The 16th May 2019 marked the second UNESCO International Day of Light
. Celebrated across the world by many different sectors of society, the global annual initiative focuses on the important role light plays in science, culture, art, education, construction, and in fields as diverse as medicine, communications, and energy.
Light touches the daily lives of everybody. Appreciating and harnessing its power is fundamental to our development as a society. It not only helps us to grow and innovate but natural light is key to helping us achieve greater energy efficiency in our buildings, creating a more sustainable future for all. Natural light is the most sustainable lighting option available; it is also a free renewable resource.
Daylighting refers to the deliberate placement of windows, skylights, and other openings in buildings to let in as much natural light as possible. People thrive on natural daylight, and yet we have constructed a world in which we spend much of our time – whether at home, the workplace, or school – in spaces where our access to it is restricted. However, being inside does not mean having to lose out on daylight, with this point increasingly reflected in building designs utilising daylighting products to enhance natural light indoors.
