[EnergyPlus_Support] Re: g-value vs. SHGC

["kk080769" <kk080769@xxxxxxxxx>]

Tank you Mahabir and Edward, I already got the simulation manual of 
WINDOW5 and now (thank you Mahabir) I got the NFRC200 too. BUT...the 
simulation manual and the NRFC say nothing about the calculation 
procedure of the SHGC of the glazing they just describe the boundary 
conditions (outside/inside temperature, wind) for the calculation 
with the procedure according to ISO 15099...which means I still like 
to have the description of the calculation procedure of the ISO 
15099. Probably any University skripts available at the WWW which 
covers the ISO...? Couldn´t find anything until now, and if I buy it 
from the ISO company the price is ca. 140 euro..to much for a poor 
student:-)
Thankful for every help or idea,
Konstantin
