The first is the aesthetic appeal of a building, an aspect particularly important in the illumination of retail environments. One study conducted by doctors at the Harvard School of Medicine stated that our circadian rhythms must be ‘reset on a daily basis in order to remain in synchrony with external environmental time’, and that ‘regular exposure to light and darkness’ was key to this. While the cost of installing windows, sliding glass doors or other glazing solutions might be initially higher than the average monthly power bill, once they’re installed, they don’t cost anything to run (unless you opt for a motorised or electrically powered option of course), and they light your interior spaces up even more effectively than artificial lighting. We designed and built the world’s first all-glass living environment, and sponsored Oxford University to undertake research on participants living in this glass home, deepening our understanding of the effects of daylight on human biology. Natural lighting, also known as daylighting, is a technique that efficiently brings natural light into your home using exterior glazing (windows, skylights, etc. Natural light, as it happens, is also a big factor in this: Natural light helps our body clock keep time: Our circadian rhythms are pretty important.

For most buildings incorporating daylighting, the overall energy savings range from 15 to 40 percent. The business case is clear: daylight promotes human health and potential. The importance of lighting. As the sun rises, our bodies innately understand that it’s time to reset the clock, and as the sun sets, the rhythm is maintained and we are prepared for rest and rejuvenation. Our circadian rhythms are pretty important. Now that’s smart. By providing a direct link to the dynamic and perpetually evolving patterns of outdoor illumination, daylighting helps create a visually stimulating and productive environment for building occupants, while reducing as much as one-third of total building energy costs. Darkness at night also helps in this regard. The Benefits of Natural Light for our Bodies and Minds: The human body is the product of thousands of years of evolution, and it is built to be exposed to natural light regularly. A study performed by Building Technology Innovations revealed that increased natural light makes a rental space look bigger and more open, resulting in people’s willingness to pay more. It might not seem obvious at first, but by choosing the right thermal glazing products, ‘solar gain’ (the heating effects of sunlight on an interior space) can be regulated and controlled. Keeping these things in mind as we progress as a society and as individuals could be the key to a better, brighter future. Architects should design buildings to maximise the use of daylighting and in many countries are rewarded for doing so by gaining points, e.g. No one likes getting up in the dark during the cold winter months, but getting enough natural light can actively combat negative psychological wellbeing. 1.
