Oh yeah, lots of passive solar heat in here, Kent. I have to keep the blinds closed a lot of the time, or it will get too hot in here.
I bet!! It can get quite hot. One of the things that Booth did on the southern elevation is put in an overhang for the top floor and an 'eyebrow' (a built in sun block - like an 'overhang') for the bottom and it cuts out the summer sun which rides higher in the summer sky. So it's cool in the sunroom in the summer and I've seen it as high as 95 in the winter when the sun runs lower in the sky, when it was 0 out. Pretty amazing actually and the extra materials for the sun room was not that much vs. having actual solar panels on the roof, etc. The 'odd time' is in the Autumn mostly when the sun is beginning to move below the overhang and eyebrow protection and it's still hot out. Then we open the side porch door because we want to keep the solar aspect 'tempered' so to speak.
eta.... night Jerry.
It's a fun toy too. You can see foot prints and hand prints for minutes after. I've seen deer on the tree line at night - regular night vision won't pick them up too well when they're in the tree line unless they're on the move. This picks up their body heat. DW had her down vest on - totally cool with her head and legs glowing
