My shop has no wall windows. I have 2 insulated 12'x12' overhead doors, each having 3 windows. I also have a man door with a window. If I were to build another shop, I would do the same. Wall windows take up too much valuable space. The windows in the doors do not allow enough light to keep the O/H lights off, but when I'm working in the shop, the lights are on anyways.
My insulated shop stays at 70 degrees in the summer if I leave the doors closed, even though we get plenty of 80-90 degree days here in Ohio. In the winter, I can keep it heated to 70 degrees for less than $100 a month. And that's a 40'x60' shop with 14' ceilings and natural gas heat. If I had lots of windows it would cost more to heat, and would not stay as cool in the summer.
I personally do not miss the windows. If I want to see outside, I just go outside, or open the overhead doors.
