Small enclosed workpoints need their own notes
Focus rooms, quiet rooms and call booths are often counted as office space, but their lighting note is smaller than an open office or meeting room. A person may work at a narrow desk, look into a camera, read notes, turn toward a side wall and sit inside a booth shell that shades the face from the main ceiling light. A single room value can miss the desk surface, face plane, screen view and local control state.
Keep this note beside the office sector page, the office lighting guide, open-plan desk guide and meeting-room presentation guide. Those pages cover wider desk rows, shared rooms and presentation walls. This page stays with one small enclosed workpoint: desk surface, seated face, screen direction, acoustic-panel shadowing, glare, daylight note, sensor state and measured readings.

The useful note is not a whole-office average. It is a compact description of the small workpoint, written so a later reading can repeat the same planes under the same light state.
Desk plane and booth geometry
The desk plane is usually the first surface to name. In a call booth, it may be a shallow shelf, a small table or a built-in ledge under a screen. The note should say whether the measured area is the keyboard strip, notebook area, laptop stand, document ledge or the whole desk surface. A workplace lighting estimate can stay with the assessed desk area, while a room lighting estimate can describe the tiny enclosure only when the area, ceiling height and surface reflectance are known.
Booth geometry matters. A side return, acoustic lining, low ceiling baffle or dark rear panel can shade the desktop even when the room outside is bright. Note booth depth, desk height, seated side and any overhanging shelf before comparing a value with an office table. The task-plane table is the right place for plane height, surface role and point labels.
| Desk condition | Good note wording | Boundary |
|---|---|---|
| Built-in shelf | Booth B1 desk shelf, seated side, keyboard strip and note area. | Does not describe face lighting or screen reflection. |
| Small focus table | Focus room F2 table plane, normal seated side, laptop and paper area. | Does not stand for an open-plan desk row. |
| Side writing ledge | Side ledge plane, body turned right, booth shell shading noted. | Does not describe the main desk plane. |
| Door-side spill | Desk edge near open door, door state noted. | Does not represent the closed-door condition. |
| Standing call shelf | Standing shelf plane, user height and screen position noted. | Does not describe a seated workpoint. |
Measured desk readings should stay on the same plane. The lux meter average calculator can summarise several desk points only when the point labels, plane height and control state match. A face reading, floor reading or screen note should remain distinct.
| Point label | Location | Plane and condition |
|---|---|---|
| D1 desk centre | Keyboard and notebook zone. | Horizontal desk plane, screen on, normal occupied scene. |
| D2 desk front edge | User-side edge where hands and notes sit. | Horizontal desk plane, door state noted. |
| D3 desk rear | Screen base or rear shelf strip. | Horizontal plane, overhang or wall shadow noted. |
| W1 left panel | Acoustic side panel beside the seated user. | Vertical surface, finish and shadow direction noted. |
| W2 rear panel | Camera background behind the seated user. | Vertical surface, finish and screen state noted. |
| G1 glass or door | Door glass, side glass or open entry edge. | Vertical surface or reflection view, open or closed state noted. |
Face plane for video calls
Video-call visibility is the main reason a focus-room note differs from a general office note. A person may have acceptable light on the desk while the face is shaded by a booth side wall, backlit by a window, or flattened by a bright screen. The note should name the seated face plane and camera direction before any value is compared.
The vertical illuminance term is useful here because the meter faces the seated person or the camera side, not the desktop. Note the face height, camera position, background finish and whether the screen was on. A reading taken with a blank dark screen may not describe a bright video-call screen state.
| Face condition | Worksheet field | Why it has its own line |
|---|---|---|
| Camera-facing face | Vertical meter at normal seated face height, aimed toward the user from the camera side. | Desk lux does not describe face brightness. |
| Side shadow | Left or right cheek shadow from booth return, shelf or screen. | A room average can hide asymmetry. |
| Backlit seat | Window or bright corridor behind the person. | Camera contrast differs from the face-plane reading. |
| Dark background | Rear panel colour, depth and brightness noted. | Background balance is not a desk-plane result. |
| Screen-lit face | Screen on, brightness setting if visible, colour cast noted. | Electric lighting and screen contribution are mixed unless noted. |
The note should remain modest. It can describe face-plane lighting evidence for a camera view; it does not assess video quality, room-use rules, acoustic performance or meeting-room scope.
| Face or camera point | Label | Condition to write beside it |
|---|---|---|
| Camera-side face | F1 | Meter at seated face height, facing the user from the camera side. |
| Side-shadow check | F2L or F2R | Meter at cheek side, return wall or shelf shadow named. |
| Background view | B1 | Rear wall, curtain, glass or panel finish behind the user. |
| Screen contribution | S1 | Screen on or off, brightness note if visible, colour cast noted. |
| Backlight condition | BL1 | Window, corridor or glass door behind the user named. |
Screen, glare and reflected light
Small rooms can create noticeable reflected glare because the viewer sits close to a screen, glass door, glossy desktop or bright fitting. The glare entry and glare check guide can hold the observer position, bright object and reflected surface. For a booth, the short note should name seat position, screen angle, reflected patch and active control state.
