Office Lighting Design

Standards

General lighting — 300-500 lx at workstations; UGR ≤ 19; CRI ≥ 80. For detailed work — 500 lx with local lighting.

Luminaire selection

LED panels 36-60 W (4000-5000 lm) for Armstrong ceilings. Track for accents. Emergency — with batteries, 1-3 hours.

Placement

Rows along the windows with the spacing ratio ≤ 1.5 of the height. Near the monitor — parallel to avoid glare on the screen.

Control

Scenes, daylight sensors near the windows, presence sensors in utility rooms — savings of 30-50%.

Emergency lighting

Routes and exits: 1-3 hours of battery; the scheme with pictograms is mandatory for offices from 50 people.

Why design

The lumen method in GorkyCAD counts the fixtures and checks LPD — the office passes the audit without rework.
