Efficient Heating and Insulation

Searching for an affordable pot belly stove ,would place a chute going up

This would serve to help heat the cabin . We have thought of making the cabin partially also surrounded

by the earth for insulation. A pot belly stove and in summer a humidifer would be needed of course

(sandro thought of a small solar system to run the humidifier )




The uk article states the future owners would be paying 150  a month to heat  this 3,300 sq feet house ! Thats inceredible


The technique the bow shed would be using is called Eart Bermed homes

That means it is built largely above ground and then the earth is piled on them ,all the way to the top to provide a protective coon of earth and vegetation.

The elevational style, strictly speaking, is neither underground nor bermed, but is more of a combination of both. Elevational homes are built directly into hillsides or mountainsides, looking almost as if they have been inserted into the mouth of a cave, to enough depth to completely cover the side and back walls of the home. The front of the house is left open to the air, usually facing the south in order to harvest the natural heat and light provided by the daily sun. Roof covers are normally added to such a home to complement the berm-like sheltering effect of the hillside, and houses constructed in the elevational style have shallow rectangular shapes that feature bedrooms and living spaces arranged linearly in the foreground so the sun can provide heat and light to all the important rooms of the house. Elevational homes are the least expensive type of earth-sheltered structure to construct, and with their hillside locations they frequently offer grand panoramic views of surrounding natural vistas.




Building process

Now let consider the whole ideai that if you place a house underground it is  essential for it to be insulated and water proof.

All the new prefab builders etc are speaking about concreate ! But what about back in the 70’s  from the original guy who wrote the book !!! ?

Here is some of his qoutes about the subject matter in his book:

PSP stands for Post/Shoring/Polyethylene. These are the materials and the system which we use for building our undergrounds in Northern Idaho and, increasingly, throughout the west. Because the materials are different from those used by underground architects in the east we think of our methods as the Western School of Underground Architecture. The easterners use concrete as a basic building material. (We fondly think of the easterners as Concrete Terrorists.) The easterners use concrete because the resultant buildings will last for centuries avoiding disruption of the flora and fauna on the roof. Some like concrete because the roofs can withstand a greater load. They want to build places that can withstand the weight of trees. We can’t argue with these thoughts. It is certainly desirable to leave the vegetation on the roof undisturbed for centuries. And it is a testament to the degree of environmental concern of underground architects that they should insist upon roof soil conditions which allow the true natural environment and native trees to reassert themselves. However . . .
(1) Cement is a non-renewable resource. (2) Cement is rarely native to the building site. Being very heavy it takes great amounts of energy to transport. (3) Concrete is too permanent. To knock out a wall or punch through a new window or work on the pipes beneath a slab floor one must rent a jack hammer or hire a crew at great expense.

(4) Concrete is lousy to look at. It has no soul. (5) Concrete is expensive. Labor costs are high. There is more work (and material) involved in just building the forms for a pour than there is in building an entire wall by the PSP system. (6) Concrete is a poor insulator. One inch of lumber is a better insulator than six inches of concrete. In many cases then concrete necessitates the additional expense of insulation. (7) Concrete is difficult for the ownerbuilder to work with.
Wood is the basic component of the PSP system. Wood is fantastic stuff. Pound for pound it is stronger than steel. It is a renewable resource. It is abundant and can be found on many building sites. It is easily worked and can be milled on the site by the builder with a chainsaw and Alaskan Mill. Wood has warmth, richness and soul. It even smells good. In the PSP system treated posts are set into the ground after the excavation has been made. Beams for the roof are notched into these. Then a sheet of polyethylene is stretched around the outside of the wall. Shoring is placed between the posts and the polyethylene, one board at a time. The polyethylene is stretched snug, and earth is back-filled behind, pressing the polyethylene against the shoring and the shoring against the posts.
We believe the PSP system is a real breakthrough. Less than half the materials are used than in, say, the construction of a frame house. While wood is the basic component of the PSP system, polyethylene is the secret of its success. Polyethylene is inexpensive, easy to work with, and readily available. It is an absolute moisture barrier and is what keeps the wooden walls from rotting. While it is true that this plastic deteriorates quickly when exposed to the ultraviolet rays of sunlight, it lasts indefinitely underground. (Environmentalists are concerned that garbage buried in polyethylene bags may not decompose for centuries because it never becomes exposed to the dampness of the earth.) Being new to mankind this material has allowed us to develop a building system which is equally new.
Though polyethylene is an absolute moisture

And by the way are you askin if his house is still standing in 2017 from the 70’s

well yes it is !!! And he is extending even at his age and it has been great for his arthritis !
