Lighting requirements are primarily dictated by the function of a space or the tasks being performed within it. Lighting requirements are usually specified by value of illuminance

The National Building Code of India 2016 (NBC 2016) provides recommended values of illuminance for different types of spaces. These recommended values are based on the activities that are carried out in the space, as well as the age of the occupants.
