Energy management strategies around lighting have historically focused almost exclusively on cost and carbon reduction. The shift from fluorescent tubes to LEDs has delivered huge gains in efficiency, cutting energy use by up to 70%. But today, the conversation is evolving. Organisations are increasingly recognising that lighting is not just an overhead: it is a critical factor in employee wellbeing, productivity, and compliance with ESG goals…
Lighting and Human Performance
Research shows that poorly designed lighting can contribute to eye strain, fatigue, and reduced concentration. Conversely, lighting schemes aligned with human circadian rhythms can boost alertness, support sleep quality, and improve overall wellbeing.
Modern commercial lighting now incorporates tunable white technology, which adjusts colour temperature and intensity throughout the day. Cooler, brighter tones in the morning promote focus, while warmer tones in the afternoon help reduce strain. For offices, hospitals, and schools, this human-centric approach directly enhances performance and comfort.
Balancing Efficiency with Wellbeing
The challenge for energy managers is balancing these human factors with sustainability and cost objectives. Fortunately, the latest generation of LED and OLED technologies combine ultra-low energy consumption with flexible, programmable outputs, making it possible to optimise for both efficiency and wellbeing.
By integrating with smart control systems, lighting can respond dynamically to occupancy and natural daylight levels. This reduces unnecessary consumption while ensuring spaces remain consistently well lit for the tasks being performed.
Health, Safety and Compliance
Lighting is also a compliance issue. UK workplace regulations require sufficient, appropriate lighting for safe working conditions. In sectors such as manufacturing, warehousing, and healthcare, inadequate lighting can increase accident risk.
Digital lighting management platforms allow organisations to monitor lux levels across facilities and ensure compliance with Health and Safety Executive (HSE) standards, while also providing an audit trail for inspections.
The ESG Imperative
With ESG reporting now central to board-level agendas, lighting projects are being reframed as part of social sustainability as well as environmental. Demonstrating improvements in employee wellbeing through lighting design, alongside measurable reductions in energy and carbon, supports both “S” and “E” outcomes in ESG frameworks.
Looking Ahead
Commercial lighting strategies must go beyond energy savings. By embracing human-centric design, smart controls, and compliance monitoring, energy managers can deliver workplaces that are healthier, more productive, and more sustainable.
The most successful organisations will be those that treat lighting not just as a cost to be minimised, but as a tool to enhance both people and performance.
