Find out about BCA’s Mandatory Energy Improvement (MEI) regime for energy-intensive buildings, covering compliance requirements and audits.

Last updated on 2 September 2026

Background

The Mandatory Energy Improvement (MEI) regime was introduced through amendments to the Building Control Act on 10 Sep 2024 to support Singapore's move towards a low-carbon built environment. This regime aims to help building owners enhance their energy performance and reduce operational costs, while contributing to our national commitment to achieve net-zero emissions by 2050.  

Applicability

The MEI regime will apply to energy-intensive buildings with a Gross Floor Area (GFA) of 5,000 m² or more. This includes:  

  • Commercial buildings (offices, hotels, retail buildings)

  • Healthcare facilities 

  • Institutional buildings (educational, civic, community, and cultural institutions)

  • Sports and recreation centres 

  • Mixed development comprising of the above

Key Requirements

Under the MEI regime in Building Control (Amendment) Act 2024 gazetted on 11 Oct 2024, building owners of energy-intensive buildings must: 

  • Engage a qualified professional (“Specified Individual”)* within 90 days to conduct an energy audit of the building and its systems

  • Appointed Specified Individual need to develop an Energy Efficiency Improvement Plan (EEIP) with proposed measures to reduce energy consumption. The completed audit report (which includes the EEIP) must be submitted to BCA within 1 year from the issuance of the MEI audit notice. 

  • Implement measures within 3 years from EEIP submission date to reduce the building’s energy consumption by 10% from the average EUI from the past 3 years before the notice. 

  • Maintain the improved energy performance over a period of one year from completion submission date and submit a maintenance report within 3 months after the last day of the maintenance period. 

These steps are designed to enhance energy efficiency and contribute to Singapore's sustainability goals.
