The daylighting in office can not only save the energy, but also meet the physical and psychological needs for eyes, and finally lead to higher work efficiency. Solving the daylighting problems in the high-rise office buildings is urgent. The core position in the high-rise building is an important factor to affect the light in office. In this paper, the author analyses the lighting characteristics of three types of the core position, which is core in the center of the building, core at the peripheral of the building and the core separated from the building. Combined with the natural lighting assistance measures, some design essentials were raised in this paper.
