Question 1Programming and Pre-Design

During pre-design, an interior designer is assembling the client's program for a new outpatient clinic. Which document most appropriately establishes the quantitative space requirements before any schematic layouts are drawn?

  1. A reflected ceiling plan showing fixture locations
  2. A space program listing required areas, occupancy, and adjacency relationships Correct answer.
  3. A finish schedule organized by room number
  4. A furniture, fixtures, and equipment schedule keyed to a furniture plan

Explanation

The space program is the pre-design deliverable that converts client needs into quantified area requirements and functional relationships before design begins. FF&E schedules, finish schedules, and reflected ceiling plans are documentation produced during later design phases once layouts exist.

Question 2Programming and Pre-Design

A client tells the designer, "We need more conference rooms because our teams can never book one." Which pre-design research method would best test whether the real problem is room quantity or booking behavior?

  1. Counting the total number of employees on each floor
  2. Reviewing existing booking logs and observing peak-hour room use Correct answer.
  3. Measuring the square footage of each existing conference room
  4. Interviewing only the facilities manager about room counts

Explanation

Booking data and observation reveal actual utilization patterns, distinguishing a supply shortage from scheduling or behavioral problems. A single stakeholder interview or simple area measurement cannot capture how rooms are actually used throughout the day.

Question 3Programming and Pre-Design

In a programming report, which item is a constraint rather than a goal?

  1. Achieve a welcoming arrival experience
  2. The leased floor plate cannot exceed 1,200 square meters Correct answer.
  3. Support future expansion of the clinical staff
  4. Increase collaboration among departments

Explanation

Constraints are fixed limits imposed on the project, such as lease area, budget, code, or existing structure. Goals describe desired outcomes the design should achieve and are typically qualitative aspirations.

Question 4Programming and Pre-Design

A designer is preparing an adjacency matrix for a hospital department. What does a strong value in a cell between two rooms most directly indicate?

  1. The two rooms should be physically close or directly connected Correct answer.
  2. The two rooms must share the same HVAC zone
  3. The two rooms must be separated by a fire-rated wall
  4. The two rooms require identical finishes

Explanation

An adjacency matrix scores the strength of desired proximity or connection between pairs of spaces. It communicates functional relationships, not code separation, finish uniformity, or mechanical zoning.

Question 5Programming and Pre-Design

A programming interview with a client reveals that the number of private offices requested would consume 60 percent of the available floor area. What is the most appropriate designer response during pre-design?

  1. Delete the offices from the program to balance the budget
  2. Accept the request and resolve the shortfall during construction documents
  3. Present the area conflict to the client and facilitate prioritization of needs Correct answer.
  4. Reduce the office sizes without informing the client

Explanation

Programming is where conflicts between wants, area, and budget are surfaced and resolved with the client through prioritization. Unilaterally changing or deferring the conflict undermines the client's decision-making role.

Question 6Programming and Pre-Design

Which pre-design activity best establishes the project budget basis before schematic design begins?

  1. Selecting furniture from a showroom catalog
  2. Finalizing the finish schedule with the client
  3. Requesting contractor bids on a completed drawing set
  4. Comparing benchmark cost per square meter against the programmed area Correct answer.

Explanation

Early budgeting uses benchmarking and area-based estimating against the program to set a realistic cost envelope. Bidding requires completed documents, and furniture or finish selections occur later and do not establish the overall budget.

Question 7Programming and Pre-Design

During a programming workshop, the designer asks staff to place colored dots on a plan to indicate where they perform each major task. Which technique is being used?

  1. Code analysis
  2. Behavior mapping Correct answer.
  3. Value engineering
  4. Post-occupancy evaluation

Explanation

Behavior mapping records where activities actually occur, often using plan-based marking exercises with users. It captures functional use patterns that inform the program and adjacencies.

Question 8Programming and Pre-Design

A client insists that the new office must achieve a specific green building certification. In programming terms, how should this requirement be classified?

  1. An optional design feature
  2. A post-occupancy metric
  3. A constraint that shapes design decisions Correct answer.
  4. A goal to be balanced against other aspirations

Explanation

A mandatory certification is a fixed requirement that bounds the design solution, making it a constraint. Goals are desired outcomes that can be traded off, whereas a required certification cannot simply be dropped.

Question 9Programming and Pre-Design

Which information source is most reliable for establishing existing conditions of a leased space before renovation programming?

