The Industrial and Commercial Bank of China Beijing Headquarter, designed by SOM Architect, is a 13-storey building with nearly 130 thousand square meters building area. The building has two sections, and are sub-rectangular and arc shaped respectively. The sky bridge in the middle links the two sections together as one. Its steel structure as a whole is of technically demanding and complex. And because of this, the project is awarded the “Luban” national architectural award.

Lighting Design

The primary goal for lighting design in owner’s brief is high energy efficiency, followed by that is a management control system to create a good atmosphere to enhance the building’s lighting quality. In order to achieve the desired lighting effects; high quality light sources, fixtures and lighting control system were used while full use of nature sunlight and hidden fixture contribute to the overall visual effect. Light sources are LED, fluorescent, halogen and incandescent, and lighting control system was used for the main lobby area, restaurant, corridors, and executive office.

Lobby

In most cases the lobby setting gives visitors the first impression of the building, therefore it is important to create a comfortable lighting environment. To achieve this goal the average colour temperature and  luminance are set to around 4500K and 364 lux respectively. The lobby lighting is controlled by Dynalite intelligent lighting control system, which is equipped with a smart clock management device. The scenes of the lobby can be set to early morning, afternoon, evening, mid-night…etc. according to different time periods and needs of lighting. Scenes can also be created for special occasions, such as festivals, special events…etc. . The corresponding scene settings can be stored in the controller via the intelligent control panel, and through programming the lighting scenes can be changed at pre-defined time. Lighting control system DUS804C and intelligent electronic sensors are used to detect the outdoor luminance level and adjust lighting levels according to the setting. In this way, lighting achieves illumination requirements and serves the purpose of energy conservation at the same time.

Canteen

In the canteen, light is mostly concentrated on the table, enhancing food colour, aroma, taste, the contrast between bright and dark forms a sense of three-dimensional visual effects, the atmosphere is lively and energetic. Light is reflected at the exquisitely carved wall decorations, enhancing the charm of the space. Luminance level is at 350 lux on average, the average colour rendering is almost 100, color temperature is at 3500K and this gives people a sense of peace. Most light sources in the canteen are controllable and with Dynalite intelligent lighting control system, various lighting scenes can be easily created to cater for different needs, for example:

Table-setting scene, desktop lights at 50%, 30% of ambient light;

Dining scene, desktop lights at 90%, 70% of ambient light;

Cleaning scene, overall 50%.

In spaces like large private dining rooms, the special JION function of this control system makes it possible to split or merge the lighting scenes for different rooms.

Corridor

For the high-end office building like ICBC Headquarter, the corridors need to be divided into different sections to fulfill various functional requirements while creating a comfortable and casual atmosphere. Fixture-wise, Philips T5 fluorescent, halogen and 12w LED are mostly used because they can help achieve the balance in illumination requirements of the design, energy saving, low maintenance costs, thus reducing carbon emissions.
Lighting control system controls the ON/OFF of the corridor lights remotely. Major equipments used are DDRC1220FR-GL, DDRC820FR and DDRC420FR switch controllers. DLE405 dimming controller DLPE9100 control panel and intelligent detectors DUS804C were installed on both sides of the elevator hall as a movement detector. Scenes are pre-set as normal day light, mid-night…etc and energy saving as well. The controlling software DLS500 automatically switches between the scenes according to the time:

1. In everyday situations, all fixtures are on, halogen fixture 80%, LED half-on; When someone enters the corridor from the elevator hall, LED will be fully on, half on LED after 5 minutes delay;
2. Energy-saving scene, the light strips will be totally off, halogen fixture 20%, LED fully on; detector in-sleep;
3. Night scenes, the light strips and some of the halogen fixtures are totally off, the elevator halogen 5%, LED half-on, 15 minutes delay and only emergency LED on.
