  Climate change is a global concern. In public sector developers demonstrate best-in-
class energy performance while maintaining cost effectiveness.
Samwoh Smart Hub incorporates energy and water saving measures in its design, including double glazed windows on the north and south facades to harness natural daylight, and a windowless design on the east and west facades to reduce heat absorbed by the building. The project will also have on-site water recycling measures and leverage a smart Building Management System (BMS) and Facility Management to optimise utility management and consumption. Together with high-yield solar panels which will produce about 110 percent of the building’s energy consumption, the Hub targets to save close to S$180,000 a year in overall utility bills. The ambitious development, a pilot under the BCA Green Mark Super Low Energy programme is slated for completion by 2020, and will set the precedence for future positive energy buildings here.
The Nanyang Technological University, Singapore (NTU Singapore) sets a high standard with eight campus projects such as its sports hall, The Wave, the School of Humanities, the School of Social Sciences and the Wee Kim Wee School of Communication and Information. NTU implemented a variety of energy saving initiatives such as the campus-wide solar energy harvesting system that generates 5.9MWh/ year and a ‘Passive Displacement Cooling’ system which uses convection to keep rooms cool. NTU will also progressively roll-out Smart Integrated Building Management systems that will see up to 10 percent energy savings from air-conditioning units.
As part of advancing the Green Building agenda, BCA has been supporting research and innovation efforts to push the envelope and
Singapore, buildings account for over
20 percent of Singapore’s emissions. The greening of buildings is one of our key efforts in building more sustainably and in mitigating our emissions. Singapore has set a target of greening 80 percent of the nation’s building stock and has committed to reduce carbon emissions by 36 percent from 2005 levels by 2030.
To drive the energy efficiency of buildings, the Building and Construction Authority (BCA) has been working closely with industry stakeholders towards the target of greening Singapore. Since 2005, BCA has rolled out a suite of initiatives such as Green Building Masterplans, Green Mark schemes and the Green Buildings Innovation Cluster (GBIC) programme. Various government agencies have embarked on several national sustainability programmes such as the Sustainable Singapore Blueprint, Smart Nation initiative and SolarNova, driving a multifaceted approach towards the development and adoption of sustainable technologies and solutions for the built environment.
On 5 September 2018, BCA launched the Super Low Energy (SLE) Building programme to encourage firms to go beyond the existing Green Mark Platinum standards and achieve best-in-class building energy performance in a cost-effective manner.
Progressive developers agreed to take the lead in developing close to 20 SLE buildings through good designs and cost-effective technologies. To recognise these SLE projects, BCA introduced a new Green Mark for SLE.
As of 2019, there are 17 GM – SLE buildings in Singapore, amongst which are recognised forerunners such as Samwoh Smart Hub, NTU and NUS under 2019’s inaugural GM-SLE Awards. The projects from seven private and
