The kitchen is many times considered the heart of the home. It also provides an excellent ventilation opportunity. New codes have gone into effect across the country (known as ASHRAE 62.2) that require a centralized exhaust fan providing continuous ventilation.
Builders have a few options for how to
solve for this. Many are installing a separate exhaust fan in the main living
areas. They are typically very quiet and can barely be heard when running. This
is a good solution as it meets the requirements and is usually not even noticed
by the occupants of the home. The negative is that it is an additional item
that needs to be installed and maintained within the home.
A second option is a
dual speed fan installed in the bathroom. This is the “two birds with one stone” theory. These fans
have a very quiet low speed that runs continuously to meet the requirements of
ASHRAE 62.2 but also have a high speed – sometimes called boost speed that
kicks in when the room is in use. They can be controlled by humidity sensors,
motion sensors or just by a standard switch. While these work, the challenge is
that typically bathrooms are not located in a “central location”. Basically the minute you shut the bathroom door, you have cut off the
airflow from the rest of the home. The purpose of ASHRAE 62.2 is to provide air
exchanges within your home, brining fresh air in and exhausting stale air out.
There is another solution however – a multiple speed range hood. Much like the
two speed exhaust fan, these range hoods have an almost silent continuous speed
that meets the ASHRAE 62.2 requirements. When the range is in use, the hood can
be turned to an appropriate speed to provide the additional ventilation needed
during cooking. As with two speed exhaust fans, using a range hood has the two
for one benefit, there is no need to install a separate fan. The added benefit
of using a range hood is that in many homes the kitchen is located in a
centralized location or at least in a location that is not cut off from the
rest of the home.
