R K Singh, Minister of State (IC) for Power and New & Renewable launched a campaign to promote energy efficiency in the area of air-conditioning. Speaking on the occasion, he said, “Every one degree increase in the air-conditioner temperature setting results in saving of 6 per cent of electricity consumed. Normal human body temperature is approximately 36-37 degree Celsius, but large number of commercial establishments, hotels and offices maintain temperature around 18-21 degree Celsius.
This is not only uncomfortable but is actually unhealthy. Setting the temperature in the range of 18-21 degree 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 degree Celsius”. Therefore, 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 degree Celsius. The new campaign will result in substantial energy savings and also reduce greenhouse gas emission. To begin with this will be an advisory to be issued to all establishments and manufacturers. Manufacturers are advised to keep the default setting of air conditioners at 24 degrees Celsius and also to carry out labelling indicating the optimum temperature setting for the benefits of consumers both from financial and their health points of view.
