The importance of natural light in a building

We all know the amount of daylight we are exposed to every day is fundamental for our wellbeing and it improves our creativity and productivity. Unfortunately, because we spend most of our time inside of a building, no matter if it is a warehouse, an office, or our home, our intake of natural light is less than 1% of what we get when we go out on a sunny day, and the worst is that we have this deficiency since our school years, because we spend many hours a day closed in a classroom.

Designers tried to invert this trend, creating new styles that increase the quantity of natural light entering in a room, and the most recent design trends reflect this intent, and it is worth to know why all our efforts are going towards this way, so here are a few reasons why natural light is important in a building.

Natural light improves our health

As we already said, natural light is good for our wellbeing. According to the blog NetDoctor, the ideal amount of light that would help our health is about 100,000 lux, provided by the sunlight. Basically, going out for a walk during your lunch break would really help. When we are at work and our children are at school, we get about 300-500 lux, which is like being closed in a box.

During the past decades, we thought artificial light would have been a good replacement for natural light, so the industry did not mind too much about it, especially with the mass construction techniques widely used in this sector. Now that we are realising it is not really the same thing, we are trying to fix this issue.

Natural light saves energy

With the right combination of exposure to daylight and colour palette, the room will be bright enough to allow you to switch off all the lights, even in an average cloudy day in Britain, a window can guarantee from at least eight hours of light a day in December and January, to 16 hours a day in June and July. This is one of the main reasons why our electricity bill during Summer is cheaper than during Winter, but there is more: with the presence of a window, there is no need of an extractor fan, unless there is heavy rain outside, so ventilation systems are used less than before, and their life is longer.

In the last twenty years the number of rooms without a source of natural light in a house or commercial building constantly decreased, and now architects strive to make sure there is at least a window in every room.

Natural light prevents mould

You may think this is an old cliche, but it is the truth: mould expands when the warm and humid air meets a cold and moist surface. Circumstances particularly frequent when the room has no windows and the lighting and ventilation are inadequate, however, if the room is exposed to a sufficient quantity of natural light, there will be no favourable condition for the development of moisture, which supports the growth of the spores.

Anti moisture paint can help, but natural light is the real problem solver.

Natural light is the future

We can only benefit from natural light, and we are sure the buildings of the future will take this consideration into account, and so do we. Natural light makes us feel happy, productive, and healthy, on top of being good for the planet, and the new generation of architects is aware of that.
