Skylights can play a significant role in promoting environmental health, building health and building biology. Skylights are windows installed in the roof of a building that allow natural light to enter the interior space. This can help reduce the need for artificial lighting and improve indoor air quality by reducing the concentration of pollutants such as volatile organic compounds (VOCs) that can be emitted from artificial lighting. Skylights can also help regulate indoor temperatures by allowing heat to escape during the summer and trapping heat during the winter. By choosing skylights that are energy-efficient, non-toxic and have a minimal impact on the environment, building owners can help promote a healthier indoor environment for building occupants
