ABSTRACT

As daylight varies throughout the day, it cannot provide targeted illuminance levels the whole day. Sensors can be used to measure the deficit in the illuminance levels and can control the artificial lighting to provide the balance lumens. The operating level of artificial lights in daylit areas can be varied to achieve energy savings. Energy simulation tools are capable of handling this phenomenon. This chapter explains this through following two tutorials: evaluating the effect of daylighting-based controls on the energy consumption and evaluating the impact of daylight sensor positioning on the energy consumption. No lighting control and linear/off lighting controls are needed to evaluate for evaluating the impact of daylighting-based controls. A 10 m * 10 m single-zone model with one window only on the south facade is used to evaluate the impact of daylight sensor placement.
