[EnergyPlus_Support] SHGC: Window 5 X EnergyPlus



Hi,

A question about the SHGC calculation made by Window5
and EnergyPlus:

I have mounted a "glazing system" on Window5 software,
that reported a SHGC equal to 0.166 ("Total Window
Results").
But when I use this construction in the EnergyPlus
(object CONSTRUCTION FROM WINDOW5 DATA FILE), the .eio
file reports a SHGC equal to 0.174.

These values should be the same or not? The SHGC
calculated by both software follows the same method,
or I am missing something... 

I have fallen in this question while doing a
simulation for LEED certification. My ECB model has to
have a window with SHGC limited to 0.17.

Any light on this topic will be appreciated :)

Thanks!
Fernando Westphal
