Tips: Please always refer to the EER value when you want to purchase an air conditioner. EER is called the Energy Efficiency Ratio, it is the cooling capacity provided by the air conditioner per hour in every kilowatt. Higher level of EER indicates more energy saving and higher cooling capacity. EER = (cooling capacity Kcal (BTU)/h) / power input (W).         Do not wear tie, reduce dependency on air-cond This is recommended by American magazines that it can be applied to the office setting of US. By doing this, it can help the guys to work at a room temperature of 28 degree celsius, in which it is estimated to reduce 7 millions of carbon dioxide emission into the surrounding.

Note that with every drop of 1 degree celsius, it will increase 6% of energy consumption.
