Daylight and energy performance are essential for sustainable building design. Skylights and clerestories are effective strategies for providing sufficient daylight while reducing building energy requirement. To identify the most influential variables of the skylight and clerestory design, a parametric design model of a retail building is developed and 1000 design options are randomly selected. Integrated daylight and energy simulations are performed for each option to evaluate the lighting and thermal loads simultaneously. The performance indices for daylighting and energy performance evaluation are Useful Daylight Illuminance (UDI) and Energy Use Intensity (EUI). Then, a sensitivity analysis is used to rank building design variables according to their contribution to the variance of UDI and EUI. The design features of the optimal and worst design options are also discussed.
