First of all, congratulations on the dedication of a fantastic faculty - very nice!
However, it's not just about windows per se, its that the room looks so dark, dreary, and dungeon like. Penn State's room has no windows but it is very bright. Some of the other new wrestling rooms (and football facilities) I've seen look brighter too, whether it's natural light or just brighter because of better lighting or better colors. Lighting and design of a space impacts performance and mood, research shows that. Is it a major issue....no. Is it still a fantastic facility? Yes! But lets not pretend they didn't miss the mark on the lighting in the room. We are not looking for windows to look out on the prairie, just light that elevates mood and performance
BTW, if light and color have no impact on mood or performance, why are the visiting teams locker rooms painted pink at the Hawkeye football stadium?
