Passive Annual Heat Storage

Passive Annual Heat Storage is a method of collecting heat in the summer-time, 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 so as to direct heat from where ever we get it to where ever we want it...without using machinery to make it work.

The result has been the creations of homes and other structures having a built-in temperature. That is, they are able to self-maintain an internal temperature that varies only a few degrees up and down from a comfortable average of about 70 (20 C.) Such homes have actually been able to produce a positive energy coeficient. That is, they collect and save more energy than they need for operation. Such homes have been built around the world and have been very sucessful from Montana to New Zealand, Europe to Alaska.

Naturaly, not all PAHS homes acieve this lofty goal. For it is more than just energy efficiency...more than just reducing energy costs. It's not just creating a ecologically-compatible and continuously comfortable environments for humans to enjoy. It is a goal that is above and beyond what most others in alternative energy field would dare consider as even possible.

The goal of Passive Annual Heat Storage is to provide a method of building materials placement, and construction organization such that the continuously comfortable environments produced are continuously pleasant, balanced with the natural environment, and able to extract all of their energy needs from the natural environment without using any commercial energy sources...without using any mechanical devices...without causing any disruption in the global ecosystems.

To date, a number of homes around the world have actually achieved full annual heat sotorage. That is, they collect absolutely every drop of heating and cooling energy that the homes need for throug long cold winters, long hot summers and the rest of the year too. They don't just reduce energy consumption...they provide a surplus of energy that is used to provide partial domestic water heating, and provide natural power to run fresh air, heat recovering, ventilation systems.

This information is being provided to promote the polipheration of PAHS structures, to promote energy conservation of a higher plain than is usually done, and to direct people toward the information needed to produce real and positive results.

With time, it is expected that the PAHS methods can be used to supply the home with all of its lighting and electrical needs also by extracting more of a surplus of natural energy from the environment. Not by the old ways of hydro and wind power...even though these have great value also. But by promoting and developing new ways to produce a home's needs in new... Passive Annual Heat Storage ways.

It is hoped that information here will be helpful for advancing the technology, helping each other to solve practical building problems, and provide access to publications, videos, plans etc. so that all may be brought up to speed on PAHS technology...that all may be benefited.
