1. What is the primary purpose of installing insulation in a building
envelope?
a. To increase air leakage
b. To eliminate the need for ventilation
c. To reduce heat transfer through the building envelope
d. To increase indoor humidity
Rationale: Insulation reduces conductive heat transfer between
conditioned and unconditioned spaces. Proper insulation helps
maintain indoor temperatures, reduces heating and cooling loads, and
can improve occupant comfort.
2. Which type of heat transfer occurs when heat moves through a
solid material such as a wall stud or window frame?
,a. Radiation
b. Convection
c. Evaporation
d. Conduction
Rationale: Conduction is the transfer of heat through a material due
to molecular interaction. In buildings, heat can conduct through
framing members, insulation, glass, doors, floors, and other solid
components.
3. What is the main purpose of air sealing in an energy-efficient
building?
a. Increase uncontrolled ventilation
b. Increase indoor humidity
c. Reduce unwanted air leakage
d. Increase conductive heat transfer
Rationale: Air sealing closes unintended openings in the building
envelope. Reducing uncontrolled infiltration and exfiltration can lower
heating and cooling loads while improving comfort and reducing
drafts.
4. Which location is commonly inspected for air leakage during an
energy-efficiency installation?
,a. Interior furniture
b. Finished flooring only
c. Penetrations around pipes, wires, ducts, and other openings
d. Cabinet hardware
Rationale: Utility penetrations are frequent sources of air leakage.
Proper sealing around pipes, electrical wiring, ducts, and other
penetrations helps create a more continuous air barrier.
5. What does an R-value indicate?
a. Electrical resistance
b. Moisture content
c. Resistance to heat flow
d. Airflow rate
Rationale: R-value measures thermal resistance. Higher R-values
generally indicate greater resistance to heat flow, although actual
building performance also depends on installation quality, thermal
bridging, air leakage, and moisture conditions.
6. What happens to heat loss through an insulated assembly when
its effective thermal resistance increases?
a. Heat loss always increases
b. Heat loss remains unchanged
, c. Heat loss generally decreases
d. Moisture production increases
Rationale: For a given temperature difference, increasing thermal
resistance reduces conductive heat flow. This is one of the
fundamental principles behind insulation upgrades.
7. Which condition most directly reduces the effectiveness of batt
insulation?
a. Correctly fitting the insulation
b. Installing insulation continuously
c. Compression, gaps, or voids in the insulation
d. Properly supporting the insulation
Rationale: Batt insulation performs best when installed according to
its intended thickness and coverage. Gaps, compression, and poorly
fitted sections create areas of increased heat transfer.
8. Why is thermal bridging important in energy-efficient
construction?
a. It increases insulation R-value
b. It prevents all condensation
c. It creates localized paths for increased heat transfer
d. It eliminates air leakage
