To answer your questions let me put it this way. Many many years ago, as a kid, I remember being in Timpanogos cave where the Ranger told us the temperature stays at around 50-55 all year. The
PAHS(Passive Annual Heat Storage) and
AGS(Annualized Geo Solar) concept is that we create a cave designed to keep the greenhouse at 65-85 all year.
Yes, those automatic vents are awesome but may be unnecessary.
The adjustable louvers/blinds for control of visible light will be outside to control the amount of summer heat that enters the structure.
If solar panels are used, it will be for running water pumps to further reduce dependence on purchased electricity.
This last winter, I came to the realization that ground water in the cave may be counter productive to keeping the greenhouse at 65-85 degrees.
* I just had another epiphany.* Why can't the insulating umbrella be just lightly covered with a protective layer of dirt rather than 2 feet underground? What other changes could be made to this insulation umbrella which is meant to be a barrier to heat draining precipitation and moderator of seasonal temperature extremes?
It's time to revise the drawings.
Aloha
