Code Development


The government of Singapore adopted the first building energy standards in 1979. The standards addressed thermal performance of the envelope as well as building controls (ventilation, cooling and lighting). Singapore’s more recent mandatory building energy code is Code for Environmental Sustainability of Buildings (the 2008 Building Control Act). The code largely adopted the minimum standards of the voluntary green building rating system, the Green Mark Scheme, originally introduced in 2005.

Revision Schedule Explanation

The Singapore energy code requirements have been revised several times since the 1st version was adopted in 1979. In 1989, a revision to the energy code was made. And In 1999, three codes of practice for buildings were updated: (1) Code of Practice for Energy Efficiency Standard for Building Services and Equipment, Singapore Standard CP24 (2) Code of Practice for Mechanical Ventilation and Air-conditioning in Buildings, CP13 and (3) Code of Practice for Artificial Lighting in Buildings, CP38.

Code Implementation - Compliance & Enforcement

Administrative/Enforcement Structures

The national government reviews energy audit reports and develops benchmarks and policies. Third-party assessors ensure that buildings are up to code. 

Compliance Checking on Design

Yes, compliance is checked on Design

Compliance Checking on Construction

NA, compliance varies by jurisdiction – refer to country information sheet for details

Compliance Checking on Pre-Occupancy

Yes, compliance is checked on Pre-Occupancy

Air Tightness testing

Yes, Air Tightness is tested

Commissioning before occupancy

Yes, commissioning is happening before occupancy

Commissioning after occupancy

Yes, commissioning is happening after occupancy

Compliance Software Residential

Yes, Software exists

Short description

Singapore has a detailed guidebook for enforcement of its energy code. In addition, since introducing performance-based compliance in 2000, software-based tools have appeared, such as those developed by the National University of Singapore (NUS).

Penalties for non-compliance

  • Refusal Permission to construct
  • Refusal Permission to occupy
  • Other

Other penalties

Fines can be applied for non-compliance

Incentives and Recognition program for compliance

  • Awards/Grants/Tax Breaks
  • Finance/Loans/Ratings

Short description

Singapore offers subsidies, grants and financing for building upgrades, such as Energy Efficiency Improvement Assistance Scheme (EASe) (up tp S$200,000, or about US $150,000 per facility or building); Grant for Energy Efficient Technologies; Design for Efficiency (DfE) Scheme; Innovation for Environmental Sustainability (IES) Fund; ehe Building Retrofit Energy Efficiency Financing (BREEF) scheme.

Capacity Building and Education

Awareness Raising

  • Awareness raising
  • Resourse kits
  • Compliance Training
  • Professional Curriculum

Short description

Singapore has a number of programs to build the capacity of stakeholders (government professionals, inspectors, designers, construction engineers) on building energy efficiency, such as Singapore Certified Energy Manager Programme & Training Grant, the National Energy Efficiency Conference, Green Mark Specialist Certification, Executive Development & Degree Programs.

Building materials

Building Materials Ratings

  • Reference standards included in codes
  • Tested by certified test labs

Short description

Singapore has a system to test, rate and label building materials for their energy properties. The Ministry of Environment launched the Singapore Green Labelling Scheme (SGLS) in 1992, which is now administered by the Singapore Environment Council (SEC). SGLS labels bricks, tiles, insulation, windows and many types of other materials (

Energy Performance Certificates

EPC Implementation

  • EPCs are referred to in codes -
  • EPCs replace codes in some areas

Short description

Since 2013, all buildings must annually submit general building information and energy consumption data (from utilities) to the Buildings Control Authority. Singapore has a mandatory Green Mark certification in place.
