How to get more and better daylight in your home

REQUEST A QUOTE

Daylight is incredibly important for your health and well-being. Research shows that the light strengthens your immune system, adjusts your circadian rhythm and affects your sleep quality. Daylight also gives energy and happiness – to such a degree that many people experience tiredness and sadness or even depression in the dark winter months.

Daylight also helps heating up your home and reduces the necessity of artificial lighting. That way you get savings on your heat bill and your electricity bill. And with plenty of daylight your home will feel bigger and more spacious.

There are several ways you can let in more daylight.
 
» Choose bigger windows

Bigger windows let more daylight into the house – that should be no revelation. But actually it’s not that simple.

Tall windows, or windows in a higher position, distribute the light evenly and far into the room. Low windows, or low positioned windows, concentrate the light around the window and give a more varied distribution of the light.

However, about four to five meters into your home it no longer matters if the window is tall or low. So choosing tall glass sections doesn’t necessarily mean that the light will travel all the way into the inner rooms.

The size of the windows also affects how comfortable the light is. The bigger the windows, the weaker and softer the shadows become. The smaller the windows, the harder and more contrasted shadows. A big contrast in luminosity can be uncomfortable and cause glare.
 
» Draw the light further into your home

If your house is very deep, it can be difficult to get enough daylight all the way into the deepest rooms. Oftentimes it will be necessary to turn on the lights in the innermost parts of the house, even on the brightest summer day, and this increases your energy consumption.
However, there are ways to draw the daylight further into your home:

» Replace full partitions with half partitions or room dividers where possible;
» Alternatively, you can install high-sitting glass sections in the partitions to allow the light to wander from illuminated rooms to darker rooms;
» Skylights might also be an option, depending on your house.
 
» Position the windows strategically

If you are building a new house or refurbishing your old one, you should think of how the windows are positioned towards the four corners of the world. The positioning decides how much daylight is let into your house, and what time of the day and year, you get the biggest inflow of light:

» South facing windows receive the biggest inflow of sunlight;
» East facing and west facing receive about the same inflow of light;
» North facing windows don’t receive direct sunlight.

The best light is achieved if the room has windows facing towards two or more corners of the world.

Big, south facing windows also take full advantage of the sunlight and heat, which could give you significant savings on energy for heat and artificial lighting.
 
» Choose the window models that let in the most daylight

Windows in themselves can have a huge impact on how much light you will get in your home. Because of this, it’s a good idea to go for a window model that is designed to let in as much daylight as possible.

Windows with slim frames (profiles) – such as the VELFAC 200 – have a bigger area of glass than other windows and thus give a bigger influx of light.

If you are looking for windows with grilles, slim grilles will let in more daylight.
