Here in my province we use what you call "efficient windows" large windows of glass distributed and celosia, we love natural light, as here heat predominates, these windows are very good, like your child at night you have a lot fear, here there are many legends and we are very superticiosos.
Undoubtedly, these old windows, no matter how many years go by, will continue to exist, we have seen that year after year they are imposed on architecture
excellent work as seimpre dear friend @englishtchrivy
I wish you a wonderful nights
