summary 
With the rapid development of digital design methods, irregular curved shapes have been more and more widely used in buildings, which not only enriches the appearances of buildings, but also provide new possibilities of improving building performance by shape designs. However, existing researches regarding building performance and shapes mostly focus on regular shapes, while curved shapes are rarely explored. This paper aims to employ design optimization method to explore the improvement of building performance that curved shapes could contribute. Specifically, office buildings are chosen as an example and the potential of improving the daylight efficiency of them by optimized curved facades are investigated. Three major cities and two orientations are involved in the investigation. The results prove that curved facades do have significant potential to improve the daylight efficiency of office buildings, and an average improvement of 0.2032 is achieved by the optimized curved facades in the 6 cases conducted in this research in terms of the areaweighted average UDI (useful daylight illuminance) compared with the same building with plane facade.
