Light in action The new PetroChina HQ in Beijing incorporates energy-saving systems and advanced building management technologies, founded on a lighting control system from Philips Dynalite. 8 | Lightnews Vol 10 PetroChina HQ sets the standard Incorporating China’s largest DALI lighting installation, PetroChina HQ’s lighting control system is setting the standard for flexible controllability and ‘green’ building performance, further enabled through Philips luminaire technologies. Equipped with a range of energy-saving systems and advanced green building management technologies, the new headquarters of China’s largest oil and gas producer/distributor, PetroChina, has redefined office building performance— operationally and environmentally. In fact, PetroChina HQ has set a new benchmark for efficiency, and has emerged as a potential reference case for the development of a China-specific ‘environmental performance’ building standard. One of the key sustainability initiatives used in PetroChina’s new state-of-the-art headquarters is a sophisticated, intelligent lighting control system from Philips Dynalite. This, along with the latest energy-efficient luminaire technology from Philips, provides PetroChina with a powerful combination of lighting control flexibility and functionality. PetroChina HQ’s lighting control system permits lighting levels to be tailored to the use of space, allowing total flexibility for zone switching and dimming. This, coupled with presence sensing functionality, ensures no areas are overlit or illuminated when not in use, resulting in energy savings. Importantly, the lighting control system supports China’s largest DALI lighting application—it incorporates over 8000 individually addressable fluorescent HF DALI ballasts, in addition to the system’s 2500 switched circuits. This facilitates a high degree of ‘granular’ control, allowing operators to easily customise lighting schemes to specific areas, office configurations and events. Control groups/zones can be configured without reconfiguring the fittings themselves.
Lights off after hours The lighting control system is programmed to operate in three distinct automated modes—‘working’, ‘lunch’ and ‘after hours’ (security and cleaning)—which are timer-based. Although the precise timing and functionality is individually configurable for each floor and/or zone, it essentially corresponds to ‘lights on’ at the commencement of working mode, followed by a timed sequence of dimming to lunch mode, ending in ‘lights off’ when the system goes into after hours mode. At this time, motion sensors are activated in amenities areas and lift lobbies to initiate lighting if motion is detected. Intermittent-use areas, such as meeting rooms and function areas, utilise motion detection at all times. “This level of operational flexibility simplifies the management of lighting energy consumption for the entire building. By simply ensuring that lighting is only activated when and where it is required, energy savings can be realised and money saved.” says Jimmy Du, Managing Director of Bridges Electronics, the Philips Dynalite distributor for China. From a luminaire perspective, a distributed solution was selected for PetroChina HQ’s office areas. Highly energy-efficient Philips luminaires were utilised to achieve the required lux levels. When paired with the lighting control system, the luminaires provide enormous potential for energy savings. “ Operational flexibility simplifies the management of lighting energy consumption for the entire building. ” Automated mirror blinds PetroChina HQ is equipped with a number of additional innovative design features aimed at optimising environmental performance. Automated mirror-coated blinds mounted on the exterior of the building windows track the sun during the day and reflect light into the building’s interior. Here, natural light levels are enhanced with the required amount of artificial light, allowing PetroChina to save energy while keeping lux levels within a predetermined range—no matter what time of day or year. This optimisation of natural light levels is achieved by the daylight harvesting functionality of PetroChina HQ’s lighting control system. With the aid of sensors, light levels can be modulated automatically according to the level of natural light available. Comprising four adjoining multi-storey buildings, PetroChina HQ has set a new benchmark for building performance and efficiency in China. With the automated lighting control system online building-wide, PetroChina HQ is reaping the energy saving rewards. Thanks to the building’s scalable control architecture, future expansion promises to be straightforward with additional thirdparty controllers for other applications easily integrated. This scalability is also reflected by the lighting control system. Here, all of the DALI universes are below capacity and the existing lighting control system network is as scalable as it is robust—additional lighting applications are easily incorporated into the existing architecture. With the support of innovative solution providers, PetroChina will continue to set the benchmark for ‘green’ building performance in China. Lightnews Vol 10 | 9
