The Benefits of Natural Light & Ventilation:
A breath of fresh air is a simple pleasure we all appreciate – and there is no reason why we should not be able to enjoy free-flowing air indoors too. The benefits of natural light and ventilation include a range of health benefits, boosting the interior aesthetics and energy efficiency of your building.
Health & Well-Being
It’s vital for our health that our homes are well lit. Lack of light can make us feel sleepy and depressed, but exposure to bright light reverses the process and triggers dramatic positive responses, due to increased production of the natural chemical serotonin.
The level of natural light in your rooms can really affect your mood. Those blessed rays, filled with sunlight and vitamin D make you feel positive. So, it’s natural that bright rooms make us feel happier, more alive and vibrant.
Indoor air quality can affect how we feel and how we work. The benefits of having good levels of air in homes and offices include better health, increased concentration, improved pleasant aromas, not to mention it makes us feel great!
Natural light enhances ability to concentrate over longer periods resulting in greater productivity. It Aids capacity for knowledge retention and therefore improved learning ability and bestows a sense of well-being.
Design & Interiors
Natural light has the ability to make the space look extra spacious. It can impact on all aspects of interior design, make a room come to life and connect it to the outside. Natural light improves space utilisation by bringing natural light to under-lit areas
On more pragmatic levels, fresh air ventilation helps to prevent incidences of mildew and damp, so houses stay fresh and their inhabitants are happier.
Inside your home, use clear glass, frosted glass or mirrored doors that separate areas, but let in light.
It is important to let hot air escape from rooms and if there is a window, most of us would open it to let air circulate. However, if the room in question is windowless or below ground a different solution is needed. So, when designing rooms within buildings, especially core spaces, basements and windowless areas, ensuring there is good fresh air ventilation is equally as important as high levels of natural light.
Lighting can account for up to 25% of a buildings energy costs. Using natural lighting can lead to substantial savings in your energy bills. In the tropical climates care has to be taken not to provide too much natural light since it comes along with the heat and there has to be considerable amount of cross ventilation to avoid heat accumulation.
Natural light is not without its issues. These include glare, overheating, variability and privacy issues, since transparent materials must be used. Care has to be taken to increase the positive aspects of using natural light in buildings and decrease the negative.
