National Energy Efficiency Standard (SNI) for Buildings
- Energy conservation for building envelope – SNI 03-6389-2011
- Energy conservation for air conditioning system in building – SNI 03-6390-2011
- Energy conservation for lighting system in building – SNI 03-6197-2011
- Energy audit procedure for building – SNI 03-6196-2011
Indonesia has four energy standards for buildings (Standar Nasional Indonesia/SNI), which cover the building envelope, air conditioning, lighting and building energy auditing.
Indonesia already has strong national policies on energy efficiency. The next step is to establish complete, mandatory codes that will set strict guidelines for efficiency in buildings. Updating the commercial code and establishing residential codes will lead to greater compliance and efficiency in buildings, and is the easiest way to achieve the goals set out in the Energy Efficiency Plan. The codes can be rolled into the National Building Code (which currently outlines seismic design standards but discusses lighting and ventilation) or created as separate entities.
Indonesia Seismic Resistance Design Standard For Buildings
These are structural codes for buildings based on seismic codes; unknown to what extent the code covers energy efficiency. The Seismic Resistance Design Standard for Buildings (SNI 03-1726-2012) is Indonesia’s national building code and is implemented regionally. It is mainly concerned with codes based on loads that can withstand seismic forces. However, it is important to note that the code gives control over standards for lighting and ventilation to local governments.

- Law on Energy (2007)
The 2007 Law on Energy, which was approved by the legislative and executive branches of Indonesian government, gives the government the power to manage all of the country’s energy use. This is meant to improve the energy security of the country, make sure that all sectors use energy efficiently, and promote the use of sustainable energy.

In 2005, Indonesia launched an update to its National Master Plan for Energy Conservation (RIKEN), which set the goal of decreasing energy intensity by at least 1% per year until 2025. The master plan was first passed in 1995, establishing the need for further implementation of specific energy conservation programs and energy audits and reports.
As an ASEAN member, Indonesia adopted voluntary commercial energy codes in 1992. The code applied to building envelope, lighting, and HVAC. Unfortunately, it was believed that the codes were not understood or adhered to by builders and designers in Indonesia. USAID believed that if the codes were enforced, Indonesia could have attained a 20% energy savings.
The Indonesian National Standard SNI 03-6389-2000 adapted the 1983 Singapore’s Handbook on Energy Conservation and limited the Overall Thermal Transfer Value (OTTV) of the building envelope to 45 Watt/m2. In 2008, the Singapore’s Building and Construction Authority (BCA) shifted to Envelope Thermal Transfer Value (ETTV) value of 50 Watt/m2, while SNI 03-6389-2011 continues to use OTTV.
