질문 # 67
An architect is designing a sub-surface drainage system that outfalls into a site retention pond. The recommended shape, size, and slope of the drainage lines need to be determined for primarily which of the following purposes?
정답:A
설명:
In subsurface drainage system design:
The shape, size, and slope of drainage lines are selected primarily to achieve a desired flow velocity that prevents sedimentation and clogging but does not cause erosion.
Minimizing or maximizing flow is not the goal; the system must convey the design flow efficiently.
Velocity must be balanced - too low leads to sediment build-up; too high causes pipe damage.

Which of the following is an advantage of using a glycol-cooled air conditioning unit for a computer room?
정답:A
설명:
Glycol-cooled air conditioning systems use a glycol-water mixture as a secondary coolant instead of plain water. Glycol has lower freezing point and better heat transfer properties in certain conditions.
Advantages include:
Longer piping runs without freezing risk, allowing the chiller or cooling unit to be located further away from the computer room, useful for flexible building layouts.
Glycol prevents freezing in cold climates or exposed pipes.
It does not inherently reduce heat exhausted or is necessarily more sustainable than water cooling.
Glycol is generally more expensive than water.
Therefore, the primary advantage is the ability to locate the cooling unit farther from the space being cooled.

질문 # 69
Which elevator type is the most appropriate choice for a 15-story high-rise residential condominium where speed and noise are considerations?
정답:B
설명:
For a 15-story high-rise where speed and noise matter, gearless traction elevators are the standard choice:
highest speeds, smoother/quiet operation, and efficiency for taller buildings. Hydraulic (holed or hole-less) are limited to low-rise (#2-6 stories) and are slower/noisier; geared traction is mid-rise with lower speeds and more noise than gearless.

질문 # 70
In winter conditions, when the outdoor air is below freezing and the indoor humidity is maintained at 40 percent relative humidity for 24 hours a day, ice forms on the exterior surface of the stone facing.
Which of the following elements is missing from the building wall section?
정답:C
설명:
With outdoor below freezing and indoor RH ~40% continuously, interior vapor will migrate outward. If a proper interior-side vapor barrier/retarder is missing, moisture moves through the wall and can condense and freeze at the cold exterior stone, forming visible ice. Insulation, air spaces, or rain screens help heat/moisture management, but the symptom (ice due to vapor diffusion) points specifically to the lack of an interior vapor barrier in a cold-climate assembly.

질문 # 71 
Refer to the exhibit.
An architect is designing a multipurpose room that will operate daycare services as well as exercise classes.
The multiple occupancies within the space utilize components of the same means of egress system.
What is the occupant load factor that should be used in calculating egress?
정답:C
설명:
Step-by-Step Reasoning
1. Identify the occupancies from the question:
* Day care services # Occupant load factor = 35 net (from table in the exhibit)
* Exercise classes # Occupant load factor = 50 gross (also from table in the exhibit, under "Exercise room")
2. Determine how to calculate the occupant load for multiple occupancies:
According to IBC 2018, Section 1004.1.2 (Areas without fixed seating) and NCARB PDD study materials:
When multiple occupancies share the same means of egress system, the occupant load for the whole space shall be the sum of the occupant loads of the various occupancies.
However, if the space is not divided and is used interchangeably (multipurpose), the most stringent occupant load factor is applied to the entire area.
3. Applying the code:
* The multipurpose room is used for both daycare and exercise.
* Since the same space is used for different functions at different times (not divided), the most restrictive occupant load factor (the smaller number) should be used.
* Smaller occupant load factor = 35 net (Day care) vs. 50 gross (Exercise room).
4. Why "net" vs. "gross" matters here:
* Net floor area excludes certain spaces like walls, corridors, mechanical rooms.
* Gross floor area includes the entire footprint.
* Even though "net" typically results in a smaller area, when calculating load factors, the smaller occupant load factor number results in a larger occupant load - making it more restrictive for egress.
5. Conclusion:
The correct occupant load factor to use for this multipurpose space = 35 net (Day care), as it results in the largest occupant load and is the most restrictive for egress design.
