The curtain is in the lowered position in wintertime nighttime and during summertime daytime. The curtain was invented and patented in 1980 by the late Ron Shore, a teacher at the Colorado Rocky Mountain School (Solar Applications Laboratory) in Carbondale, Colorado (see: http://www.builditsolar.com/Experimental/HighRShades/shadesf.pdf)
