Before you give up on the green roof model you might want to contact Dr Saylor, the developer of the green roof model to find out if he can help you figure out what was wrong with your green roof model. >http://web.cecs.pdx.edu/~sailor/Contact.html
He is a nice guy, and typically willing to answer questions about his works.

Dear Group,
Is it feasable to include a HAMT set up as an alternative for the greenroof material? My concern is that the HAMT object will take relative humidity into account, but not rain or irrigation as such.
Correct?
Jean.
