the amount of solar gain would depend on surface area of skylights and the amount of insulation in the house. with small skylights and thin insulation you would not gain a lot of temperature. but if your entire roof is made out of glass and it's something like quadruple pane glass filled with krypton gas and your other walls are a foot of insulation and your floor is painted black you would probably be able to hit 100+ degrees inside when it is freezing outside with nothing but sunlight as a heat source.

cooling passively would be more difficult but not impossible. for example in NYC area ( where i am ) deep ground well temperature is about 53F so with a vertical ground loop system you could tap into that 53F when it's 95F outside for some passive cooling ... if you covered your roof and walls with mirrors

it's all possible the question is only at which point does it become ridiculous ...

i'm just opposed to people who do NOTHING and then demand we build more nuclear reactors.

reminds me of a fat guy who was demanding that children are vaxxed for COVID beause he was in a risk group for dying from it ... yeah mate maybe YOU should put down the spoon, rather than making kids take the vax when they are at zero risk from COVID and YOU are.

anyway it is not our job to tell Klaus Schwab HOW to maintain our standard of living. our job is to MURDER anybody who tells us that our standard of living ( but not their standard of living ) should go down to save the planet.

let Klaus figure out what the right mix of green technologies should be. whether it is solar, wind or nuclear or coal - i don't really care.

i'm just opposed to people who LEGITIMIZE THE SCAM of "global warming" by proposing nuclear as "the solution"

solution TO WHAT ???
