Allison:
Not sure if this will fill your requirements.
Look up CONDUCT-TMIN-SCH in the DOE-2.2 manuals. It appears you can
switch U-values on windows, but by outside air temp, not time.
But check this.

Subject: [Bldg-sim] night shading
Any advice on creating night shading? The specification calls for
increasing the R value of the window from 2.5 to 7.7 for night blinds.
I created a conductance schedule with fraction values. My intention is
to increase the window R value by 100% to make it as close as possible
to 7.7 (2.5 to 5) and the max the fraction schedule allows. I have not
used this before.
Thanks
