NEW DELHI: Power minister RK Singh said on Friday that the government will consider making 24 degrees celsius as mandatory default setting for air conditioners within a few months.
At a meeting with the minister, AC makers were also advised to have labelling indicating the optimum temperature setting for the benefits of consumers both from financial and their health points of view, the power ministry said in a statement.
The temperatures settings in ACs will be in the range of 24 to 26 degrees celsius, it said.
Singh launched a campaign to promote energy efficiency in the area of air-conditioning.
"Every one degree increase in the air-conditioner temperature setting results in saving of 6 per cent of electricity consumed," the statement quoted him as saying.
He added: "Normal human body temperature is approximately 36-37 degrees celsius, but large number of commercial establishments, hotels and offices maintain temperature around 18-21 degrees celsius. This is not only uncomfortable but is actually unhealthy."
He was of the view that setting the temperature in the range of 18 to 21 degrees celsius compels people to wear warm clothing or use blankets; therefore, this is actually wastage of energy.
Some countries like Japan have put in place regulation to keep the temperature at 28 degrees celsius.
Therefore, he said that under the guidance of ministry of power, the Bureau of Energy Efficiency (BEE) has carried out a study and has recommended that the default setting in the air-conditioning should be at 24 degrees celsius.
The new campaign will result in substantial energy savings and also reduce greenhouse gas emission, he added.
The minister further said that to begin with this will be an advisory to be issued to all establishments and manufacturers.
After an awareness campaign of 4 to 6 months, followed by a survey to gather public feedback, the ministry of power would consider making this mandatory, the minister added.
The power ministry estimates indicate that if all the consumers adopt, this will result in savings of 20 billion units of electricity in one year alone.
According to the statement, AC makers at the meeting have agreed on this and appreciated it as a step in the right direction.
