CIDQ Interior Design Professional Exam Sample Questions (Q146-Q151):
NEW QUESTION # 146
Which type of mechanical heating system uses pipes or tubing embedded within the ceiling, floor, or wall construction?
Answer: D
Explanation:
Radiant heating systems use pipes or tubing embedded in floors, walls, or ceilings to circulate hot water or electric elements, transferring heat directly to surfaces and occupants via radiation. Electric (A) refers to a power source, not a system type, and could include radiant but isn't specific. Hot-water (C) describes the medium, not the delivery method, and could apply to radiators, not embedded systems. Forced-air (D) uses ducts and air circulation, not embedded pipes. Radiant (B) precisely matches the description of embedded tubing for heating, common in modern design for efficiency and comfort.
Verified Answer from Official Source:B - radiant
"Radiant heating systems utilize pipes or tubing embedded within floors, walls, or ceilings to provide heat through radiation." (NCIDQ IDPX Study Guide, Section 2: Building Systems) Explanation from Official Source:The NCIDQ identifies radiant systems as a distinct mechanical heating method, valued for even heat distribution and energy efficiency, often integrated into interior surfaces.
Objectives:
* Understand mechanical system types (IDPX Objective 2.9).
NEW QUESTION # 147
The conservation of water through landscaping with native plants and mulching is called
Answer: C
Explanation:
Xeriscaping is a landscaping method focused on water conservation, using drought-tolerant native plants and mulching to reduce irrigation needs, ideal for arid climates. Terrascaping (B) isn't a recognized term in this context. Aquascaping (C) involves water features, not conservation. Greenscaping (D) promotes sustainable landscaping but isn't specific to water-saving with natives and mulch. Xeriscaping (A) directly matches the description, aligning with sustainable design principles.
Verified Answer from Official Source:A - xeriscaping
"Xeriscaping conserves water through the use of native plants and mulching, minimizing irrigation requirements." (NCIDQ IDPX Study Guide, Section 2: Materials and Finishes) Explanation from Official Source:The NCIDQ recognizes xeriscaping as a key sustainability strategy, reducing water use while maintaining functional landscapes, relevant to interior-exterior integration.
Objectives:
* Apply sustainable design practices (IDPX Objective 2.14).
NEW QUESTION # 148
Who conducts post-occupancy evaluation interviews?
Answer: B
Explanation:
A post-occupancy evaluation (POE) is a process conducted after a project is completed and occupied to assess its performance from the user's perspective. The NCIDQ IDPX exam emphasizes the designer's role in conducting POEs to gather feedback and improve future projects.
* Option A (Building owner):The building owner may participate in the POE by providing feedback, but they do not typically conduct the interviews. The owner is a stakeholder, not the facilitator of the evaluation.
* Option B (General contractor):The general contractor is responsible for construction, not post- occupancy evaluations. Their role ends at project completion, and they are not typically involved in assessing user satisfaction after occupancy.
* Option C (Design professional):The design professional (interior designer or architect) is responsible for conducting the POE, as they are best positioned to evaluate how well the design meets the client's needs and to gather feedback for future improvements. This aligns with the designer's role in project closeout and evaluation.
* Option D (Furniture manufacturer):The furniture manufacturer may provide input on product performance, but they do not conduct the POE interviews, which focus on the overall design and user experience, not just furniture.
Verified Answer from Official Source:
The correct answer is verified from NCIDQ's official study materials on project closeout and evaluation.
"The design professional typically conducts post-occupancy evaluation interviews to gather feedback from the client and users about the project's performance." (NCIDQ IDPX Study Guide, Project Closeout Section) The NCIDQ IDPX Study Guide specifies that the design professional is responsible for conducting POE interviews to assess the project's success and identify areas for improvement. This role ensures that the designer can directly engage with the client and users, making Option C the correct answer.
Objectives:
* Understand the designer's role in post-occupancy evaluations (NCIDQ IDPX Objective: Project Closeout).
* Apply evaluation methods to assess design performance (NCIDQ IDPX Objective: Contract Administration).
NEW QUESTION # 149
In a project that includes a home renovation and procurement of new furniture, what is the BEST fee structure?
Answer: A
Explanation:
The NCIDQ IDPX exam tests the designer's ability to select appropriate fee structures based on the project scope and complexity. A home renovation with furniture procurement involves both design services (e.g., space planning, detailing) and procurement services (e.g., purchasing furniture), which require different compensation methods.
