Hong Kong slashes energy costs by cutting air conditioning

Hong Kong has saved the equivalent of 70 million kilowatt hours a year by turning down the air conditioning in government buildings, according to city officials.

In 2004 all Government departments were ordered to turn down indoor air conditioning to 25.5 degrees Celsius to save energy.

According to the latest figures power usage in buildings fell from 2,190 million kilowatt hours in 2004/2005 to 2,120 million kilowatt hours in 2006/2007.

However, overall energy consumption and electricity spending by the Government has risen over the same period due to new buildings and facilities being opened.

The Government is now considering further action. In some shopping centres and offices within Hong Kong it is normal practice to have air conditioning turned down to below 20 degrees Celsius during the summer months.
