perhaps in theory when you only look at temperatures, but the reality is there's this one big fireball in the sky that heats everything up through its radiation as well, and super insulated zero energy homes are notorious for overheating in summer unless you take counter measures
so the "a good insulated house keeps the heat out". eh, to some degree. but you'll get cooked eventually no matter what. what was it again, 200W/m^2? on all your walls, especially windows
this house hasn't the best insulation but a very solid thermal inertia so a short heat or cold wave gets buffered by the house itself. it was 34Β° yesterday and it didn't go below 20 this night yet even upstairs it's still only 24Β° and downstairs significantly lower
