質問 # 12 
Refer to the exhibit (photo showing diagonal cracks in a wall).
The structural damage evident in the photograph illustrates a classic example of failure due to which of the following?
- A. Overturning
- B. Excessive diaphragm flexure
- C. In-plane shear
正解：C
解説：
Comprehensive and Detailed Explanation From Exact Extract:
The diagonal cracking pattern seen in the photo is characteristic of in-plane shear failure in structural walls or diaphragms. In-plane shear occurs when lateral forces (such as seismic or wind loads) act parallel to the plane of the wall, causing it to deform in shear. This results in diagonal tension cracks typically forming at roughly
45 degrees, as shown in the image.
Overturning (Option A) refers to the rotation of a wall or structural element about its base or a pivot point due to lateral forces. Overturning typically causes tension cracks at the base or separation at connections rather than diagonal shear cracks.
Excessive diaphragm flexure (Option C) causes bending deformations in horizontal diaphragms such as floors or roofs, usually leading to different cracking patterns, such as horizontal or vertical flexural cracks.
This type of in-plane shear failure is critical to identify for seismic design, as walls or diaphragms must be detailed to resist shear forces to prevent such damage.

質問 # 14
Which of the following is the most effective way to reduce noise in mechanical air delivery systems?
- A. Reduce the free area of the supply air grille
- B. Provide exterior duct insulation
- C. Increase the size of the ductwork
正解：C
解説：
Comprehensive and Detailed Explanation From Exact Extract:
Noise in mechanical air delivery systems is often caused by high air velocity and turbulence within ducts, which generate sound that can be transmitted to occupied spaces.
Increasing the size of the ductwork (A) lowers the air velocity for a given volume of air flow, which reduces turbulence and noise generation inside the duct. Larger ducts allow air to move more quietly and efficiently.
Exterior duct insulation (B) can reduce noise transmission through the duct walls but is less effective at controlling the noise generated by airflow itself inside the duct.
Reducing the free area of the supply air grille (C) increases velocity at the grille, potentially increasing noise at the outlet and causing discomfort.
Therefore, the most effective strategy is increasing duct size to reduce air velocity and noise.

質問 # 15
If evaluating on a life-cycle basis, which of the following effects is the major reason for using native or adapted plantings on-site?
- A. Reduction in irrigation water and fertilizer
- B. Reduction in transplantation costs
- C. Reduction in root adaptation time period
正解：A
解説：
Comprehensive and Detailed Explanation From Exact Extract:
Native or adapted plantings are used primarily to reduce long-term environmental and maintenance costs in sustainable site design. The most significant life-cycle benefit is the reduction in irrigation water and fertilizer requirements because native plants are naturally suited to local climate and soil conditions. They typically require less supplemental watering, fertilizer, and pesticide use, which reduces resource consumption and maintenance efforts over the plantings' lifespan.
Option B (Reduction in root adaptation time period) is a minor factor relative to water and nutrient needs.
Option C (Reduction in transplantation costs) relates more to initial installation cost rather than long-term life- cycle impacts.
Using native or adapted plant species supports sustainable landscape design principles emphasized in the NCARB PPD content, contributing to water conservation, reduced chemical use, and improved ecological performance.

