Designing to BS 5266-1: Visual Emergency Lighting

Under the Regulatory Reform (Fire Safety) Order 2005, employers and building owners have a statutory duty to provide adequate emergency escape lighting. This 2D visual tool automates the core spatial requirements defined by BS 5266-1 to specify the placement, overlapping coverage radii, and hardware requirements for your luminaires.

The Two-Step Placement Rule

• 1. Points of Emphasis (PoE): Before attempting to light the center of the room, BS 5266 dictates that a specific emergency luminaire must be placed within 2 metres of every exit door, intersection, change of direction, or fire equipment. Our engine plots these critical nodes first (shown adjacent to the doors).
• 2. Open Area (Anti-Panic): Once the exits are secured, any open space larger than 60m² requires a minimum of 0.5 lux. The simulator calculates the coverage radius of your chosen fixture based on the ceiling height, and generates a grid to ensure these photometric circles overlap seamlessly without dark spots.

Integrated vs. Standalone

A common mistake in commercial quoting is over-specifying emergency equipment. By selecting Integrated Maintained, the simulator draws the background grid of everyday office lighting panels (e.g., 600x600mm panels spaced every 2.4m). It then mathematically highlights only the specific panels that must be upgraded with a 3-hour emergency conversion pack.

Selecting Standalone clears the everyday grid and shows you exactly where to drill the ceiling to install dedicated emergency bulkheads or mini-spots.
