In my opinion, Yes, because:

1. Each room, where people long time reside, should have also a lighting of people for a long time feel.

2. The same high, such as for DSE workstations, what's the amount of light, lighting quality and glare requirements for libraries.

3. The opening hours of most libraries spanning throughout the day into the night. The lighting of the building should behave appropriately the.

4. Areas with plenty of natural light need artificial light in daylight quality, avoiding twilight situations.

The library is also only an Office

For optimum illumination, plan how you would plan the optimal Office.

Pay attention to wall or shelf illumination. About two-thirds vertical illuminance on the wall in relation to the Visual task or to the Clipboard.
 
(Note: the coefficient of reflection of the books of ρ ~ 30%, the desired luminance ratio of storage wall is between 1:2 and 1:5)

Note the usage times, including special uses and provide the appropriate light colours. Note: offer always the light that would be available in the nature at the same time: during daylight, night fire range.

With a superior automatic control system that is regulated.

Provide temporally and spatially limited interventions in the light situation.
