Passive house standards don’t cut it. Reducing 90% doesn’t matter if many of those energy improvements also apply to cooling.
> Waste heat from lights
Use LEDs and this is irrelevant for a home.
> people is constantly offsetting the heating energy
Insignificant in the scheme of things. Humans can’t even keep themselves warm when holding still in 50F.
> it's also about solar radiation gain.
Do you realize how little sun cities in the north get during the winter? Conversely, solar electricity can conveniently capture plenty of electricity quite near the time it’s required in the South.
Peak air con time is when there is solar radiation. Peak heating time is in the dead of night.
