Two Taikoo Place also uses a market-leading Neuron Digital Twin system that utilises artificial intelligence to analyse and “learn” from large, historical data sets to optimise the efficiency of its building systems. This knowledge is then deployed to establish trends, forecast energy usage, optimise the running of a multitude of building systems, and detect faults, which allows for predictive maintenance. We will also install electricity sub-meters to facilitate electricity use monitoring and management by tenants. Partnership with National University of Singapore (“NUS”) on EIGHT STAR STREET Residential Development For our EIGHT STAR STREET residential development, we partnered with NUS in a first- of-its-kind whole lifecycle carbon assessment for a residential building. In addition to calculating upfront embodied carbon emissions, as we have done for our recent commercial projects – One Taikoo Place, Two Taikoo Place and Six Pacific Place – in this assessment, NUS also developed a 3D BIM model to simulate energy consumption and estimate the lifecycle operational carbon emissions for this 21-storey residential building with retail shops and amenities on the lower ground, ground and first floors.
