I think the largest two over the pool area are 600mm. They also don’t ventilate the roof cavity, they ventilate the actual rooms of the house. Hence most are placed over the raked ceilings as that’s where the heat will rise to, and be purged through the vents. They can be used passively but also actively. So no eaves vents required in this instance. I suppose with your situation you’ll have to look at the volume of air the whirly bird is able to extract and match it with sufficient air entering the space, be it weep holes or eave vents. The closable ceiling vent sounds like a good idea if you want to remove excess rising heat from rooms directly (which is what we’re doing!). Have you spoken to professionals? In our research we discussed with two or three companies and found that quite helpful. They looked at the house plans and elevations and made suggestions, including where to place the input and output vents. Our biggest concern was to ventilate the pool area, hence this type of ventilator.

I wondered why you had so many vents in very specific spots. Raked ceilings would work very well for this as you say. Would you think this system would still be effective in a house with a typical flat ceiling? Without knowing your roof section thickness....what type & approx. length of duct connects the roof vent to the ceiling outlet? A few months ago I was investigating 'whole of house fans'. They are fairly large diameter and sits over your ceiling an purely suck heaps of air into the roof area. Obviously not a passive system, but they run on a fairly efficient DC motors. With our roof ventilators and potential eave vents (to expel the air) I'm still considering this single large fan option. --------------------------------------------------------------------- Check our Homeone build blog here Re: Custom build Sydney Hills with attached granny flat 129Jun 28, 2019 1:28 pm darb74, our rumpus area has a flat ceiling and there will be a vent there. I don’t think it says anywhere that it’s for raked ceilings only, so I can’t see why not. The raked ceilings don’t have much distance between the roof and ceiling, it’s literally just the roof frame thickness I think. The flat ceiling has more, but I haven’t seen the duct as that section has no roof yet even! I’ll try to get a photo for you when that goes up. I’m thinking the length is as long as it needs to be!

Carpenters have strengthened the joists and added yellow tongue flooring. The ceilings and walls will not be finished, and there will be a good quality pull down attic ladder to get up there through our WIL. In the future we could make it into a proper living space by covering walls and ceiling and adding skylights, windows and a proper staircase. Its’s not really in our plans though, unless life circumstances change dramatically. For now, the electrician will run lighting up there and a couple of data cables. This photo was taken by me just climbing up the temporary ladder and sticking my head through the hole in the floor.

There are no ducts between the roof ventilators and the indoor vents. With flat ceilings the ventilators DO suck the air out of the roof cavity as well as the rooms of the house, the latter through vents placed in ceilings. When the ventilator is placed above a raked ceiling though I’m not sure if it goes directly through to the ceiling or if there’s still separation between roof ventilator and ceiling vent. I can’t imagine there’s much space to ventilate there anyway. Re: Hamptons inspired architect design with attached granny 137Jul 16, 2019 3:56 pm Awesome build, subbed! Hamptons inspired architect design with attached granny flat 138Jul 25, 2019 2:14 pm The lower roof is now complete. It’s been great to be able to get a better feel of our main living space. Standing in kitchen looking through dining and living area. Nice midday winter sun coming in. The spotty shadow is scaffolding. Morning sun comes in through the end gable window. Loving the raked ceiling!
