Olympic lighting system under control

Electrical Review Logo

Echelon Corporation has announced the Olympic Village in Beijing is using its LonWorks technology to create an energy efficient lighting control system.

Lighting typically consumes as much as a third of the electricity used in a building, making it a prime target for energy efficiency for the Olympic village during the games. The smart control system integrates all lighting subsystems to optimise energy usage while maintaining a safe and aesthetically pleasing environment for the athletes – contributing to the government's pledge to stage a ‘green Olympics'. Beijing is committed to reducing energy and water consumption per unit of GDP by 5% this year as part of a push for a ‘recycling economy' in time for the Olympics.

Vincent Wang, general manager of Lang Meng Technology, said: "There are a vast numbers of devices scattered across a large area, serving the many needs of the village from beautification, to safety, to energy efficiency. It is extremely important to China the village be seen positively by the tens of millions of viewers that will be watching the Olympics on television. Because the LonWorks products from our various suppliers integrate easily, we were able to install and configure the project in less than two months, helping to ensure the Olympic village will open on schedule."

The lighting control solution uses LonWorks enabled power controllers and analog input modules from Nico Technology to control the lighting system, and to monitor output status. Echelon's LNS network management software was used to design and install the network, and Echelon's i.LON internet servers automatically turn on or off lights based on pre-programmed scheduling functions. The i.LON servers interface with Advantech Industrial Automation Group's WebAccess HMI, which can be used to monitor and control the system from the property management centre.

The LonWorks control technology is incorporated in the Chinese national standard for building automation, intelligent residential community construction, and is the national standard for control applications.
