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 for Southeast Asian Nations).
Figures from 2006 and 2007 show that one project – the Singapore National Library building – consumes even less energy than it was originally designed for. Its current consumption is 102.59 kilowatt hours per square meter per year, a reduction of 21-percent from the design target of 124.47 kWh/sqm/pa, and less than half the national average of 220 kW/hr/sqm/pa.
ABB’s intelligent lighting and ventilation systems vastly improve energy management in buildings Minimal energy consumption.
Among the ABB i-bus features singled out for their contribution to energy efficiency in buildings 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.
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 a single location. Sensors and software predict when the buildings’ thousands of light bulbs will need replacing.
In the National Library, a sophisticated localized lighting control provides after-hours lighting only at locations where light is really required, rather than illuminating the entire office area.
Best practices in energy efficiency
The other award-winning buildings equipped with ABB technologies in Singapore include the Asia Pacific headquarters of Xilinx, the world’s leading provider of digital programmable logic solutions; and the Southeast Asia regional headquarters of Applied Materials
Southeast Asia, the world’s largest supplier of wafer fabrication equipment to the semiconductor industry.
All three have won the Singapore government’s BCA Energy Efficient Building and the 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.
ABB’s 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.
Improved energy efficiency in buildings has been identified as one of the biggest potential levers for greenhouse gas reduction. In the European Union, for example, cutting energy use in buildings by about 30 percent would reduce Europe’s total energy consumption by about 11 percent according to the World Business Council for Sustainable Development.
