- They offer passive, energy-efficient ventilation. One interesting fact about whirlybirds is that they can be used to ventilate buildings in a passive, energy-efficient way.
- But, they need a lot of wind. If the vents don’t spin, the ventilation system doesn’t work. Australia does not offer the windiest of climates. Therefore, on those still, hot, sticky summer days, a whirlybird may not offer the relief a residential home requires.
