In order to implement the national energy conservation and emission reduction requirements and the green national gate requirements, the “Capital Airport Green Airport Construction Work Plan†was further implemented. The Capital Airport started the LED energy-saving renovation project for the No. 3 parking building (GTC) light source from the end of 2013. As of April 24, Capital Airport has successfully completed the LED Phase I and Phase II renovation projects of GTC Light Source. After the completion of the transformation, the GTC is expected to achieve an annual energy saving rate of more than 30.
The scope of the renovation involves fluorescent lamps for normal lighting in the GTC basement and underground second-floor parking garages, as well as normal lighting lamps in public areas. The renovation project is divided into two phases. The first phase of the project will transform the fluorescent lamps in the second floor parking area. A total of 10,000 sets of lamps will be reconstructed. The original 36-watt T8 single-tube straight tube fluorescent lamps will be replaced with 19-watt T8 LED tube lamps to achieve luminous flux. Above 2000 lumens, the luminous efficiency is greater than 75 lm/W, and the service life is extended from 10,000 hours to over 30,000 hours. The second phase of the project is to transform the lights in other areas of the GTC. In other areas of GTC, 8983 sets of fluorescent lamps, 2120 sets of downlights and 110 sets of loop lights were replaced. The fluorescent lamp is replaced by a 36-watt fluorescent lamp into a 19-watt LED lamp, achieving a luminous flux of more than 2000 lumens, a luminous efficacy of more than 75 lm/W, and a service life of more than 30,000 hours. The downlight is replaced by a 13-watt LED lamp, achieving a luminous flux of not less than 400 lumens, a system efficiency of 75 lm/W, and a service life of more than 50,000 hours. The street lamp is replaced with an LED lamp to achieve a luminous flux of not less than 600 lumens, a system efficiency of 85 lumens per watt, and a service life of more than 50,000 hours.
It is reported that the GTC with a total construction area of ​​340,000 square meters is in accordance with the zone opening mode of 1/3 of the day and 2/3 of the night. There are millions of electricity consumption in the whole year. Through the replacement of LED lamps for GTC light sources, Capital Airport has made a major breakthrough in the field of light source replacement. It is expected that the annual energy saving rate of GTC will reach 30 or more. According to calculations, after the completion of the GTC light source conversion, according to the operation mode of the existing partition opening, at least 40 lighting power consumption and 2 million yuan of lighting consumption cost can be saved in the whole year, and the illuminance and service life of the replaced LED light source and the lamp are replaced. All indicators can meet or exceed the design requirements.
