Passive-solar has been known to work well but certain things about our architecture fail the thermodynamic efficiency test and there are reasons why.
First is heat-transfer through conduction, the wood, drywall, sheathing all having rather high heat-transfer coefficients. Next is convection from a heat-riser which takes the warmth of the floor and moves it to the ceiling.
Until these are dealt with they cost a lot of energy, if one is trying to not require external heating for…Continue
