Hi all,

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.

I tried something along the lines of this for the window in *.inp, but
without success:

SWITCH-CONTROL = ({if (#G("DRY-BULB TEMP")>60)
GLASS-TYPE-SW = "ECW-switched"
then "DIR-SOL-INC"
else "NO-SWITCH"
endif})
SWITCH-SET-LO = 15.9
SWITCH-SET-HI = 15.9

Thanks in advance,

Adam
