This is what I pose to you all now:
Equations or not, logic or not, denial or not, common sense or not -
wouldn't it be easier to find out about heat loss or gain through
skylights by doing an infrared image / taking an infra-red picture?

Thoughts?


If you actually care, then the sensible thing to do would be to
equip the damn skylights with insulated covers that you close
at night, or which close themselves.
