Green Chillers and Energy Efficiency

Project description

Programme title: Green Chillers Nationally Appropriate Mitigation Action (NAMA)
Commissioned by: German Federal Ministry for the Environment, Nature Conservation and Nuclear Safety (BMU)
Country: Indonesia
Lead executing agency: Directorate General of New, Renewable Energy and Energy Conservation (DG NREEC), Ministry of Energy and Mineral Resources Republic of Indonesia
Overall term: 2014 to 2019

Energy consumption from Refrigeration and Air Conditioning (RAC) sector in Indonesia was 81.8 terawatt hours (TWh) in 2015 and is projected to increase to 149.4 TWh by 2030. As a result of this energy use, Greenhouse Gas (GHG) emissions from the RAC sector in 2015 was 77.31 metric tons of carbon dioxide (mTCO2), meaning that the RAC sector’s share in overall energy-related emissions in Indonesia corresponds to approximately 15.4 per cent of the country’s energy-related GHG emissions. However, by using natural refrigerants and modern technology, 26.6 TWh can be saved and GHG emission can be decreased by 35 mTCO2 by 2030. 


The project has promoted the use of natural refrigerants and energy efficient technology inthe Indonesian RAC market.

The project assists the Government of Indonesia; particularly Ministry of Energy and Mineral Resources, in establishing appropriate incentive mechanisms for the implementation of efficient RAC technology in selected areas. To demonstrate the advantages of green cooling technology, pilot projects will be implemented and RAC technicians will be trained and nationally certified in the safe and efficient use of how hydrocarbons have an impact on the RAC sector.

The project is structured into four focus areas: 

  • NAMA strategy development: The design of a sector-specific NAMA, agreed with the main stakeholder groups and embedded in the strategy of Ministry of Energy and Mineral Resources (MEMR) to achieve Nationally Determined Contribution (NDC) target on energy sector by 2030.
  • Establishment of appropriated framework conditions: Supporting Policy-makers in creating tailor-made incentives to enhance the market entry of green technology as well as revision of the existing national Standards on Performance and Safety. 
  • Implementation of pilot projects: Installation of exemplary reduction measures to promote the introduction of this energy efficient and climate-friendly technology.
  • Capacity building: Establishment of a training and certification scheme for RAC professionals covering the planning, execution and maintenance of innovative cooling systems. 


  • Published report on the first comprehensive GHG inventory RAC sector in Indonesia
  • NAMA (Nationally Appropriate Mitigation Action) concept on Indonesia’s Green Cooling Program (IGCP) has been developed
  • Published report on Supporting Policies and Incentives for Accelerating Energy Efficiency of RAC in Indonesia
  • Installation of Pilot Projects: 
  • Chiller 197,61 kW at the Art Center, University of Indonesia;
  • Chiller 43,63 kW at the Polytechnic, Bali;
  • Cold Storage 1,663 kW at the Polytechnic, Bandung;
  • Roof top AC 60,6 kW and Ducted split 33 kW at the Pertamina R&D, Pulogadung;
  • 2 Chillers each 231.9 kW at the Production building of PT, Phapros.
  • Certification and Training scheme for Cooling Technicians in safe and energy efficient use of hydrocarbon refrigerants. Currently, 87 technicians have been trained in which 68 were nationally certified. 
  • Publication of Indonesian National Standards (SNI):
  • SNI ISO 817-2018 on refrigerant – designation and safety classification, 
  • SNI 6500-2018 on fixed installation refrigeration system - safety and environmental requirements,
  • SNI 8476-2018 on method of rating and testing for performance of liquid chilling packages using the vapour compression cycle.
