Experimental / Prototype architecture 

I suggest that any specific designs which have not had formal evaluation should not be included as part of this article.  A casual reader may be mislead into believing that they would be able to reproduce these results.

see http://www.fsec.ucf.edu/en/research/buildings/zero_energy/lakeland/index.htm for an example of a very strict protocol for evaluation.

These examples may need further validation:

John Hait's "Passive Annual Heat Storage" (PAHS) method 
Water walls and roof ponds
Australian deep-cover earthed-roof
Don Stephens' "Annualized Geo-Solar" (AGS) heating
Thermal Buffer Zone / zero Energy building
