Daylight using in office space not only has the energy-saving potential, but also achieve visual requirements and improve work efficiency. In the past, "Daylight factor (DF)" has always been the mainstream of building daylight specifications. However, "static" Daylight factor cannot fully reflect the change of time, nor the relationship between building orientation and external shading. In recent years, "Dynamic Daylight Metrics" based on meteorological data has become a new evaluation trend, which can accurately evaluate the daylight quality in the annual working hours of the building. To evaluate the daylight condition of Taiwan’s office space, this study used the "standard Meteorological Year (TMY3)" as the database of climate, and applied the dynamic lighting index "Spatial Daylight Autonomy (SDA)" and "Annual solar Exposure value (ASE)" as the dynamic daylight evaluation index, which are commonly used internationally. Through simulation with DIVA for Rhino software, daylight design strategies such as window-to-wall ratio, window types, shading for office space were discussed to achieve the purpose of sustainable building design and high-quality daylight environment.
