   achieve energy savings of 58 percent when compared to the same building had it been designed to comply purely with energy efficiency regulations. Exploring the use of coloured building-integrated photovoltaics (BIPVs) which will be integrated with the administration building walls, it is replacing the need for ordinary facade cladding. Besides providing an alternative to conventional photovoltaics (PVs) for buildings with limited roof space, BIPVs can better manage energy demands of the building by providing a steadier power generation pattern throughout the day. The silent system that generates on-site electricity is estimated to generate 130,000 kWh of energy annually for this building when it is completed by Q4 2020.
In addition, to help building owners and developers source for innovative SLE technologies, BCA and Hitachi launched the Super Low Energy Building (SLEB) Smart Hub, the first digital knowledge portal for green buildings in the region. The initiative was unveiled at IBEW 2019.
The SLEB Smart Hub is an open database that collates and analyses green building
technologies such as air-conditioning, lighting, facade and renewable energy. Beyond being a data repository, its Smart Advisor recommends suitable green technologies and predicts the associated costs and energy savings, using cutting-edge big data analytics and artificial intelligence techniques based on a building’s current data set and user’s requirements. It allows building owners and designers to evaluate and source green technologies to transform buildings to attain high energy performance. This will ease the adoption of green technologies and support the national target to green 80 percent of buildings in Singapore by 2030. Close to 90 companies participated in the pilot phase and leveraged on building energy efficiency data to benefit their businesses.
Mr Cheng Tai Fatt, Managing Director of Built Environment Research and Innovation Institute, BCA, said: “SLEB Smart Hub offers a one-stop platform for building owners and designers to access the latest technological information and performance data of Green Mark buildings. This database, together with built-in artificial intelligence tools in the Smart Hub, enables users to improve their building
design and operations, thereby saving energy and providing a better indoor environment for occupants.”
Moving to the next phase of greening Singapore, BCA and the Singapore Green Building Council (SGBC) will co-create the next Singapore Green Building Masterplan (SGBMP 2020) with stakeholders from the public, private and people sectors, including Trade Associations and Chambers (TACs).
One of the key initiatives under the SGBMP 2020 is to review the mandatory minimum environmental sustainability standards for buildings. To support the push towards more energy efficient buildings, BCA plans to raise the minimum energy performance standards for both new and existing buildings in the coming years. BCA will engage stakeholders to work on the details through the SGBMP 2020 co-creation process.
BCA also intends to publish the energy performance data for all buildings with the building’s name, address and energy performance data made public on BCA’s website. This will allow building owners to benchmark their buildings’ energy performance against others, encourage them to retrofit to improve their buildings’ energy efficiency, and benefit from energy savings.
