Hi, you may try to use EnergyPlus. Please find the details of it through following link:https://energyplus.net/

I think the answer is NO, you can use EnergyPlus or TRNSYS, though which are also not sufficient enough.

thanks everyone.

The environmental benefits of a green roof go beyond just the thermal benefits of adding a bit to the roof insulation. Green roofs also mitigate the summer heat island effect of the sun heating roofs, they retain storm water run off, they create some habitat for birds and insects. If you want to use an energy model to determine the thermal benefits of the added roof insulation, a new, fast, accessible  model  is the Matchbox energy model. Let me know if you don't have on-line access to it...

How can i use it sir? I cannot sign up in order to log in the website.

Go to  < https://matchboxenergy.com/code >, then  put in your own password, agree to the terms of service and validate your email. The code word you should use is “trial” which lasts for 32 days, but I can extend it if needed.

Also be aware that the thermal resistivity of a green roof includes that of the assembly plus that of the soil and vegetation, which will vary wth the soil type and depth, moisture level, type of vegetation, and any seasonal variation in the vegetation, so will be an estimate. I haven't done research on establishing thermal resistivity values for green roofs; should be some on-line papers which would help in estimating thermal resistivity per inch, or other thermal effects of green roofs ( mass, evapotranspiration etc).
