(China Glass Network) Skyscrapers also use glass curtain wall. But it would cause light pollution because of large scope of reflection of building’s mirror. It is noted by environmental evaluation report, flute Lane building is 248.8 meters high. Glass reflection focus on the time period after sunrise and one to two hours before sunset-the impact of this time period is large and long. With the rising of solar altitude, the influential size of reflection light would be less. Its affective target of this project area is followed: residential area, Vehicles and pedestrians on roads, hotels, and enterprises and public institution nearby.
Design units had solutions for this trouble. We should adjust underlying materials of glass façade and not change the overall layout. The color that we choose must be not light. People should choose that kind of glass whose reflection rate is less than 0.16 according to requirements. Whereas, people should choose that kind of glass whose reflection rate is less than 0.3 in middle and high glass curtain materials. Besides, people should choose the material with small lustrousness of mirror as possible as you can. Meanwhile, we should not use glass with arc concave or convexity in order to avoid spreading and gathering light; that is not good for light pollution reducing.
