PASSIVE ANNUAL HEAT STORAGE, IMPROVING THE DESIGN OF EARTH SHELT torrent

How can I build an earth sheltered home that saves summer heat for all-winter heating?

Use your home itself to collect free solar heat all summer.
Cool your home passively, while heating the earth around your home, without machinery or commercial energy.
Keep your home cozy all winter by retrieving heat from the soil.
Utilize the free solar heat stored throughout the summer as a year-round natural thermal resource.
Power a convection ventilation system using stored heat that provides warm air all winter and cool air all summer.

Passive Annual Heat Storage (PAHS) is a method of collecting heat in the summertime, by cooling the home naturally, storing it in the earth naturally, then returning that heat to the home in the winter. It includes extensive use of natural heat flow methods, and the arrangement of building materials to direct heat from wherever we get it to wherever we want it, all without using machinery to make it work. With the rising cost of energy, all home builders should get familiar with basic PAHS principles.

The goal of Passive Annual Heat Storage is to provide a method of placing building materials and organizing construction so that the comfortable environments produced are continuously pleasant. The resulting subterranean home interiors are balanced with the natural environment, and are able to extract all of their energy needs from their surroundings without using any commercial energy sources. Thus, there is no longer any need for using mechanical devices or causing any disruption in global ecosystems.
