IES is pleased to have sponsored and presented at IBPSA-Singapore’s first seminar, titled “Pushing Next Frontiers in Green Building Design”. With the aspiration to share the next-generation frontiers in green building design, the seminar hosted a thrilling range of speakers to share their approaches in converging the industry’s knowledge gap. The seminar had over 60 participants, ranging from building practitioners, environmentally sustainable design consultants, architects, as well as researchers and students from relevant institutions.

Mr Rohan Rawte, IES Head of Asia, was delighted to share his presentation, titled “Calibrated Digital Twins for the Built Environment”. In his sharing, Rohan highlighted how building performance simulation has the powerful capability to predict building performance as it uses fundamental physics to simulate scenarios even when no prior data exists. Machine Learning shows great potential in the domain as it can trawl through large databases of historical information to extrapolate ‘answers’. A known solution from Integrated Environmental Solutions today, iSCAN enables this hybrid approach, which combines both these techniques to give users the best-of-both-worlds in capability. In his presentation, Rohan summed up the immense benefits of the digital twin:

“This digital twin uses the hybrid approach to give users highly accurate calibrated digital twins. Such digital twins can then be used to optimise building performance, without interfering with the existing operations of the building or needing any invasive auditing methods.”

IBPSA-Singapore is a Chapter of the International Building Performance Simulation Association (IBPSA). It is a non-profit international society of building performance simulation researchers, developers and practitioners, dedicated to improving the built environment. IES is proud to support IBPSA-Singapore’s mission in promoting the science and technology of building performance simulation to improve the design, construction, operation, maintenance and refurbishment of buildings.
