  NOTIFICATION  
The following notification is being circulated in accordance with Article 10.6  
 
1. Notifying Member:  SINGAPORE   
If applicable, name of local government involved (Article 3.2 and 7.2):   
2. Agency responsible:  National Environment Agency (NEA)  
Name and address (including telephone and fax numbers , email and website 
addresses, if available) of agency or authority designated to handle comments 
regarding the notification shall be indicated if different from above:   
3. Notified under Article 2.9.2 [X], 2.10.1 [   ], 5.6.2 [   ], 5.7.1 [   ], other :  
4. Products covered (HS or CCCN where applicable, otherwise national tariff 
heading. ICS numbers may be provided in addition, where applicable):  
HS: 8415:10XX ; Variable refrige rant flow (VRF) air -conditioner: a multi -split system is of 
variable refrigerant flow or VRF type if it has one or more outdoor units comprising a single 
refrigerant circuit, each of which has a set of refrigeration ports that services the network 
of indoo r units through branch piping or distribution devices or both . 
5. Title, number of pages and language(s) of the notified document:  Energy 
Conservation (Prescribed Regulated Goods) Order 2021 and Energy Conservation 
(Regulated Goods and Registered Suppliers) Regulations 2021 - notice will be published in 
the Republic of Singapore's Government Gazette when adopted.  
6. Description of c ontent:   
NEA introduced the Mandatory Energy Labelling Scheme (MELS) and Minimum Energy 
Performance Standards (MEPS) in 2008 and 2011 respectively.  
The existing Energy Conservation (Prescribed Regulated Goods) Order 2017 and the 
Energy Conservation (Regulated Goods and Registered Suppliers) Regulations 2017 will be 
amended to introduce MELS and MEPS for three -phase VRF air -conditioners.  
Following the entry into force of this measure on 1 April 2021, all regulated three -phase 
VRF air -conditioner base units, to be supplied or for sale in Singapore must:  
• be registered;  
• be labelled with an Energy Label, and  
• meet MEPS requirements as shown below : 
MEPS Requirement for Three -phase VRF air -conditioner base units  
Integrated Energy Efficiency Rati o (IEER) ≥ 4.35  
where  
IEER = (0.020*COP 100%) + (0.617*COP 75%) + (0.238*COP 50%) + (0.125*COP 25%) 
and 
Coefficient of Performance x% (COP) = Total Cooling Capacity (kW)  
                                                        Effective Power input (kW)  
x% refers respective cooling capacity loading  G/TBT/N/SGP/54

  Regulated three -phase VRF air -conditioners are to be tested according to the following 
standards and conditions to determine t heir energy performance:  
• ISO 15042: Multiple split -system air conditioners and air to air heat pumps – testing 
and rating for performance ( https://www.iso.org/standard/63408.html ) 
• T1: Standard cooling capacity rating conditions for moderate climates  
• Cassette type indoor units and at least 2 units shall be used during test  
7. Objective and rationale, including the nature of urgent problems where 
applicable:   
Objective: For the purposes of environmental protection and conservation.  
Rationale: Space cooling accounts for a high proportion of electricity consumption in 
households and buildings. The introduction of MEPS for three -phase VRF air -conditioners 
will re duce energy consumption and result in lower emissions of greenhouse gases from 
space cooling. Energy labelling (MELS) will help users select more energy efficient models, 
reap lifecycle cost savings and contribute to the efforts to lower emission of greenh ouse 
gases.; Protection of the environment
