Energy-saving efforts in offices across Hong Kong has saved the government HK$3 million a year on its electricity bill. The Government Property Agency yesterday said buildings jointly used by government departments showed a general reduction in power consumption over the past two years. The agency is responsible for managing 50 buildings jointly used by various departments, amounting to a total floor area of 918,879 square metres. Since 2003/04, the total power consumption of these buildings has fallen by 1.6 per cent to 257,542,949kWh in 2004/05 and 2.9 per cent to 254,276,124kWh in 2005/06, a spokesman for the agency said. 'In 2005/06 alone, the saving in the power consumption was 3,266,825kWh, which is equivalent to about HK$3 million,' he said. The agency said that with increasing computerisation, more office automation and growing demand for government services in recent years, there had been growing pressure on energy consumption. However, with a number of effective measures and the co-operation of all departments, power consumption had fallen over the past two years. The measures included carrying out energy audits on buildings, the installing of energy-saving lighting and modifying air-conditioning use. Setting the air-conditioning temperature at 25.5 degrees Celsius and switching off equipment that was not being used also formed part of the energy-saving measures. 'Despite the success in reversing the growing power consumption in government office buildings, there is no room for complacency,' the spokesman said. 'We will continue to work with our property management agents and departments to identify new opportunities and achieve further savings in power consumption.'
