Strict ratings for protection against dust (crucial in the UAE environment) and physical impact are required. 2. Lighting Infrastructure (Poles & Luminaires)
Adhering to the PR-402 standard is mandatory for any project in Abu Dhabi, including those in Al Ain and the Al Dhafra region. Failure to comply can result in project delays, non-approval by regulatory authorities, and necessary remedial work to replace faulty or non-compliant lighting fixtures.
The PR 402 manual is highly technical, bridging the gap between electrical engineering and urban design. It dictates specific parameters that must be calculated using lighting design software like DIALux or AGi32 before submitting project proposals. 1. Lighting Classes and Illuminance Levels
: Lighting classes (e.g., M2, M4) are assigned based on road type, with specific requirements for luminance (e.g., 1.0 to 1.5 cd/m²) and uniformity ratios . pr 402 abu dhabi lighting manual free
To successfully pass an audit or approval process using the PR 402 framework, ensure your submittal package includes:
: Adopted for specific urban routes requiring high visibility, with luminance levels of 1.3 cd/m² to 1.5 cd/m² (approx. 20–25 lux).
: High IK ratings to prevent vandalism and accidental damage. Strict ratings for protection against dust (crucial in
One of the primary mechanisms for enforcing the guide is the Sahel Rating System —Abu Dhabi's framework for creating accessible, sustainable, and inclusive buildings and communities. This system includes specific credits for "Lighting and display" (referenced as EQC.2.08 in the Public Realm Rating System and EQC.1.11 in the Building Rating System). To achieve these credits and obtain certification, project designs " shall adhere to mandatory requirements " and directly reference the PR-402_Lighting Manual.
: Designers must account for Lamp Lumen Depreciation (LLD) and Luminaire Dirt Depreciation (LDD) in their "Day-1" calculation outputs. Resources for Full Manual Access