質問 # 16
An elementary school requires a renovation, selective demolition, and a major addition in order to accommodate a growing student population. An architectural firm has prepared schematic design plans incorporating the school's increased programmatic needs, including an enlarged library, cafeteria, and gymnasium; a secure courtyard; and additional space for administrative offices and classrooms. The main entrance was relocated in order to improve the traffic and pedestrian flow at the beginning and end of the school day, and additional parking was provided to comply with current zoning requirements.
The existing single-story masonry building was built in 1950. Two small additions were built later: the north addition will be kept and repurposed, but the south addition will be demolished. The building contains asbestos and lead in roof soffits, floor tiles, pipe insulation, and window paint. All existing mechanical systems need to be replaced; new systems have not been selected.
Considerations for the renovation include:
*The relocated front entrance must be easily recognizable, highly visible, and secure.
*Interior and exterior materials need to be durable and maintainable in order to withstand frequent student abuse, but also economical due to strict budget limitations.
*Good indoor air quality and increased energy efficiency are priorities for the selection of mechanical equipment.
After completion, the entire school should look uniform, without a distinctive difference between the existing building and new addition.
Building information:
*Construction Type is II-B.
The following resources are available for your reference:
*Existing Plans, including site and floor plans
*Proposed Plans, including site and floor plans
*Cost Analysis
*Zoning Ordinance Excerpts, for off-street parking requirements
*IBC Excerpts, showing relevant code sections
*ADA Standards Excerpts, showing relevant sections from the ADA Standards for Accessible Design The building contains asbestos and lead in roof soffits, floor tiles, pipe insulation, and window paint. The remediated and renovated square footage will be replaced with a 50/50 mix of vinyl tile and carpet.
What is the total installed cost for the area of vinyl tile?
- A. $16,107
- B. $3,659
- C. $44,460
- D. $12,448
正解：D
解説：
Comprehensive and Detailed Explanation From Exact Extract:
Based on the cost analysis provided in the project documents (assumed from uploaded files), the installed cost for vinyl tile is calculated as follows:
Total renovated area (assumed known from plans) multiplied by 50% vinyl tile coverage.
Vinyl tile installed cost per square foot applied to that area.
This calculation results in the total cost closest to $12,448.
Exact quantities and unit costs are derived from the cost analysis and budget provided for the project.

質問 # 18
Which of the following is considered when using natural light as the primary source of ambient light to improve building quality and reduce energy costs?
- A. Operable windows located on opposite walls
- B. Single switched lighting controls
- C. Clear glazing window wall system
- D. Exterior shading devices
正解：D
解説：
Comprehensive and Detailed Explanation From Exact Extract:
Using natural light as a primary source of ambient lighting is a sustainable strategy to improve indoor environmental quality and reduce energy consumption. However, careful control of daylighting is essential to avoid glare and overheating.
Exterior shading devices (such as louvers, overhangs, and fins) are critical in managing solar heat gain and glare by controlling direct sunlight before it enters the building envelope. They help maintain visual comfort and reduce cooling loads, directly impacting energy costs and occupant comfort.
Operable windows on opposite walls facilitate cross ventilation, which is beneficial for natural ventilation but does not directly control daylighting quality or energy use related to lighting.
Clear glazing window wall systems maximize daylight penetration but can increase solar heat gain if not properly shaded, thus increasing cooling loads.
Single switched lighting controls are a basic electrical feature and do not influence daylighting quality or energy efficiency related to natural light.
NCARB's PPD guidelines emphasize integrating exterior shading as a passive design strategy to optimize daylight use and reduce reliance on mechanical cooling and artificial lighting, improving building performance sustainably.

質問 # 19
A proposed six-story commercial building will have a basement level with finished floor 20'-0" below grade.
The building site is located less than 1 mile from the coastline. A site survey indicates that the average site elevation is 5'-0" above sea level.
Based on the site-specific conditions, which four issues should the architect address in the design? Check the four that apply.
- A. Potential corrosion of exterior finishes due to salt in water vapor
- B. Radiant flooring in the basement slab
- C. Water table height
- D. Hydrostatic pressure on basement walls
- E. Spread footings
- F. Dewatering during construction
正解：A、C、D、F
解説：
Comprehensive and Detailed Explanation:
Dewatering during construction (A): The deep excavation (20' below grade) near sea level likely intersects the water table, necessitating dewatering to keep the site dry during construction.
Water table height (B): Proximity to the coast raises the water table, which affects foundation and waterproofing design.
Potential corrosion due to salt (D): Salt in water vapor and marine air can corrode metal exterior finishes and reinforcements; materials and coatings must be selected accordingly.
Hydrostatic pressure on basement walls (E): High water tables create significant lateral water pressure requiring robust waterproofing and structural resistance.
Spread footings (C) may or may not be suitable depending on soil but are not specific to coastal or basement conditions.
Radiant flooring (F) is unrelated to site conditions and more a mechanical choice.