  1. The landlord's marketing brochure
  2. A site survey and review of as-built drawings Correct answer.
  3. Verbal descriptions from building staff
  4. The previous tenant's furniture plan

Explanation

A measured site survey combined with as-built documentation provides verifiable data on dimensions, structure, and systems. Marketing materials and informal sources may be outdated or inaccurate.

Question 10Programming and Pre-Design

A designer is calculating the net assignable area for a program. Which space should typically be counted as net assignable area rather than as circulation or building support?

  1. A private office Correct answer.
  2. The mechanical equipment room
  3. The main public corridor
  4. The elevator lobby

Explanation

Net assignable area includes spaces that directly serve the occupant's program, such as offices, workstations, and conference rooms. Corridors, mechanical rooms, and elevator lobbies are support or circulation areas counted separately.

Question 11Programming and Pre-Design

Which programming deliverable would a designer use to communicate to the client the total area required by department, including a growth factor?

  1. A finish legend
  2. A stacking diagram
  3. A space program summary with net and gross areas Correct answer.
  4. A door schedule

Explanation

A program summary tabulates net assignable areas and applies a circulation or grossing factor to yield total building area. Stacking diagrams show vertical organization, while finish legends and door schedules are later documentation.

Question 12Programming and Pre-Design

During a visioning session, the client states a goal of "flexibility for future growth." Which programming decision best operationalizes this goal?

  1. Selecting a single large conference room
  2. Reducing storage to maximize open area
  3. Specifying fixed private offices for every manager
  4. Designing modular workstations and demountable partitions Correct answer.

Explanation

Modular and demountable systems allow the layout to be reconfigured as needs change, directly supporting a flexibility goal. Fixed offices and inflexible room types work against adaptability.

Question 13Programming and Pre-Design

A designer is developing a functional relationship diagram during programming. What is its primary purpose?

  1. To show the exact dimensions of each room
  2. To specify structural framing
  3. To document the project schedule
  4. To illustrate desired proximity and circulation between spaces Correct answer.

Explanation

Bubble or relationship diagrams communicate desired adjacencies and circulation flows without committing to dimensions or geometry. They translate program relationships into a visual organizing concept.

Question 14Programming and Pre-Design

A client asks the designer to program a new facility for a business they plan to launch in three years. Which approach best addresses the uncertainty?

  1. Use scenario planning with base and growth cases Correct answer.
  2. Assume maximum occupancy for every space
  3. Program only for current known needs and ignore growth
  4. Delay programming until the business launches

Explanation

Scenario planning lets the program accommodate uncertain futures by defining base and growth cases with associated area ranges. Ignoring growth, over-programming everything, or delaying all work leaves the client unprepared.

Question 15Programming and Pre-Design

In a programming report, which item best represents an assumption the designer should explicitly document?

  1. The client's stated headcount for year one Correct answer.
  2. The measured column grid from the site survey
  3. The required egress width calculated from code
  4. The building code occupancy classification confirmed by the authority

Explanation

Assumptions are unverified inputs taken as true for planning purposes, such as projected headcount, and must be documented so they can be validated. Measured and code-confirmed items are verified facts, not assumptions.

Question 16Programming and Pre-Design

A designer is conducting a stakeholder interview for a new library. Which question is most effective for uncovering functional requirements?

  1. Which contractor should we hire?
  2. How much do you think the project will cost?
  3. Walk me through a typical day and where each activity happens Correct answer.
  4. Do you prefer blue or green finishes?

Explanation

Open-ended questions about actual tasks and locations reveal functional needs and adjacencies. Questions about finishes, contractors, or budget do not elicit programming information about space use.

Question 17Programming and Pre-Design

A program identifies that the pharmacy must be adjacent to the nursing station but remote from the public waiting area. How should the designer represent these two relationships in an adjacency matrix?

  1. No values, since adjacency cannot express separation
  2. Identical high values for both pairs
  3. A high value between pharmacy and nursing station and a low value between pharmacy and waiting Correct answer.
  4. A low value between pharmacy and nursing station and a high value with waiting

Explanation

An adjacency matrix scores desired proximity with high values and desired separation or distance with low values. Recording a high value for the nursing station and a low value for the waiting area captures both requirements.

Question 18Programming and Pre-Design

Which factor most directly determines the grossing factor applied to net assignable area when estimating total building area?

