5 Top Benefits of Natural Daylight in Building Designs

Although the sun’s rays can be harmful to skin, exposure to daylight can boost health, well being; and mood. Exposure to sunlight during the day has proven to be beneficial, especially in commercial and retail buildings. Having access to natural light is part of our survival and natural cycles so it’s essential that we have access to it for at least a couple of hours a day. When taking on any building design, you should always think about the benefits for the occupants within. Here are just a few of the benefits of natural sunlight in any building.

Energy saving

Building with an abundance of natural sunlight brings reduced energy bills because artificial lighting is not needed as much. This makes a rooflight an environmentally friendly way to design a building and provide the occupants within with a number of benefits. In the colder months when there are fewer hours of daylight, a building with lots of natural light allows those within to make the most of the light that there is, and in the summer, they might never need to turn on the heating or internal lights.

More sleep

Studies have shown that workers with more exposure to light during the day at work sleep much better and for longer. This is all due to the amount of serotonin produced throughout the day as a result of being exposed to a larger amount of sunlight. It helps our bodies know when it’s time to be awake and when it’s time to go to sleep. Those who are not exposed to daylight during the day report trouble sleeping and lack of refreshing sleep.

Higher productivity

Workers who get more sleep and are in a better mood are, naturally, more alert and productive at work. Daylight helps to reduce eye strain and increase visual performance which allows workers to perform tasks for longer and more accurately.

Increased sales

Increased sunlight within a retail environment has also proven to increase the amount that shoppers are willing to spend. Those who are exposed to sunlight are happier, in a better mood, are more comfortable, and will therefore spend more, and more frequently. Sunlight also makes colours appear brighter and more vivid so goods appear more attractive to customers and encourages them to spend more time in those areas.


In addition to retail and commercial settings, natural sunlight has also proven to be beneficial in educational settings too. Research has shown an improvement in student performance and attendance in children who were exposed to more daylight at school. Their concentration was better and behaviour improved.

At Xtralite, we provide a range of services to help you implement and design the perfect rooflight for any building and maximise the natural sunlight with the design.
