Integrated Smart High-rise Building Energy Modelling (ISHBEM)


Buildings together contribute to over a third of the world‟s energy consumption and greenhouse gas (GHG) emissions. Buildings in Hong Kong account for almost 92% of electricity use and 60% of GHG emissions in the city (EMSD, 2014), far exceeding the world averages. There is therefore a very challenging context for reducing building energy consumption in Hong Kong. Reducing building energy consumption has been a focus in the HKSAR Government Policy Address and building energy codes. In the 2007-08 Policy Address the Chief Executive (2007) of the Government stated that Hong Kong pledged to seek to achieve a reduction in energy intensity of at least 25% by 2030 compared to the 2005 baseline. The recently released „Energy Saving Plan for Hong Kong‟ set the targets to achieve energy intensity reduction by 40% by 2025 and to reduce electricity use by government buildings by 5% by 2020. However, despite the strong policy commitment, there is little understanding of the accuracy of energy modelling and the energy performance gap of buildings in Hong Kong. This project aims to develop a process framework for achieving integrated smart high-rise building energy modelling (ISHBEM), which will help to improve the accuracy of predicting buildings‟ energy use and minimize the gap between as-designed and as-occupied building energy performance.
