<div>E+ has some functions to control switchable glazings, for your case I would try the control "OnIfHighOutdoorTempAndHighSolarOnWindow", which seems to fit pretty well to your requirements.</div>

You might want to try this in energy plus<br>

<blockquote type="cite">I'm having difficulty implementing glazing that switches based on both direct solar incident and temperature. That is, I only want to allow switching when the outside dry bulb is over 60 F, and I want the switch to occur instantaneously
when the glazing receives 15.9 BTU/hft^2 direct solar incident radiation. I don't have experience with user expressions/if statements in eQUEST. I've been successful in implementing switchable glazing based only on temperature or only on direct solar incident,
but not on both.<br>
