Besides the ongoing optimization of glass coatings for sustainable and green building designs, the façade and glass industry must start focussing more on human needs leading to a more human centric design of glass coatings. Our modern solar control coatings feature highly spectral selective transmittances to reduce solar heat gain through the glass and consequent reduction of the building’s cooling loads. This spectral selectivity causes that the building’s occupants get a more or less “filtered” light and solar spectrum transmitted through the glass. This transmitted spectrum is, to a certain extent, only a fraction of the natural solar spectrum that we would be exposed to outdoors – especially for the modern triple silver and quad silver solar control coatings referring to the long wave infrared spectrum above 780nm wavelength. It is currently unknown how this affects the human wellbeing, opposite to the blue range spectrum around 490nm wavelength where recent research unveiled the importance for the human circadian rhythm. Besides the traditional light transmittance of glass, a new melanopic transmission factor of glass with focus on the wavelength important for the human’s circadian rhythm is discussed.
