Hello Marcus.
The fenestration supplier of a project gave us SHGC values from a simulation. We would like to know if it is acceptable for LEED simulation. The supplier states the following:
"Simulations ere run using LBNL Windows 7, Optics 6 and WIS software with version 29.0 of the International Glazing Database."
Thanks

That should be acceptable. Make sure that your modeling methodology is consistent with the Window 7 calculations. So if Window 7 calculated the overall assembly SHGC when you model the windows you would not model the frames separately since the Window 7 calculation determines an overall assembly value. As usual be sure to explain how the windows were modeled in your LEED documentation to avoid a very common review question.
