Office lighting map
Office lighting should be recorded by work zone, not tenancy name. Open-plan desks, enclosed offices, meeting rooms, reception counters, collaboration areas, print zones, amenities, store rooms and circulation paths can sit inside one fitout while needing different task planes, glare notes and control groups.
The workplace lighting calculator is the main office route when a maintained work zone has a defined area, target illuminance, luminaire output, utilisation factor and maintenance factor. The workplace lighting table and Australian lighting level planning table keep office estimates anchored to Australian planning context without turning a public estimate into AS/NZS approval.
For the longer office method, keep the office lighting guide beside the record. That guide carries the deeper task-plane, screen-comfort, daylight and control discussion. This sector page stays narrower: it points each office question to the right calculator, table or record note so the estimate does not become one blended whole-floor number.
Search intent split by work record
Office searches often sound like one maintained-light question, but the record should split by workstation, meeting surface, vertical face, screen view, daylight row and control state before a result is compared.
| Search phrasing | Stronger lighting record | Why it should stay separate |
|---|---|---|
| Office lighting levels | Task type, assessed plane, work zone, target basis and Australian planning context. | One whole-floor number can hide desks, paths, counters and meeting walls. |
| Desk lighting | Desktop plane, screen direction, daylight side, fitting row, control group and open-plan desk record. | Desk comfort depends on reflections and seated sightlines as well as lux. |
| Meeting room lighting | Table plane, faces, display wall, camera direction and meeting room scene record. | Table light does not prove board, screen or face visibility. |
| Print and storage lighting | Print bench, copier face, shelf label, reflected source and print storage record. | Utility tasks can fail inside a tidy whole-office average. |
| Reception lighting | Counter surface, guest face, sign or wall face, CRI/Ra, screen reflection and reception waiting record. | Reception records need horizontal and vertical visibility together. |
| Focus room or call booth lighting | Desk plane, face view, screen direction, small-room wall brightness and focus-room call-booth record. | Small rooms can pass a room estimate while faces, screens or wall contrast remain weak. |
| Office glare | Observer position, bright aperture, screen reflection path and dimming range. | Glare is a geometry and view issue, not a simple brightness correction. |
| Office lighting power | Zone boundary, connected watts, area, hours and active control state. | W/m2 should be compared only after the visual task is named. |
Office zone schedule
| Office zone | Assessed plane | Main risk | Record to keep |
|---|---|---|---|
| Open-plan desk bank | Desktop or document surface | A whole-floor average can hide weak rows, glare or screen reflections. | Desk group boundary, workplane height, screen direction, daylight row, control group and desk-row record. |
| Enclosed office | Desk plane plus visible walls | A small room can feel bright on the desk and dull around faces or shelves. | Room area, desk side, wall brightness note, switching or dimming mode and focus-room call-booth record. |
| Meeting room | Table plane, faces and display wall | Table lux alone may not support cameras, whiteboards or wall displays. | Table size, seating direction, display wall, camera direction and scene note. |
| Reception counter | Counter plane and visitor-facing vertical surfaces | Counter brightness can miss faces, forms and screen reflection. | Counter length, task surface, vertical note, CRI/Ra priority, screen angle and reception waiting record. |
| Circulation path | Floor or route plane | Over-lit paths can add load and contrast beside quieter desk areas. | Route width, door points, after-hours mode and separation from desk groups. |
| Print, utility or storage area | Bench, shelf face or floor route | A support room may need local task light rather than full office output. | Surface size, obstruction note, switching group and print storage record. |
An office schedule is useful because it separates the visual job before any arithmetic is done. If the desk bank and path share one ceiling group, note that constraint. If the fitout allows separate dimming or switching, keep the groups separate in the record.
Route the office question
| Office question | Primary page | Keep beside the record |
|---|---|---|
| Maintained light for a defined work zone | Workplace lighting calculator | Zone area, assessed plane, target basis, luminaire output, UF and MF. |
| Early room allowance for a small office | Room lighting calculator | Room size, ceiling height, mounting style and desk location. |
| Lumen allowance for a counter, desk group or wall | Lux to lumens calculator | Area must match the assessed surface, not the whole tenancy. |
| Existing output check | Lumens to lux calculator | Installed lumens, area and the gap between average lux and measured performance. |
| Assessed surface record | Task-plane records table | Keep desktop, meeting table, counter, shelf face and floor-route records separate. |
| Face, board or display visibility | Vertical illuminance | Treat cameras, whiteboards, signs and reception faces as vertical records, not desk lux. |
| Office task level context | Workplace lighting table | Task type, plane and project criteria kept outside any approval claim. |
| Broad Australian lux context | Australian lighting level planning table | Read as planning context beside AS/NZS 1680 material and the project brief. |
| Measured office readings | Lux meter reading record table | Assessed plane, meter position, daylight condition, fitting state and reading date. |
| Office control zoning | Lighting control record table | Daylight rows, meeting scenes, after-hours routes, dimming range and fallback condition. |
| Connected load per area | Lighting power density example table | W/m2 belongs beside the visual record, not in place of it. |
| Colour quality concern | CRI ratings table | People, printed material, finishes, samples and displays may need stronger colour rendering. |
| Colour appearance decision | Colour temperature table | CCT sets appearance; it does not replace illuminance, glare or control checks. |
Keep each calculation tied to one zone. A single average lux target across an office floor can make circulation unnecessarily bright while still leaving a reception counter, meeting display wall or internal desk row poorly served.
