Achieving Compliance with EN 12464-1 in Lighting

EN 12464-1 is a European standard that specifies the lighting requirements for indoor workplaces to ensure visual comfort and performance. Compliance with this standard involves several key steps and considerations:

Key Requirements of EN 12464-1

Illuminance Levels (Lux)

Definition: Lux is the unit of measurement for illuminance, indicating the amount of light per square meter.

Requirement: The standard specifies minimum lux levels for different types of workspaces. For example, general office areas typically require at least 500 lux

Unified Glare Rating (UGR)

Definition: UGR measures the discomfort glare caused by lighting fixtures.

Requirement: The standard sets maximum UGR values to ensure visual comfort. For office environments, a UGR of 19 or lower is recommended

Colour Rendering Index (CRI)

Definition: CRI measures how accurately a light source reveals the colours of objects compared to natural light.

Requirement: The standard requires a minimum CRI of 80 for most indoor workspaces to ensure accurate colour representation

Lighting Uniformity

Definition: Uniformity refers to the even distribution of light across a workspace.

Requirement: The standard specifies minimum uniformity ratios to avoid areas of excessive brightness or darkness, which can cause visual discomfort

Daylight Integration

Definition: Incorporating natural light into the lighting design.

Requirement: The standard encourages the use of daylight to reduce energy consumption and enhance occupant well-being

Steps to Achieve Compliance

Assessment and Planning

1. • Conduct a thorough assessment of the workspace to determine the specific lighting needs based on the tasks performed and the layout of the area.

1. • Develop a lighting plan that meets the minimum requirements for lux levels, UGR, CRI, and uniformity.

Selection of Lighting Fixtures

1. • Choose lighting fixtures that meet the specified criteria for illuminance, glare control, and colour rendering.

1. • Consider fixtures with adjustable settings to allow for flexibility in achieving the desired lighting conditions.

Installation and Adjustment

1. • Install the lighting fixtures according to the design plan, ensuring proper placement and alignment to achieve uniform lighting distribution.

1. • Make necessary adjustments to the lighting settings to meet the required lux levels and UGR values.

Performance Verification

1. • Conduct on-site measurements to verify that the installed lighting meets the specified requirements for illuminance, glare, and colour rendering.

1. • Use light meters and other tools to measure lux levels, UGR, and CRI in different areas of the workspace

Documentation and Reporting

1. • Maintain detailed records of the lighting design, installation, and performance verification processes.

1. • Prepare a compliance report that documents how the lighting system meets the EN 12464-1 requirements.
