Provide individuals with access to lighting environments that can be customized to their requirements.
Humans spend about 90% of their time indoors and the ambience of the indoor environments has an impact on the well-being and productivity of occupants. Lighting in a space has been shown to have a positive impact on mood and cognitive performance. Lighting environments that are customizable by individuals have been shown to improve satisfaction levels.
The ages of occupants have an impact on the light levels required for visual acuity. Lighting guidelines recommend twice the light levels for individuals over the age of 65 years compared to individuals between the ages of 25 years and 65 years. As humans age, the transmission of light through their lens is reduced. This is due to age related changes including increased light absorption by the lenses , smaller pupil size, increased scattering of light due to thicker lenses and yellowing of the lenses .
