If your ever traveling across the country side you may have the occasion to see a home built into the side of a mountain or someone parked on top of their house, it may seem odd at first but the truth is these Earth Shelters are among the most energy efficient dwellings in the world.
There are many common misconceptions about Earth Shelters or Underground homes. One misconception being that the homes are dark and claustrophobic. The truth is that a well built home will have an open ended face which would has southern exposure. A dome style would have reflective walls which splash natural lighting to every part of the home. They often include skylights which supplements the the internal light and is referred to as co-linear.
Another misconception is that interior air quality is poor due to the lack of ventilation. The implementation of Air exchange systems will demystify this myth and in fact the quality of air is usually significantly better than that of a conventional building.
Many people also believe that an earth sheltered home is cold. If you’ve ever lived in a home with a basement, then you would know that it stays warmer in the winter and cooler in the summer. The earth acts as an insulator and maintains a mean temperature of 55 to 60 degrees year round. This geothermal property saves thousands of dollars as well as preserving an abundance of fossil fuels.
In addition to these advantages, earth shelters can be built into the side of a mountain or other landscapes that would otherwise be unbuildable which in turn preserves valuable farm land.

Other advantages include:

  1. Unparalleled structural integrity making them safe from hurricanes, tornadoes, hail, fire, earth quakes and other natural disasters
  2. Better land usage (you can park on the roof)
  3. A significant reduction in utilities and energy costs
  4. Energy savings and tax incentives
  5. Insect manifestation is a non issue due to impenetrable shell
  6. Thieves are less likely to target these homes because of the single open wall
  7. Pipes will not freeze
  8. Exterior maintenance is almost nonexistent

The disadvantages are few. These homes are nontraditional and must be planned with extreme caution. A leak due to inproper waterproofing can be a costly fix. Removing tens of tons of earth from the roof can add up to thousands. Another disadvantage may be resale value. Due to the unconventional style, buyer might tend to shy away. lastly, until these homes become a little more mainstream, the initial construction costs are slightly higher than that of a conventional style home.

The long term energy savings and tax incentives far outweigh that initial expense. With the implementation of Wind and Solar Power Generators and the incorporation of geothermal heating and cooling, it is probable that the owners of underground homes will live ‘Off The Grid’ never having to pay a utility bill again. These are true green homes and are the representitive of sustainability.
