Just what we need ... an Air Conditioner Index

THE Shanghai Meteorological Bureau thinks the city's residents don't know when it's too hot outside and plans to launch an "Air Conditioner Index" by the end of June.

Bureau officials said yesterday the index was necessary for residents, who use their air conditioners anywhere from 111 to 154 days per year.

Amazingly, they considered the index so crucial to daily life that they gathered information for the idea during a five-year study.

With the Air Conditioner Index, residents will have a better idea when to use their air conditioners and thus "live a healthier life and save energy," said Feng Lei, deputy director of the bureau.

The index will have four levels including "unnecessary to use air conditioner" to "turn on the air conditioner for a long time," said Dr Tian Zhan, a meteorological expert with the bureau.

Residents will save 330 kilowatt-hours of electricity on average each year if they follow the bureau's index. This should equate to about 200 yuan (US$30.50) in annual savings, officials said.
