isolated for 18 hours and the other you won't.

I'd "close it off" automatically by closing a motorized damper or
turning off a fan in series with a heating thermostat in the living
space in series with a cooling thermostat in the sunspace.


They might gain 0.6x490 = 294 and lose 6h(70-26)1ft^2x0.35 = 92 Btu/day
for a net gain of 202 Btu/ft^2 on a Kalispell sunspace. On a 24-hour
living space, they would lose 24h(65-17.9)1ft^2x0.35 - 294 = 102 Btu/ft^2
on an average December day.
