Zhong Zhao Award Third Prize: Beijing Microsoft China R & D Group Headquarters Indoor Lighting Project

The headquarters of Microsoft China R&D Group is located in Zhongguancun Square, the core business district of Zhongguancun, covering an area of ​​11,600 square meters. Two buildings are built in the headquarters campus. The south building is 80 meters high, the ground floor is 18 floors, and the underground is 4 floors. The north building is 65 meters high, the ground building is 15 floors, and the underground is 4 floors. The 3 floors of the two buildings are connected by an air corridor. The two buildings have a total gross floor area of ​​approximately 150,000 square meters.

The construction of the headquarters building exceeded US$280 million and was completed in 2011, becoming Microsoft's largest R&D park overseas. After the new park is completed, it can accommodate 8,000 people to work together.

Microsoft's China R&D Group headquarters project uses a large number of PHILIPS series lighting products, including open office dimmable hoisting grille lights, competent office dimmable hoisting grille lights, computer room embedded grille lights, staff restaurant adjustable Color LED wall washers, halogen spotlights in the reception area, compact energy-saving fluorescent lamps in the corridor area, etc.

Minimizing energy consumption is the highlight of the lighting design of this project. In the selection of lighting products, PHILIPS's energy-efficient lamps, light sources and electrical accessories were selected to ensure that the functional lighting requirements were met while minimizing energy consumption. The use of dimmable products in key areas such as open offices and executive offices, using a combination of luminaires and control systems to provide the required light to the office space when needed. Lighting products use human motion detectors and dimming control knobs. When the people in the room or area are all gone, the mobile controller will automatically turn off the lighting in the room or area, and the lighting can save up to 30%. Using the dimming control knob combined with the dimmable ballast built into the luminaire, you can adjust the proportion of the illuminator up and down, and set the appropriate illuminance according to the different needs of the room. The mobile controller combined with the dimming control knob can save up to 70% of the maximum lighting energy, reduce operating costs, and greatly improve the return on investment of customers.

In addition, the lighting scheme fully takes into account the psychological changes of employees at different times of the day and different seasons, and uses the changes in color and color temperature to create a humanized lighting scheme. In order to meet the simple and bright interior decoration style, the lighting products adopt special customized hanging grille light strips, and different lengths can be customized according to different office spaces. The luminaire uses a combination of direct illumination and indirect illumination, and the light distribution of the upward and downward illumination is in two distinct ways. The light distribution on the upper light is narrower, and a light strip is formed on the ceiling, which can illuminate the ceiling and make the office space appear wide. The light distribution of the light for the batwing light distribution can improve the uniformity of the office space. It is also possible to adjust the proportion of the illuminator up and down, and set the appropriate illuminance value according to the different needs of the room.

At the beginning of the lighting design, it was considered to make full use of natural light. The curtain wall of this project is a large-area glass combined with aluminum alloy frame, which can collect natural light very well, so the power density of the lamps near the window is slightly lower and the dimming control knob can be used to adjust the indoor illumination level according to the natural light condition.

This project won the third prize of Zhongzhao Lighting Award.