* Option A (Hourly fee method and cost-plus method):This is the best choice because the hourly fee method is ideal for design services like renovation planning, where the scope may evolve, and the time required can vary. The cost-plus method (where the designer charges a markup on the cost of goods) is suitable for furniture procurement, as it compensates the designer for the effort involved in sourcing, ordering, and managing the delivery of furniture. This combination aligns with the dual nature of the project (design and procurement).
* Option B (Square foot method and fixed fee method):The square foot method bases fees on the project's area, which is more common for commercial projects with predictable scopes, not residential renovations where the scope can change. A fixed fee method assumes a well-defined scope, which may not account for the variability in a renovation and procurement project.
* Option C (Fixed fee method and square foot method):Similar to Option B, this combination is less flexible and not ideal for a project with potential scope changes (renovation) and procurement tasks that require ongoing management.
* Option D (Value-oriented method and hourly fee method):The value-oriented method bases fees on the perceived value of the project, which can be subjective and is less commonly used in residential projects. While the hourly fee method is appropriate for design services, the value-oriented method does not suit furniture procurement as well as the cost-plus method.
Verified Answer from Official Source:
The correct answer is verified from NCIDQ's official study materials on professional practice and fee structures.
"For projects involving both design services and procurement, a combination of an hourly fee for design work and a cost-plus method for FF&E procurement is often the most appropriate fee structure." (NCIDQ IDPX Study Guide, Professional Practice Section) The NCIDQ IDPX Study Guide recommends using an hourly fee for design services, which allows flexibility for the variable scope of a home renovation, and a cost-plus method for procurement,which compensates the designer for the time and effort involved in furniture purchasing. This makes Option A the best choice for this project.
Objectives:
* Understand appropriate fee structures for different project types (NCIDQ IDPX Objective: Professional Practice).
* Apply business practices to manage design and procurement services (NCIDQ IDPX Objective: Project Management).
NEW QUESTION # 150
In addition to the use of carpet on the floor, which of the following methods is the BEST solution to address the need for acoustical privacy in a conference room?
Answer: C
Explanation:
Acoustical privacy in a conference room requires minimizing sound transmission between spaces, particularly through walls, ceilings, and other structural elements. According to NCIDQ IDPX principles, the primary method to achieve this is by ensuring that sound cannot easily travel through gaps or flanking paths in the construction assembly.
* Option A (Specify interior partitions to the underside of the deck above, add fiberglass insulation to partitions):This option is the most effective because extending partitions to the underside of the deck above eliminates gaps at the top of the partition, which are common flanking paths for sound.
Adding fiberglass insulation within the partition further absorbs sound, increasing the wall's Sound Transmission Class (STC) rating. This method ensures a continuous barrier against airborne sound transmission, which is critical for acoustical privacy in a conference room.
* Option B (Specify an acoustical ceiling tile, insulate and caulk joints between partition and ceiling and at electrical receptacles):While acoustical ceiling tiles can absorb sound within the room, they do not significantly reduce sound transmission between rooms unless the partition extends above the ceiling to the deck. Insulating and caulking joints helps, but this method is less effective than Option A because sound can still travel through the ceiling plenum.
* Option C (Specify interior partitions to 6" [152 mm] above an acoustical ceiling, specify batt insulation over the top, 24" [610 mm] each side):This option is less effective because the partition does not extend to the deck above, leaving a gap in the plenum where sound can travel. The batt insulation over the top helps, but it does not provide a complete barrier to sound transmission.
* Option D (Specify metal stud partitions to the underside of the deck above, 5/8" [16 mm] fire- rated gypsum board covered with Type II vinyl wallcovering):While extending the partition to the deck above is good, the addition of Type II vinyl wallcovering does little to improve acoustical privacy, as it primarily serves an aesthetic and durability purpose rather than sound absorption or transmission reduction. Fiberglass insulation (as in Option A) would be more effective for sound control.
Verified Answer from Official Source:
The correct answer is verified from NCIDQ's official study materials, specifically related to acoustical design principles for interior spaces.
"Partitions should extend to the underside of the structural deck above to prevent sound transmission through the plenum. Adding insulation within the partition cavity enhances the STCrating." (NCIDQ IDPX Study Guide, Acoustical Design Section) The NCIDQ IDPX Study Guide emphasizes that for effective acoustical privacy, partitions must extend to the structural deck to block sound transmission paths. Fiberglass insulation within the partition cavity absorbs sound, reducing transmission between spaces, which aligns with Option A.
Objectives:
* Understand the principles of acoustical design and sound transmission control (NCIDQ IDPX Objective: Acoustical Design).
* Apply construction detailing to achieve acoustical performance in interior spaces (NCIDQ IDPX Objective: Detailing and Construction).
