I don’t disagree with anything you say Henno, but there is a wider picture than the aspirations of people who seem to centre on thermal efficiency and sealing.
People I have spoken to have agreed that the sealing standard is pointlessly high may be leading us to serious ill bronchial ill health.
Sensationalist as this sounds it is clear that we have assimilated aspects of commercial design with none of the safeguards.
MVHR is a cut down version of full air conditioning but with none of the fire prevention measures.
In addition the hazard is higher in the house which has potentially a 100% sleeping occupancy.
This is greater than even a hospital or nursing home where there are alert staff on call.
Branching ducts can allow for the regulated transfer of old smoke and fumes transfer.
Ducts containing water and deposits can be a breeding ground for bacteria.
This can create conditions for legionella to grow outside of the hot tub.
I don’t think we’ve thought this all through for Irish conditions.
