Honeybee green roofs and walls

I want to test the exterior thermal comfort by testing different scenarios using (honeybee 1.6):

  1. The room has 1 green wall
  2. The room has 1 Green wall and a green roof
  3. The room has 1 Green wall, a green roof, and is surrounded by green ground.

I keep getting the same error when I connect the green roof and/or the green ground to the model. What should I do to fix this issue? also, is this the right way to test green roofs and walls, or there is a better way?

What does the HB Validate Model tell you about your Model that you’re trying to simulate?

The report showed that the model is invalid since I’m using two types of greenery. Is there a way to make it work?
