Infiltration Testing of Homes in the Houston Gulf Coast Area
Abstract
Air Changes per Hour (ACH)
are determined by construction
and weather conditions. In this
test, it was found that the ACH
is equal to .59 plus .07 for
every year of age the home has.
The higher ACH values for age are
due to deterioration and
construction techniques.
The American Society of
Heating, Refrigeration, and Air
Conditioning Engineers (ASHRAE)
has a methodology for determining'
ACH based on component leakage
areas. The results found using
this method are close to the
results found in testing new home
construction. Weatherization and
retrofitting can decrease the ACH
in an older home, however, a
significant decrease would
generally require significant
retrofitting and expense.
