what is the sky view factor for an isolated building? 0? I am using energyplus. But I think the view factor doesn't depend on the tool. Right?

@llfan_123 what do you mean by "isolated building" (no surrounding buildings, e.g.) Also, what simulation tool are you using? Please mention the tool in the title or body of your post, as well as add a tag for the tool so that others can provide better help.

Please check. Edited.

@llfan_123 thank you for the edit. What do you mean by "isolated building"? Only one building in the entire model?

I used the baseline model in energy plus. It is for isolated buildings with one building in the entire model.

My past post might be helpful.

image description

Each external surface has its own sky view factor (Fsky). φ is the tilt angle of the surface. For vertical wall, cosφ=0, and Fsky≈0.354. For horizontal roof, cosφ=1, and Fsky=1.

The relevant part of Engineering Reference is here.
