Energy Benchmarking Tool for Low-Carbon Transformation in Hong Kong: A Scientific Approach and Its Practical Applications
World energy consumption has increased rapidly in recent years and shows no indication of slowing.In Hong Kong,this situation is more critical due to its high demand in urban energy consumption and scarcity of natural resources within its jurisdiction.To push Hong Kong to the very forefront of the fight against climate change and form a low-carbon urban transformation,energy benchmarking is one of the most effective ways to set up industrys best practice and achieve sustainable development.While there exist a few benchmarking programmes worldwide,such as ENERGY STAR Portfolio Manager in the US,NABERS in the Australia,they are limited to benchmarking the existing buildings without customised improvement advice to enhance energy efficiency.Hong Kong,with its extremely high-density urban form,starts to develop its own benchmarking tools in recent years for the unique built environment,some early attempts include HK BESTOO developed by Hong Kong Green Building Council(HKGBC)and Energy Utilisation Indexes and Benchmarks developed by Electrical and Mechanical Services Department(EMSD).In order to accelerate the low-carbon urban transformation,a more comprehensive benchmarking system is needed to evaluate and improve the whole building energy performance.It will surpass the existing benchmarking programmes around the world by assessing the building to the system-level details and provide ratings based on different building system types.Additionally,the worlds first “What-If Function will provide the building owner with tailor-made suggestions to improve the building energy performance.This paper reviews the state-of-the-art methods in building energy benchmarking and proposes a new benchmarking system specifically catering to Hong Kongs unique built environment to promote the low-carbon urban transformation in Hong Kong.This project was initiated by the HKGBC with the aim to improve building energy performance in Hong Kong.Arup was appointed as the consultant to undertake studies.
