"A pearl river reflects the picture, and the view of the Yangcheng City is full of windows". On the evening of April 2, the Window of Guangzhou Business Port, located at the south end of the central axis of the new city of Guangzhou and the intersection of the the Pearl River Rear Channel, lit up the new landmark of the Guangdong Hong Kong Macao Bay Area, adding a prosperous scenery and a modern urban business circle to Guangzhou. Under the light, the "100" (looking from north to south) and "001" (looking from south to north) windows of Guangzhou, standing on the Pearl River, are clear and bright in shape. The facade of the curtain wall is crisscrossed with light and shadow. The windows can be framed into the central beauty of the city, such as the small man waist, the east tower, and the west tower on the central axis of Guangzhou. The windows of Guangzhou and the the Pearl River are painted against each other, and are lit up into a gorgeous ocean, as if a shining art treasure shines brightly in the city, showing the world the modern style of Guangzhou's millennium commercial capital. It is understood that the total construction area of the Guangzhou Window Business Port project is about 560000 square meters, with a planned total land area of 167000 square meters. It is invested and developed by the main subsidiary of China Communications Group in Guangdong, China Communications Fourth Navigation Bureau, and is constructed in three zones: ABC. It is a key construction project in Guangzhou and one of the top 500 modern industries in Guangdong Province. The project is located in the core area of Guangzhou City, adjacent to famous landmarks such as the Pearl River New Town and Guangzhou Tower, and is an urban complex integrating multiple functions such as headquarters office, business hall, business travel exhibition, art exhibition center, product exhibition and release center, and river view theme park. A district was completed and put into operation in 2015, attracting hundreds of enterprises to settle in and has become an important gathering area for the headquarters economy of Guangzhou's central axis. Zone B will be put into use by the end of 2021, and various operational work is steadily progressing. After the comprehensive lighting of Zone C, the project construction will be carried out in an orderly manner according to the plan, and it is planned to be put into use in 2025. Liang Houzun, the project leader of Guangzhou Window C area of China Communications Fourth Navigation Bureau, introduced that during the construction process, the project team adopted various energy-saving and environmentally friendly new building materials, and applied multiple energy-saving and emission reduction technologies and measures. To ensure that the window lighting in Guangzhou is both beautiful and environmentally friendly, the project team has adopted many energy-saving and consumption reducing materials with high technological content. For example, LED linear wall washing lamps have high technological content in light source selection, energy saving and consumption reduction, and lighting quality. Compared with traditional lamps, they have the characteristics of fast lighting response, high brightness, good heat dissipation effect, no heavy metal pollution, and long service life; Adopting intelligent modules and 512 control, the brightness can be adjusted to achieve on-demand lighting and reduce energy waste, with electricity consumption lower than a quarter of traditional energy-saving lamps; The concealed installation form of the sunshade light groove is used, and the size and angle of the light fixture selection are perfectly matched with the light groove. The luminous surface is made of frosted glass material to reduce the optical rotation and achieve the effect of seeing light but not the light. It is reported that the overall lights of Guangzhou Window Business Port are on, marking the flowering of the urban complex promoted by the strategic cooperation between China Communications Group and the Guangzhou Municipal Government, and providing a new window for the business development of the Greater Bay Area.