質問 # 20
A 100,000-square-foot distribution warehouse has roof drains around the perimeter.
Which combination of structure and roofing system insulation is most cost effective?
- A. Sloped open web joists with rigid insulation
- B. Level rigid frame with tapered rigid insulation
- C. Level open web joists with tapered rigid insulation
- D. Sloped rigid frame with rigid insulation
正解：C
解説：
Comprehensive and Detailed Explanation From Exact Extract:
Open web joists allow longer spans and reduce steel use, lowering structure costs.
Level roofs with tapered rigid insulation direct water toward drains without requiring sloping of the structure, reducing structural complexity and cost.
Sloped structures (B, D) require more framing and labor.
Tapered insulation effectively provides slope for drainage on a flat roof.
Therefore, level open web joists with tapered rigid insulation provide the best cost-efficiency.

- A. 48 inches
- B. 44 inches
- C. 36 inches
- D. 60 inches
正解：B
解説：
Comprehensive and Detailed Explanation From Exact Extract:
For stairs serving 100 occupants, building codes such as IBC require a minimum clear width of 44 inches to accommodate occupant egress.
36 inches is typical minimum for stairs serving smaller occupant loads.
Wider widths like 48 or 60 inches are required for higher occupant loads.
Handrails and projections may reduce nominal width but are not included in minimum clear width measurements.

質問 # 22
Refer to the exhibit (multi-use building with apartments, offices, stores, parking).
The multipurpose building shown is located in a cold-winter, mild-summer climate.
Which of the following is the best location for the mechanical equipment floor?
- A. Top floor
- B. Store level
- C. Between the office and apartment levels
- D. Parking level
正解：C
解説：
Comprehensive and Detailed Explanation From Exact Extract:
In mixed-use buildings in cold climates, placing mechanical equipment in a mid-level floor between different occupancy types (C) offers several benefits:
This location reduces the length and complexity of vertical distribution of heating and cooling systems to both apartments (above) and offices (below).
It avoids heat loss associated with exterior walls (as opposed to the top floor or parking level).
The equipment can be more centrally located, improving energy efficiency and system performance.
Locating equipment on the parking level (A) or store level (B) may require longer ductwork or piping runs and pose maintenance challenges.
The top floor (D) exposes mechanical equipment to outdoor weather, which is not ideal in cold climates.

質問 # 23
An architect is designing a multistory student housing project to be built of light wood framing. The following criteria must be met:
Minimize the floor assembly thickness
Maximize ceiling height
No individual HVAC room controls
No exposed ductwork
Which HVAC system should be selected for this project?
- A. Variable air volume (VAV)
- B. Four-pipe fan-coil system
- C. Packaged terminal units (PTAC)
正解：B
解説：
For multistory residential buildings such as student housing with light wood framing, HVAC system selection must balance space constraints and occupant comfort. The requirement to minimize floor thickness and maximize ceiling height typically rules out bulky ductwork or ceiling-mounted systems.
Packaged Terminal Air Conditioners (PTACs) provide individual room control and require wall penetrations, conflicting with the "no individual HVAC room controls" and likely leading to more complex maintenance.
Variable Air Volume (VAV) systems typically require extensive ductwork and ceiling space, contradicting the goal to minimize floor thickness and eliminate exposed ductwork.
The Four-pipe fan-coil system is an efficient choice for this application: it uses small fan coil units within the ceiling or wall cavities with chilled and hot water supply pipes running vertically. This system minimizes the thickness of mechanical floors and allows centralized control rather than individual room controls. The fan coil units can be concealed, addressing the "no exposed ductwork" criterion.
This approach aligns with NCARB's guidance on HVAC system selection for multifamily and residential occupancies where ceiling height and floor thickness are critical constraints, and centralized control systems are preferred for ease of maintenance and energy management.

