How To Use An "Artificial Cave" To Eliminate Cooling Costs

"Artificial Cave" Can Keep You Cool Year-Round

While the principles behind this have been know for thousands of years, few have actually used it for their personal benefit.  Those who have installed it are amazed how well it works for their home. The reasons for using this method are:

  • Reduced cost (free in many cases)
  • Less harm to the environment
  • Conservation of other natural resources.

How Does It Work?

The system is based on the premise that we all know that a natural cave anywhere basically is kept at a pretty unvarying temperature by Mother Nature herself. Nearly all climates make said natural cave much cooler throughout the year, but it’s even cooler in summertime, including in the middle of a hot day.

Using the previous thoughts just mentioned this revolutionary system creates an “artificial cave” underneath most homes in order to take advantage of what Mother Nature has wrought. Specialized engineering calculations have been used in order to keep this “artificial cave” small and yes, even inexpensive.     

What is Cave Meteorology?

Using cave meteorology one learns that the geothermal gradient, meaning the rate of changes in temperature associated with depth, changes the deeper toward the earth’s core one goes. This is because the earth’s core is very hot.  Based on this, the “artificial cave” has not been located very deeply. 
Because the sun drives weather, the cave does not have the sun’s rays to warm it.  Meanwhile on the outside of the cave, temperature differences then lead to pressure differences. This in turn leads to precipitation and of course wind.

Why Doesn't Weather Affect This?

Doing away with all those factors not only allows for warming of the cave via rock formations that are warmed by the sun, and let’s assume that we’ve gotten rid of incoming wind and any water that might penetrate our cave has also been sealed off. 
The actual change of temperature in most caves is about 1 degree from night to day and day to nighttime attributable to this warming from the sun. We now can see the wisdom of the “artificial cave” for cooling our homes.

But Will It Work For Me?

To know if this will work for you, you really only need to look at one thing, and that’s the average temperature in your corner of the world. Whatever that average temperature is recorded at, is the temperature that your “artificial cave” should be able to maintain. 
Put simply, blowing warm air through the cave should allow the cave to return cooler air to you, right?
Also because the “cave” only has 40% humidity, that’s the humidity factor that should be blown into your home. Thus, the only cost after the initial investment to build the “cave” is the electricity needed to conduct air from one locale to another.

Scientific Research

Currently there is in-depth research being conducted regarding better understanding of cave meteorology.  The scientific results are going to help tremendously when we study heat exchange between the surface vs. the subsurface air in order to figure out the amount of influence it has on cave ecosystems.
