Straits Times 22 Apr 08;This back lane in Boat Quay gives an idea of Singaporeans' penchant for air-conditioning. Air-cons account for the lion's share of electricity consumed in buildings - up to 55 per cent of a building's energy usage. Although air-conditioners are the biggest energy wasters, they also have the largest potential for savings. By makingadjustments, somebuildings can even halve their energy bills.
To do your part on Earth Day today, here are some energy-saving tips from the National Climate Change Committee.
# Avoid placing heat-generating appliances near the thermostat, which may cause the air-conditioning unit to operate longer than necessary.
# The ideal indoor thermostat setting is 25 deg C.
# Dirty air filters impede airflow, leading to increased energy consumption. Clean air filters once a month or replace them when necessary.
# Regularly service your air-conditioning units.
# Direct sunlight on the air-conditioning unit's outdoor heat exchanger decreases its efficiency. Consider shading the air-conditioner where necessary, but do not block the airflow.
