Energy Efficiency Criteria for Material and Electrical Equipment to Qualify for the Minimum Energy Performance Standards Star Rating

To further promote the efficient use of energy in the country, the Minimum Energy Performance Standard (MEPS) has been introduced by the government for efficient electrical equipment and material. To meet the requirements of the MEPS, the performance criteria when tested using the relevant testing standards has to be met. The testing standards and performance criteria have been set for the following equipment.

Performance Indicator and Testing Standards

  • Energy Efficiency Ratio (EER) based on tests done in accordance to MS ISO 5151:2004 (Non-ducted air conditioners and heat pump: performance indicator and testing standard).
  • The tests can be either the Balanced Type Calorimeter or Psychometric type.
  • The tested capacity value must be at least 90% of that declared by the manufacturer.
  • The EER is calculated as shown below:

  • The Star ratings based on the EER values are as shown below.

a) Cooling capacity < 4.5kW.

Star Rating
EER Value (Btu/h/w)
5
≥11.94
4
11.16-11.93
3
10.37-11.15
2
9.56-10.3
1
9.00-9.55


b) 4.5kW  ≤  Cooling capacity  ≤  7.1kW

Star Rating
EER Value (Btu/h/w)
5
≥10.71
4
9.83-10.70
3
8.94-9.82
2
8.03-8.93
1
7.50-8.02

 

Criteria for MEPS

Appliances should have at least a 2 STAR rating.
Performance testing is to be done by SIRIM or any laboratory recognised by Standard Malaysia.
