Betreff: [EnergyPlus_Support] window blind
I am interesting in modelling exterior blinds with 1m (width) but i am
experienced some problems.the EP manual says that , for field slat
width,
the maximum value is 1 and , for field Blind-to-glass distance, the
maximum
value is 0.3.If I not mistaken the maximum value for the blind-to-glass
shouldn´t be more than half of the slat width?In this case how can i
model
my 1m exterior blinds?
This is my first time with window blinds, could anyone send me a simple
example file containing blinds to my study.
Best regards
Lourenço
