The objective of this study is to investigate the health impact of two kinds of window glass on healthy individuals in a public housing in Denmark. Since the invention of the insulating glass units (IGUs) in the 1970s, a lot of innovative effort and talent has been put into optimizing the performance of window glass as climate screens. Unfortunately these efforts have served only one purpose; energy. A development which seems to continue in the build environment in the near future, and seems to be the most rational choice, if we do not consider other parameters, such as health. Spending on average 90 % of our time in the indoor environment, the quality of the window glass plays an important and yet overlooked role for our circadian rhythm, sleep, mood, wakefulness and levels of vitamin D. Recent discoveries about the missing piece in the lighting puzzle, the non-visual IpRGCs, put emphasis on natural daylight and its beneficial effects as an efficient Zeitgeber, however until now studies have focused on artificial lighting and not daylight
