サバンナ地帯に生息するシロアリの巣は、昼と夜の寒暖の差が非常に激しいにも関わらず、温度を常に30℃に維持している。それは、湿度の調整やガス交換をすることができる土が持っているとても小さな孔と、アリ塚自体の構造によるものである。シロアリの巣の地上に出ている部分は数メートルだが、地下には数十メートルの蟻道と呼ばれるトンネルがあり、蟻道の下にある地下水によってトンネル内の土が湿って涼しくなっている。この蟻道は煙突のように地上に出ているトンネルとも繋がり、風が巣内部に入ると冷却され、それと同時に換気も行われる。
自然冷却の仕組みを取り入れた建物に応用されている。調湿機能を持った壁材開発に応用されている。
シロアリの巣の構造を利用して、快適な住居や倉庫の開発に応用できる。
