Plumbing Systems
Environment: - CORRECT ANSWER- in this context, refers to managing the indoor
environment as the exterior environment is changing (keeping the interior temperature and
relative humidity within acceptable levels, and ensuring indoor air quality with an adequate
amount of fresh air and little to no pollutant concentrations
Importance of Occupants at a component of buildings - CORRECT ANSWER- Home
performance primarily deals with existing, occupied homes. Occupants are the beginning and
the end of the system: they may do things in a house that affect the other components, and
they are certainly on the receiving end when things like comfort and indoor air quality are
affected
Interacting relationship - CORRECT ANSWER- an action taken on one component causes
reactions or changes in other components, or worsens certain pre-exiting conditions (and
increases their likelihood of producing negative effects
Ice dams - CORRECT ANSWER- occurs when warm air melts snow on the roof directly
above, but does not melt snow on the overhangs. Water from the melted snow flows down
into the gutters, where it freezes. This prevents any further melting snow from draining
properly. Ice dams can damage the roof and everything beneath it.
Mechanical ventilation (bathroom fan) - CORRECT ANSWER- could cause air pressure
differences between the inside and outside of the home. If air leakage is present, this could
cause the house to leak air at a faster rate, which, in turn, would create the need for the
thermostat to be adjusted more often

Thermodynamics Definition - CORRECT ANSWER- an are of science that looks at the
relationship between heat and other kinds of energy
1st Law of Thermodynamics - CORRECT ANSWER- energy moves from place to place;
energy changes form one form to another; energy cannot be created or destroyed
Energy moves around and changes form.
2nd Law of Thermodynamics - CORRECT ANSWER- energy flows naturally from high
concentrations to low concentrations
HEAT moves from warmer to cooler; AIR moves from higher pressure to lower pressure;
MOISTURE moves from wetter to drier
Potential vs. Kinetic Energy - CORRECT ANSWER- Potential energy is stored energy. Think
of firewood, or a battery.
