Lighting today is no longer just about visibility—it’s about creating intelligent, sustainable, and human-centric spaces. At the heart of this evolution is the EN 12464 standard, which defines the requirements for lighting workplaces to ensure visual comfort, safety, and occupant wellbeing.

At EVIO, we are committed to helping our clients implement smarter lighting strategies that align with these global benchmarks, ensuring every project is efficient, compliant, and future-ready.

The Core Focus: EN 12464-1 for Indoor Workplaces

The cornerstone of lighting design remains the EN 12464-1 standard. While the lighting landscape evolves, the core principles of the indoor standard continue to guide how we illuminate offices, healthcare facilities, retail spaces, and schools.

The focus remains on creating environments that enhance visual performance while protecting the health of the occupants. The primary focus areas of the standard include:

• Maintained Illuminance: Ensuring that spaces remain properly lit throughout a building’s lifecycle by accounting for equipment ageing and usage patterns.
• Quality of Light: Managing glare, flicker, and stroboscopic effects to reduce eye strain and fatigue.
• Intelligent Controls: The critical role of dynamic lighting solutions that adapt to daylight and occupancy.
• Task Flexibility: Prioritising lighting that can be adjusted to suit various tasks and individual user preferences.

New for 2024: Expanding to Outdoor Workplaces (EN 12464-2)

In 2024, the scope of professional lighting design expanded with the update of the sister standard: EN 12464-2:2024 – Lighting of Workplaces, Part 2: Outdoor Workplaces.

Modern building design no longer treats the interior and exterior as separate entities. This updated standard covers various outdoor working areas—many of which are adjacent to buildings and must be designed in conjunction with indoor spaces. Whether it is a logistics hub, a campus walkway, or a loading zone, the standard ensures that the transition between indoor and outdoor environments is safe, secure, and visually consistent.

Partnering for Smarter Buildings

At EVIO, we work with Helvar, a global leader in lighting control and automation solutions, to bring these cutting-edge technologies to our projects. By combining EVIO’s local expertise with Helvar’s world-class innovation, we deliver flexible, future-proof lighting systems that meet both regulatory requirements and evolving user expectations.

The Helvar Rules of Right Light

While the EN standards provide the necessary regulatory framework, achieving truly “human-centric” lighting requires a deeper level of design expertise. To bridge the gap between compliance and wellbeing, Helvar has developed the Rules of Right Light.

This framework helps specifiers and designers go beyond the minimum requirements. It provides a roadmap for creating lighting that supports the biological and emotional needs of people—balancing energy efficiency with the “right” light at the “right” time and in the “right” place.
