Hi Rina,
Have you activated the roof irrigation. I had the same problem
and the main cause was the lack of irrigation. Try it and I hope I managed to
help you

Subject: [EnergyPlus_Support] Green roof simulation
Hello.
I am currently simulating a building with a green roof and comparing its energy
consumption to that same building but without a green roof. I am running into
problems that the energy consumption for the building with the green roof is
higher than the energy consumption for the building without the green roof. I
have not been able to figure out why. I think it might have to do with my HVAC
fields. I am simulating using a window air conditioner. Has anyone run into a
similar problem or does anyone have ideas of where I could have gone wrong?
Thank you.
Rina