  1. The brand of HVAC equipment specified
  2. The number of electrical outlets per room
  3. The proportion of circulation and support space required Correct answer.
  4. The color palette selected for the interior

Explanation

The grossing factor accounts for circulation, walls, mechanical, and other support space beyond net assignable area. Finishes, outlets, and equipment brands do not determine the ratio of gross to net area.

Question 19Programming and Pre-Design

A programming team discovers that two departments have conflicting adjacency needs, each requesting to be next to the shared service core. What is the most appropriate next step?

  1. Ignore the conflict and resolve it during construction documents
  2. Assign the core to the department that asked first
  3. Split the core into two smaller cores to satisfy both
  4. Document the conflict and facilitate a joint prioritization meeting Correct answer.

Explanation

Conflicting requirements are resolved by transparently documenting the conflict and facilitating a decision among stakeholders. Arbitrary assignment or deferral leaves the program unresolved and risks later redesign.

Question 20Programming and Pre-Design

Which pre-design document typically records the client's approval of the program before schematic design proceeds?

  1. A punch list
  2. A signed program approval or sign-off Correct answer.
  3. A certificate of occupancy
  4. A construction change order

Explanation

Client sign-off on the program confirms agreement on scope and requirements before design advances. Change orders, punch lists, and occupancy certificates all belong to construction or post-construction phases.

Question 21Space Planning and Adjacencies

In a commercial office planning project, which planning ratio is used to estimate the gross building area required from a known net usable office area?

  1. Rentable-to-usable ratio
  2. Efficiency ratio
  3. Occupancy load factor
  4. Net-to-gross ratio Correct answer.

Explanation

The net-to-gross ratio expresses net usable area as a percentage of gross building area, so gross area equals net area divided by that ratio. It is the standard tool for early program-to-building sizing.

Question 22Space Planning and Adjacencies

A tenant program totals 18,000 net usable square feet and the planner assumes a net-to-gross ratio of 0.75. What gross building area should the planner budget?

  1. 24,000 gsf Correct answer.
  2. 18,750 gsf
  3. 27,000 gsf
  4. 13,500 gsf

Explanation

Gross area equals net usable area divided by the net-to-gross ratio: 18,000 / 0.75 = 24,000 gross square feet. Dividing rather than multiplying is essential because gross area is always larger than net usable area.

Question 23Space Planning and Adjacencies

In office space planning, what does the term "usable area" typically exclude?

  1. Building core elements such as elevators, stairs, and public restrooms Correct answer.
  2. Conference rooms and break areas
  3. Workstations and private offices
  4. Primary circulation corridors within the tenant space

Explanation

Usable area is the area available for tenant occupancy and excludes building core and shell elements such as elevator shafts, public stairs, and shared restrooms. Workstations, offices, and internal circulation are all counted as usable.

Question 24Space Planning and Adjacencies

A planning team is laying out an open office and wants to reduce visual distraction while keeping seated sightlines open. Which workstation configuration best supports this goal?

  1. Parallel workstations oriented so occupants face away from adjacent circulation
  2. Radial clusters facing a central aisle
  3. Back-to-back workstations with low screens and side panels Correct answer.
  4. Benching with high solid panels on all four sides

Explanation

Back-to-back arrangements with low screens and side panels block lateral sightlines while preserving an open feel and seated privacy. Full-height enclosure or facing circulation increases distraction and enclosure.

Question 25Space Planning and Adjacencies

Which planning strategy most directly reduces distraction in a dense open office without adding enclosed rooms?

  1. Orienting workstations so seated occupants do not face main circulation paths Correct answer.
  2. Placing all circulation at the building perimeter
  3. Increasing workstation panel height to full ceiling height
  4. Reducing the number of shared printers

Explanation

Orienting seated occupants away from high-traffic paths limits visual and auditory interruption, a core open-plan planning tactic. Full-height panels or perimeter-only circulation create other problems without solving layout efficiency.

Question 26Space Planning and Adjacencies

Under typical egress planning, the maximum travel distance from the most remote point of a sprinklered business occupancy to an exit is generally limited to approximately:

  1. 200 feet
  2. 150 feet
  3. 300 feet
  4. 250 feet Correct answer.

