Mixed Deck — All Interior Design Topics Flashcards

A Janka hardness rating is used to measure which property of flooring materials?

Answer: Resistance to denting and wear

The Janka hardness test measures the force required to embed a steel ball into wood, indicating its resistance to dents and surface wear.

What is the primary goal of circadian (human-centric) lighting systems?

Answer: To support the body's natural 24-hour biological clock by adjusting color temperature and intensity throughout the day

Circadian lighting adjusts color temperature and intensity in alignment with natural daylight cycles — cooler and brighter at midday, warmer and dimmer in morning and evening — to support occupants' biological rhythms.

Which rendering technique simulates how light bounces between surfaces to create realistic ambient illumination?

Answer: Global illumination

Global illumination calculates indirect light that bounces off multiple surfaces, producing photorealistic ambient lighting effects.

In paint specification, LRV stands for which metric used in interior design?

Answer: Light Reflectance Value

Light Reflectance Value (LRV) measures the percentage of light a color reflects on a scale of 0 (pure black) to 100 (pure white), crucial for lighting design.

Please tick the term that represents a horizontal part that is placed over a huge aperture to support the weight above in the construction of a wall:

Answer: Lintel

A lintel is a horizontal structural member placed over an opening in a wall, such as a window or door. Its primary function is to support the weight of the wall or masonry directly above the opening. This prevents the wall from collapsing and ensures the structural integrity of the aperture.

How should an Interior Design professional approach a novel situation not covered by standard procedures?

Answer: Apply foundational principles, assess risks, consult resources, and document the rationale for decisions

This is fundamental to Interior Design practice. Apply foundational principles, assess risks, consult resources, and document the rationale for decisions represents the professional standard for practical in the Interior Design certification framework.

What does 'active listening' mean in a client consultation?

Answer: Fully concentrating, reflecting back what was heard, and asking clarifying questions

Active listening involves full engagement and verification of understanding, which builds trust and reduces scope misalignment.

Terrazzo flooring is composed of which materials?

Answer: Marble or granite chips set in cement or epoxy

Terrazzo consists of chips of marble, quartz, granite, or glass poured with a cement or epoxy binder, then ground and polished to a smooth finish.

Which tile installation pattern uses rectangular tiles arranged so the joints of one row align with the center of tiles in adjacent rows?

Answer: Running bond/brick

The running bond (or brick) pattern staggers tiles by half a length in each row, creating a classic, strong visual pattern familiar from brick walls.

Which space planning principle involves organizing a room layout so that a clear sightline is maintained from the entry to a focal point?

Answer: Axial planning

Axial planning arranges space along a dominant axis, creating sightlines and movement paths that draw the eye toward a focal point such as a fireplace or window.

How has digital technology transformed Interior Design practice?

Answer: It has enhanced data collection, analysis, communication, and operational efficiency

This is fundamental to Interior Design practice. It has enhanced data collection, analysis, communication, and operational efficiency represents the professional standard for technology in the Interior Design certification framework.

What is reflective practice in Interior Design professional development?

Answer: Systematically examining experiences to gain insight and improve future practice

This is fundamental to Interior Design practice. Systematically examining experiences to gain insight and improve future practice represents the professional standard for practical in the Interior Design certification framework.

Which design movement, originating in early 20th-century Germany, emphasized the unity of fine art, craft, and technology?

Answer: Bauhaus

The Bauhaus school, founded in 1919 by Walter Gropius, revolutionized design by merging artistic and functional disciplines.

What unit is used to measure illuminance — the amount of light falling on a surface?

Answer: Foot-candle

Foot-candles (or lux in SI units) measure illuminance — the quantity of light striking a surface per square foot.

What is the purpose of a 'punch list' communicated to a contractor at project close?

Answer: A documented list of incomplete or deficient items that must be corrected before project completion

A punch list ensures all parties have a shared, written record of outstanding work, preventing disputes at project handover.

Which countertop material is non-porous, heat-resistant, and composed of natural quartz crystals bound with resin?

Answer: Engineered quartz

Engineered quartz (e.g., Silestone, Caesarstone) is manufactured from 90–95% ground quartz and polymer resins, creating a non-porous, low-maintenance surface.

The standard counter height for kitchen work surfaces in US residential design is:

Answer: 36 inches

Standard US kitchen counters are 36 inches high, designed to be comfortable for an average-height adult standing at the work surface.

What is the primary purpose of using a 'proxy' object in a 3D scene with high-polygon furniture models?

Answer: To replace heavy geometry with a lightweight placeholder to improve viewport performance

Proxy objects use a simplified stand-in mesh in the viewport while linking to the full-detail model only at render time, keeping the scene responsive.

Why is it important to document all verbal agreements with clients in writing?

Answer: To provide a clear, shared record that prevents misunderstandings and protects both parties

Written documentation of verbal agreements eliminates ambiguity and serves as a reference point if any confusion arises later.

What distinguishes quality assurance from quality control in Interior Design practice?

Answer: QA focuses on preventing defects through process improvement while QC detects defects through inspection

This is fundamental to Interior Design practice. QA focuses on preventing defects through process improvement while QC detects defects through inspection represents the professional standard for quality in the Interior Design certification framework.
