ABB cuts energy costs in Singapore buildings

2008-10-08 - ABB’s intelligent building installation system, ABB i-bus, has helped several landmark buildings in Singapore cut energy consumption and win industry awards for energy efficiency and low environmental impact.

By ABB Communications

ABB i-bus is the most widely used building installation system in Singapore. It has the largest installed base across the entire range of building uses – offices, factories, hotels and resorts, universities and schools, apartments, villas and bungalows.

Several of these installations have recently won best-performance awards for energy efficiency and environmental friendliness from the Singapore government and ASEAN (Association of Southeast Asian Nations).

For occupiers they have brought massive energy savings estimated by one at 17 percent and by another at around US$370,000 a year.

Best practice energy efficiency
The award-winning buildings include the Asia Pacific headquarters of Xilinx, the world’s leading provider of digital programmable logic solutions; the Southeast Asia regional headquarters of Applied Materials Inc., the world’s largest supplier of wafer fabrication equipment to the semiconductor industry; and the Singapore National Library building.


The National Library building in Singapore consumes 17 percent less energy than it was designed for and 32 percent less than the national average.

All three have won the Singapore government’s BCA Energy Efficient Building and Green Mark Award for 2004, 2005 and 2007, with the National Library building also winning the ASEAN Energy Efficient Building Best Practices Award for 2007.

Among the ABB i-bus features singled out for their contribution to the buildings’ energy efficiency are presence-controlled lighting sensors that automatically switch off the lighting in rooms and common areas after a certain period of inactivity, and ultra light-sensitive sensors that brighten or dim the lighting according to the amount of natural light entering the building.

Save energy with ease
The ABB solutions are designed to be self-operating with minimal intervention from the user. Maintenance staff can monitor, control and troubleshoot the entire system - including each and every light fitting - from one location. Sensors and software predict when the buildings’ thousands of light bulbs need replacing.

ABB i-bus is based on the international standard for the control of smart buildings using the KNX protocol. It combines in a single system the complete scope of applications including lighting and shutter control, heating, ventilation and air conditioning, security and surveillance, and energy management.

Among the many high-profile buildings equipped with ABB i-bus are the new airport terminals in Bangkok and Beijing, the seven-star Conference Palace Hotel in Abu Dhabi, the Frankfurt Stock Exchange in Germany, and the Khalifa Stadium and Sports Hall in Qatar, venue for the 2006 Asian Games.

    The 59,000 square meter National Library building, Singapore. Figures from 2006 and 2007 show that the building consumes even less energy than it was designed for. Its current consumption is 150 kW per hour per square meter, a reduction of 17 percent on the target of 178 kW/hr/sq m and considerably less than the national average of 220 kW/hr/sq m.
