Green Conversion Accelerates Innovation - Transformation of Lighting System in the Tunnel Tunnel Building

Office lighting is a big energy consumer in the city. Due to the high energy consumption of the lighting system, a large number of existing office buildings consume a large amount of energy in the city and emit a large amount of carbon dioxide, which places a great burden on the city's environment. As a leader in the lighting industry, Philips Lighting has been committed to promoting green office building lighting, proposed a green transformation, accelerated the concept of innovative green office lighting, and developed energy-efficient office lighting sources, appliances, lamps and control systems for the green office. The building offers a complete green lighting solution. Shanghai’s Shen Tunnel Building has been transformed by Philips Lighting’s lighting system to achieve significant energy savings, with energy savings of up to 75% in some regions, making it a classic example of the transformation of office lighting systems.

Shen Tunnel Building is a new office building of the Shanghai Tunnel Design Institute. The building is a retrofit of the old building. The entire building has a total of 15 floors. The overall structure is open-plan office space with no ceilings and three-window windows. Upon entering the Shen Tunnel Building, it was felt that Philips' converted building was soft and plentiful in lighting, visually comfortable, and creating a high-end office atmosphere. The lighting system designed by Philips was very simple. We only saw the downlights installed in the hallways. We saw rows of neat rows of hanging luminaires in the office at Nuoda, and we did not even see the light switches on the walls. Why is a lighting system that is so simple, which can save energy up to 75%?

"The lighting system of the tunnel building is very simple, but it is smart!" Philips lighting engineers told us. The entire tunnel lighting system uses only Philips FBH125/FBH135 high-performance downlights and TPS498 suspended luminaires, but due to the adoption of Occuswitch motion detection system and Luxsense daylight sensing system, the lighting of the tunnel building is "intelligent" and thus easy to use. Achieve energy saving goals.

"The Philips Philips TPS498 Suspension Fixtures are the first to be highly efficient and can reduce energy consumption," said Philips Lighting Engineer. The Philips TPS498 suspension luminaire uses Philips' new OLC full-brightness control optical system. The three-dimensional full-surface luminaire grid design maximizes the efficient use of light, using high-grade reflective aluminum and overhead reflectors for maximum efficiency Up to 80%, with Philips T5 fluorescent tubes and electronic rectifiers can greatly reduce energy consumption. The TPS498 lamps provide a wide and uniform light distribution, making the entire office area soft and soft, without reflecting glare on the computer screen, and truly achieving a comfortable and efficient unity.

In addition to the high efficiency of lamps and light appliances, energy saving is another important reason for the installation of the Occuswitch motion detection system and the Luxsensen daylight sensing system. The Occuswitch is a Philips control sensor that is widely used in office lighting. The Occuswitch's independent motion detector has a human movement detection function that detects human activities in the environment. When the detector detects that the environment is empty, it automatically turns off the lighting. System, so as to achieve the purpose of energy saving. We have seen the installation of many beautiful, sophisticated circular occuswitch sensors in the open office area, like an electronic eye, with due diligence in controlling the opening and closing of the lighting system. Occuswitch realizes intelligent switching of lighting through motion detection, effectively reducing energy consumption. The Occuswitch can also provide a forced solar shutdown system. The Occuswitch will turn off the lighting system when there is sufficient sunlight in the room. In addition, since the open office area of ​​the tunnel building is fully exposed to light, the Philips Luxsense daylight sensor system is also installed in the area near the window when designing office lighting to detect the intensity of natural light. Luxsense daylight sensing system will reduce the illumination of the artificial light source properly and even turn off the lighting system when the daylight is sufficient and the working illumination is satisfied. This brings additional energy savings.

The combination of the Occuswitch motion detection system and the Luxsensen daylight sensing system enables the simplest intelligent lighting system, eliminating the dependence of office personnel on manual switching. There is no lighting switch installed in the office area of ​​the tunnel building. The Philips Occuswitch motion detection system, Luxsense daylight sensing system, and highly efficient suspension fixtures TPS498 and T5 light source and electronic rectifier form the “smart” green lighting system of the Shen Tunnel Building. It is such a Philips "smart" green office lighting system that makes the office lighting of the Shenhu tunnel building save energy consumption greatly before the transformation, and the energy saving in some areas can reach up to 75%, becoming a successful example of the renovation of old office buildings. . According to industry experts, China currently has a large number of office buildings with poor lighting systems, which has become a huge burden on urban energy consumption. Only by upgrading existing office buildings to green ones and achieving green transformation, can our city achieve sustainable development. .