Explanation

Model codes commonly allow about 250 feet of travel distance in fully sprinklered business occupancies, with shorter limits for unsprinklered spaces. The exact figure must always be confirmed against the locally adopted code.

Question 27Space Planning and Adjacencies

A long, double-loaded corridor serves offices on both sides. Which planning measure best improves wayfinding at the corridor's midpoint?

  1. Painting the corridor a single uniform color throughout
  2. Adding a daylighted break or feature node with signage at the midpoint Correct answer.
  3. Increasing corridor width from 44 to 48 inches
  4. Removing all door numbers to reduce visual clutter

Explanation

A visible node or daylight feature at the midpoint gives occupants a landmark and shortens perceived corridor length. Uniform treatment and removal of signage remove the cues people rely on.

Question 28Space Planning and Adjacencies

In adjacency diagramming, a "primary" adjacency between two departments means they should be:

  1. Separated by a buffer zone to reduce conflict
  2. Located on separate floors connected by elevators
  3. Directly connected or immediately adjacent with shared access Correct answer.
  4. Connected only through a shared public lobby

Explanation

Primary adjacencies represent the strongest functional relationship and call for direct connection or immediate proximity. Secondary and undesirable adjacencies are handled with buffers or separation.

Question 29Space Planning and Adjacencies

A hospital department requires a "negative" adjacency with a noisy mechanical room. How should the planner respond?

  1. Place them immediately adjacent to simplify mechanical runs
  2. Stack them vertically with direct stair connection
  3. Combine them into a single shared zone
  4. Separate them with a buffer such as storage, circulation, or a service zone Correct answer.

Explanation

A negative adjacency means the two functions conflict and should be separated by distance or an intervening buffer. Placing them adjacent or combining them would transmit noise and vibration into the sensitive department.

Question 30Space Planning and Adjacencies

In a bubble diagram, the width or weight of the connecting line between two departments most commonly represents:

  1. The strength or priority of the adjacency relationship Correct answer.
  2. The required fire separation rating
  3. The number of occupants in each department
  4. The construction cost of the shared wall

Explanation

Line weights in adjacency diagrams encode the strength of the relationship, distinguishing primary, secondary, and undesirable adjacencies. Bubble size typically represents area, not line weight.

Question 31Space Planning and Adjacencies

A client wants the reception, main conference rooms, and mailroom grouped near the public entrance. Which planning principle most directly justifies this grouping?

  1. Separating by lease boundary
  2. Zoning by public versus private access Correct answer.
  3. Stacking by structural bay
  4. Grouping by mechanical load

Explanation

Grouping public-facing functions near the entry applies zoning by access level, keeping visitors out of private work zones. Structural, mechanical, and lease considerations do not drive this grouping.

Question 32Space Planning and Adjacencies

A planner is arranging a suite so that visitors never pass through the private work zone to reach the conference center. This is an application of which zoning concept?

  1. Rentable area allocation
  2. Stacking
  3. Public-to-private gradient Correct answer.
  4. Structural modulation

Explanation

A public-to-private gradient sequences spaces from the most public at the entry to the most private deep in the suite. Visitors are intercepted before entering private zones, protecting confidentiality and focus.

Question 33Space Planning and Adjacencies

Which factor most strongly drives the maximum depth of a floor plate in a speculative office building?

  1. The ability to provide daylight and views to occupied spaces Correct answer.
  2. The number of parking spaces provided
  3. The color of the exterior curtain wall
  4. The number of elevators in the core

Explanation

Floor plate depth is governed primarily by daylight and view access, typically limiting depth to roughly 45 to 50 feet from a window wall. Elevators, facade color, and parking do not set plate depth.

Question 34Space Planning and Adjacencies

For a typical office floor plate, what maximum distance from a window wall is commonly used as a rule of thumb to ensure reasonable daylight penetration?

  1. 90 to 100 feet
  2. 45 to 50 feet Correct answer.
  3. 65 to 70 feet
  4. 20 to 25 feet

Explanation

A common rule of thumb limits daylighted depth to roughly 45 to 50 feet from the window wall, which also supports a double-loaded corridor layout. Deeper zones rely on artificial light.

Question 35Space Planning and Adjacencies

A building core placed at the center of a square floor plate with offices on all four sides is described as which planning configuration?

