Lighting is an all-year energy consumption in most offices and increasingly intelligent lighting systems are in place that can optimally control lighting levels. However, it is rare that systems are used to their full capabilities and rarer still that organisations are aware of the secondary benefits.
Using the secondary benefits of careful lighting control can be a driver to energy reduction. Favouring and maximising natural daylight in office spaces can not only lead to office workers being more productive, but also improving well being.
What are the 5 key benefits to maximising natural daylight?
- Increased alertness: Exposure to natural light helps regulate the body’s internal clock and promotes wakefulness. This can lead to improved focus and alertness among office workers.
- Mood enhancement: Natural light has a positive impact on mood and can reduce feelings of stress and anxiety. A pleasant working environment with ample daylight can contribute to a more positive and productive mindset.
- Better sleep quality: Exposure to natural light during the day helps regulate the body’s sleep-wake cycle. When office workers have better sleep quality, they are more likely to be well-rested and perform better during working hours.
- Improved cognitive performance: Studies have shown that natural light can enhance cognitive function, including memory, attention, and problem-solving skills. This can lead to higher productivity and efficiency in completing tasks.
- Eye health: Adequate natural light can reduce eye strain and the risk of developing certain eye conditions associated with poor lighting, such as eyestrain, dry eyes, and headaches.
To maximize the benefits of natural light, office spaces are often already designed with large windows. However, many windows are often obscured by blinds at times when neither heat or glare needs to be reduced. Having a strategy of when to use the blinds and when not to, can enhance the level of natural daylight and reduce the need for artificial light.
Setting intelligent lighting system in zones away from sources of natural light can dim lighting when light levels are adequate, and using light-coloured walls and reflective surfaces can help distribute natural light throughout the space.
