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. 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.
In terms of form, in addition to the illumination inside the chamber, we used the horizontal lines between the interlayer boards to add horizontal light to the building, so a partition with rhythms was delivered visually. Apart from the light of the chamber, another visual beauty was created and a new image was born.
The linear light source was hidden inside the shadow box of the interlayer boards. For the convenience of maintenance, we made the curtain-wall glass at this position openable to ensure that the lamps can be taken out and replaced. The change of the cool light of the linear light source complements the illumination system inside the chamber.
As a city, architecture exists in society, it carries people's lives and activities, and countless human events are related to architecture. If the occurrence of architectural events can promote the changes of human society, then the correct and appropriate light of architecture is the accelerator of architectural events. As a professional lighting consultant, we hope to work with architects to create more architectural events that contribute to human happiness.
Finally, this essay ends with the words written by Le Corbusier. "Our eyes are born to see shapes in the light, and light as well as shadow show these shapes. It is the light shows the basic shapes of cubes, cones, spheres, cylinders, or pyramids. They look unique and tangible. It is the light that enables to display the beauty of them."
