1) The importance of energy efficiency 

Singapore has set ambitious targets to reduce its emissions intensity by 36% from 2005 levels by 2030, with buildings playing a crucial role as they account for more than one-third of the nation’s total electricity consumption.

Energy efficiency is crucial for reducing operational costs, minimizing environmental impact, and enhancing corporate social responsibility. By optimizing energy use, companies can significantly cut down on greenhouse gas emissions, contributing to the fight against climate change. In Singapore, where energy resources are limited, efficient energy use is particularly important for sustainable development.

The Building and Construction Authority (BCA) has been instrumental in driving this initiative through various schemes and masterplans aimed at greening 80% of the building stock by 2030​​.


2) Understanding Singapore’s energy efficiency regulations  

Singapore has implemented a robust framework to enhance energy efficiency across various sectors. The primary regulatory bodies overseeing these initiatives include the National Environment Agency (NEA) and the Building and Construction Authority.

The National Environment Agency of Singapore plays a crucial role in advancing energy efficiency across various sectors, including industry. Key initiatives include the Energy Conservation Act (ECA), which mandates energy management practices for energy-intensive companies, including regular energy audits and the submission of energy efficiency plans.

The Mandatory Energy Labelling Scheme (MELS) requires certain products, such as air-conditioners and refrigerators, to display energy labels, helping consumers make informed choices. Additionally, the Minimum Energy Performance Standards (MEPS) set the baseline for the energy efficiency of appliances and industrial equipment. The NEA also enforces greenhouse gas (GHG) emissions reporting, supporting Singapore’s climate goals.

Furthermore, the Resource Efficiency Grant for Energy (REG(E)) incentivizes investments in energy-efficient technologies, providing financial assistance to enhance energy savings. These measures collectively drive the industrial sector towards greater sustainability and compliance with national energy efficiency standards.


Key regulations include:

  1. Energy Conservation Act (ECA):  

The Energy Conservation Act is a legislative framework established to drive energy efficiency improvements and reduce energy consumption across various sectors, particularly focusing on buildings in Singapore. The ECA plays a crucial role in mitigating climate change by regulating and promoting energy conservation measures within the built environment.

This act mandates large energy users to implement energy management practices. Companies consuming more than 54 TJ (terajoules) of energy annually must appoint an energy manager, report energy use and greenhouse gas emissions and submit energy efficiency improvement plans.


  1. Green Mark Scheme:

Another key component of Singapore’s regulatory framework is the Green Mark Scheme.

Key steps to regulatory compliance

This initiative, launched by the Building and Construction Authority, aims to promote sustainability in the built environment. Buildings are assessed and rated based on their environmental impact and performance. The Green Mark 21 certification sets stringent standards for energy efficiency, water conservation, and it encourages buildings to minimize their overall environmental impact through sustainable construction and operational practices. Businesses that achieve this certification not only demonstrate their commitment to sustainability but also enjoy benefits such as reduced operational costs and enhanced corporate reputation.

This certification comes in several levels, reflecting the degree of environmental performance achieved by the building:


  • Certified: meets fundamental energy efficiency and sustainability requirements
  • Gold: goes beyond basic requirements with more significant sustainability efforts
  • GoldPLUS: shows substantial sustainability with comprehensive green features
  • Platinum: represents the highest standard of environmental performance


  1. Energy Efficiency Fund (E2F): 

The Energy Efficiency Framework is a critical component of the Super Low Energy (SLE) Building Technology Roadmap. It focuses on reducing energy consumption through a combination of passive and active strategies, smart energy management systems, and the integration of renewable energy sources. The primary goals of the E2F are to achieve significant improvements in energy efficiency, targeting 60 to 80% energy savings compared to 2005 levels by 2030.

In addition, the E2F provides financial support to companies investing in energy-efficient technologies and practices. It covers up to 50% of qualifying costs for energy efficiency projects, thereby lowering the financial barrier for companies aiming to reduce their carbon footprint.


  1. E2F usefulness for MEES (minimum energy efficiency standards) for industrial segments or BMS control:

The MEES in Singapore are designed to enhance the energy performance of industrial facilities. This initiative is akin to the GreenMark scheme but specifically tailored for the industrial segment. MEES focuses on hardware-based improvements, particularly targeting water-cooled chilled water systems in industrial settings. The standards mandate that these systems meet specific efficiency benchmarks, thereby reducing energy consumption and greenhouse gas emissions. By ensuring compliance with MEES, industrial facilities can significantly lower their operational costs and environmental impact, aligning with Singapore’s broader sustainability goals.

The MEES require industrial facilities to adhere to stringent energy performance criteria, which often involves installing Building Management Systems (BMS) to control and optimize energy use. The Energy Efficiency Fund is a valuable resource in this process. Under E2F, the project costs are shared between the customer and their service provider, with the National Environment Agency providing financial support after the project’s completion, based on the carbon savings achieved.

This funding mechanism encourages the adoption of energy-efficient technologies, such as BMS solutions, which are specifically designed to support systems like our predictive control solution, thereby enhancing the overall energy management and sustainability of industrial operations.