Desk, meeting and support areas
Desk lighting needs a defined work surface. Name the desktop or document area, then note the direction of screens and the row of luminaires relative to seated users. Bright fittings behind a worker may reflect in the screen. Bright fittings in front of the desk can create discomfort before the target illuminance is reached.
Meeting rooms need more than a table-plane number. Faces, displays, whiteboards and cameras create vertical tasks. If the room has presentation, video meeting and cleaning modes, record those modes separately from the base maintained-light estimate.
Reception and counter areas often mix task visibility with face visibility. A counter may need a local lumen allowance, a CRI/Ra note and a screen-reflection note. Print rooms, storage points and utility benches can also need local task records when labels, paper handling or shelves drive the visual task.
Task planes and vertical office records
The strongest office record says which surface is being judged before it says how many lumens are installed. A desk bank, meeting table, reception counter, wall display and shelf face can all be inside one fitout, but they do not share one assessed plane. The task-plane records table is the short route for naming that surface before a lighting result is compared.
Vertical visibility is a separate office issue. Meeting displays, whiteboards, reception faces, signage, shelving and camera views can look weak even when the horizontal desk plane is adequate. Where the question is a face, board, sign or wall, keep vertical illuminance beside the ordinary desk or room estimate.
| Office surface | Better record | Weak record |
|---|---|---|
| Desk bank | Desktop plane, screen direction, daylight row and control group. | Whole tenancy average used as proof of task visibility. |
| Meeting wall or display | Vertical target, seating direction, camera view and scene condition. | Table lux treated as board or camera evidence. |
| Reception counter | Counter task plane plus visitor-facing vertical surface. | Counter brightness with no face or screen-reflection note. |
| Store or print shelf | Shelf face, label height and obstruction note. | Floor reading used for vertical labels and storage faces. |
Glare and screen comfort checks
| Check | Why it matters in offices | Record response |
|---|---|---|
| Bright aperture in seated view | Direct discomfort can remain even when the desk average is acceptable. | Note observer location, fitting row, shielding, output and dimming range. |
| Reflected luminaire in screen | Reflections can reduce contrast on monitors and glossy devices. | Record screen direction, fitting row, window direction and likely reflection path. |
| Window beside or behind workstations | Daylight changes throughout the day and may create high contrast. | Note orientation, blinds, daylight row, separate control group and high-glare period. |
| Dark wall behind monitor | Strong contrast around the visual task can increase eye strain. | Add wall-brightness note or rebalance ambient and local light. |
| Display wall or camera direction | A room can have enough table light while faces or displays remain poor. | Record display wall, camera view, table light and scene setting. |
| Glossy counter or meeting table | Specular reflection can appear before the lux target is reached. | Note surface finish, luminaire angle and local dimming need. |
What is UGR in Lighting? explains discomfort glare and the limits of treating glare as a simple lux issue. For office planning, the key record is practical geometry: where people sit, what they look at, what bright surfaces they can see and which control group changes that view.
Daylight, controls, UF and MF
| Item | Office implication | Related page or record |
|---|---|---|
| Daylight row | Perimeter desks may be bright at some times while internal desks rely on electric light. | Window side, orientation, blind state and separate switching or dimming group. |
| Occupancy mode | After-hours movement may not need full desk output. | Sensor area, timeout, override and cleaning mode. |
| Measured illuminance | A desk, counter or floor-route reading needs the plane and operating condition. | Lux meter reading record table |
| Lighting zone | A desk row, meeting room, circulation route or after-hours group can carry a different control condition. | Lighting control record table |
| Load density | Connected load per square metre can compare zones only after the visual task is named. | Lighting power density example table |
| Utilisation factor | Room shape, reflectance, partitions and luminaire distribution change delivered light. | Utilisation factor table plus finish and obstruction note. |
| Maintenance factor | Dirt, ageing, access and diffuser condition affect maintained output. | Maintenance factor table plus cleaning and access assumption. |
| Colour temperature | Appearance should sit comfortably with daylight, finishes and adjacent rooms. | Colour temperature table |
| CRI/Ra | Colour rendering matters for people, print, fabrics, samples, signage and finishes. | What is CRI and CRI ratings table |
Daylight should be named, not silently subtracted. A window-side desk row may need glare control and dimming while the internal row still needs electric light. If daylight-linked control is part of the record, keep the row, sensor area and manual override visible beside the calculation.
UF and MF also need visible assumptions. Office partitions, dark finishes, acoustic rafts, services and high shelves can change delivered light after a neat lumen count has been prepared. A maintained-light estimate is stronger when those assumptions are written beside the count.

After a rounded fitting count is produced, read it as a zone estimate rather than a ceiling layout. Rows still need to respect desks, partitions, screens, diffusers, detectors, access panels, ceiling services and sightlines. Lower output may improve glare but increase the count. Higher output may reduce count but increase overshoot or discomfort. Record dimming as a control decision rather than a hidden correction.
For documented workplaces, keep the estimate beside the brief, luminaire data, control notes, Australian source material and any project-specific review. The public calculator record does not certify an office, approve emergency lighting, verify measured performance or replace formal workplace assessment. Add calculator scope when an office estimate is shared beyond early planning.
