Question

If a window gets no sun, does closing the blindes save on air conditioning bill?

Answer 1

Marginally. With less light comes less heat. A programmable thermostat and caulking all the exterior wall penetrations would make much more of a difference in energy savings than pulling that blind.  

Answer 2

probably not!    i mean y would it!

Answer 3

yes because the heat goes through the glass, even if it looks like it gets no sun

Answer 4

Yes, heat outside travels through the glass; a blind decreases the heat transfer ratio.

I hope it helps.
