Under window properties, there is a tab called: "Blinds - Slats -
Drapes". Here is what eQuest says:<br>
<br>
If the heat gain transmitted through the window from direct solar
radiation (with the shades and blinds not covering the glazing) exceeds
the Maximum Solar Schedule threshold value, the shading device covers
the window (and DOE-2 uses the Shading Schedule to calculate the solar
transmittance of the window and shade). Both the Shading Schedule and
the Conductance Schedule will only be used when the direct solar gain
is greater than the Maximum Solar Schedule threshold value.<br>
<br>
Specify a "Maximum Solar Schedule", then specify a corresponding
"Shading Schedule" for the window.<br>
<br>
Is this what you were looking for? Hope this helps,<br>

everyone:<br>
I am now encountered a problem in modeling an automatic pull down
exterior shades of a window, and am seeking your help. The radiation
responsive exterior shade will be triggered when the radiation arrives
on the exterior surface of the window pane exceeds a certain amount
(say 30btu/ft2hr). Since there is a relatively good insulation
properties of the exterior shade (say U-value=
1.1 W/m2h), I would like to let DOE2 to take the insulation effect of
the shades when it is deployed into consideration. Do you have any
suggestions on how to model this?</span></p>
