An earth sheltered house in Switzerland (Peter Vetsch) An earth shelter, also called an earth house, earth-bermed house, earth-sheltered house, [1] earth-covered house, or underground house, is a structure (usually a house) with earth against the walls and/or on the roof, or that is entirely buried underground.
Current Earthship designs like the global module have a "double greenhouse" where the outside glass is angled toward the equator, and an internal glass wall forms a walk way or hallway as you step into the Earthship. This greenhouse is primarily used to grow food; it also creates a barrier for the 'comfort zone' inside the house.
The house was heated by a system designed so that Glauber's salt (a form of sodium sulfate) was allowed to melt in a solar-heated space. During the day, fans brought air through the warm space and via ducts out to the rooms of the house, at night air was brought through the same space where the salt then cooled and released its stored heat.

A dormer window (also called dormer) is a form of roof window. Dormers are commonly used to increase the usable space in a loft and to create window openings in a roof plane. [2] A dormer is often one of the primary elements of a loft conversion. As a prominent element of many buildings, different types of dormer have evolved to complement ...
The thermal conductivity of soil will influence the conductive heat transfer between the ground and heated or cooled slab-on-grade floors. Soils with moisture contents greater than 20% can be as much as 15 times more conductive than soils with less than 4% moisture content. [64] Water tables and general soil conditions should be evaluated.
It is less land-efficient than a two-story house but more efficient than a bungalow. Most sidesplits have a crawl space that is half the size of the house such that the foundation is the same for both halves of the "split" house. Some others may have a split foundation with a full basement below even the lower main living area. Backsplit
The zero-heating building is intended for use in heating-dominated areas. The purpose of the zero-heating building is to supersede net-zero energy buildings as a way to bring building-related greenhouse gas emissions to zero in the EU. Zero-heating buildings address flawed net-zero energy buildings: the requirement for seasonal energy storage ...
The temple of Ephesus was heated by flues planted in the ground and circulating the heat which was generated by fire. Some buildings in the Roman Empire used central heating systems, conducting air heated by furnaces through empty spaces under the floors and out of pipes (called caliducts) [4] in the walls—a system known as a hypocaust.
