[EnergyPlus_Support] changing glass properties
I had to define a glass layer in order to put my blinds in front of
window. But as I do not want the glass to be considered in the
calculation(open window with blind)I changed the transmittance and
reflectance values to 0.99999 and 0.00001 in order. But it gives an
error like;
** Severe ** Solar transmittance + front solar reflectance not <
1.0 for material GLASS - CLEAR PLATE 1 / 4 IN
** Severe ** Solar transmittance + back solar reflectance not <
1.0 for material GLASS - CLEAR PLATE 1 / 4 IN
** Severe ** Visible transmittance + front visible reflectance
not < 1.0 for material GLASS - CLEAR PLATE 1 / 4 IN
** Severe ** Visible transmittance + back visible reflectance
not < 1.0 for material GLASS - CLEAR PLATE 1 / 4 IN
their sum is equal to 1 . So what is the error? I didn't
understand.I've attached my summary input file.
Thank you
