Considering health and safety, where might you air seal first? ✅the shared wall
between the home and attached garage
What is infiltration? ✅outdoor air entering home
What is exfiltration? ✅indoor air escaping from the home
What are the 3 forces with the most effect on a building? ✅heat, air, moisture
What does the term "house as a system" refer to? ✅the interaction of all components
of the complete system
What phrase is commonly used to describe a building material or part of an assembly
that allows heat energy to transmit more rapidly from one side of the assembly to the
other than most of the assembly? ✅thermal bridging
Heat transfer measurement for heating or cooling equipment sizing purposes is
expressed in what units? ✅Btu/h

system operation? ✅closest to the air handler
When concentrating air sealing in a heating-dominated climate where is the most cost-
effective area to seal? ✅attic plane
The blower door depressurization test is a diagnostic tool that measures what? ✅the
amount of air infiltration through a building pressure boundry
Pascals and "inches of water column" are units of measure of what? ✅air pressure

to the home? ✅air source heat pump
What is the intended function of a "vapor barrier" in residential construction? ✅to keep
warm air and water vapor from reaching cold surfaces where they can condense
What is the purpose of bituminous coatings or other "dampproofing" material applied to
the exterior of residential foundation walls? ✅to resist the capillary transfer of moisture
into the wall
