Ventilation Advise % Articles
Based on the 2010 ASHRAE standard 62.2, all residential homes require
ventilation. This ventilation can come from openings in the building
shell (doors, windows), air infiltration through the building shell, or
by mechanical ventilation such as exhaust fans, supply fans, Energy
Recovery ventilators (ERV), or heat recovery ventilators (HRV). Based on
the 2010 version of ASHRAE Standard 62.2 (currently above Omaha
residential building code), all bathrooms and kitchens should have
exhaust fans vented to the exterior of the house (not the attic space).
Bringing in air from a clean outdoor location and removing polluted
indoor air from kitchens, bathrooms and other locations may still be
important in order to improve air quality. If air sealing work is
undertaken, the air leakage rate must be re-measured to determine
ventilation requirements.
Below are some excellent articles, websites, etc. with lots of information on sealing air leaks in existing homes.
