HOME Ventilation
Guide
Ventilating
Living Areas
Bathrooms, kitchens and other
rooms have individual needs
for ventilation.
Proper ventilation of a home’s interior living area
requires two complementary strategies:
1. Applying local, or “intermittent,” ventilation in
areas with short periods of poor air quality such
as bathrooms, kitchens and other rooms using
fans that exhaust polluted air to the outdoors.
This limits the spread of contaminants to other
areas of the home. Sometimes, it’s necessary to
combine local ventilation with intakes that provide
outside makeup air.
2. Applying whole-house continuous ventilation
for the entire living area using quiet fans or heat
or energy recovery ventilators that constantly
work to expel stale air and bring in fresh, outside
air.
Let’s start with the first strategy, applying intermittent,
local ventilation.
