Cooling Temperature Settings for AC
In view of reducing energy demand Bureau of Energy Efficiency has announced energy saving measures. Main content is quoted below
With the objective to reduce energy intensity, in the area of space cooling, BEE initiated
Star Labeling of Air Conditioners to improve efficiency in commercial and residential buildings. Thereafter, the Energy Conservation Building Code (ECBC) was published to reduce demand for space cooling. It is estimated that by increase in temperature of room by 1 degree Celsius (0C), we can save about 6% of electricity. Typically, room temperature is set between 20-21 0C whereas, as per the comfort chart, it is suggested that ideal temperature could be maintained around 24-25 0C. Considering change from 20 0C to 24 0C, there exists potential to increase at least 4 degree Celsius, which may lead to savings of about 24% of electricity consumption. Annually, this may translate to saving potential of about 20 billion units of electricity, by taking simple measures like adjusting the temperature setting of AC system to 240C.