  1. End-core
  2. Central-core Correct answer.
  3. Side-core
  4. Offset-core

Explanation

A central-core configuration places the core in the middle so that perimeter window frontage is maximized on all sides. Side-core and end-core schemes concentrate the core at an edge.

Question 36Space Planning and Adjacencies

A tenant requires a large open trading floor that must remain column-free. Which building selection criterion is most critical?

  1. Elevator cab finish
  2. Column spacing and bay dimensions Correct answer.
  3. Lobby ceiling height
  4. Window mullion color

Explanation

A column-free trading floor depends on structural bay dimensions and column spacing, which determine the largest clear span available. Finish and height items do not affect clear span.

Question 37Space Planning and Adjacencies

In programming, the term "net assignable area" refers to space that is:

  1. Directly assigned to a specific function or occupant Correct answer.
  2. Shared by all tenants in a multi-tenant building
  3. Reserved for future expansion
  4. Devoted to circulation and mechanical shafts

Explanation

Net assignable area is the portion of a space directly usable for its intended function, excluding circulation, walls, and core. It forms the basis of a program's room-by-room area schedule.

Question 38Space Planning and Adjacencies

A workplace planner is deciding between benching and individual L-shaped desks for a team of 40 analysts who collaborate frequently. Which arrangement best supports frequent collaboration while preserving individual focus?

  1. Cubicles with full-height panels
  2. Private enclosed offices for every analyst
  3. Benching with low dividers and shared side tables Correct answer.
  4. Fully open tables with no dividers

Explanation

Benching with low dividers supports quick interaction and shared work surfaces while providing a minimal focus cue. Private offices and full-height cubicles isolate people, and fully open tables remove any focus support.

Question 39Space Planning and Adjacencies

An organization wants a "neighborhood" planning approach in a new headquarters. What does this concept primarily organize?

  1. Building mechanical systems into zones
  2. Workstations into small clusters with nearby support spaces and shared amenities Correct answer.
  3. Parking into assigned blocks
  4. The structural grid into equal bays

Explanation

Neighborhood planning groups workstations into manageable clusters served by nearby meeting, focus, and amenity spaces. It is a social and functional organization strategy, not a mechanical or structural one.

Question 40Space Planning and Adjacencies

A planner must place a 12-person conference room, a 4-person focus room, and a phone booth within a work neighborhood. Which placement logic best supports daily use?

  1. Place all enclosed rooms along the window wall for views
  2. Cluster all three at the building's far end to consolidate noise
  3. Locate all rooms immediately adjacent to the main entry
  4. Distribute them within the neighborhood so no workstation is more than a short walk away Correct answer.

Explanation

Distributing meeting and focus rooms throughout the neighborhood keeps travel short and supports frequent, spontaneous use. Consolidating them or placing them at the entry increases walking distance and concentrates noise.

Question 41Space Planning and Adjacencies

When planning a suite, the primary circulation system should generally connect which elements?

  1. Only the private offices
  2. The building exterior only
  3. Only the restrooms and mechanical rooms
  4. The main entry, vertical circulation, and major destinations, with secondary paths branching to individual spaces Correct answer.

Explanation

Primary circulation links the entry, elevators, and major destinations, while secondary paths branch off to individual spaces. This hierarchy keeps major traffic efficient and reduces disruption to work areas.

Question 42Space Planning and Adjacencies

A tenant's program requires a data center adjacent to the main office. Which adjacency consideration is most critical to resolve early in planning?

  1. Color of the data center flooring
  2. View access from the data center
  3. Heat, noise, and security separation from occupied workspace Correct answer.
  4. Proximity to the main entrance for visitors

Explanation

Data centers generate heat and noise and require controlled access, so separation and buffering from occupied space must be resolved early. Aesthetic and view considerations are secondary for an equipment space.

Question 43Space Planning and Adjacencies

In a medical office, exam rooms are typically clustered around a shared provider work zone rather than dispersed along the public corridor. What planning rationale best explains this?

  1. It improves provider efficiency and patient privacy by separating clinical and public circulation Correct answer.
  2. It allows exam rooms to be smaller
  3. It eliminates the need for a waiting area
  4. It reduces the number of required exits

Explanation

Clustering exam rooms around a provider zone creates a clinical core that separates patient and staff circulation and shortens provider travel. It does not change exit requirements or room sizes.

Question 44Space Planning and Adjacencies

A planner is comparing two floor plates for a law firm: one with a central core and one with a side core. Which statement best captures the trade-off?

