In line with the Smart City vision of the HKSAR Government, making use of innovation and technology in the built environment is the key to achieving building energy efficiency and sustainable development. The smart city market is expected to grow continuously with the support of the Government, as highlighted in the recently released “Hong Kong Smart City Blueprint” (ITB, 2018). Besides the HKSAR Government has set an ambitious carbon intensity reduction target of 65% to 70% by 2030 using 2005 as the base, which is equivalent to 26% to 36% absolute reduction and a reduction to 3.3-3.8 tonnes on a per capita basis (EB, 2018). Given the dominance of air-conditioning (AC) systems in building energy consumption, and of buildings in Hong Kong’s overall energy use and greenhouse gas (GHG) emissions, ensuring AC systems are run at the highest possible energy efficiency is crucial to realisation of Hong Kong’s GHG emission reduction target. Greater utilisation of building data to serve this purpose is, therefore, a necessary strategy to take. The data-driven approach adopted in the design of the platform makes it easy to deploy without replacing the costly central equipment or disrupting operations.
