Apartment common area map
Apartment lighting is split between private rooms and shared areas. Shared corridors, lift lobbies, mail rooms, bin rooms, storage cages, stairs, entries, car park links and outdoor-adjacent paths need records that are separate from a unit living room or bedroom. The first question is whether the space is an interior circulation zone, a task surface, an exposed entry or an emergency-lighting boundary.
The room lighting calculator is the main route for a simple lobby, corridor or shared room estimate. The downlight spacing calculator supports ceiling set-out where fitting spacing and wall offsets matter. For a narrow counter, mail area or signage surface, the lux to lumens calculator keeps that allowance separate from the general area.
Route the shared-area question
| Apartment area question | Primary page | Keep beside the record |
|---|---|---|
| Corridor or lobby estimate | Room lighting calculator | Zone area, target plane, luminaire output, UF and MF. |
| Downlight spacing in a hallway | Downlight spacing calculator | Effective height, beam angle, wall offsets and dark gaps. |
| Mail bench or noticeboard allowance | Lux to lumens calculator | Surface size, vertical visibility and local shadows. |
| Assessed plane record | Task-plane records table | Separate corridor floor, mail bench, lift-door face, sign, shelf and threshold records. |
| Ceiling and bulkhead effect | Ceiling-height lighting effects table | Keep low ceilings, bulkheads, wall lights and effective height visible before spacing is accepted. |
| Beam overlap and dark-gap note | Beam angle coverage table | Corridor, lobby, stair and entry geometry checked before layout assumptions spread. |
| Entry or exterior-adjacent fitting | IP ratings table | Exposure, rating, mounting orientation and location. |
| Emergency lighting boundary | Emergency lighting standards table | Ordinary lighting record kept separate from emergency records. |
| Colour and comfort | Colour temperature table | CCT, finishes, faces, glare and night transition. |
| Field reading or maintenance check | Lux meter reading records | Reading point, operating mode, sensor state and surface condition. |
Search intent split for shared areas
Apartment common-area searches often compress several building records into one phrase. Split the ordinary-lighting estimate from emergency, exposure, sensor and maintenance records before comparing results.
| Search phrasing | Stronger lighting record | Why it should stay separate |
|---|---|---|
| Corridor lighting | Continuous floor route, door recesses, wall offsets, dark-gap note and night mode. | A corridor is not the same calculation as a lift lobby or mail bench. |
| Lobby lighting | Floor route, face visibility, reflective lift doors, signage and daylight condition. | Lobby comfort depends on vertical surfaces as well as the floor. |
| Mail room lighting | Bench plane, label face, parcel shelf, local shadows, switching position and mailroom parcel record. | Mail tasks can fail inside a broad lobby average. |
| Lift lobby lighting | Call-panel face, waiting position, door threshold, reflective surface and lift lobby record. | Lift lobbies need face and threshold notes beyond a corridor floor value. |
| Stair or threshold lighting | Floor or landing plane, contrast, transition condition and emergency boundary. | Ordinary lighting and emergency records must remain separate. |
| Bin room or exposed entry lighting | Task surface, obstruction, cleaning exposure, enclosure note, measured state and bin room record. | IP and exposure language should not be hidden inside lux arithmetic. |
| Sensor or timer lighting | Control state, after-hours level, operating hours and connected load. | Energy and observed route clarity depend on the active mode. |
Assessed planes and zone splits
Apartment common areas work best as small records. A corridor floor, lift lobby, mail bench, stair landing and entry threshold can sit within a short walking path while each needs a different lighting note. The assessed plane should be named before the calculation route is chosen.
| Assessed surface | Record as | Calculator or table link |
|---|---|---|
| Corridor floor | Continuous circulation zone with dark-gap note. | Room lighting calculator |
| Lift lobby floor and wall faces | Room estimate with face visibility and signage. | Apartment lift lobby records |
| Mail bench or parcel shelf | Local task surface, slot face and parcel label kept out of the corridor average. | Apartment mailroom and parcel records |
| Bin room labels and floor route | Local floor, label and cleaning-edge records kept separate from the corridor average. | Apartment bin room lighting records |
| Stair landing or threshold | Transition area with emergency boundary note. | Emergency lighting standards table |
| Entry canopy or bin-room edge | Exterior-adjacent zone with enclosure note. | IP ratings table |
Task, vertical and height records
Shared-area questions often sound like corridor or lobby lighting, but the record may be a task surface or vertical face. A mail bench, parcel shelf, noticeboard, lift sign, apartment number, bin-room label or entry intercom should not be hidden inside a corridor floor average. The task-plane records table names the surface before the room or spacing result is compared.
Lift lobbies and entries also need vertical visibility. Faces, signs, reflective lift doors and intercom panels can read differently from the floor route. Where the surface is vertical, keep vertical illuminance beside the ordinary room estimate and record the viewing direction.
| Shared-area surface | Better record | Weak record |
|---|---|---|
| Long corridor floor | Continuous route plane, wall offsets, doors and night mode. | One lobby average applied to every corridor branch. |
| Mail bench or noticeboard | Local task lighting layer with shadows and vertical labels. | Floor lux treated as label or parcel visibility. |
| Lift lobby faces and signs | Vertical face, sign height, reflective doors and glare direction. | Floor reading used for face visibility. |
| Low bulkhead or high entry void | Ceiling height, effective height, beam footprint and direct-view glare. | Standard corridor spacing reused after the ceiling condition changes. |
Interior shared zones
Shared interior spaces need enough light for movement, recognition and simple tasks without turning every corridor into an over-lit room. A lobby may need face visibility, wall brightness and a welcoming appearance. A corridor may need consistent route clarity. A mail area may need a task-surface note. A storage room may need shadow control around shelves and doors.