Do not mix screen observations into a desk average. Screen contrast, reflected fittings and face visibility are individual note lines. Where a screen is close to the wall, also note whether the wall behind the screen is bright, dark, patterned or shiny. That background can affect perceived contrast even when measured illuminance on the desk is steady.
| Glare or reflection condition | Workpoint note | Keep apart from |
|---|---|---|
| Screen reflection | Seated view, screen angle and reflected fitting or window patch. | Desktop illuminance average. |
| Glossy desk | Bright patch on keyboard strip, notebook area or desk edge. | Face-plane reading. |
| Glass door | Reflected corridor light visible from seat. | Closed-booth desk value. |
| Bright side panel | Pale acoustic panel beside screen, view direction noted. | General room value. |
| Camera flare view | Bright background or screen edge in camera direction. | Meeting-room wall notes. |
A short glare note is usually enough: booth ID, seat side, screen direction, bright object and affected surface. Longer glare notes can sit with the dedicated glare page.
The surface reflectance and room finishes guide is the better supporting page when a dark acoustic lining, pale return wall, glossy desktop or glass door is changing the reading context. Keep reflectance as a surface note, not as a claim about the whole booth.
Sensor, dimmer and daylight states
A focus room may be controlled by a booth occupancy sensor, a local switch, a shared perimeter group, daylight-linked dimming or a cleaning scene. Readings belong only to the state that was active. The lighting control table keeps lighting zone, scene, dimming state and daylight condition beside the number.
Daylight needs special care in small rooms. A booth near a window can have useful daylight on one side and a dark face from the camera side. A fully enclosed booth may receive no daylight but still receive spill from a glass door. Note window side, blind state, door state and time of day where those conditions affect the plane.
| Control or daylight field | Focus-room wording | Why it matters |
|---|---|---|
| Lighting zone | Booth internal group, focus room ceiling group or shared office edge. | Prevents values from drifting into a whole-office claim. |
| Scene state | Normal, dimmed, presentation, after-hours or cleaning state. | A measured value belongs to one scene. |
| Sensor state | Occupied, timed hold, manual override or state unknown. | Small rooms can change level during reading. |
| Daylight note | Window side, blinds, door glazing, corridor spill or night check. | Face and screen readings can change quickly. |
| Door state | Open, closed or partly open during reading. | Spill light and reflections may change. |
Where several readings are gathered, the lux meter reading condition log keeps meter status, daylight, point label and control state together.
| Paired condition | First reading | Second reading | Page for the comparison |
|---|---|---|---|
| Daylight-only against electric-only | Same desk or face point, lights off, daylight condition written. | Same point after dark or with daylight excluded where practical. | daylight and electric lighting guide |
| Door closed against door open | Desk, face or glass point with door closed. | Same point with door open or partly open. | Lux meter before and after notes |
| Blind open against blind adjusted | Same point, blind open and time written. | Same point, blind state changed and time written. | Daylight shading and blinds reading notes |
| Booth scene against cleaning scene | Same point under normal occupied scene. | Same point under the named alternate scene. | lighting control table |
| Window-side booth against enclosed booth | Equivalent labelled desk or face point in each space. | Matching point in the second space, surface finishes noted. | window and skylight daylight guide |
Colour quality and connected load
Colour appearance can matter in a booth because camera-facing skin tones, screen content, paper notes and background panels are all close together. Keep colour temperature and CRI notes beside the exact surface being judged. The colour quality table keeps CCT, CRI/Ra, surface material and active scene in one row.
Connected load is only relevant when the booth or focus room is being compared as an energy zone. A lighting power density estimate can describe watts over a defined small room area. connected load table and business lighting energy table can hold watts, operating hours and control assumptions. Those notes do not replace desk, face or screen visibility notes.

The value of the note is the separation between desk, face and screen. A focus room can look bright enough from the doorway while the seated face sits in side shadow, the screen reflects a fitting, or the desk value changes when the door closes. A useful note names each plane, the active control state and the light condition before any comparison is made.
