ERV for a basement apartment
We are renovating a 900 sq. foot basement apartment in Beacon, NY (Hudson Valley – area code 12508). It’s partly below grade, and pretty tight with new double pane windows.
We’re thinking of putting in an ERV for ventilation since:
1) We think that having the availability of ventilation in the basement apartment is a good thing.
2) We’ve noticed a slight mustiness in there.
We just got the house and need to do the reno pretty quickly, so can’t take things like RH across multiple seasons. We could test for air tightness, but it seems pretty tight upon inspection by our contractor.
We’re leaning toward the ERV because:
1) There will be some energy savings (though from what I’ve read not a very big amount)
2) It seems to give a more conditioned air coming in than plain ventilation (e.g. somewhat warmer air in winter and cooler in summer than with straight ventilation).
We’ll probably add some dehumidification with a portable unit if it turns out to be needed (the previous occupants said they did that in the summer, and that was all they needed – no AC). We may be able to hook it up to a drain to eliminate the need to empty the unit.
Any thoughts on the above?
How would the above compare to having a ventilating dehumidifier? I’m concerned that would bring in cold air in winter, hot air in summer when ventilating.
Pros/cons of each approach?
Thanks very much in advance,
