1. What is the primary purpose of a multifamily building energy assessment?
A. Determine the property's resale value
B. Identify energy-saving opportunities and building-performance issues
C. Establish tenant rental rates
D. Determine the building's insurance premium
Answer: Identify energy-saving opportunities and building-performance issues
Rationale: A multifamily energy assessment evaluates the interaction of the
building envelope, mechanical systems, appliances, lighting, and occupant
behavior to identify opportunities for improving energy performance, comfort,
health, and safety.
2. Which building characteristic most directly affects the amount of heating
and cooling energy required?
A. Interior paint color
B. Building envelope performance
C. Number of parking spaces
D. Landscaping design
Answer: Building envelope performance
,Rationale: The envelope controls heat, air, and moisture movement between
conditioned and unconditioned spaces. Poor insulation and air leakage can
substantially increase heating and cooling loads.
3. What is the primary function of insulation?
A. Stop all air movement
B. Reduce heat transfer
C. Increase ventilation
D. Remove combustion gases
Answer: Reduce heat transfer
Rationale: Insulation slows conductive heat transfer through walls, ceilings,
floors, and other building components. It does not by itself provide an air
barrier.
4. Which method is most appropriate for identifying significant air leakage in a
building?
A. Blower door testing
B. Paint inspection
C. Water pressure testing
D. Electrical continuity testing
Answer: Blower door testing
Rationale: A blower door creates a controlled pressure difference across the
building enclosure, allowing the analyst to quantify air leakage and locate
leakage pathways.
5. What does a blower door primarily measure?
A. Relative humidity
B. Building air leakage
C. Furnace efficiency
D. Water consumption
,Answer: Building air leakage
Rationale: Blower door testing measures the amount of air moving through
leaks in the building enclosure at a specified pressure difference.
6. What is the purpose of combustion safety testing?
A. Determine roof insulation thickness
B. Identify unsafe combustion conditions and carbon monoxide hazards
C. Measure electrical resistance
D. Determine appliance age
Answer: Identify unsafe combustion conditions and carbon monoxide hazards
Rationale: Combustion safety testing helps identify spillage, backdrafting,
excessive carbon monoxide, and other hazards associated with combustion
appliances.
7. Which gas is a major concern when combustion appliances operate
improperly?
A. Oxygen
B. Carbon dioxide
C. Carbon monoxide
D. Nitrogen
Answer: Carbon monoxide
Rationale: Carbon monoxide is a toxic, odorless gas produced by incomplete
combustion. Improper venting, insufficient combustion air, or appliance
problems can increase the risk.
8. What is the stack effect?
A. Air movement caused by temperature differences between inside and outside
B. Water movement through plumbing
C. Heat movement through electrical wiring
D. Air movement caused only by mechanical fans
, Answer: Air movement caused by temperature differences between inside and
outside
Rationale: Warm air tends to rise and escape through upper-level leakage while
replacement air enters lower areas. The reverse can occur during cooling
conditions.
9. In a tall multifamily building, where is stack-effect pressure often
strongest?
A. Near the neutral pressure level only
B. At the upper and lower portions of the building
C. Only inside individual apartments
D. Only around electrical panels
Answer: At the upper and lower portions of the building
Rationale: Stack effect creates pressure differences that generally increase with
vertical distance from the neutral pressure level, making upper and lower
portions especially important when evaluating leakage.
10.Which condition can increase the risk of moisture problems?
A. Excessive uncontrolled air leakage
B. Proper drainage
C. Adequate ventilation
D. Correctly installed flashing
Answer: Excessive uncontrolled air leakage
Rationale: Air leakage can transport moisture into building assemblies. If
moisture accumulates and cannot dry, it may contribute to condensation,
deterioration, or biological growth.
11.What is the primary purpose of mechanical ventilation?
A. Increase electrical consumption
B. Provide controlled outdoor air
