw dries. When the weather turns cold, the straw is moved inside for composting and to generate heat. The grass walls of the house need to be changed a few times per year. However, they regulate the temperature in the house in a completely natural way that requires absolutely no energy.
The self-heating house was designed by Masaki Ogasawara, Keisuke Tsukada and Erika Mikami. It was created as part of a project called “A Recipe To Live.” The house was built in the coastal town of Taiki-cho in Hokkaido. Taiki-cho is a dairy farming town that has many straw pastures, perfect for the development of the project.
The simple, sustainable, self-heating house was the winner of the 2011 LIXIL International University Architectural Competition. The house is a perfect blend of organic aesthetics and practicality. It is durable, but also has a pleasant design. Moreover, its cunning heating system that uses straw fermentation makes it perfect for those who prefer green designs. Would you like to live in such a house?
