I conduct energy simulation that has two types of green roof materials in a building using EnergyPlus.
LAI of a half of green roof area sets 1.0 and LAI of the extra area sets 3.0.
But this simulation has error as follow : GetSurfaceData: Only one EcoRoof Material is currently allowed for all constructions.
Please tell me how can I set-up simulation conditions if simulation with two types of green roof materials in a building is conducted.
Also, what simulation program should I use ?
