Answers with Detailed Rationales |
Complete Exam Prep & Study Guide
1. A mechanical plan reviewer is evaluating a new commercial building with a
variable-air-volume (VAV) system. The plans show terminal reheat coils
serving several perimeter zones. What is the primary reason terminal
reheat may be provided in a VAV system?
A. To increase outdoor-air ventilation rates
B. To maintain humidity by reheating all return air
C. To prevent excessive cooling of zones requiring less sensible cooling
D. To eliminate the need for balancing
Answer: To prevent excessive cooling of zones requiring less sensible cooling
Rationale: Terminal reheat allows the central system to deliver conditioned air
while individual zones receive only the amount of sensible cooling required. The
reheat coil then raises the supply-air temperature as necessary to maintain the
zone setpoint.
, 2. A plans examiner notices that a mechanical room contains a fuel-fired
appliance but the submitted drawings do not identify combustion-air
openings. What should the reviewer determine first?
A. The color of the appliance
B. The appliance's combustion-air requirements and the applicable code
provisions
C. The manufacturer's warranty period
D. The thermostat voltage
Answer: The appliance's combustion-air requirements and the applicable code
provisions
Rationale: Fuel-burning appliances require adequate combustion and dilution
air unless they are specifically designed and installed using another approved
combustion-air method. Plans must demonstrate compliance with the
applicable requirements.
3. A duct system is shown passing through a rated fire barrier. The duct has no
fire damper or other identified protection. What is the principal plan-
review concern?
A. Duct velocity
B. Fan horsepower
C. Protection of the rated assembly from the duct penetration
D. Thermostat location
Answer: Protection of the rated assembly from the duct penetration
Rationale: Duct penetrations can compromise the fire-resistance rating of an
assembly. The plans examiner must verify that the penetration is protected by
the required approved damper, shaft, enclosure, or other permitted method.
4. A commercial kitchen exhaust hood is located above grease-producing
cooking equipment. Which issue is most important during mechanical plan
review?
,A. Whether the hood is painted stainless steel
B. Whether the exhaust system is designed for grease-laden vapors and
coordinated with makeup air
C. Whether the hood has a residential thermostat
D. Whether the kitchen has a return-air grille directly above the hood
Answer: Whether the exhaust system is designed for grease-laden vapors and
coordinated with makeup air
Rationale: Commercial cooking exhaust systems have specialized requirements
because grease-laden vapors create fire and sanitation hazards. Exhaust,
makeup air, clearances, fire suppression, and discharge arrangements must be
coordinated.
5. A mechanical schedule lists a rooftop unit with a cooling capacity
substantially greater than the calculated building load. What should the
plans examiner do?
A. Automatically approve the unit because larger equipment is always safer
B. Verify the load calculation and determine whether the equipment selection is
justified
C. Require a larger electrical service
D. Ignore the discrepancy
Answer: Verify the load calculation and determine whether the equipment
selection is justified
Rationale: Oversized equipment can cause poor humidity control, short cycling,
inefficient operation, and comfort problems. Equipment capacity should
generally be supported by the calculated loads and applicable efficiency
requirements.
6. A duct system is designed to pass through a fire-resistance-rated wall.
Which drawing information is most useful to the plans examiner?
A. Duct paint color
B. Damper type, rating, location, and installation details
, C. Manufacturer's logo
D. Thermostat brand
Answer: Damper type, rating, location, and installation details
Rationale: A plans examiner must be able to determine whether the penetration
protection matches the rating and construction of the assembly. Identification of
the damper and installation details is therefore critical.
7. A mechanical plan indicates that an outdoor-air intake is immediately
adjacent to an exhaust outlet. What is the principal concern?
A. Duct insulation color
B. Recirculation of contaminated or exhaust air into the building
C. Fan belt length
D. Diffuser appearance
Answer: Recirculation of contaminated or exhaust air into the building
Rationale: Outdoor-air intakes must be located to minimize entrainment of
exhaust, contaminants, vehicle emissions, and other undesirable air. Separation
requirements depend on the applicable code and system type.
8. A designer proposes using a ceiling return-air plenum above a suspended
ceiling. What should be verified?
A. That the ceiling tiles are decorative
B. That the plenum materials, construction, and environmental conditions comply
with applicable requirements
C. That all ceiling tiles are removable
D. That the return fan is oversized
Answer: That the plenum materials, construction, and environmental conditions
comply with applicable requirements
Rationale: Ceiling plenums used for air movement may be subject to restrictions
concerning materials, combustibility, wiring, piping, and contaminants. The
reviewer must evaluate the complete plenum arrangement.
