EGAT launched the Label No.5 Air Conditioner programme, following the success of Label No.5 Regrierator programme. Air conditioning is a high-growth and the highest energy consuming appliance, especially during summer period in Thailand. The opening ceremony for the project was held on the 20th September 1994 by the cooperation of air conditioner manufacturing companies to decide the criteria for energy efficiency and develop air conditioner in order to acquire Label No.5 which Electrical and Electronics Institute (EEI) is the third party who perform energy efficiency test.  
In 2004, the Thai Industrial Standard Institute (TISI), declared the Minimum Energy Performance Standard (MEPS) for the air conditioner per chamber size 8,000 and 12,000 watt perform energy efficiency rate above 2.82 and 2.53 (9.6 and8.6 BTU/hr/W) respectively. The law becaome effective in March 2004. Hence, air conditioners in the same spec must qualify by TISI2134-2545 to be legally manufactured and distributed in the country. Enhancing in energy saving, label no.5 criteria for air conditioner increased from EER 10.6 to EER 11 which reduce the electricity consumption up to 5 percent since the beginning of the project in January 2005 until present. 
According to lael no. 5, the Energy efficiency ratio (EER) is the following: 

Energy Efficiency Ratio(EER)
Label no.5 Air conditioner

(Air conditioner Size < 8000 Watt, 27296 BTU/Hr.)

Efficiency Energy Efficiency Ratio (EER)
No.5 above or 11.60
No.4 above or 11.00 – less than 11.59
No.3 above or 10.60 – less than 11.00

Energy Efficiency Ratio(EER)
Label no.5 Air conditioner

(Air Conditioner Size> 8000 Watt, 27296 BTU/Hr.)

Efficiency Energy Efficiency Ratio (EER)
No.5 above or 11.00
No.4 above or 10.60 – less than 10.99
No.3 above or  9.60  – less than 10.59


Standard air conditioner is worth replacing with Label no.5 one
