Free CIDQ IDPX Practice Exam with Questions & Answers | Set: 6

Window height directly affects daylight penetration depth, as taller windows allow light to reach further into a space, per IESNA daylighting principles. Shading devices (B) control light but reduce penetration. Glazing material (C) impacts light quality and quantity, not depth specifically. Reflective surfaces (D) enhance distribution, not initial penetration. Height (A) is the primary geometric factor determining how far light extends inward.

Verified Answer from Official Source:A - window height

"Window height is the primary factor determining the depth of daylight penetration into a space in daylighting design." (NCIDQ IDPX Study Guide, Section 2: Building Systems)

Explanation from Official Source:The NCIDQ emphasizes window height’s role in daylighting, critical for optimizing natural light and energy efficiency in interiors.

Objectives:

Design for daylighting efficiency (IDPX Objective 2.6).

An hourly fee is best for a small project with an unclear scope and multiple stakeholders, as it allows the designer to bill for actual time spent, accommodating scope changes and stakeholder input without financial risk. A fixed-fee (B) requires a defined scope, risky here due to uncertainty. Cost-plus (C) ties payment to costs plus a markup, more suited to construction than design services in this context. Square footage (D) depends on a known area, impractical with an unclear scope. Hourly (A) offers flexibility and fairness in an unpredictable scenario.

Verified Answer from Official Source:A - hourly

"An hourly fee is recommended for projects with undefined scopes or multiple stakeholders, allowing designers to adjust billing to actual effort." (NCIDQ IDPX Study Guide, Section 5: Professional Practice)

Explanation from Official Source:The NCIDQ highlights hourly fees as a low-risk method for designers when project parameters are fluid, ensuring compensation matches work performed.

Objectives:

Select appropriate fee structures (IDPX Objective 5.1).
