Continuous mechanical ventilation for dwelling units?
Continuous mechanical ventilation for dwelling units?
(OP)
Is continuous mechanical ventilation required for dwelling units?
In another thread, the conclusion seems to be that it is impossible to rely on natural ventilation for a dwelling unit and still meet both the 2012 IMC and the 2012 IECC.
ASHRAE 62 has a procedure for calculating the outside air requirements for intermittent ventialation, though the cooling coil in a residential heat pump might not accommodate the resulting percentage of outside air.
I don't find mention of intermittent ventilation in the 2012 IMC. Rather, it says:

"Ventilation shall be provided during the periods that the room or space is occupied."
If a dwelling unit is always occupied, it would seem to need continuous mechanical ventilation.
It doesn't seem very "green" to require the furnace fan in a residence to run continuously.
