<div>Hi all,</div><div><br></div><div>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.</div>
<div><br></div><div>I tried something along the lines of this for the window in *.inp, but without success:</div><div><br></div><div><div> SWITCH-CONTROL = ({if (#G("DRY-BULB TEMP")>60)</div><div> GLASS-TYPE-SW = "ECW-switched"</div>
<div> then "DIR-SOL-INC"</div><div><span class="Apple-tab-span" style="white-space:pre"> </span>else "NO-SWITCH"</div><div><span class="Apple-tab-span" style="white-space:pre"> </span>endif})</div><div>
SWITCH-SET-LO = 15.9</div><div> SWITCH-SET-HI = 15.9</div></div><div><br></div><div>Thanks in advance,</div><div><br></div><div>Adam</div>
