Building Energy Benchmarking

In 2013, BCA required all building owners to submit their energy performance data. The statistics and figures drawn from data collected through the Annual Mandatory Submission via the BCA Building Energy Submission System (BESS) forms the fundamentals of the annual BCA Building Energy Benchmarking Report (BEBR). This technical report provides transparency in the energy performance of buildings in Singapore. 

To improve transparency and raise awareness of buildings’ energy performance amongst building owners and industry stakeholders, a phased approach in disclosure of building energy performance was rolled out since 2014, from naming the top 10 for each subtype of commercial buildings with consent from the building owners, to allowing the building owners to opt to voluntarily disclose their building’s energy data to the public in 2017.

From 2021 onwards, to step up the pace of greening our buildings in support of the Singapore Green Building Masterplan, BCA will be publishing the names of buildings along with their energy related information. The public data can be found in these 3 platforms:
In the dataset, you can find out the energy performance of a building and the associated Green Mark certification if applicable. Some data fields include:
  • Energy Use Intensity (EUI) which indicates how much energy use per square metre for the building. The lower the EUI the less energy used per square metre which means better the energy performance of the building.
  • Central Air-conditioning Plant System Efficiency (kW/ton)
  • Green Mark Rating, Year of Award and Version awarded
The Green Mark certification scheme was launched in 2005 as a green building rating system designed to evaluate a building’s environmental impact and performance. Over the years, BCA reviews and updates the Green Mark scheme to keep pace with improvements in technology, building standards and industry best practices. More information on the Green Mark scheme can be found here

The publication of energy performance data for buildings aims to facilitate benchmarking, and spur building owners to undertake the necessary steps to improve energy performance and lower the carbon footprint of our buildings. This initiative will help up transit to a more sustainable, low-carbon Built Environment.
