We show the effect of daylighting system and the change in required illuminance on the energy efficiency and quality of indoor lighting environment. Not only the quantity of a daylight illuminant but also the quality should be evaluated to improve daylighting and blind control. The results of experiments show that the further reduction of lighting energy consumption and the reflection of color temperature to the interior light environment can be obtained by lowering the lower limit of modulated light and the required illuminance.
