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, a phased approach in disclosure of building energy performance was rolled out.
- Phase 1 - Mandatory submission and small sample voluntary disclosure (2014 - 2015)
- Phase 2 - Disclosure of anonymised building energy performance data (2016) and voluntary disclosure of building energy performance data (2017 - 2020)
- Phase 3 - Publication of building energy performance data (first dataset will be released in 2021)
In March 2020, BCA introduced the publication of energy performance data for buildings to facilitate benchmarking, and spur building owners to undertake retrofitting measures and improve the energy efficiency of their buildings. The implementation will be phased according to building type, starting with commercial buildings.
There will be no additional effort nor cost to the building owners beyond the current effort required to complete the annual mandatory submission. Building owners of commercial buildings will be given a 1-year notice before the 2020 energy performance data is released in 2021 through BCA Building Energy Submission System (BESS) and Singapore open data portal data.gov.sg.
