[Equest-users] U value for green roof

[Dayani Nayantha]

Bill,

Thank you very much for your answer.

All,

I'm trying to model a green wall in my design. I thought of introducing a
material by properties. And i'm thinking of having conductivity = 0 and
specific heat = specific heat of water. But i have no idea what i value
should put for density. Or i can introduce a material by U - value. But
again I couldn't find the u - value of the grass. So please can anyone help
me on this?

Best Regards

Dayani
