Why Wofati instead of Walapini?

Well, this is my first post and I'm super excited to be a part of this amazing community!

So my question is: Why a Wofati instead of a Walapini?  
The berming of the Wofati seems potentially problematic from a construction perspective, and while the insulative value of the earth berm could be beneficial, wouldn't having more solar radiation (as is achieved in the Walapini) be more beneficial?  I have sketched out some drawings for alternative variations on the Walapini, but I've intentionally avoided berming (except to increase the rear wall height and increase thermal storage).  The below image is not mine, but it shows a Walapini design really nicely.

Welcome to the forum, Signa!

To me, a Wofati structure is a log cabin built in the side of a hill.

My understanding of a Walipini is it is a structure used as a greenhouse.

Or are you asking why build a wofati greenhouse?

Yes, that's what I meant, but Wow, in my very first post I have proven just how bad it is to make assumptions -- I'd read on another website about "wofati greenhouses", and I just assumed that's what they always were.  When I saw the topic here I jumped in with my post -- but I see now that had I done a little more investigation, and a little less assuming, I'd have answered my own question and learned something about Wofati's all at the same time!!

Glad I could help.

Please ask lots of questions.

This is a really great forum with a lot of knowledgeable people.

Thanks so much!  I'm looking forward to getting involved in the conversations and seeing what others are doing on their permie journey.
