House solely on AAV's?
My house design is that all SVP's are on AAV's and not vented to the external.
I met with my Architect today on site, and he wasn't sure if building control may ask for a vent.
Can anyone clarify (with references) that a house foul system can be vented purely by AAV's and don't need external vents.
Someone already has.

Reading the above study it looks like I was dramatic with my language. Just accept 20w extra heat load per soil stack or add 50mm mineral wool and forget all about it.
Yes but it's better to avoid holes in the roof IMO.