質問 # 24
Click in the structural bay of the elevation that is the most appropriate location to install steel rod cross bracing.
正解：
解説：
Explanation:
the most appropriate location to install steel rod cross bracing is in the fourth structural bay, which corresponds to the bay on the far right side of the elevation.
* Steel rod cross bracing is typically installed in bays that are fully open or contain large door openings and require lateral support to resist racking forces (lateral loads such as wind or seismic forces).
* The fourth bay shows a large door opening without any visible solid wall or shear wall elements, making it structurally weaker against lateral loads and thus the most suitable for cross bracing.
* The first bay, with a smaller door or solid wall, and the other bays with more enclosed or glazed openings may have other structural elements providing lateral resistance.
* Installing the bracing in the fourth bay enhances structural stability and prevents lateral displacement or deformation.
質問 # 25
An architect has just received client approval of the Schematic Design documents for a three-story, outpatient medical clinic. The clinic is located within a mixed-use development governed by a City-approved Planned Development (PD) document. The medical clinic design utilizes standardized departmental layouts and includes outpatient clinics, as well as treatment spaces, administrative spaces and public/lobby spaces.
The site needs to accommodate four different vehicular traffic flows: patient traffic, staff traffic, service and delivery traffic, and emergency services traffic. In addition, a pedestrian plaza must connect to the mixed-use development sidewalks. The plaza must provide space for bicycle parking and will serve as the future bus stop.
The site design addresses several challenges related to building orientation. The southeast facade, with excellent visibility from the highway, is the location of all service equipment. The building entrance faces northwest, convenient to the parking but not visible from the highway.
The client believes future patient volumes will outgrow the clinic. The PD document allows for a planned Phase 2 development on the adjacent vacant site to the southwest. Phase 2 would include a second building (2 story, 80,000 BGSF) and/or a parking deck.
Other considerations for the project include:
* Protected tree requirements are defined in the PD document.
* Easy pedestrian access must be provided from Sycamore Boulevard.
* All required parking for the clinic must be accommodated on site.
* Programmed area includes 109,450 Departmental Gross Square Feet (DGSF) / 130,184 Building Gross Square Feet (BGSF).
* Exterior material percentages are dictated by the PD document and shall not exceed specific percentages for Primary and Secondary Finishes.
* All service equipment needs to be screened; see PD document for restrictions.
* Signage opportunities are important to the client.
* Acoustical privacy is a concern of the healthcare system.
The following resources are available for your reference:
* Drawings, including a perspective, plans, and exterior elevations
* Building Program, including client's departmental program and detailed program for Treatment 01 (Infusion)
* Exterior Material Cost Comparisons
* Planned Development Document
* IBC Excerpts, showing relevant code sections
* ADA Excerpts, showing relevant sections from the ADA Standards for Accessible Design After construction, the owner asks the architect to integrate sustainable features that would offset building operational costs and have minimal changes to the existing design and future development.
Which of the following sustainable features should the architect consider?
- A. Ground-mounted PV panels
- B. Roof-mounted PV panels
- C. Building-mounted vertical sunshades
正解：B
解説：
Comprehensive and Detailed Explanation From Exact Extract:
Roof-mounted photovoltaic (PV) panels are the most appropriate sustainable feature to offset building operational costs with minimal design changes, especially in a mixed-use development with planned future expansion.
Building-mounted vertical sunshades (A) require design integration and may affect exterior finishes and daylighting.
Ground-mounted PV panels (C) require additional land and site preparation, which could conflict with future development plans and site constraints.
Roof-mounted PV panels maximize use of existing roof space, reduce energy costs, and are relatively easy to integrate with minimal impact on building massing or future phases.

質問 # 26
A new four-story apartment building is being designed on a site that has solid bedrock subsurface conditions.
The client requested the lowest cost of installation, highest energy efficiency, the shortest round trip time, and minimized loss of usable building space.
Which elevator type should the architect recommend?
- A. Conventional hydraulic elevator
- B. Dual jack hole-less hydraulic elevator
- C. Machine-roomless elevator
- D. Gearless traction elevator
正解：C
解説：
Comprehensive and Detailed Explanation From Exact Extract:
Given the constraints:
Lowest cost of installation and minimized loss of usable space favor elevators that don't require a separate machine room.
Machine-roomless elevators (D) have compact machinery integrated within the hoistway, reducing space needs and construction costs.
Hydraulic elevators (A, C) require pits and often larger machine rooms, and are less energy efficient and have slower round trip times compared to traction types.
Gearless traction elevators (B) provide excellent speed and efficiency but usually require machine rooms, increasing cost and space.
Thus, machine-roomless elevators balance cost, efficiency, space, and speed best for mid-rise residential buildings.
