There’s a reason why desks near windows are coveted office real estate. We’re biologically hardwired to prefer places with lots of light. Monitoring light intensity ensures we know there’s enough light to work effectively, and has the potential for huge energy savings.

The right light levels

Not too bright, not too dull – what level of illumination is ideal for office lighting?  The recommended range for workplace task lighting is between 300 and 500 lux. Lux is a standardised unit of measurement of light level intensity, which is commonly referred to as "illuminance" or "illumination".

Light and wellbeing at work

Optimization of natural light in an office significantly improves health and wellness among workers. In fact, Cornell University research revealed that workers in daylight office environments reported a 51% drop in eyestrain complaints, a 63% drop in headaches, and a 56% reduction in drowsiness. 

Studies have also revealed that employees who don’t get enough sunlight at work experience more sleep, energy, and health problems. It’s no surprise then that a Harvard Business Review study showed that employees value sunlight and outdoor views over every other office perk.

Save energy 

Office buildings consume a substantial amount of energy and lighting is one the single biggest consumers. Monitoring light levels over time, can help you understand if energy is being spent unnecessarily on lighting, for example, if there’s enough natural light in the room or lights are being left on accidentally. By continuously monitoring your light levels, you could identify trends and decrease your electricity consumption.
