4.1 FUNDAMENTALS OF EARTH SHELTERED HOUSING

Hemisphere and north in the Southern Hemisphere), towards the aphelion (north) in the Tropics, or east just outside the Tropics. There is only one exposed wall in this type of earth sheltering, the wall facing out of the hill, all other walls are embedded within the earth/hill. This is the most popular and energy efficient form of earth shelter in cold and temperate climates.

Features of an in-hill earth shelter:

 Up to three walls covered  One wall is exposed to allow for a door and windows  Built above ground

In-hill homes are built into slopes or hills with one wall facing out while the earth covers

the other walls and the roof. These homes are typically built above ground. The exposed wall features windows to absorb passive heat from the sun. To effectively accomplish this, most in-hill homes are located in areas where the exposed wall can face south to absorb as much sunlight as possible.

Rooms that need natural sunlight like bedrooms, kitchens and living rooms are constructed closer to the exposed wall. Rooms that do not need daylight like storage rooms and bathrooms are commonly constructed farther away from the exposed wall.
