Electrical Survey and Design

As an essential component of lighting design, emergency lighting ensures occupant safety by providing illumination in the event of a power failure. In the UK, this is a legal requirement and must comply with current regulations, the primary standard for compliance is BS 5266. We can assist in the design of UK law-compliant emergency lighting systems.

The BS 5266 standard serves as a comprehensive guide for the design of emergency lighting systems. The process begins with an in-depth lighting consultation, which is followed by a thorough risk assessment aimed at verifying escape routes and identifying critical safety features that need illumination, including:

• The precise locations of fire alarm call points to ensure swift response in case of emergencies.
• Strategic placements of fire-fighting equipment, allowing for immediate access when every second counts.
• The positioning of escape route lighting, along with essential safety signs and indicators, to guide individuals safely to exits.
• Clear requirements for emergency escape lighting, designed to function effectively during power outages.
• The locations of lifts to facilitate movement in multi-story buildings during emergencies.
• The integration of moving stairways and walkways to maintain clear pathways for evacuation.
• Designated areas in covered car parks to ensure visibility and safety for those seeking shelter.
• Evaluation of sections that require standby lighting to maintain visibility during critical moments.
• Identification of areas for the installation of central power supply units to support the emergency lighting system.
• Assessment of high-risk task areas that necessitate dedicated emergency lighting solutions.
• A detailed analysis of areas that require emergency safety lighting to enhance overall safety.

Once we have clearly established where emergency lighting is required and the positions of essential safety equipment, we can proceed with the intricate task of detailed lighting design. This entails several key steps:

• Strategically positioning emergency (EM) luminaires on the design plan to create a cohesive lighting strategy.
• Taking into account the mounting height of luminaires to minimize glare, as well as ensuring appropriate spacing between these fixtures for optimal effectiveness.
• Determining the required duration of the emergency lighting—either 1 hour or 3 hours—to match the needs of the specific environment.
• Selecting appropriate luminaires and obtaining comprehensive photometric data, including critical metrics such as spacing tables, light output, and distribution patterns.
• Calculating the necessary illuminance levels to ensure safety and visibility throughout the designated areas.
• Conducting checks for uniformity in lighting to promote a consistent and reassuring environment during emergencies.