The Australian lighting level planning table gives planning context, while the lighting units table keeps lux, lumens, UF and MF language clear. If an estimate changes from one common area to another, keep a separate record rather than averaging unrelated spaces.
| Shared area | Calculation focus | Secondary check |
|---|---|---|
| Lift lobby | Room estimate and face visibility. | Wall brightness, signage and glare at doors. |
| Corridor | Continuous route and floor visibility. | Dark gaps, turns, door recesses and night use. |
| Mail room | Task surface for labels and parcels. | Shadows, vertical surface and local contrast. |
| Storage room | Shelf and floor visibility. | Obstructions, doors and switch location. |
| Entry canopy | Exterior-adjacent floor and threshold. | Exposure, step contrast and spill direction. |
Mounting, exposure and controls
Mounting conditions are often the reason shared-area estimates drift away from the first arithmetic pass. Low ceilings, wall lights, bulkheads, lift doors, security cameras, signs and fire equipment can all affect spacing and useful light. The record should keep the fitting position and obstruction note beside the number.
| Condition | Lighting note to keep | Why it matters |
|---|---|---|
| Long corridor with doors | Spacing, wall offsets and door recesses. | Even route visibility can be more important than the average. |
| Lift lobby | Luminaire position near reflective doors. | Glare and face visibility both affect comfort. |
| Mail or parcel area | Local task surface and vertical labels. | Sorting tasks can be hidden inside a general lobby estimate. |
| Bin room or utility room | Exposure, cleaning water, obstruction note and bin room record. | Enclosure language should be separate from lux arithmetic. |
| Timed or sensor control | Operating mode and after-hours condition. | A dimmed mode can change the observed route clarity. |
For downlight-heavy corridors, keep downlight spacing and beam angle coverage close to the room estimate. For exposed thresholds, read IP44 vs IP65 with the IP ratings table so the enclosure note is clear without turning this page into installation advice.
Read the complete fitting label beside the exposure note. The luminaire markings table keeps lumens, watts, IP rating, CCT, CRI/Ra, input rating and dimming notes from being collapsed into one fixture description.
Emergency and exposure boundaries
Apartment common areas often sit close to emergency-lighting and electrical-installation questions. This page does not approve emergency lighting, exit signs, wiring, switch location or compliance outcomes. Keep ordinary lighting estimates separate from emergency lighting and exit sign records.
For exposed entries, bin rooms, car park links or outdoor paths, read IP ratings and IP44 vs IP65 as enclosure-language pages. They do not decide installation details. They keep the exposure term visible so the room or spacing estimate does not carry more meaning than it should.
Where the shared route connects to a car park or outdoor path, keep the car park sector page and outdoor sector page beside the ordinary lighting estimate. Those pages keep vehicle movement, spill light, exterior exposure and public-space boundaries out of the lobby or corridor calculation.
Shared-area record path
Name the common area, separate ordinary lighting from emergency lighting, then choose the calculation route that owns the number. Keep area, target plane, luminaire output, watts, UF, MF, spacing, colour appearance, exposure and emergency boundary notes together. The result is a planning record for conversation and comparison, not a replacement for the project documentation used by the building team.
| Record item | Apartment-specific detail |
|---|---|
| Area name | Lift lobby, corridor branch, mail room, storage room, stair landing, entry canopy or bin room. |
| Assessed plane | Floor route, bench surface, vertical label, wall sign, threshold or shelf face. |
| Geometry | Area, ceiling height, corridor length, wall offset and obstruction note. |
| Calculation inputs | Luminaire output, UF, MF, beam angle, spacing and target table reference. |
| Quality notes | CCT, glare at reflective doors, sensor mode, daylight, exposure and measured readings. |
| Load notes | Input watts, operating hours, sensor state and zone area kept separate from route visibility. |
| Review boundary | Ordinary lighting, emergency lighting and electrical installation records kept as separate documents. |
Supporting apartment checks
Shared apartment areas often change character through the day. A lobby may receive daylight near the entry but not near lifts. A corridor may feel acceptable when doors are open and flat when all doors are closed. A storage room may be used briefly but still needs clear shelf and floor visibility. Record those local conditions before comparing one common area with another.
Control grouping is also worth naming. A lift lobby, corridor branch, stair landing and car park link may operate on different schedules. If a sensor, timer or after-hours mode is expected, keep the operating note beside the lighting estimate. For exposed entries and car park links, keep the IP note separate from the lux or spacing note. That separation helps the record stay readable when building management, strata committees or design teams discuss the same area later.
Use lighting control records for sensor, timer and after-hours modes, and lighting power density examples when watts, zone area and operating hours need to stay together. Those records explain operation and load; they do not replace the lux, spacing, emergency or exposure checks.
Where a shared area links directly to a car park, outdoor path or emergency egress route, keep a separate line for that adjacent condition. A common-area estimate should show the ordinary-lighting path, the emergency record and any exposure note without implying that one page approves all three.
