建筑由日本知名设计所sako设计，位于济南的城市主干道经十路上。办公楼的功能定位使他在大的形体上较为工整。建筑的最大魅力是在晶莹剔透的长方形体上掏了一些不规则的洞，在功能上达到引入光线和通风的目的，在视觉效果上打破人们对传统建筑平铺直叙的想象，创造一个熠熠生辉，曙光女神水晶般的新兴城市建筑。照明设计沿着这一理念，运用冷色光的变幻，将光线与玻璃结合，营造晶莹剔透的水晶感。

The building is designed by the famous Japanese design institute sako which is located on the main road of Jinan—Jingshi Road. Its big body is orderly for the functional positioning of the office building. The greatest attraction of the building is that it has some irregular geometric holes on the crystal-like rectangular body. It could achieve the purpose of introducing lights and ventilation. It creates a sparkling, crystal-like, new urban architecture of the twilight goddess rather than leave a traditional image to people. The lighting design follows this concept, the transformation of cool light is applied then light was combined with glass to create a crystal clear look.

在本项目中，玻璃的反光率是我们要面对的最大挑战。如何使光线恰到好处地落在玻璃上进行反射，同时，可以反射光线的玻璃又可以满足一定的透光率，从而不影响建筑室内白天的采光。在我们与建筑师和幕墙工程师共同探讨了玻璃的具体参数后，为腔体的照明选择了三种组合光去实现。第一种为大功率上照灯。将足够的光线洒入腔体中，给腔体内部打上一层底色。由于腔体内部为可上人平台，我们将大功率投光灯进行了隐藏，以避免对人们的视觉进行干扰。第二种，为位于室内的线性洗墙灯。由于玻璃为半透光，其对于腔体的光环境有较为重要的影响，我们又将它进行了重点渲染，使腔体的内部立面突出。第三种为重点照明的小型投光灯，它们的作用是将腔体中的细节进行第三度的重点刻画。墙体内部的照明系统概括为以上三种，因为我们深深地知道，优秀的照明设计是有深度和空间感的，是多元的组合，而不是粗浅单一的。

In this project, the reflective rate of glass is the toughest challenge we have to face. The problem lies in how to make the light fall on the glass in a right way. At the same time, the glass that can reflect the light can satisfy a certain light transmittance without affecting the indoor daytime lighting in the building. After discussing the specific parameters of the glass with the architects and the curtain wall engineers, we chose three combinations of light for the illumination of the building-chamber. The first type is high-power up light. Sufficient light was cast into the chamber to give the interior space a ground color. Since the interior space is a human-accessible platform, we chose to hide the high-powered floodlights to avoid interfering the vision of people. The second type is indoor linear wall washer. Since the glass is semi-transparent, it has an important influence on the light environment of the chamber. We have also focused on highlighting the internal elevation of the chamber. The third type is small-sized spotlight which plays the role of accent lighting. Their role is to focus on the details of the chamber for a third time. The lighting system inside the wall can be summarized as the above three. For we all deeply know that excellent lighting design is connotative and it has a sense of space. It is a combination of diversities rather than a single one.