  1. The side core always provides more daylight to private offices
  2. The central core maximizes perimeter window frontage but concentrates circulation in the middle Correct answer.
  3. The central core eliminates the need for corridors
  4. The side core reduces the building's rentable area

Explanation

A central core pushes circulation to the middle and maximizes perimeter frontage for offices and daylight. A side core concentrates circulation at one edge and creates uneven daylight zones.

Question 45Space Planning and Adjacencies

Which planning document most directly communicates the required relationships among departments before any floor plan is drawn?

  1. Door schedule
  2. Adjacency matrix Correct answer.
  3. Reflected ceiling plan
  4. Finish schedule

Explanation

The adjacency matrix records the strength and desirability of relationships among departments and is used before layout begins. Finish, door, and ceiling documents describe built elements after design development.

Question 46Space Planning and Adjacencies

In space planning, the term "gross building area" is best defined as which of the following?

  1. The area of a floor measured to the inside face of the exterior walls, excluding the core
  2. The total enclosed area of all floors measured to the outside face of the exterior walls, including the core and structure Correct answer.
  3. The rentable area of a tenant suite after the core is deducted
  4. The sum of net assignable areas plus the circulation that serves them

Explanation

Gross building area is measured to the outside face of the exterior walls and includes everything within the building envelope, such as cores, structure, and mechanical space. Net assignable area and circulation are subsets of the gross area rather than its definition.

Question 47Space Planning and Adjacencies

A tenant program lists a mailroom that generates frequent cart traffic, a quiet legal library, and a client conference center. Which placement best satisfies typical adjacency logic?

  1. Library near the service elevator to simplify deliveries, conference center at the perimeter
  2. All three grouped together to minimize total travel distance from the elevator lobby
  3. Mailroom and library adjacent to each other at the building core, conference center at the perimeter
  4. Mailroom near the service elevator, conference center near the public lobby, library remote from both Correct answer.

Explanation

The mailroom belongs near service circulation to keep cart traffic out of quiet and client areas, while the conference center benefits from proximity to the public entrance for visitor access. The library should be separated from noisy, high-traffic functions rather than placed beside them.

Question 48Space Planning and Adjacencies

A planner is laying out a 40-desk open office and must decide how much space to allocate to primary versus secondary circulation. Which approach reflects accepted planning practice?

  1. Circulation should be minimized to the code minimum everywhere to maximize desk count
  2. Primary aisles should be wider and connect major destinations, while secondary aisles are narrower and provide local access to workstations Correct answer.
  3. Secondary aisles should be wider than primary aisles because they carry more daily foot traffic
  4. Primary and secondary aisles should be identical in width so the layout reads as uniform

Explanation

Primary circulation is the main network linking entrances, cores, and major destinations, so it is sized wider for volume and clarity. Secondary circulation feeds individual workstations from that network and can be narrower.

Question 49Space Planning and Adjacencies

An engineering firm wants its project teams to sit near the specialists they consult daily, but the specialists serve all teams. Which planning strategy best resolves this adjacency conflict?

  1. Place all specialists in a single remote department far from every team
  2. Distribute specialists into team neighborhoods and co-locate shared specialized equipment in a central lab Correct answer.
  3. Seat each team in a separate building so no team has an adjacency advantage
  4. Assign specialists to the team with the largest headcount and require others to travel

Explanation

When a shared resource has strong adjacency to several groups, distributing staff into neighborhoods while centralizing specialized equipment balances access for all teams. This avoids favoring one group and keeps high-cost shared assets in one controlled location.

Question 50Space Planning and Adjacencies

A planner compares a deep, 120-foot-deep floor plate against a shallow, 60-foot-deep plate for a tenant whose staff all need daylight at their workstations. Which analysis is most accurate?

  1. The shallow plate allows workstations to sit within the daylight zone from two window walls, reducing reliance on artificial light Correct answer.
  2. The deep plate is preferable because a larger floor plate always improves workstation adjacency
  3. Both plates perform identically because daylight penetration depends only on window head height
  4. The deep plate will require more core area, so it will automatically provide better daylight access for all staff

Explanation

In a shallow plate, workstations are more likely to fall within the daylight zone measured from the window wall, and a narrow plate can be daylit from both sides. A deep plate pushes more area into the interior where daylight does not reach.
