Abstract
This study was conducted with an idea that practical daylighting design and control should reduce the energy consumption without eroding residents' satisfaction with luminous environment. In this research, a dynamic daylight metrics average DA300(Daylight Autonomy) and a static metric uniformity were tested to quantify occupants' luminous comfort by using statistical analysis with the data from questionnaire survey and climate-based simulation of 108 unit cases. These two metrics were found able to be complementary to each other and the benchmarks of uniformity level and Ave. DA300are 0.112 and 29.6% respectively. Luminous comfort zone was also proposed and the units with higher value of these two metrics, in comfort zone 2, have a great potential of energy saving by compromising daylighting performance. This research makes possible to predict residents' luminous comfort without the post-occupancy evaluation and guide the facąde energy-efficient design at the early stage.
