How many windows should one have?

Out of pure interest, I searched a little further and found a paper on light published by the U.S. Department of Energy (google "osti 1167562"), here is an excerpt and again a diagram from me showing which portion of light is lost through non-floor-to-ceiling windows. Height is therefore more important than depth. But please do not underestimate here that more light is lost through non-floor-to-ceiling windows due to reflection from the floor than shown, yet the gain from floor-to-ceiling windows is seemingly small, especially if you can alternatively go wider and higher.

P.S: Yes, I know, it might be nerdy and I am still not an expert on the matter (so please do not take the representation as truth, it is of course only approximate), but I still wanted to share this layman information if someone else is also thinking about it. I guess the programmer in me is coming through :) For me, it just confirmed that it is not a big loss for us not to go floor-to-ceiling.

I'm not going to like this now because I find encouraging the feeding of nerdy readers rather questionable despite otherwise commendable sharing of informational basics. If the foundation slab is wrong, all the acquired Hoëcker knowledge about some theoretical peanuts is useless.

That must be the programmer in me coming through

Oh, programmer ... then my explanations about the purpose of Clean Code in house planning actually shouldn’t have been necessary ;-)
