National Underground America Day
國定地下日？！
Earth-sheltered architecture is a term that refers to the design and construction of different types of underground structures. An earth-covered home is a building with its roof covered in soil. This feature can not only absorb the rain water but also freshen up the air. Another type of underground house is called an in-hill home. Soil covers three sides of the building, while one side is left exposed for a door and windows. This design allows more natural light to enter.
覆土建築一詞是指不同類型地下建築的設計和建造。土屋是屋頂被土壤所覆蓋的建築物。這項特點不僅可以吸收雨水也可以淨化空氣。另外一種地下建築稱為靠崖式房屋。土壤覆蓋著建築的三面，有一面則顯露於外，供門窗使用。此設計讓更多自然光能透入。
