Case Study : Environment Conservation
-
The Union Ministry of Power is considering making 24 degrees celsius as mandatory default setting and labelling of air conditioners.
-
It will result in substantial energy savings and also reduce greenhouse gas emission.
-
Every one degree increase in temperature of air-conditioner results in saving of 6% of electricity consumed.
-
It will result in savings of 20 billion units of electricity per year.
Scientific reasons
-
The normal human body temperature is approximately 36-37 degree Celsius.
-
Lower temperature around 18-21 degree Celsius controlled by air conditioners especially in large number of commercial establishments such hotels and offices is not only uncomfortable but is also unhealthy.
-
Setting lower temperature in the range of 18-21 degree Celsius compels people to wear warm clothing resulting in wastage of energy.
