The programme was announced by Lawrence Wong, Minister for National Development and Second Minister for Finance, Singapore, who was guest-of-honour at the opening of Singapore Green Building Week (SGBW) 2018.
Hugh Lim, BCA CEO, said: “We have come a long way in our environmental sustainability journey. To kickstart the next wave of our green building movement, BCA is working with the industry professionals to deliver cost-effective super low energy buildings which can achieve a minimum of 60% energy efficiency improvement over the 2005 building codes, when the BCA Green Mark was first introduced. Beyond this, we are embarking on more rigorous research and innovation to further push the frontier for green buildings to achieve up to 80% energy efficiency improvement.
"By setting such new performance benchmarks, Singapore can play an important role in mitigating climate change and doing our part as a responsible global citizen. We hope more building owners and developers will join us as we work towards the common goal to shape a greener built environment that benefits Singaporeans.”

SLE Challenge
An SLE Challenge inviting developers to take the lead in developing SLE buildings through good designs and cost-effective technologies. So far, more than 10 developers and building owners have voluntarily pledged their commitment to achieve at least one SLE project in the next five years.
For instance, the Defence Science and Technology Agency (DSTA) has worked with the Army to achieve a high standard of energy efficiency for building facilities in Kranji Camp and Seletar Camp*, while still meeting operational requirements. For Kranji Camp building, sensors help to automatically lower artificial lighting levels when there is sufficient sunlight, thus conserving energy. Solar panels are installed on the roofs of both buildings to convert sunlight to electricity, generating sufficient energy to meet all their requirements.
Green Mark for SLE
To recognise these SLE projects, BCA has introduced the new Green Mark for SLE. This voluntary certification framework for SLE buildings adds on to the BCA Green Mark scheme, and supports the net zero energy aspiration in tropical and sub-tropical regions.
SLE Buildings Technology Roadmap
The SLE Buildings Technology Roadmap to develop cost-effective solutions that push the limits of energy-efficiency ratings and help achieve the target of up to 80% energy efficiency improvement over 2005 levels.
An SLE building with 60% energy efficiency improvement is technically feasible with best-in-class technologies today, but more research, development and demonstration (RD&D) is needed to push the boundaries to 80% energy efficiency improvement, and to do so in a cost effective way.
Keppel Land is one such developer who has committed to pilot various emerging technologies at its BCA Green Mark Platinum-certified development, Keppel Bay Tower, with a view to replicate the implementation of these technologies to rejuvenate its other commercial buildings. Keppel Land will demonstrate various technologies within Keppel Bay Tower, including:
Smart lighting
The smart lighting system utilises occupancy sensors which will allow seamless transition in lighting levels according to building occupancy. The fully-autonomous system will be implemented in seven levels of the building.
Climate control based on analytics
Climate control based on analytics
Integrated sensors are used to capture occupants’ activities and comfort levels based on which an analytical model will be derived to predict and optimise air-conditioning operations to improve energy efficiency.
Intelligent building control
Intelligent building control
The smart building management system, which will be implemented throughout the entire building, uses a simulation model together with available building data for energy optimisation, predictive maintenance and fault detection. This technology employs a high-performance physics-based simulation engine that utilises machine learning and artificial intelligence to improve data analytics and control. This will reduce the downtime and resources required for Keppel Land to maintain and operate the development.
*Both developments are on track to achieve Zero Energy Building status under the new BCA Green Mark for SLE, as the framework provides pathways to meet either Super Low Energy or Zero Energy Building.
