.13 ACH home performance test results...is that too tight for spot ventilation, kitchen fan and electric clothes dryer?
My new house was tested at 50 pascals and my reading was .13 ACH.
The auditor and I also played with the spot ventialtion fans, and his manometer, and we were able to reach -46 pascals with all house fans on and the electric clothes dryer on. My concern is with such a tight house, where does the air come from during spot ventilation and clothes drying?
I have a HRV which provides slightly postive pressure in low mode during normal use...but does not adjust for the extra load of spot ventilation - namely the kitchen fan.
Do I have to open up a window every time I turn on the bath fan or clothes dryer?
