Figure 1 is the new office building of the Georgia Power Company in the United States. It has 24 floors and a total area of ​​approximately 73,000 square meters. The peculiar shape of the building, the south facing walls, like the inverted stairs, contracted inwards from the top to the bottom, and the highest level protruded 23 feet (about 7.01 meters) from the lowest level (Fig. 2). In the summer, the incident angle of the sun is high, and the prominent part of the upper layer acts as a sunshade so that the sun cannot enter the lower windows; in winter, the incident angle of the sun is low.
