I have specified under Macro Flo rooflight openings, to be set to always off, non operable. When i go through vista and selected the rooflight surface its show that there is a considerable amount of Volume Flow in. I want the rooflight to act only as a glazing and a non operable window. Does anyone know why this occurs?

So many possibilities:

1. You might have a crack flow, i.e. this might be infiltration. This flow is related to the crack flow coefficient in the Macroflo template.

2. You might not have properly assigned the desired template to the opening in question.
