Hello, everyone. I am using Designbuilder to simulate the impact of different types of window on cooling load of classroom in hot and humid area. But I got results which I could not understand. For example, I compared two types window, one is clear glass window, the other is low-e window. As the pictures show, There was a obvious difference in solar gains external window and of course Low-e window performed better. But the total cooling load of the space with low-e window was silghtly larger than the space with normal window. Does anyone knows the possible reason for this situation? Thank you.
