Hi Abraham,
Depending on what you’re trying to measure - you might be able to get away with just modeling a normal glass material with the correct VLT. If you’re only looking at daylight penetration (sDA or similar metric) than this would work (not perfect but would give you a good idea of how much light will enter the space).
However, if you are interested in studying glare or would like to create a more realistic rendering, than you would have to use another material definition… likely a trans material or some sort of BSDF material definition. Honestly, this is a very tricky thing to get right so as mentioned earlier, I would definitely reach out to Saint Gobain for some guidance.
