Hi Katia:
Quite simply, you have window area greater than your wall area. If you were the person with the all glass walsl, you must insure that what ever wall area you have (say 20' wide by 10' high, or 200 sq.ft), your window area is less than that. This includes the frame.

Dear eQuest users,
I am obtaining the following error when I am simulating the envelope:
"walls have a negative area"
What's the origin of this problem? And how can I solve it?
Thank you for your help,
